Quick Answer: To keep hot tub water clean, safe, and clear, maintain a pH of 7.2–7.8, total alkalinity of 80–120 ppm, and sanitizer levels of 3–5 ppm chlorine or 4–6 ppm bromine. Balanced water chemistry prevents cloudy water, bacteria growth, scaling, corrosion, and costly spa equipment damage.
Hot tub water chemistry is the single most important part of spa ownership. Most heating failures, pump issues, skin irritation, and water problems begin with unbalanced chemistry.
This guide explains exactly how to test, balance, and maintain spa water properly, especially in Colorado mountain environments like Aspen and Basalt.
Why Hot Tub Water Chemistry Matters
Hot tubs operate in warm temperatures, which makes water chemistry more sensitive than pools.
When spa water is unbalanced, it can lead to:
Cloudy or foamy water
Strong chemical odors
Skin and eye irritation
Scale buildup on heaters and jets
Corrosion of internal components
Reduced sanitizer effectiveness
Increased risk of bacteria growth
In short, balanced water protects both your health and your hot tub investment.

Step-by-Step: How to Balance Hot Tub Water Correctly
Always balance spa water in the correct order. Fixing chemicals out of sequence causes frustration and unstable readings.
Step 1: Test Your Water 2–3 Times Per Week
Use:
Spa test strips
Liquid drop test kits
Professional water testing (recommended monthly)
Test regularly because hot tubs change faster than pools.
Aspen Tip: Mountain water sources often contain minerals that affect hardness, so consistent testing is especially important.
Step 2: Adjust Total Alkalinity First
Total alkalinity is the foundation of water balance.
It controls how stable your pH remains.
If alkalinity is too low:
pH swings rapidly
Water becomes corrosive
Skin irritation increases
If alkalinity is too high:
Water becomes cloudy
Scale forms on equipment
pH becomes difficult to adjust
Target Range: 80–120 ppm
Step 3: Balance pH Second
pH measures how acidic or basic your spa water is.
The ideal pH keeps water comfortable and allows sanitizer to work properly.
Target pH Range:
7.2–7.8
Ideal sweet spot: 7.4
If pH is too low:
Water becomes acidic
Equipment corrosion occurs
Eye irritation increases
If pH is too high:
Sanitizer becomes less effective
Cloudiness increases
Scale forms faster
Step 4: Maintain Proper Sanitizer Levels
Sanitizer is what kills bacteria and keeps spa water safe.
Hot tubs require consistent sanitizer because warm water accelerates bacterial growth.

Quick Answer: Hot tub winterization in Aspen, Colorado requires draining the spa, blowing all water out of plumbing lines, protecting pumps and heaters from freezing, and securing proper insulation before temperatures drop below 20°F. In high-altitude climates like the Roaring Fork Valley, even a single overnight freeze can crack pipes, damage equipment, and lead to repairs costing $1,000 or more.
If you own a hot tub in Aspen or Basalt, winterization is one of the most important seasonal steps you can take to protect your investment and prevent emergency breakdowns during Colorado’s coldest months.
This guide explains exactly when to winterize, how to do it safely, what mistakes to avoid, and when to call a professional spa technician.
Why Hot Tub Winterization Is Essential in Aspen and Basalt
Hot tubs in mountain towns face harsher conditions than most areas of the country.
Aspen-area winters bring:
Overnight temperatures below 0°F
Rapid freeze expansion in plumbing lines
Heavy snow accumulation on spa covers
Dry air evaporation lowering water levels
Higher likelihood of winter power outages
In Pitkin County and the Roaring Fork Valley, freeze-related spa damage is one of the most common winter repair issues.
What Happens If a Hot Tub Freezes?
When water freezes, it expands. That expansion can:
Crack PVC plumbing
Split pump housings
Destroy heater manifolds
Cause hidden leaks under the cabinet
Require major part replacements
Even if the spa looks fine externally, freeze damage often appears weeks later as leaks or heating failures.
Winterize or Keep Running? The Most Important Decision
Before winterizing, determine whether your spa will be used during winter.
Option 1: Keep the Hot Tub Running All Winter (Most Common in Aspen)
This is best if:
You use the spa weekly
Someone is checking water chemistry regularly
The home is occupied
Power is reliable
Running your spa through winter is safe when properly maintained.
Option 2: Full Winterization Shutdown (Best for Vacation Homes)
Winterization is recommended if:
The home will be vacant for weeks
You travel frequently during winter
The spa cannot be monitored
You want maximum freeze protection
Many second-home owners in Aspen choose full winterization for peace of mind.
When Should You Winterize a Hot Tub in Colorado?
Best timing: Before consistent freezing weather begins.
In Aspen, that typically means:
Late October through November for seasonal shutdown
Immediately before extended winter travel
Anytime the spa will be unused for more than 2–3 weeks
Do not wait until temperatures drop below freezing, because trapped water becomes much harder to remove safely.
Step-by-Step Hot Tub Winterization Checklist (Aspen-Proof Method)
Below is the complete professional process used for Colorado cold climates.
Step 1: Turn Off Power at the Breaker
Always shut off power completely.
This prevents:
Heater burnout
Pump activation while empty
Electrical hazards during draining
Never rely on the control panel alone. Use the breaker.
Step 2: Drain All Water From the Spa Shell
Drain the tub fully using:
Built-in drain valve
Submersible pump (faster)
Make sure the footwell is completely empty.
Tip: Aspen’s dry air can cause faster evaporation, but draining must still be complete.
Step 3: Blow Out Plumbing Lines (Most Critical Step)
This is where most DIY winterizations fail.
Even a small amount of water left in lines can freeze.
You must remove water from:
Jet plumbing
Pump unions
Heater lines
Air blower lines
Waterfall features
Recommended tool: High-volume blower or professional spa vac system.
A shop vac can work, but often does not fully clear deep plumbing runs.
Step 4: Open Pump Unions and Drain Equipment
Spa pumps hold hidden water.
A technician will typically:
Loosen pump unions
Drain water from pump housings
Clear heater chambers
Empty circulation lines
This step prevents the most expensive freeze damage.
Step 5: Remove and Clean Spa Filters
Filters should never be left wet inside the spa all winter.
Steps:
Remove filters
Rinse thoroughly
Soak in filter cleaner
Allow to dry completely
Store indoors
Step 6: Add Spa-Safe Antifreeze (Only If Needed)
In some cases, technicians use non-toxic antifreeze in plumbing.
Important rules:
Only use antifreeze labeled for spas
Never use automotive antifreeze
Only apply after lines are blown out
Antifreeze is a backup, not a replacement for proper draining.
Step 7: Clean and Dry the Spa Interior
Before closing the tub:
Wipe down shell surfaces
Remove standing moisture
Clean the waterline
Ensure footwell is dry
This prevents mold and odor buildup.
Step 8: Secure the Cover for Aspen Snow Loads
Aspen winters require stronger cover protection.
A winter-ready cover should be:
Fully insulated
Locked down tightly
Free of gaps
Cleared after heavy storms
Snow buildup can collapse weak covers and allow heat loss.

Owning a swim spa is an investment in year-round wellness, relaxation, and fitness. When temperatures drop, proper seasonal care becomes essential. Knowing how to winterize a swim spa helps protect your equipment, plumbing, and shell from freeze damage, costly repairs, and unnecessary wear.
Whether you plan to keep your swim spa running through winter or shut it down completely, the steps below will help you prepare with confidence.
Why Winterizing a Swim Spa Is Essential
Cold weather presents unique challenges for swim spa owners, especially in mountain and high-altitude regions where temperatures can fluctuate quickly. Water expands as it freezes, and even small amounts trapped in plumbing lines, pumps, or fittings can cause cracks or internal damage.
Key benefits of winterizing your swim spa include:
Preventing freeze damage to pipes, pumps, and jets
Extending the lifespan of equipment and components
Before you begin, decide whether you will fully winterize the swim spa (shut it down) or prepare it to operate safely throughout the winter.
Decide Whether to Shut Down or Keep Running
Not all swim spa owners choose to drain their unit for winter. Many modern swim spas are designed to operate year-round when properly maintained and insulated. However, full winterization may be the best option in certain situations.
You may want to shut down and winterize if:
You will not be using the swim spa during winter
Power availability is unreliable
You plan to be away for extended periods
The swim spa is older or less insulated
Energy costs are a concern
If you choose to keep the spa running, winter preparation still involves important steps to maintain consistent heat, balanced water chemistry, and freeze protection.
Gather Tools and Supplies Before You Start
Preparation makes the winterization process smoother and more effective. Before you start, gather the tools and supplies you will need.
Common winterization supplies include:
Garden hose
Submersible pump or spa drain hose
Wet-dry vacuum
Non-toxic RV or marine antifreeze (never automotive antifreeze)
Spa filter cleaner
Clean towels or rags
Water testing kit
Screwdriver or basic hand tools
Protective gloves
Having everything ready reduces the chance of missed steps that could lead to freeze damage.
Step 1: Power Down the Swim Spa Safely
Before draining or servicing any component, turn off power at the breaker. This is critical for safety and helps prevent damage to pumps and heaters when water levels drop.
Make sure:
All control panels are powered off
The GFCI breaker is switched off
The spa cannot cycle automatically during servicing
Never attempt to drain or winterize a swim spa while power is still connected.
Step 2: Drain the Water Completely
Draining the swim spa thoroughly is one of the most important steps. Even small amounts of leftover water can freeze and cause damage.
Steps to drain properly:
Attach a hose to the drain valve or use a submersible pump
Direct water away from the foundation and surrounding areas
Open air valves and diverter valves to help water escape
Allow sufficient time for full drainage
Once drained, inspect the shell and interior surfaces for buildup or residue that should be cleaned before storage.
Step 3: Remove and Clean the Filters
Filters should not be left in the swim spa during winterization. Remove them carefully and clean them thoroughly using a dedicated spa filter cleaner.
After cleaning:
Rinse completely and allow to dry
Store in a clean, dry indoor location
Inspect for wear or damage and replace if needed
Clean filters help improve performance at spring startup and can extend system life.
Step 4: Blow Out the Plumbing Lines
This step is essential and often overlooked. Even after draining, water can remain trapped in plumbing lines, jets, and pumps.
To remove trapped water:
Use a wet-dry vacuum on each jet, suction fitting, and drain opening
Alternate between vacuum and blower modes if available
Continue until no water mist or droplets appear
Pay special attention to swim jets and therapy jets, as these lines often hold more water.
Step 5: Add Antifreeze to Plumbing Lines
After blowing out the lines, add non-toxic antifreeze designed for RV or marine use. Never use automotive antifreeze, as it is toxic and unsafe for spa systems.
Where to add antifreeze (as appropriate for your model):
Jet openings
Pump housings
Filter compartments
Any low points in plumbing
This provides an added layer of freeze protection during extreme cold.
Step 6: Clean and Protect the Interior Shell
Before closing the swim spa, clean all interior surfaces to help prevent stains, odors, and buildup over winter.
Recommended steps:
Wipe down the shell with a spa-safe cleaner
Remove any debris from footwells or seating areas
Dry surfaces thoroughly with towels
A clean shell makes spring startup easier and helps protect the finish.
Step 7: Secure and Insulate the Cover
A high-quality, well-fitted cover is critical for winter protection. Inspect the cover before closing the spa.
Check for:
Cracks or waterlogged foam cores
Torn vinyl or broken straps
A proper seal around the edges
For extra protection, consider adding a thermal blanket under the cover. Secure all straps tightly to reduce wind damage and heat loss.
Step 8: Protect the Cabinet and Exterior Components
Cold temperatures, snow, and ice can affect the exterior of your swim spa. Protecting the cabinet and maintaining airflow can help prevent moisture issues and component damage.
Exterior protection tips:
Clear debris from vents and access panels
Ensure proper drainage around the base
Avoid piling snow against the cabinet
Use a breathable spa cover protector if needed
Good airflow helps reduce moisture buildup and protects internal components.
Ongoing Winter Care for Active Swim Spas
If you choose to keep your swim spa running during winter, maintenance remains essential.
Key winter care practices include:
Maintaining water temperature above freezing at all times
Testing water chemistry regularly
Keeping filters clean and free of ice
Checking the cover seal frequently
Monitoring for error codes or unusual noises
Many premium swim spas are designed to handle cold climates when properly cared for.
Common Winterization Mistakes to Avoid
Even experienced spa owners can make winterization mistakes. Avoid these common issues to protect your investment.
Leaving water in plumbing lines
Forgetting to turn off power completely
Using the wrong type of antifreeze
Skipping filter removal
Relying on the cover alone for freeze protection
Professional service can help prevent these errors, especially in regions with severe winter conditions.

Infrared saunas have become increasingly popular among homeowners and wellness-focused individuals looking for a convenient way to relax, recover, and support overall health. Unlike traditional saunas that heat the surrounding air, infrared saunas use infrared light to warm the body directly.
This difference leads many people to ask an important and practical question: How often should you use an infrared sauna?
The answer depends on your health goals, experience level, and how your body responds. With the right approach, infrared sauna use can become a safe, effective, and sustainable part of your wellness routine.
Understanding Infrared Sauna Therapy
Before deciding on frequency, it helps to understand how infrared saunas work. Infrared heat penetrates the skin more deeply than traditional sauna heat, allowing the body to warm efficiently at lower ambient temperatures.
Because of this, many users find infrared saunas more comfortable and easier to use regularly. They are commonly used for relaxation, muscle recovery, circulation support, stress reduction, and general wellness.
General Guidelines for Infrared Sauna Frequency
There is no universal rule that applies to everyone, but most healthy adults can safely enjoy infrared sauna sessions multiple times per week.
Beginners: 2–3 sessions per week
Intermediate users: 3–4 sessions per week
Experienced users: 4–6 sessions per week or daily, depending on tolerance
Starting slowly allows your body to adapt to heat exposure while reducing the risk of dehydration or fatigue. Listening to your body is more important than following a rigid schedule.
How Your Health Goals Affect Sauna Frequency
Your personal wellness goals play a major role in determining how often you should use an infrared sauna.
For relaxation and stress relief, two to three sessions per week are often sufficient. These sessions can help promote better sleep and provide a calming break from daily stress.
For muscle recovery and athletic performance, many active individuals benefit from three to five sessions per week to support circulation and ease muscle soreness.
Those focused on general wellness and circulation often find that consistent use three to four times per week delivers noticeable benefits without overtaxing the body.
Daily Infrared Sauna Use: Is It Safe?
Many healthy adults can safely use an infrared sauna daily when sessions are kept within reasonable limits and hydration is prioritized. Typical session lengths range from 20 to 45 minutes, depending on temperature and individual tolerance.
You stay well hydrated
You feel refreshed rather than exhausted afterward
You do not experience dizziness or headaches
You have no medical conditions that limit heat exposure
If you are new to infrared saunas, it is generally best to build up gradually rather than starting with daily sessions.
Session Length and Temperature Considerations
Frequency should always be considered alongside session length and temperature. Longer or hotter sessions place greater demand on the body and may require more recovery time.
Most infrared saunas operate between 120 and 150 degrees Fahrenheit. Beginners often start with sessions lasting 15 to 20 minutes at lower temperatures, then gradually increase to 30 or 40 minutes as tolerance improves.
Longer sessions may require fewer weekly visits, while shorter sessions can often be enjoyed more frequently.
Signs You May Be Overusing an Infrared Sauna
While infrared saunas are generally well tolerated, it is possible to overdo it.
Persistent fatigue or weakness
Headaches after sessions
Dizziness or lightheadedness
Trouble sleeping
Dehydration despite drinking water
If you notice these symptoms, consider reducing frequency, shortening sessions, or lowering the temperature. Rest days can help your body recover.
Hydration and Recovery Are Essential
Proper hydration plays a critical role in how often you can safely use an infrared sauna. Sweating leads to fluid loss, especially with frequent use.
Drink water before your session
Sip water during longer sessions if needed
Rehydrate immediately afterward
Use electrolytes if you sweat heavily
Adequate rest and balanced nutrition also support recovery and long-term consistency.
Medical Considerations
Certain medical conditions may affect how often you should use an infrared sauna. Individuals with cardiovascular issues, low blood pressure, pregnancy, or other health concerns should consult a healthcare professional before starting a routine.
Making Infrared Sauna Use Sustainable
Consistency matters more than intensity. Creating a schedule that fits your lifestyle increases the likelihood of long-term success.
Many users pair sauna sessions with stretching, meditation, or light exercise. Evening sessions often support relaxation, while morning sessions may help promote energy.
Infrared Saunas Versus Other Heat Therapies
Some people alternate infrared sauna use with traditional saunas, steam rooms, or hot tubs. Infrared saunas are often preferred for frequent use because they operate at lower temperatures and are easier to tolerate.
So, How Often Should You Use an Infrared Sauna?
Most people benefit from using an infrared sauna several times per week, adjusting frequency based on comfort, recovery, and personal goals. Start slowly, stay hydrated, and pay attention to how your body responds.

When you begin comparing a swim spa vs. a hot tub for your backyard upgrade, it quickly becomes clear that both options offer meaningful benefits depending on how you plan to use your outdoor space. Each system brings a different type of relaxation, fitness value, installation requirement, and long-term cost structure. Choosing the right one depends on your lifestyle, your goals, and the environment you want to create at home. Below is a full breakdown to help you make a confident and informed decision.
Understanding the Basics: What Are Swim Spas and Hot Tubs
Swim spas are compact, self-contained aquatic machines designed to create a smooth, adjustable current that allows you to swim in place. They offer a hybrid experience by combining fitness-oriented water resistance with features similar to a spa. Hot tubs, on the other hand, focus primarily on hydrotherapy, comfort, and relaxation. They are equipped with massaging jets, ergonomic seating, and temperature controls that allow you to soak in warm water for pain relief and stress reduction.
Size Requirements and Space Considerations
One of the most significant factors in choosing between the two systems is the space available in your backyard. Swim spas are larger and longer than standard hot tubs because they require enough room for swimming or resistance training. They typically range from 12 to 20 feet in length. Hot tubs are compact and usually seat between two and eight people, depending on the model. They can be installed in a smaller footprint, making them ideal for patios, decks, and modest outdoor areas. While both swim spas and hot tubs require a stable, level foundation, hot tubs are easier to position because many models offer flexible installation options. Swim spas may require more planning to ensure there is adequate clearance for the shell, the mechanical components, and entry and exit points.
Wellness and Therapeutic Benefits
If wellness and therapy are high on your priority list, both systems can provide outstanding benefits, but they function differently. Swim spas support a wide range of fitness activities. The adjustable current allows for low-impact swimming, jogging, rowing, and resistance training. This makes them excellent for people recovering from injuries, athletes seeking targeted conditioning, or homeowners who want a versatile exercise environment. Many swim spas also feature seating with jets for post-workout relaxation. Hot tubs excel at hydrotherapy. Their purpose-built jet systems target sore muscles, joint pain, and tension. Warm water immersion supports circulation and reduces inflammation. This can be especially helpful for those with arthritis, chronic pain, or high stress levels. While swim spas can provide therapeutic options, hot tubs are specifically engineered for long-duration comfort and strategic muscle relief.
Ease of Use and Daily Convenience
Hot tubs offer immediate convenience. They heat quickly, maintain temperature efficiently, and are ready for spontaneous use after a long day. Modern hot tubs include intuitive controls, LED lighting, and ergonomic seat placement designed for effortless relaxation. Swim spas are also convenient, but because they are larger and involve exercise functionality, they require more planning for daily use. The water volume is greater, which means heating and maintaining the temperature may take longer. However, once they reach the programmed settings, they can be used for both workouts and relaxation in one place.
Maintenance Requirements
Maintenance is an important consideration with any aquatic system. Swim spas hold more water, which means more chemicals, more filtration, and more frequent monitoring. However, many modern swim spas include advanced purification systems that simplify routine care. Hot tubs have smaller water volumes and generally require fewer chemicals and less upkeep. With Jacuzzi® models in particular, built-in filtration and modern water care technology help keep the water cleaner and fresher with minimal effort. Although both systems need consistent attention, hot tubs tend to be easier to maintain on a weekly basis.
Installation and Setup Costs
Installation costs vary based on the model, site preparation, and electrical requirements. Swim spas are typically more expensive to purchase and install because of their size and complexity. They may require reinforced foundations, dedicated electrical hookups, and additional delivery considerations based on access. Hot tubs are more cost-effective to install. Many models plug into standard power or require only minor electrical upgrades. Because they are lighter and smaller, delivery is simpler, and your space may require less structural preparation.
Long-Term Operating Costs
When considering long-term expenses, energy use, maintenance materials, and repair potential all come into play. Swim spas consume more energy due to their larger pumps, heaters, and water volume. Though energy-efficient models and insulated shells help reduce costs, they remain more expensive to operate than a standard hot tub. Hot tubs are more energy efficient overall. Their smaller size and thermal retention systems make them less costly to heat and operate throughout the year. Over time, a hot tub generally represents a lower financial commitment compared to a swim spa.
Lifestyle and Entertainment Value
For many homeowners, the decision goes beyond features and cost. It often depends on the type of experience they want in their backyard. Swim spas offer a fitness-focused lifestyle. They are ideal for individuals who enjoy swimming, aquatic resistance training, or multi-use wellness environments. Families may also appreciate the versatility because children can use the swim area to play while adults enjoy the spa seating. Hot tubs are perfect for relaxation, conversation, and connection. They create an atmosphere centered on comfort and stress relief. Whether for romantic evenings, family time, or social gatherings, a hot tub provides an inviting focal point for your backyard.
Seasonal and Climate Considerations
In climates with varying seasons, such as the Roaring Fork Valley, both swim spas and hot tubs can be used year-round if properly insulated. However, hot tubs are particularly well-suited for cold weather. Their warm water immersion is soothing in the winter months, and the smaller water volume heats quickly even on cold days. Swim spas can also be used in cold weather, but they may take longer to heat and maintain ideal temperatures. Ensuring the system is well insulated and protected from the elements will help maintain performance throughout the year.
Property Aesthetics and Backyard Design
When designing an outdoor retreat, aesthetics matter. Hot tubs offer design flexibility and can be seamlessly integrated into patios, decks, or landscaped areas, providing a seamless addition to your outdoor space. Their compact footprint makes them adaptable to a wide variety of backyard styles. Swim spas require more space, but they provide a sleek, modern look that complements contemporary landscapes. Their long rectangular shape creates a visual focal point and can serve as a centerpiece for a fitness-oriented outdoor environment. Whether you prefer streamlined simplicity or a dedicated exercise hub, both systems can elevate your property.
Who Should Choose a Swim Spa
A swim spa is likely the best choice if you:
Want a dual-purpose system for fitness and relaxation
Enjoy swimming and resistance-based workouts
Need low-impact exercise options for rehabilitation
Prefer a single machine that offers both spa seating and a swim current
Have the backyard space to accommodate a larger structure
Want year-round aquatic fitness without building a full-sized pool
Who Should Choose a Hot Tub
A hot tub may be a better fit if you:
Prioritize relaxation and hydrotherapy
Want a cost-effective installation with lower operating expenses
Have limited backyard space
Prefer a simpler system with easy maintenance
Enjoy gathering with family and friends in a cozy, intimate setting
Want a warm, soothing escape after outdoor adventure or daily stress
Choosing the Best Fit for Your Home
Deciding between a swim spa and a hot tub comes down to your goals, your space, and the experiences you want to create. Swim spas excel in fitness, versatility, and multifunctional use. Hot tubs shine in comfort, hydrotherapy, and stress-free enjoyment. Both can be excellent additions to your home, but the right choice aligns with your personal lifestyle and how you envision using your outdoor space over time. If your priority is targeted exercise, year-round swimming, or full body conditioning, a swim spa may offer the perfect blend of performance and convenience. If your focus is warmth, relaxation, and social connection, a Jacuzzi® hot tub provides all the comfort and luxury needed to unwind anytime.
