Used Sauna vs. New Sauna: Which One Should You Choose?
A sauna is an incredible investment in relaxation, detoxification, and overall well-being.
But when it comes to buying one, should you go for a brand-new model or save money with a used one?
The wrong choice could mean hidden costs, repairs, or even safety risks. In this guide, we’ll break down the pros and cons to help you decide wisely.
Why Invest in a Sauna?
Investing in a sauna is one of the best ways to improve your overall well-being. Regular sauna use helps your body flush out toxins, improves circulation, and supports heart health.
Dr. Joy Hussain, an integrative medicine doctor, points out that stress reduction is the number one reason people worldwide use saunas, highlighting their powerful role in building mental and physical resilience.
Dr. Steven Gundry, a cardiologist, medical researcher, and author, explains that infrared saunas, in particular, help improve mitochondrial function, which plays a key role in energy production and longevity.
Studies have shown that frequent sauna bathing can have significant long-term health benefits.
"The more often you use the sauna, the stronger the health benefits," says Dr. Rhonda Patrick, a scientist and health educator.
"People who sauna four to seven times a week are 63% less likely to die from sudden cardiac death than those who only go once a week."
Where to Buy a High-Quality Used Sauna?
If you're looking for a high-quality used sauna, you have several great options. Many online marketplaces, like eBay and Facebook Marketplace, offer a wide selection, but always check seller reviews and ask for detailed pictures.
Some sauna manufacturers sell refurbished or demo models, which can be a safer choice with warranties.
Retailers specializing in saunas may also have pre-owned units in excellent condition.
Physical stores and wellness centers sometimes sell their older saunas when upgrading, making them another solid option.
While buying from an individual seller might be cheaper, a sauna retailer often ensures better quality and reliability.
Cost Comparison: Used vs. New Saunas
Buying a sauna is a big decision, and cost plays a huge role. The sauna and spa market has been growing rapidly, increasing from $3.97 billion in 2024 to $4.22 billion in 2025 at a 6.2% annual growth rate.
This surge shows that more people are investing in saunas for their health and well-being.
A new sauna can range from $2,000 to over $10,000, while a used one often costs 30–50% less.
That sounds like a great deal, but hidden costs can add up. Older saunas may need repairs, new heaters, or upgraded wiring, increasing expenses.
Installation costs also vary—some used saunas require modifications that new ones don’t.
Running costs matter too. Older models can use more electricity, making new energy-efficient options a smarter long-term investment.
While a used sauna saves money upfront, a new one might be cheaper over time.
Performance and Efficiency Differences
A new sauna usually performs better than a used one because it heats up faster and runs more efficiently.
Over time, used saunas may lose efficiency due to wear on the heater, insulation, or other components.
However, a well-maintained sauna can still deliver great heat and relaxation, making it a solid option for those looking to save money.
While new saunas are designed to be more energy-efficient, upgrading parts like the heater or insulation in a used sauna can improve performance.
Infrared saunas can definitely be much more comfortable for people while delivering the same sort of benefits," says Dr. Melissa Young, a Certified Functional Medicine specialist.
Maintaining overall wellness isn’t just about one habit—it’s about balance. Regular sauna use, combined with proper sleep, nutrition, and stress management, helps maximize long-term health benefits.
Maintenance and Upkeep Considerations
A used sauna needs more frequent maintenance than a new one because its components have already seen wear.
Common issues include heater inefficiency, wood deterioration, and electrical problems.
Before buying a used sauna, check for cracks, mold, and faulty wiring to avoid costly repairs.
Over time, repair costs add up, making a new sauna a better long-term investment. To keep an older sauna in good shape, reseal and re-stain the wood regularly.
Unlike used saunas, new ones often come with warranties that cover maintenance, reducing unexpected expenses. A new sauna means less hassle, while a used one requires extra care.
Health and Hygiene Concerns
A used sauna can collect bacteria and mold over time, especially if it wasn’t properly maintained.
To check for mold and mildew, inspect corners, benches, and ventilation areas for dark spots or musty smells.
If you find any, deep cleaning is a must. Scrub the surfaces with a sauna-safe disinfectant and let everything dry completely.
Poor maintenance can also lead to hygiene issues like sweat stains and lingering odors.
In some cases, unclean saunas may cause skin infections. Dr. Sara Gottfried, a board-certified gynecologist and author, points out that sweating plays a key role in detoxification, helping the body eliminate toxins through the skin.
A properly maintained sauna enhances this process, making it not only a relaxing experience but also a crucial part of overall health.
Compared to used ones, new saunas are much easier to keep clean since you control their upkeep from the start.
Durability and Lifespan of Saunas
A well-built sauna can last 15 to 30 years, but its lifespan depends on the materials used, how often it’s maintained, and the environment it’s in.
High-quality wood, like cedar or hemlock, resists warping and extends durability, while cheaper materials wear out faster.
Finland, known for its deep sauna culture, has around 3.3 million saunas for a population of 5.5 million.
That’s more saunas than cars, proving how essential and long-lasting they are in daily life.
A properly maintained sauna isn’t just a short-term investment—it can provide decades of relaxation and health benefits.
Regular maintenance, like cleaning, sealing, and checking for damage, keeps a sauna in top shape.
Used saunas naturally have a shorter lifespan, especially if they weren’t well cared for.
Signs of deterioration include cracks in the wood, rusted heaters, and poor heat retention.
Investing in proper care ensures a sauna stays functional and enjoyable for decades.
Warranty and Support Differences
When buying a sauna, warranty and support make a big difference. New saunas come with solid warranties, often covering several years, while used ones may have little or no coverage left.
Some manufacturers allow warranty transfers, but many don’t, so checking the policy is important.
Refurbished saunas sometimes include limited warranties, but they’re usually shorter than new ones.
Customer support is another key factor—new sauna owners get direct help from manufacturers, while used sauna buyers might struggle to find assistance.
Finding replacement parts is easier for newer models, and once a sauna is out of warranty, technical support can be costly or unavailable.
Installation and Setup Challenges
Installing a sauna comes with challenges, but a used one often requires more effort than a new one.
A new sauna arrives with clear instructions and all parts intact, making setup smoother.
In contrast, a used sauna may have missing or worn-out components, requiring extra time to find replacements.
Electrical connections can also be tricky, as older wiring might need upgrades to meet safety standards.
Missing parts can delay installation, and troubleshooting can be frustrating. Overall, setting up a used sauna usually takes longer, while a new sauna offers a hassle-free experience with fewer unexpected issues.
Energy Efficiency and Power Consumption
A new sauna uses less power than a used one because modern models come with better insulation and energy-saving technology.
Older saunas often consume more electricity due to worn-out heating elements and outdated designs.
The insulation quality also plays a huge role—poor insulation forces the heater to work harder, increasing energy use.
Newer saunas also have smart features like programmable timers and improved heating systems that reduce power consumption.
These advancements make modern saunas the better choice for energy efficiency.
Customization and Smart Features
New saunas offer endless customization, from wood type and lighting to seating layouts and control panels.
You can choose smart features like voice commands, programmable sessions, and temperature zoning for a personalized experience.
But what if you have a used sauna? You can still upgrade it with smart controls, adding Wi-Fi connectivity for remote access through a mobile app.
Features like Bluetooth speakers, chromotherapy lighting, and digital thermostats make every session more enjoyable.
Retrofitting a used sauna with modern technology is possible, but a new sauna gives you more built-in options. Smart features transform any sauna into a high-tech relaxation space.
Resale Value and Depreciation of Saunas
A sauna’s resale value depends on many factors, but some hold their worth better than others.
High-quality wood, like cedar or hemlock, keeps a sauna valuable longer, while cheaper materials wear down faster.
Popular brands also hold their value better because buyers trust them. Regular maintenance slows depreciation, but heavy use and neglect make a sauna lose value quickly.
Upgrading features, like better heaters or smart controls, can boost resale price, but only if buyers see the value.
Infrared and well-built traditional saunas tend to resell best. Choosing wisely means a sauna that stays valuable for years.
Factors to Consider Before Buying a Used Sauna
Check the Overall Condition
Look for damage, wear, and any needed repairs.
Before buying a used sauna, inspect it carefully. Look for any visible signs of wear, such as cracks, scratches, or broken parts.
Ensure the wood isn’t rotting, and check for mold or mildew, as moisture damage can ruin the sauna’s structure.
Test the heating element—does it warm up quickly and evenly? If the sauna has glass panels, make sure they are free from cracks.
A thorough inspection will help you determine if the sauna is in good condition or if it will require costly repairs.
Choose the Right Sauna Type
Decide between traditional, infrared, or steam saunas.
Saunas come in different types, including traditional, infrared, electric, and wood-burning models.
Traditional saunas use heated rocks and steam, while infrared saunas emit radiant heat. Wood-burning saunas provide a rustic experience but need more maintenance.
Consider where you plan to install it—indoors or outdoors? Portable saunas are another option if space is limited.
Think about your usage needs. A home sauna may have different requirements than a commercial one.
Understanding the pros and cons of each type will help you choose the best one.
Inspect the Heating System
Make sure the heater works efficiently.
The heating system is the heart of any sauna. Check what type of heater it has—electric, wood-burning, or infrared.
Look for signs of wear, rust, or damage on the heating elements. Does the sauna heat up efficiently?
A faulty heater may struggle to maintain the right temperature, leading to higher energy costs.
Ask if the heater has ever been replaced or repaired. Also, test the controls to make sure they function properly.
A sauna with a reliable heating system will provide a better experience and save you from future repair costs.
Know the Power Requirements
Ensure your home can handle the sauna’s power needs.
Used saunas may have different electrical needs. Check whether it runs on 110V or 220V and whether your home can support its power requirements.
Some models need a dedicated circuit, while others can plug into a standard outlet. Verify how many amps it draws and whether it requires hardwiring.
Also, ensure that the sauna includes a compatible power cord. Knowing these details beforehand prevents surprises when setting up your sauna and ensures safe operation.
Measure the Size & Capacity
Confirm it fits your space and suits your needs.
Before purchasing a used sauna, measure the available space in your home. Consider both exterior and interior dimensions.
How many people will use it at once? A one-person sauna takes up less space, while a four-person sauna requires more room.
Make sure it fits comfortably in your desired location, whether it's a basement, bathroom, or outdoor patio.
Check the internal seating arrangement to ensure enough space to sit or lie down comfortably. Proper sizing ensures a relaxing experience without crowding.
Evaluate Airflow & Insulation
Good ventilation and insulation improve efficiency.
A sauna should retain heat efficiently while allowing fresh air circulation. Check for ventilation openings and make sure they’re not blocked.
Poor airflow can cause overheating and discomfort. Inspect insulation, especially in the ceiling, to ensure heat retention.
Look for gaps or cracks that might lead to heat loss. A well-insulated sauna will maintain a consistent temperature and reduce energy waste. If the sauna cools down too quickly, it may need better insulation or sealing.
Review Past Use & Maintenance
A well-maintained sauna lasts longer.
Find out how often the previous owner used and maintained the sauna. A sauna that was used lightly and cleaned regularly is a better buy than one that was neglected.
Ask if it was ever left unused for long periods, as inactivity can lead to mold, electrical problems, or wood damage.
Look for any signs of water damage or mildew, as these can cause structural issues. If possible, have an electrician inspect the wiring to ensure safety. Proper maintenance history can indicate the sauna’s longevity.
Check for Replacement Parts
Ensure parts are available if needed.
Before buying, research whether replacement parts are available. Some older sauna models have discontinued parts, making repairs difficult.
Can you use generic parts if originals aren’t available? Find out if the wood panels, heaters, or controls can be replaced if needed.
If the sauna has unique features, check whether they are still supported by the manufacturer.
Knowing these details helps you avoid the frustration of owning a sauna that’s hard to repair.
Compare Cost vs. Buying New
Weigh savings against potential repairs.
Used saunas are generally cheaper than new ones, but the cost savings depend on their condition.
A well-maintained used sauna can save you a lot, while one that needs frequent repairs may end up costing more.
Compare maintenance and energy costs between used and new models. Older saunas might use more electricity, making them less efficient.
Consider refurbished saunas as well—they often come at a lower price but with upgraded components.
Weighing the upfront cost against long-term expenses will help you make the best decision.
Assess Seller Trustworthiness
Buy from a reputable source.
Finally, make sure you're buying from a reliable seller. Check online reviews or ratings if purchasing from a marketplace.
Ask for proof of purchase or ownership to ensure it’s not stolen. A trustworthy seller should be upfront about any defects or past repairs.
Whenever possible, inspect the sauna in person before committing. Be cautious if the seller demands a rushed payment or refuses to meet in person.
A transparent transaction will help you avoid scams and ensure a better buying experience.
Final Verdict: Should You Buy a Used or New Sauna?
When it comes to investing in your relaxation and well-being, which sauna suits you best, a brand-new model or a pre-owned option?
Both choices offer significant benefits, from stress relief to improved circulation, but the right one depends on your priorities.
If long-term reliability, energy efficiency, and hassle-free maintenance are key, a new sauna is a smart investment, offering warranties and modern features that enhance your experience.
On the other hand, if budget is your main concern and you are willing to inspect and maintain a unit, a high-quality used sauna can provide the same therapeutic benefits at a fraction of the cost.
Whatever your preference, the most important step is making an informed decision.
