We’re a one-stop-shop for high-quality saunas. We can get you any of the following:
We’re a company with deep Finnish roots—nearly every member of our team grew up with a sauna in the home and continues to use one today. John Raisanen’s father brought Finnleo to Cokato, Minnesota in the 1980s, and Sauna Supply Company is now located just down the road from the Sauna360 factory. We’re proud to be a partnered dealer of Finnleo.
Our connection to sauna runs deep. To us, it’s more than heat and steam—it’s a place to gather, relax, and build lifelong bonds. Share a sauna with friends or family, and you’ll never forget the experience.

Our sauna showroom is always evolving, with new saunas, heaters, and products regularly added—but you can consistently expect to see 8 to 12 saunas on display. This includes a variety of custom indoor and outdoor saunas, modular kits, and infrared models.
We also feature a large selection of sauna heaters—both electric and wood-fired—on display and available for purchase.
To help you make the right choices, we offer a range of wood and door samples so you can see, touch, and compare the options that best match your vision.
We do carry saunas, material, heaters (electric and wood-fired), sauna doors, and other parts at all times. Custom saunas have a lead time, but once the project is started we finish it within a couple of days.
Depending on scarcity our stock models vary throughout the year. Call us at 612.505.9700 to see if your desired sauna is in stock.
Yes! All sauna heaters that are UL listed (in the United States) are designed so that you can throw water on them. This includes traditional indoor and outdoor saunas.
The electrical you’ll need will depend on the size of the heater/ sauna that you have. Always check the sauna heater installation manual to ensure the correct wiring will be connected to the heater.
The smallest traditional saunas (4’x4′ Hallmark Series) we offer use 1.7kW or 2.3kW heaters and can use 120 volt – 15AMP or 120 volt – 20AMP (dedicated) outlets respectively. Any traditional electric sauna with a 6kW heater or larger require 30-45AMPs – 24o volt power (AMPs depend on the size of the heater).
Our Finnleo Infrared S-Series Saunas will can be plugged into a standard 120 volt – 15AMP outlet or 120 volt – 20AMP outlet depending on the model. Learn more about the S-Series Infrared Saunas here.
Our modular Finnleo InfraSaunas (hybrid) will use either standard 120 volt- 15AMP, 120 volt – 20AMP dedicated, or 30 AMP – 240 volt power depending on the model.
Custom saunas (traditional, infrared and hybrid) require 30-45 AMP – 240 volt power.
Being from Minnesota and knowing the cold temperatures we will see through January and February, yes, all of our outdoor saunas are built and insulated to perform in and withstand Minnesota winters. This includes our custom outdoor saunas, Euro Series, Auroom Series, and Northstar Series.
Yes! We built a custom traditional cedar sauna in our showroom so that you could come and try it! It’s in a room with a shower so that you can clean off after you’re done.
If you’re looking for an infrared sauna, we one those that can be tested too!
If you want to get the full sauna experience to feel the bliss that comes with taking a sauna, stop on in. Give us a call (612.505.9700) or send us a message through our contact page before so we can warm a sauna for you.
Yes. In some cases, it’s actually possible to have both a wood fired heater and an electric sauna heater in the same sauna.
You have to have a space to put your custom sauna. In most cases you’ll need to wire in 240 volt power (if you’re putting in an electric sauna). From there, we can help you turn any room into a sauna no matter whether you already have the sauna space framed in, are taking down drywall in a current room, or are starting completely from scratch.
If you are building an outdoor sauna, you’ll need a flat surface to put the sauna on. Ideally the sauna has a concrete pad, or pavers to sit on.

A modular sauna comes pre-fabricated in panels to form a free-standing sauna. Each of the panels, or sections, connect together.
A modular sauna is a great way to put a sauna up quickly and gives you the option to take it with you when you move.
Traditional saunas typically range from 160°F to 194°F, while infrared saunas operate at 120°F to 150°F. Wood-fired traditional saunas can get even hotter than 194°F.
The ideal range depends on the person and what you’re looking for in a sauna. Some people like a softer sauna with higher humidity (160°-180°), where others prefer a hot and dry sauna (180°+). Experiment to see what works best for you.
Depending on the heater you put in your sauna you can control the humidity for a softer sauna experience. The Finnleo Himalaya is one of the heaters you can do this with.
A typical traditional sauna session lasts 15 to 30 minutes (per round) and infrared sauna sessions typically last 20 to 45 minutes. However, it’s best to listen to your body and stay hydrated. Read our full guide on it here.
For general health benefits, 3-4 times per week is recommended, but some people (like us) enjoy using them daily.

Saunas promote detoxification, improved circulation, muscle recovery, stress relief, better skin health, and enhanced cardiovascular function.
Health benefits aside, they feel amazing to bathe in!
The exterior of an outdoor sauna should be stained, sealed or painted to protect against the elements.
Like all saunas, you will have to replace the rocks in the heater eventually (the constant heating and cooling causes the rocks to break down) and wipe the benches/ backrests. Saunas are generally low-maintenance.
Traditional saunas generally do not require a drain unless you plan to pour water over the benches or floor regularly.
That said, a drain can be nice to have in the sauna. You may have to occasionally wipe the floor down in the sauna with a towel if you don’t have a drain.
Cedar deck board floors, tile with anti-slip properties, or concrete work well for saunas. Avoid carpets or absorbent materials.
Floors with vinyl false tops are popular in our saunas.
Cedar deck boards are commonly used in our outdoor saunas, especially when installed near a lake or a swimming pool where you plan to sauna-swim. Deck boards will do a better job of letting water through the cracks than a vinyl false floor.
Most electric saunas reach optimal temperature in 40-60 minutes, while wood-burning saunas may take 45-75 minutes. Factors affecting heating time include sauna size, heater power, insulation quality, and starting ambient temperature. Pre-heat your sauna before use for the best experience.
A properly installed sauna with adequate vapor barriers and ventilation should not cause moisture problems. Ensure your sauna has proper insulation, a vapor barrier on the warm side of the walls, and adequate ventilation. Keep the door slightly open after use to allow moisture to escape, and run the heater for 10-15 minutes post-session to dry the interior.
Both! Shower before to remove lotions, deodorants, and dirt that can clog pores and affect the wood. A quick rinse is sufficient. After your session, take a cool or warm shower to rinse away sweat and help your body temperature normalize.
Traditionally, saunas are used nude or with a towel wrap. If you prefer coverage, wear a bathing suit or loose, breathable cotton clothing. Avoid synthetic materials that can become uncomfortably hot. Sit on a clean towel to protect the wood and maintain hygiene.
No, electronic devices can be damaged by high heat and humidity. The extreme temperatures can cause permanent damage to batteries and components. Leave electronics outside and enjoy the digital detox that sauna time provides.
Daily: Air out after use by leaving the door open Weekly: Wipe benches with a damp cloth Monthly: Clean the floor Annually: Deep clean all surfaces with mild sauna-specific cleaner, inspect sauna stones and replace broken or cracked stones, and have heater inspected by a licensed electrician. We have a comprehensive guide on sauna maintenance here.
Hydration is crucial. Drink 16-20 oz of water before your session. While some enjoy water during longer sessions, it’s generally better to hydrate between rounds. After your session, replenish with water or electrolyte drinks. Avoid alcohol before and during sauna use.
You can add a few drops of sauna-safe essential oils (eucalyptus, birch, pine) to your water bucket before ladling onto stones. Never pour oils directly onto the heater. Use sparingly – a little goes a long way in the heated environment.
Inspect stones annually. Replace them if they’re crumbling, have deep cracks, or have shrunk significantly. Good stones should last 2-5 years with regular use. Poor quality or deteriorating stones can affect heat distribution and may release dust.
