Transform any space into your personal infrared sauna with the world’s safest, most advanced infrared technology—built to your exact specifications.
Custom infrared saunas aren’t those pre-fab boxes you see online. These are permanent wellness installations we build specifically for your space using Finnleo’s Pure Infra panels—infrared technology that beats Sweden’s radiation standards (toughest on the planet).
Whether you’re converting that awkward basement corner or framing up a new space, you get to choose everything: the size, the wood, the bench layout, and more.
The result? Therapeutic heat that penetrates deep into muscles and joints that detoxes and rejuvinates. No more sharing with strangers. Just pure, healing heat whenever you need it.
Slanted ceiling? Converting an old closet? We’ve built saunas in spaces you wouldn’t imagine a sauna could go. Every design is CAD-planned to maximize your exact area.
5-year coverage on all Finnleo components
Not some sketchy online warranty you’ll never collect on. We’re right here in Cokato, not in a warehouse overseas. When you need service (rare, but it happens), we actually show up.
EMF levels below 1 milligauss (Swedish standard: 2.0)
Third-party tested by Intertek—the radiation levels inside are actually lower than in your living room. We’re talking measurable science, not marketing claims. Your health is why you’re buying a sauna; we make sure it stays that way.
Start your sauna from bed, the office or the grocery store. Adjust temperature from the couch. Set custom programs for each family member. Check if someone left it on. No subscription fees, no complicated programming—it just works.
Premium, sustainably-sourced options that last decades. Western Red Cedar for that incredible aroma, Nordic Spruce for authentic Finnish aesthetics, or Canadian Hemlock for clean, modern looks (and more options available).
When you choose a custom infrared sauna, the options are endless—wood types, layouts, and more. Design it yourself with our guidance, or enjoy a white-glove experience where we handle every detail for you.
We’ll craft it to match your exact vision—built around your needs and your style.
More than just dimensions, the size of your sauna defines its purpose. Are you seeking a private space for solo meditation, or a social hub for family and friends? We’ll help you match the footprint to your lifestyle. Note: infrared saunas are limited in size because the effectiveness of the infrared panels decreases when the sauna is too large (~7’x8′)
All of our custom infrared saunas feature Finnleo Infrared Panels.
These infrared panels are low EMR/ EMF (less than 2 milligauss which surpasses the Swedish Institute Standard).
The sauna is controlled with the InfraLogic 2 Control. The sauna can be controlled remotely with the SaunaLogic App on your Iphone or Android.
Finnleo parts and components come with a five year warranty in residential saunas.
All our wood is mill-direct, using only the highest quality, hand-selected wood. All from verified sustainable forests. All wood choices are chosen for their ability to hold up for years (typically decades) in the harsh sauna environment.
All wood that touches skin (benches, backrests, duckboard flooring, heater guard, headrest) is chosen for staying cool to the touch of the skin (knots get hot in the sauna!)
Wood Types Available :
Benches in any infrared sauna are important, but particularly on ours.
We do not build infrared saunas that only feature infrared panels on the walls. A major component of our infrared saunas is in heating as much of the body as possible and one of the most effective ways we accomplish this is through incorporating infrared panels under the benches (calf area) of your infrared sauna room.
We offer 2 main types of lighting for your custom infrared sauna :
Puck Lights go into the ceiling.
Cariitti glass fiber lighting can be installed in the ceiling to create a halo effect.
Each sauna door swings out. The glass doors feature a single pane, tempered glass with a latch. Wood doors feature a single clear, tempered pane down the center, with ball & catch latch or self-closing hinges.
Door Types Available :
Our sauna doors are available in sizes :
Our standard sauna window comes in a single pane, tempered glass. We do offer double pane windows. They’re available in both clear and bronze tint. All windows pre-hung in the panels.
Below are our standard sauna window sizes in the custom sauna. We can do entirely custom window sizing if the below options are not what you’re looking for.

Our Finnleo Infrared Package Includes The typical custom infrared sauna comes with:
Simple Maintenance Requirements Here’s the truth: infrared saunas are nearly maintenance-free. Wipe benches monthly with a damp cloth. Clean the floor and glass when it needs it. No rocks to replace, no elements to burn out. Fifteen minutes monthly keeps it pristine.

Traditional saunas heat the air to 150–200°F, which in turn heats your body. Infrared saunas work differently—they warm you directly at 110–130°F using light waves, similar to feeling the sun on your skin on a winter day. Both make you sweat and help detoxify the body, but infrared penetrates deeper into the muscles.
In general, you’ll need to spend 30–45 minutes in an infrared sauna to feel the effects, compared to just 10–20 minutes in a traditional sauna.
With cheap imports? Absolutely. Our Finnleo panels measure under 0.8 milligauss. Your laptop emits 2-5 milligauss for comparison. We beat Sweden’s 2.0 milligauss standard (world’s toughest) by 60%. View the Intertek report if you want the full data.
Those online prices are tempting. Here’s what we’ve found about them: The “low-EMF” claims rarely check out (we’ve tested them at well over 20 milligauss) and good luck getting replacement parts from a dropshipper. When something goes wrong (and it likely will), you’re stuck troubleshooting through email with someone who’s never used a sauna.
We’re a short car ride away in Cokato. We answer your phone calls. We can get you replacement parts. The price difference isn’t markup—it’s the difference between a real sauna and an expensive disappointment.
Research shows infrared saunas can increase circulation, promote relaxation, and support muscle recovery after exercise. Some studies suggest regular use may help with temporary muscle and joint discomfort. While individual experiences vary greatly, the combination of heat therapy and relaxation is why many people incorporate infrared saunas into their wellness routines. Always consult your physician before beginning any heat therapy program, especially if you have health concerns.
Almost nothing. Wipe the benches monthly with a food-grade cleaner. Clean the floor and glass as needed. That’s it. No rocks to replace, no heater elements to burn out, no special chemicals. Arguably less maintenance than your coffee maker.
If you have other questions or need specific information, don’t hesitate to ask. We have years of sauna experience and will help you with what you need.
