Our custom indoor saunas are constructed using only the highest quality building materials, in true Nordic fashion. They’re not just designed to look at, they’re built to be used daily for a lifetime.
Putting a custom sauna in your home should be as stress free as you’ll be after relaxing in it.
From the initial design of your sauna, to the first steam you take, we take a tremendous amount of pride in the level of service we offer.
Our saunas come with a 5 year warranty and are built to the highest in sauna construction standards, using only the finest materials and heaters available.
The indoor sauna customization process is simple. You decide how you want the sauna to look and feel (we’re happy to help with design if you want, but we’re also happy to sit back and run with your vision ) and we’ll build it.
Our saunas are built using only the highest quality materials, for form and function. From Clear Western Red Cedar, Nordic Spruce, or Clear Canadien Hemlock, your sauna space will hold up to even the most hard-core of sauna use for decades to come.
All wood in a custom cut kit is cut and pre-built to your exact dimensions.
All Custom Cuts kits include everything you need to complete the interior of your sauna space beyond framing and insulation. That includes foil vapor barrier, T&G, pre-built upper and lower benching, backrest, heater guard, headrest(s), vent grills, sliding vent valve, duckboard flooring for walk area, bucket & ladle, corner & ceiling trim, interior door casing, and hardware package.
You do not need to take everything listed in the kit! Pick and choose the pieces you need.
There are nearly endless size and layout options for a custom indoor sauna.
There are several factors to consider when deciding on sauna room size and layout. If you have no idea where to begin, please call us! (remember, we do this for a living)
You can start by browsing through several “standard” CAD layouts shown here, and adjust however fits your space.
The sauna heater is the heartbeat of the sauna, the most critical factor for the best sauna experience.
After you have decided on the size and layout of the sauna, we find the appropriately sized heater for it. Each heater will offer a different experience. Our residential Finnleo heaters comes with a five-year warranty and we stock all of the most common heater parts you could need. Our American tech support team supports customers across North America every week of the year Monday through Friday.
The Himalaya Rock Tower is a premier heater. Because of its rock mass and Biowater Technique Tank, it creates a soft heat for a better sauna.
The Designer Series is a reliable, sturdy sauna heater. It is built to withstand heavy use and heats up quickly because of its smaller rock mass.
The Laava and Magma are reliable, durable, commercial grade sauna heaters. Built to warm even the biggest of sauna rooms.
Each wood type offers a different feel.
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 (No knots – they get hot in the sauna heat!)

Standard Window Sizes:
Sauna lighting is critical for the ambiance of the sauna. Too much or too little lighting will affect the experience.
There are multiple different options for sauna lighting. The most common is the RGBW Strip Lighting, but it’s not the only option.
The RGBW LED strip lighting and the RGBW LED puck lights are compatible with the SaunaLogic 2.0 Control. Change the light color and brightness to suit your liking. The lights can be purchased and set up a la carte too.
LED strip lighting comes pre-installed behind your backrest. Can also be placed under bench.
Puck Lights go into the ceiling.
Mounts on the wall.
A duckboard adds character to a sauna room.
A duckboard walkway comes standard in most of our custom sauna kits. A duckboard is nice to walk on and looks good in the sauna, but it’s not a requirement to have one.
An additional duckboard can be purchased for outside of the sauna (entryway, etc).
Bench Skirts & Bullnose Bench Trim are popular upgrades for their elegant look.
Bench skirts are commonplace in a sauna for the look and feel they offer.
