Custom Sauna Builder in South Dakota
Every sauna we build starts in our Minnesota shop and ends up wherever you need it in South Dakota, from a backyard in Sioux Falls to a cabin in the Black Hills. We build the traditional way, a red cedar hot room heated by a wood fired stove, with an electric option available for outdoor builds where that makes more sense. Mobile on a trailer or set permanently on your property, each one is built to your specifications from the ground up.

Finnish Sauna Building, Brought to South Dakota
We are a Finnish rooted company based in the Twin Cities, and the way we build has not changed much from how our families built saunas back home. Wood fired heat, real cedar, no shortcuts on insulation or venting.
South Dakota covers a lot of ground, from farmland in the east to the Black Hills and Badlands in the west, and the people who reach out to us want a sauna for very different reasons. Some are looking for something to park at a lake place, others want a permanent fixture on ranch land or acreage where the nearest neighbor is miles away. Either way, the build starts the same, a proper hot room and a stove that can actually hold heat through a South Dakota winter, not just take the edge off.
How It Works?
Tell Us About Your Dream Sauna
Size, style, stove type, budget. We will put a plan together based on what you tell us and answer questions as they come up.
We Build It
Your sauna is built to your specifications in our Minnesota shop, using the same methods and materials that have defined Finnish sauna building for generations.
We Deliver It
Once it is ready, we bring it to you and set it up on site, anywhere in South Dakota.
Mobile or Permanent Outdoor Sauna
The stove and the cedar hot room are the same regardless of which one you pick. What actually separates them is whether the sauna stays fixed on your land or goes wherever you take it. Customers picking a permanent build usually have a specific spot already in mind, a backyard, a lake lot, a piece of family land. Customers picking mobile want the option to move it, to the cabin one weekend and back home the next.
Take Anywhere
Mobile Sauna
Built on a heavy duty trailer so you can bring it to the lake, the hunting land, or wherever else the weekend takes you. Same cedar interior and real stove as our permanent builds.

What people say about us
What You Can Customize
The hot room and stove type are the two decisions that shape everything else, cedar walls and either wood fired or electric heat. Once those are set, the rest comes down to how you plan to actually use the sauna day to day. If you host people regularly, a dressing room or covered porch gives everyone a place to cool off between rounds. If you want more light and less of a closed in feel, windows and sliding vents make a real difference. Mobile builds add one more choice on top of that, solar power if you want to use it somewhere without a hookup, or shore power if you will mostly be plugged in.
None of these are default upgrades tacked onto a base model, they are just the parts of the build that depend on how the sauna fits into your life rather than what it is made of.
Financing is available, and saunas can qualify as an FSA or HSA wellness expense. Details →
Service Areas
Where We Deliver in South Dakota
Free delivery and setup covers anywhere within 300 miles of the Twin Cities, which reaches the eastern part of the state comfortably, Sioux Falls, Brookings, Watertown, Mitchell, and out toward Aberdeen. West of that, toward Pierre, Rapid City, and the Black Hills, falls outside the free radius and a delivery fee applies. We still deliver out that way regularly, including to ranch land and property well off the highway. Send us your location and we will give you a clear number before you order.
Why Build Custom Instead of Buying a Kit
Most of what gets sold as an affordable backyard sauna is a prefab kit, flat pack panels shipped to your door for you to assemble yourself. It can work if a standard size happens to match your space and your budget is the deciding factor. But a kit is still a kit, built to a fixed layout with seams that eventually leak and insulation that was never meant to handle a real South Dakota winter.
A custom build starts from a different place entirely, your land, your layout, and how you actually plan to use it. Here is what that gets you in practice.
Built for Your Actual Space
No standard footprint to work around. We build to the dimensions and layout that fit where you are putting it, whether that is a tight backyard lot or open ranch land with room to spare.
Real Heat Retention
Framed and insulated like a proper structure rather than assembled from panels, so the wood fired stove keeps the hot room at temperature instead of fighting constant heat loss.
Add Ons That Match How You Use It
A dressing room, extra windows, an upgraded stove, solar power for a mobile build, whatever you actually need rather than whatever came standard in the box.
Built to Last Decades, Not Seasons
Solid construction and quality materials mean a custom sauna holds up through years of South Dakota weather, where a flat pack kit is often looking rough after just a handful.
None of this means a kit is a bad choice for everyone, if the standard size fits and budget is the priority, it can get the job done. But if you want a sauna that fits your land, holds heat the way a proper hot room should, and is still standing in twenty years, that is what a custom build gets you that a kit cannot.
Frequently Asked Question
How does a wood fired sauna hold up in a South Dakota winter?
Every build is insulated for cold weather use, and a wood fired stove brings the hot room up to temperature quickly even on the coldest nights, whether you are in Sioux Falls or up in the Black Hills.
Can you deliver to ranch land or a rural property?
Yes, a good number of our South Dakota deliveries go to ranch land, farms, and property off the main road. Tell us about the access, gravel roads, gates, distance from the highway, and we will plan the delivery around it.
Does a sauna make sense for a lake cabin I only use part of the year?
It does, especially as a mobile build. A trailer sauna can sit at the cabin all season and come home with you in the off season, or stay in place year round if you prefer not to move it each time.
Can I see the sauna before buying?
Yes. We have physical locations in Golden Valley, Cokato, and Brimson where you can come and see the sauna up close. You can also rent one first and apply your rental fees toward the final purchase price.
How much does a custom sauna cost?
As a reference, our standard 10 foot Essential Sauna starts at $14,900 and includes a red cedar steam room, wood-fired stove, benches, exterior siding, and a heavy duty trailer. Smaller and larger sizes are available, and add ons like a dressing room, extra windows, upgraded stoves, and solar or shore power shape the final price. Reach out and we’ll give you a clear number for the build you have in mind.
How long does it take to build a custom sauna?
Most builds are finished within about four weeks once the specifications are locked in. Timelines can shift slightly depending on materials and our schedule, and we will give you a realistic estimate before starting.
How do I choose a sauna builder?
Look for a custom sauna builder with genuine Finnish sauna experience, not just a company assembling prefab kits. Ask what materials go into the build, whether the stove is a real wood fired unit, how well the sauna is insulated for Wisconsin winters, and whether delivery and setup are included in the price. A good sauna builder should also be willing to walk you through sizing, layout, and add on options rather than offering just one fixed design.
How do I maintain my sauna after delivery?
A clear, level spot roughly 10 by 20 feet. We handle setup and walk you through the first fire before we leave.
