Custom Outdoor Saunas, Designed Around Your Property

Drawn for your property, from a blank page.

A custom outdoor sauna starts with your property instead of a floor plan. Most of the saunas in our project list are one-off builds: two-room layouts with a changing room, oversized porches, lake-facing window walls, a shed turned into a sauna, and two saunas on wheels.

Two-room saunas with a changing room

The most common reason to go custom is a second room laid out your way. In Ham Lake we built an 8x14 with a changing room ahead of the hot room and an IKI Mini Wood stove. In Monticello, an 8x16 wood-fired sauna has a dressing room and sits on a deck the owners extended for a cold plunge and an outdoor shower. In Longville, the dressing room opens onto an oversized porch for cooling off.

A changing room keeps snow and boots out of the hot room and gives you somewhere warm to sit between rounds. In a Minnesota winter it earns its space.

Built around a view

On a lake lot the window is the design. We have laid out saunas for the view of Clearwater Lake, the Mississippi River at Clear Lake, and Big Lake in Wisconsin, placing the benches first and the glass where the top bench looks.

Cladding and finish

Not every sauna should be black. The Becker build is clad in shou sugi ban, charred wood chosen for how long it lasts as much as how it looks. Others are sided to go with the house or cabin they sit beside. Inside, it is cedar on the walls, ceiling and benches.

Conversions, rebuilds and saunas on wheels

Some of our favorite jobs did not start from nothing. By Clearwater Lake we turned an old storage shed into a sauna with an IKI wood heater and a new cedar interior. Near Annandale we gutted an existing lakeside sauna and rebuilt it on the same footprint with new insulation, cedar, lighting and bigger windows.

We have also built two mobile saunas. One is an 8x16 for the north metro with cedar benches for up to 15 adults and a trap door in the dressing room floor for cold plunges on a frozen lake.

What moves the price: outdoor sauna pricing. How it gets to your yard: site work, delivery and installation.

Turnkey projects

From empty backyard to finished sauna.

We can take responsibility for the whole project, so you are not left coordinating several contractors. Depending on the job, we handle:

  • Sauna design
  • Floor-plan development
  • Material selections
  • Construction
  • Site preparation
  • Gravel pads
  • Concrete piers
  • Pavers and slabs
  • Electrical coordination
  • Electrical hookup
  • Delivery
  • Placement
  • On-site construction

How site work, delivery and on-site builds go

Jaden is great to work with, he was patient while we made our decisions and then constructed the sauna we asked for in just 3 weeks. He helped get the ground ready and helped us find an electrician. This was as close to turn key as it gets. We are 💯 satisfied and highly recommend.

From our customers

We couldn't be happier with our new custom sauna, changing room, and storage unit! Jaden is a professional well beyond his years, offering impeccable response time and customer service. He consistently kept us updated, stayed perfectly within budget, and actually beat the estimated timeline. His craftsmanship speaks for itself. The fact that his team came back on site to alter doors and fix a minor breaker switch perfectly highlights his commitment to putting customers first. We've already received so many compliments and just love our new gem by the water. Thank you Northern Steam!

When a custom build is the wrong call

  • If a standard size suits your yard, start with the Kota, Tuli or Superior. A proven layout costs less than a drawing from scratch, and all three can still be changed.
  • If you need it in a hurry, a custom design adds a design round before the build starts.
  • If you are after the lowest price for a hot room, a kit will be cheaper. We do not build kits, and we would rather say so up front.

FAQ

Custom sauna questions

What does a custom outdoor sauna cost?

Our fully custom outdoor saunas run from $35,000 to $65,000 and up. Size, the number of rooms, the window package, cladding, the heater and your site conditions drive the number. We send an itemized proposal after a site visit so you can see what each choice costs.

Can you add a changing room to a sauna?

Yes. Two-room layouts are the custom request we get most. We have built them in Ham Lake, Monticello, Longville and Dassel, with the changing or dressing room ahead of the hot room so boots, coats and snow stay out of the heat.

Can you convert a shed or rebuild an old sauna?

We have done both. By Clearwater Lake we converted an old storage shed into a wood-fired sauna, and near Annandale we gutted an existing lakeside sauna and rebuilt it on the same footprint. Whether it makes sense depends on the structure, so we look at it in person first.

Do you build mobile saunas?

Yes. We have built two saunas on wheels, including an 8x16 mobile sauna for the north metro with an IKI wood-fired stove and cedar benches for up to 15 adults. Tell us how you plan to use and tow it and we will design around that.
