A Wisconsin Sauna Builder Just Published Its Prices. It Says Most Builders Won’t.

Ask a Wisconsin sauna builder what a custom sauna costs and you will usually get a contact form. Wisauna, which builds by hand in the Chippewa Valley countryside south of Eau Claire, decided to just answer the question. As of August 1, its site put the starting price at $12,000 and the average commission around $24,000, and it listed a finished 8-by-8 cedar room at $18,000.

The company puts the reasoning plainly in its own price explainer: “Most builders make you call to find out. We’d rather just tell you.” And it goes further than a number, listing what actually moves it, which is windows, wood species, benches, finishes, lighting, and the stove.

That is a small thing that is not a small thing. In a trade where the standard answer is “every project is different,” a published starting price and a published average is a competitive position. By Wisauna’s account, most builders in North America’s backyard sauna market still make buyers call.

What the number actually buys

The interesting part of Wisauna’s pitch is not the price, it is the wall behind it. The company builds framed and insulated rooms carrying R-13 to R-21 Rockwool behind a continuous, sealed aluminum-foil vapor barrier, and it argues directly against the alternative most buyers are shown: kits built from thin uninsulated tongue-and-groove, which Wisauna puts at roughly R-3 to R-5.

That is the company’s own comparison rather than an independent test, and the honest caveat is that kit construction varies. But the direction of the argument is not controversial, and it is the right argument to be having. An uninsulated cabin is not merely slower to heat. It costs more every session, forever, and the gap compounds across a fifteen-year ownership window in a state where the heating season is long. A builder willing to put an R-value in writing is a builder who expects to be checked.

The rest of the spec is conventional in the best sense. Harvia stoves, the Finnish standard. Thermally modified spruce on benches and walls, which is chosen for dimensional stability and even color rather than for looks alone. Cedar doors and floors. LP SmartSide outside, and on some builds a professionally installed rubber roof with no seams in it at all, which is a choice made by somebody who has watched what Wisconsin snowmelt does to a flat detail.

Six builds and a trailer

The catalog is small on purpose. The Tidwell is the signature backyard room: an 8-by-8 hot box with a two-foot integrated porch for wood storage, thermally treated spruce benches and walls, a cedar door and floor, and a Harvia wood stove set against three large windows. The Lakeside runs 8-by-8 or 8-by-10 under a shed roof, wood-fired or electric. The Hearth is the compact one, two to four bathers. The Sun Setter is built around a panoramic hot box and a covered porch.

The Traveler is the one worth watching commercially. It is an 18-foot mobile build on a trailer: a 12-foot aspen-lined hot box, a Harvia wood stove, a six-foot entry that comes either as an open cool-down porch or a fully enclosed changing room, Rockwool insulation, and LP SmartSide armor for highway miles. Wisauna says it is the same build as the rental sauna arriving in October 2026, and that customers can buy the identical unit.

Building your rental fleet and your retail product on one spec is a sound move for a shop this size. The rental unit becomes a demonstrator that earns while it demonstrates, and it solves the problem the company names itself: almost nobody buys a sauna sight unseen.

Wisauna is not waiting for October to fix that. Dalhoe told SaunaNews the company is putting display saunas in at Down to Earth Garden Center on Highway 93 in Eau Claire, and expects them standing within the next few weeks. That is the cheap version of a showroom, and for a shop this size it is the right one: no lease, no staffing, and a stream of homeowners who are already in the building to spend money on the yard. Until now, the only way to stand inside one was to catch a pop-up event.

Why the salvage stays out of the hot room

Wisauna and No Boundaries Tiny Homes are separate companies, which is easy to miss. Both operate out of Eau Claire, both sell saunas, and Dalhoe, who answered for Wisauna, is named as an owner of No Boundaries on that company’s about page. Two businesses, one shared figure.

They also build out of different material. No Boundaries makes tiny homes, bungalows, and portable structures, and it made its name on architectural salvage, harvesting from deconstructed buildings so the material stays out of a landfill. Its sauna page describes rooms built from reclaimed stock with new cedar inside. Wisauna is specified in thermally modified spruce, Rockwool, a sealed vapor barrier, and engineered siding.

Asked whether that was a deliberate difference in approach, Dalhoe gave the short version: you can’t use old lumber and finished lumber in saunas. That is a materials rule, not a philosophy, and it is the same reason sauna interiors are left bare in the first place. Coatings and adhesives do not belong in a room running at 180°F with people breathing in it, and a reclaimed board arrives carrying a finish history nobody can fully account for. Thermal modification runs the other way: the sugars and moisture are cooked out before the board is ever installed, so it holds still through a cycle from a Wisconsin January to bench temperature twice a week.

No Boundaries says its sauna interiors are finished in new cedar, per its sauna page; the reclaimed material goes into the structure.

SaunaNews contacted Wisauna on August 1 with questions about the relationship between the two brands, its retail expansion plans, and the shift in materials. Chad Dalhoe answered for the company on August 5, and this piece includes his responses. Pricing, specifications, and model details are quoted from Wisauna’s own published pages as of August 1, 2026.
