A Redwood Outdoors 4 person cabin sauna kit costs $5,399. You should budget at least $1,700 more for professional electrical hookup by a licensed electrician. Two people can assemble the sauna in half a day, but site prep and trenching add extra labor. Total project cost is around $7,099 before optional upgrades.

A Redwood Outdoors 4 person cabin sauna is a DIY kit made from Scandinavian Thermowood, featuring a Harvia electric heater and an interior bench, back rest, and footrest. The kit includes everything needed for assembly except the foundation and electrical work. Katherine Englishman installed a similar Redwood Outdoors Mini-Cube 2-Person Sauna in coastal Maine; that model measures 5.5 feet long, 4 feet wide, and 6.5 feet high.

What Does the Redwood Outdoors Mini-Cube Sauna Cost?

The base kit costs $5,399. When Katherine Englishman installed hers, the electric hookup added $1,700 to the total project cost. That brings the out-the-door investment to $7,099, not including optional upgrades.

Shipping is included in the kit price. The main structure arrives in a wooden crate via FedEx Freight, while the heater and rocks ship separately. Local building codes and electrician rates influence the final tab, but $1,700 is a realistic starting point for a straightforward hookup.

What’s Inside the Redwood Outdoors Mini-Cube Kit?

The kit arrives in a wooden crate via FedEx Freight. The Harvia electric heater and rocks ship separately. Inside the crate, you’ll find the front wall with glass door, the back wall, approximately 50 wooden staves (Scandinavian Thermowood), two stainless steel bands, an interior bench, back rest, footrest, a wooden front step, an interior LED light, a sauna thermometer and hygrometer, roof shingles, a sauna bucket and ladle, a door mat, and a felt sauna hat. All of these components come with the kit, so you don’t need to source any extras.

How to Prepare the Site for a Redwood Outdoors Mini-Cube Sauna

Katherine Englishman prepared her site using these steps. First, dig a 54-inch-long by 72-inch-wide area. Then bury four concrete deck footers in each corner of the base.

Build a wooden platform using pressure-treated lumber for the foundation. Fill the base open space with weed cover and pea gravel. This approach creates a stable, well-drained foundation that you can adjust to your yard’s conditions.

How to Assemble the Redwood Outdoors Mini-Cube Sauna

Two people can assemble the sauna kit in half a day. Katherine Englishman used a 4-foot, 2-foot, and 9-inch level, two cordless drills, a soft mallet, an adjustable socket wrench, and measuring tapes. She also built a metal roof over the sauna instead of using the provided shingles — a change that added time but created a more durable overhead cover for coastal Maine weather. The kit’s straightforward design avoids complicated joinery, so the work proceeds swiftly.

How Much Electrical Work Does a Mini-Cube Sauna Require?

After assembly, the electrical connection is the final major cost. You’ll need to trench a path for the cable. Katherine dug a 30-foot-long, one-foot-deep trench from the house to the sauna.

While you can handle the digging, a licensed electrician must wire the light and heater — the job took one full day. The electrician installed a disconnect switch on the house exterior for safety and connected the Harvia heater’s timer with its one- or eight-hour delay settings. This phase added $1,700 to her project, a cost that varies with local rates.

Conclusion

Total cost lands around $7,099 based on Katherine Englishman’s project. Before the first session, Redwood Outdoors recommends curing the wood by heating the sauna to the highest temperature for one hour. Once cured, the Mini-Cube sauna reaches 160-170 degrees Fahrenheit in approximately 40 minutes. The entire project — from unboxing to first steam — fits into a weekend plus a day for electrical.
