Prefab Outdoor Sauna Buying Guide (2026): Sauna Buildings, Sauna Houses and Glass-Front Saunas
Quick answer: A prefab outdoor sauna arrives finished or nearly finished, so there is no on-site build. There are three main types: finished sauna buildings delivered as one module (Sweaty Yeti, from $29,700), sauna houses with a lounge and sometimes a shower (Genevas, from $27,900), and compact glass-front outdoor saunas (SOLENNE Altura, $7,999). Before you order, plan a level foundation, a dedicated electrical circuit by a licensed electrician, a delivery route (often with a crane or forklift for larger units) and any permits or HOA approval.
“Prefab” covers very different products, from a compact glass-front sauna that ships on a pallet to a full building set by crane. This guide compares the three types we sell as an authorized retailer, using published specifications and prices, so you can choose the right one for your property and budget.
The three types of prefab outdoor sauna
1. Finished sauna buildings (Sweaty Yeti)
Sweaty Yeti builds complete wood-framed sauna buildings: insulated walls (R-13), ceiling and floor (R-30), fiber-cement board-and-batten siding, asphalt shingle roof and a cedar sauna room with a HUUM Steel electric heater. Models range from the compact Sweaty Yeti Sauna (8′ × 9′, 4–6 people, $29,700) to 8′ × 17′ buildings that add a changing room, a cold plunge room or a workout room, or the 8–12 person Sauna Max ($46,900).
2. Sauna houses with a lounge (Genevas)
Genevas builds modular sauna houses in Estonia from 60 mm cross-laminated timber (CLT) with double glazing and Thermoalder benches. Both models combine a sauna with a separate lounge: the Zermatt (2.2 × 3.2 m, sauna + lounge, up to 5 people, $27,900) and the St. Moritz (5.6 × 2.2 m, sauna + lounge + shower, up to 5 people, $42,900).
3. Compact glass-front outdoor saunas (SOLENNE)
If you want a sauna without a building project, a compact unit is the simplest route. The SOLENNE Altura measures 71 × 71 × 77 in, with a charcoal frame, an overhanging roof, panoramic front and side glass and two-level timber benches. It costs $7,999 with free curbside delivery to the lower 48 states + DC.

Site preparation: foundation, power, access
Foundation
Every outdoor sauna needs a stable, level base. Sweaty Yeti specifies a foundation that supports the unit’s weight, such as level ground, gravel or a concrete pad. Genevas provides a foundation drawing; common options are a concrete slab or screw piles. The SOLENNE Altura needs a stable, level and drained base suited to the exterior setting.
Electrical
Almost every electric outdoor sauna needs a dedicated circuit, installed by a licensed electrician. Sweaty Yeti publishes the service per model:
| Sweaty Yeti model | Standard | With mini-split |
|---|---|---|
| Sauna | 60 A | n/a |
| Sauna Plus | 60 A | 80 A |
| Sauna Max | 70 A | n/a |
| Sauna Plunge | 70 A | 80 A |
| Sauna Plus Barrel Plunge | 70 A | 80 A |
| Sauna Fit | 60 A | 80 A |
For Genevas, the heater circuit is confirmed in your written quote. For SOLENNE, voltage, circuit rating and connection method are confirmed in writing for your order before dispatch.
Access, permits and HOA
Check zoning, setbacks and HOA rules before you order. Then walk the route: gates, slopes, trees and overhead wires decide whether a truck can reach the spot and whether a crane or extended-reach forklift is needed. Sweaty Yeti buildings and Genevas sauna houses are large structures; the Genevas St. Moritz alone weighs about 2,500 kg.
Delivery and timelines
| Brand | Published timing | Delivery |
|---|---|---|
| SOLENNE | 4–6 weeks for the saunas, confirmed for your address | Free curbside freight, lower 48 + DC |
| Genevas | About 10–16 weeks from order confirmation | To the lower 48 + DC; freight, duties and unloading itemized in your quote |
| Sweaty Yeti | Delivery review usually 4–5 days after your deposit; materials are ordered once the balance is received | Delivery, set and any crane service confirmed in your written final price |
How buying works
The three brands use different purchase processes, and each one protects you before the big payment:
- Sweaty Yeti: a 10% deposit, credited toward the price, starts a transportation and site review. You receive your final price in writing; the deposit is refunded in full if delivery isn’t feasible or the order is declined.
- Genevas: a free written quote with the project total, deposit, payment schedule and cancellation conditions before you pay anything.
- SOLENNE: order online or request a quote. We review your route and electrical requirements before dispatch, with a full refund if we can’t deliver to your site.
Warranties: Sweaty Yeti structures carry the Irontown Homes Limited Warranty; Genevas and SOLENNE each carry a 2-year manufacturer’s warranty. Chic Home Deco is your first contact for any claim.
Pre-order checklist
- Measure the spot and add clearance around doors and for maintenance.
- Confirm zoning, setbacks, permits and HOA rules.
- Ask a licensed electrician to quote the dedicated circuit.
- Plan the foundation (gravel, pad, slab or screw piles) for your model.
- Walk the delivery route for the truck and any crane or forklift.
- Decide on extras: changing room, lounge, shower or a cold plunge.
