5x6 Outdoor Sauna
A compact outdoor sauna that fits in smaller backyards without compromising on the sauna experience. 6kW electric heater, parallel bench layout, and a straightforward build process.
This is a full design package for a 5x6 outdoor sauna — one of the most practical sizes for a backyard build. The compact footprint keeps material costs down and simplifies the build, while still giving you a proper hot room with a parallel bench layout that seats 2–3 people comfortably. The design uses a 6kW electric heater with digital controls mounted outside the sauna in a weatherproof enclosure. Cedar tongue-and-groove paneling on the interior, fiberglass insulation (with mineral wool as an option), and aluminum foil vapor barrier. The exterior uses T1-11 siding on a deck block foundation — no concrete work required. The plan covers 14 construction phases from foundation to final finishes.
