Sauna sizing is more nuanced than just "how many people fit." The actual question is: how does your household use the cabin, and what's the realistic peak load? A 2-person cabin is right for daily solo use even if you have a household of 4. A 6-person cube is wasted for daily solo recovery but ideal for hosting friends.
2-person saunas — the daily recovery cabin
2-person infrared cabins are the default choice for most North American buyers. They fit in a corner of a basement, garage, or master bathroom. They plug into a standard 120V outlet. They're sized for solo daily use with the option of a partner.
The bench layout in a 2-person cabin is typically a single straight bench (sometimes with a backrest) — you sit upright, lean against the wall, and either solo-meditate or pair-recover. Total cabin footprint is about 48"W × 44"D × 78"H.
STEALA's 2-person options: Vessna ($2,999) and Velsund ($3,499). The Reserve adds Himalayan salt panels and a chromotherapy LED bank.
3-person saunas — the small-household compromise
3-person cabins are the right pick if your household actually uses the sauna together, or if you want the option of bringing one friend along. The bench layout in a 3-person cabin is typically L-shaped — two people on the upper bench, one on the lower, or one stretched out reclined.
The Myrren hybrid is a 3-person outdoor cabin that does both infrared and traditional steam. Footprint is about 72"W × 60"D × 84"H — it needs outdoor space and a 240V circuit. Best for households of 2–4 adults where two people will typically sauna together.
4-person saunas — the ritual cabin
4-person barrel saunas are where the form factor starts to feel like a destination, not just a fixture. The Brynsund 4P barrel seats 4 adults — two on the upper bench, two on the lower (or two reclined on the upper). It's outdoors, it needs site prep, and it's a full Scandinavian ritual setup.
Sweet spot if: you host friends regularly, you have backyard space, and you want the authentic Löyly experience without going to flagship cube tier.
6-person saunas — the flagship social cabin
6-person cubes are for households that entertain. The Norhelm 4-6 person premium cube has an L-bench layout: a 6'2" upper bench plus a 4' return bench. Seats 4 adults reclined or 6 upright. Floor-to-ceiling glass on three sides means it doubles as architectural showpiece, not just utility.
Reality check: most days, you'll use a 6P cube with 1–2 people. The capacity is there for the dinner-party night, the holiday weekend, the post-cold-plunge social ritual. If you're never going to host more than 2 people, a 4P barrel is better value.
Decision flowchart
- How many people sauna at once in 95% of sessions? 1–2 → 2-person infrared. 2–3 → 3-person hybrid. 3–4 → 4-person barrel. 4+ regularly → 6-person cube.
- Indoor or outdoor space? Indoor only → infrared 2P. Outdoor available → any of the others.
- 120V outlet only, or willing to wire 240V? 120V only → infrared 2P (Vessna or Reserve). 240V OK → any of the steam/hybrid options.
- Daily recovery vs ritual destination? Daily recovery → 2P infrared. Ritual destination → barrel or cube.
