Where a model comes in two lengths, values are shown as shorter / longer (for example, Mini 2.0 / Mini 2.4). Dimensions are rounded to the nearest inch, from Leil’s 2026 Round Cube catalogue. *Double volume is the sauna room only; the front room is extra space.
Prices are Leil’s 2026 minimum advertised price before options; heater is extra. Freight across the continental U.S. is $1,190 for the Mini and $1,500 for the Relax, Single and Double. Recommended heaters are Leil’s own HUUM pairings — the heater-sizing tool on this page calculates independently from interior volume and may suggest a different size.

A round sauna for every season.
Handcrafted in Estonia by Leil Saunas, the Round Cube pairs a softly curved silhouette with a full mirror-glass front, 40 mm Thermowood walls and three-level aspen benches. Winner of the Red Dot 2024 “Best of the Best” design award, it is built to be used year-round, through Maine winters and summer storms alike.
-
Award-winning design
A curved, EUIPO-protected silhouette with full-circle arches, a black shingle roof and a mirror-glass front that reflects the landscape around it.
-
Four layouts
From the compact Mini to the two-room Double, with seating for 4 to 8 and an optional juniper wall and LED lighting.
-
Built to last
Thermally modified wood resists water and humidity, won’t swell, warp or leak resin, and is made for year-round outdoor use.
