Cube Saunas
Ula Micro Ebony.The two-person design piece.
Our smallest cube sauna in Shou Sugi Ban ebony, sized for two, engineered to full spec, for gardens where every inch counts.
Overview
Ula Micro Cube Sauna, Ebony.
The Ula Micro is the answer to 'I love the cube spec but I've genuinely got no space.' It's a properly-insulated 1.8 x 1.6m cube in Shou Sugi Ban ebony, two-person capacity, single hemlock bench, panoramic glass door.
Everything is scaled but nothing is compromised. Full 100mm rockwool insulation, knot-free hemlock lining, 6kW Harvia heater sized for the compact internal volume, EPDM flat roof, 10-year structural warranty.
It's the specification we install into townhouse courtyards, small mews gardens, and rooftop terraces, spaces where a Classic wouldn't fit but the owners still want a proper Scandinavian sauna experience.

Living with it
How it actually works day to day.
Two-person capacity is honest. This is a couple's sauna, one bench, sized for two adults side by side or one lying full-length. It's not the sauna for entertaining. It's the sauna for daily use as a personal amenity.
The compact volume means the 6kW heater brings it to soaking temperature in 20 minutes on a duty-cycle equivalent to a large kettle. Running cost per session is genuinely modest.
The Shou Sugi Ban exterior on a Micro is disproportionately effective. On a 1.8m cube, the charred black surface makes the object read as considered, like a piece of garden sculpture rather than a shed.
Best for
Who typically buys this one.
- Urban townhouse and mews gardens
- Rooftop terraces (subject to structural survey)
- Couples wanting daily-use spec
- Design-forward owners in tight-space postcodes

Yes, this is a couple's sauna. The bench seats two adults side by side or one lying full-length. Three is possible squeezed on the bench edge but not comfortable. If you want family capacity, look at the Ula L.
