Cube Saunas
Ula Mini Beige.The three-person cube.
Our compact cube sauna in warm beige thermowood, three-person capacity in a footprint that fits most urban gardens.
Overview
Ula Mini Cube Sauna, Beige.
The Ula Mini sits between the two-person Micro and the four-person Classic, a properly-insulated cube in warm beige-toned thermowood with a single-tier bench sized for three adults or a couple with a child.
It's the specification that most often fits the 'I want a real cube sauna but I don't have room for a Classic' brief. External footprint is 2.0 x 1.8m, clears most standard urban side gates and fits gardens the Classic wouldn't.
Everything else is full spec: 100mm rockwool, hemlock interior, 7kW Harvia heater, panoramic glass front, 10-year structural warranty. Nothing about the construction is compromised for the smaller size.

Living with it
How it actually works day to day.
The Mini is genuinely the practical family cube for tight gardens. Three-person capacity covers most daily use, a parent and two kids, three friends, or a couple with plenty of stretch room.
Access is straightforward. External width under 2m clears standard 900mm side gates on a two-person carry, so we don't need crane lifts for most installs.
Running cost is negligible compared to a barrel of the same capacity because the cube is properly insulated. The 7kW heater rarely runs at full duty-cycle once the room is at temperature.




Best for
Who typically buys this one.
- Urban and suburban gardens with restricted space
- Families of 2–3 or a couple + occasional guest
- Buyers wanting an insulated cube on a modest budget
- Gardens with 900mm side-gate access constraints
