Cube Saunas
Ula Classic.Full glass. Beige timber.
The Ula Classic cube in warm beige-toned timber with a full-glass front, the panoramic view specification of our most popular cube range.
Overview
Ula Classic Beige Full-Glass Cube Sauna.
The Ula Classic is the workhorse of our cube-sauna range, an insulated timber-frame cube in warm beige-toned thermowood, with a full-glass front wall that turns the whole gable into a window.
It's the specification that best answers the question 'I want a cube sauna, not a barrel, what's the best value?' Everything inside is proper spec: 100mm rockwool insulation, knot-free hemlock lining, Harvia 8kW heater, digital control panel.
The full-glass front is the design feature. Rather than a small glass door in a solid wall, the entire gable end is toughened glass, panoramic view of the garden while sitting at 90°C, and the sauna reads as a lantern at night.

Living with it
How it actually works day to day.
The beige finish is subtle and versatile. It's not white, not ebony, it's a warm honey-natural that sits into cottage gardens, modern gardens, coastal gardens, walled gardens. If you're unsure what colour finish will suit your space, this is the safe answer.
The full-glass front is more than a window. Sat inside at 90°C looking at the garden, the sauna experience is transformed, you're not shut in a hot box, you're sat in a warm outdoor pavilion. Owners consistently say this is the single detail that makes the sauna feel worth the money.
Because it's insulated, running cost through a Scottish winter is materially cheaper than an uninsulated barrel of the same footprint, the heater holds temperature at low duty-cycle once the room is warm.


Best for
Who typically buys this one.
- Buyers wanting a cube sauna at best value
- Owners unsure between ebony/teak/white, beige is the versatile answer
- Gardens where the sauna faces a view worth looking at
- First-time sauna owners wanting a properly-insulated cube spec

Insulation, headroom, and architectural fit. Cubes are properly insulated, so cheaper to run. They have 2.1m interior ceilings so tall users aren't stooped. And they sit square into contemporary garden schemes. Barrels are cheaper and heat faster; the choice is about how you'll use it and how it sits in the garden.
