Up close

Heat it up.

Scroll: the Onyxia Cube warms from 20 to 85 °C in front of you.

Inside the Onyxia Cube
20°CInside the cabin

20 °C. Across the garden.

The stove has been on for forty minutes; the glass wall is already fogging.

55 °C. The door closes.

Outside it is January. Inside, thermo-pine and stones taking the heat.

85 °C. Then the cold.

A ladle on the stones, five minutes more, and the walk back across the grass is the best part.

Onyxia Cube, the heat
The heat · Outdoor saunas

A stove for a bigger room.

A Vulkano Black 4.5 kW electric stove heats a load of olivine stones; the air reaches 80 to 85 °C in 30 to 45 minutes. Pour a ladle of water on the stones and the humidity jumps for a minute: the löyly. The stove is chosen with us, 4.5 kW recommended, and fitted at delivery.

Inside

A terrace, then the heat.

Most outdoor models have a porch or a covered terrace: a bench to cool down on between rounds. Inside, abachi or spruce benches, a Vulkano or Harvia stove and LED lighting on the Holl's. A tinted door keeps the heat and the privacy.

Before it arrives

What the Onyxia Cube needs from your home.

Four things we check on the visit. A garden sauna is a shed with a stove: a base, a cable, a day of assembly.

230 V · dedicated line

4.5 kW stove: a dedicated 20 A line with RCD to a box by the cabin. Our electrician does it, or yours with our drawing.

A footprint of 210 × 160 cm

A level, drained base: slab, paving or a deck. Leave 10 cm around it for air.

Built on site in a day

Delivered on a pallet and assembled by our team on your base, stove connected and tested the same day.

A buried supply cable

From the house to the cabin in a conduit, sized for the stove. Ours or your electrician.

Among the outdoor saunas

Onyxia Cube, Mirror 200 or Hestia?

Accessories

Make the Onyxia Cube yours.

What comes in the box with the Onyxia Cube and what you can add. A sauna needs very little: the stove and its stones if they are not included, a headrest or two, and the bucket for the steam.

IncludedFloor protection mat

Protects the floor under the cabin and gives grip when wet.

OptionalSauna stove

Harvia stove, 4.5 kW, with the stones.

Choose the stove with us: 4.5 kW recommended
OptionalBucket, ladle, thermometer, hygrometer and hourglass

The traditional kit for pouring water on the stones and reading the room.

OptionalSauna stones

Olivine stones for the stove: they hold the heat and take the water for the steam.

OptionalHeadrest

A curved wooden headrest for lying back on the upper bench.

OptionalComfort backrest

A slatted backrest that clips onto the bench for a longer session.

OptionalChromotherapy lighting

LED colour lighting cycles or holds one colour for the session.

OptionalEssential oils

Eucalyptus, pine or birch for the water bucket.

OptionalWeather cover

A breathable cover for the roof and door in the wet months.

OptionalWi-Fi control

Start the stove from your phone so the cabin is at temperature when you get home.

1 included · 9 options. Prices for options on request; we quote them with the spa so there are no surprises on the day.

Sit in a Holl's before you decide.

There are saunas heated in the showroom in Nerja: sit in an infrared cabin and a Finnish one, ten minutes each, and the choice makes itself. Georgie, Martin or Patri will talk you through the room, the socket and the monthly figure.
