Our ILLI Cube Sauna

The ILLI Cube is a modern garden sauna crafted for those who seek to blend everyday life with the understated luxury of the Scandinavian lifestyle. Its compact form, carefully selected natural materials, and minimalist design make it the centerpiece of any relaxation space—whether nestled in a garden, placed on a terrace, or integrated into a private spa.

 

Constructed from Thermowood, a thermally treated timber, the ILLI Cube offers not only refined aesthetics but also exceptional durability and weather resistance. This ensures the sauna retains its shape, strength, and charm for years to come. The wood’s warm, rich tone and subtle texture exude natural beauty that deepens gracefully over time.

 

Inside, the ILLI Cube is designed with comfort and atmosphere in mind. A large glazed front of tempered glass opens the interior to the surrounding nature, creating a seamless connection between the warmth of the sauna and the tranquility of the outdoors.

Intallation & Electrical Information

Sauna Base

You can either install a base yourself or by a professional following our guide below. A base is required due to the weight of the sauna and avoids your sauna from sinking over time.

 

Base Installation Guide

 

Self-assembly instructions will be provided. We highly recommend you hire a professional carpenter and/ or joiner for your flatpack sauna build.

 

Electrical

Domestic sauna heaters in the UK usually require a dedicated single-phase 230V supply, similar to an electric shower or cooker, and installation must be carried out by a qualified electrician. The current draw depends on the heater’s kW rating and can be estimated using watts ÷ volts = amps (for example, 6 kW ≈ 26 A). Smaller heaters around 2–3.6 kW typically need 10–15 A with 1.5–2.5 mm² cable, while larger units from 4.5–9 kW may draw 19–40 A and require 2.5–6 mm² or heavier cabling depending on the run length. For more information, please check our guide below.
