Stillness has a shape. This is it.

Quantum presents the Sauna Lumi Cube, an insulated outdoor sauna for three to four people, defined by its bold cubic silhouette, full glass front facade, and warm timber interior glowing against a striking dark exterior finish. Designed to be as beautiful from the outside as it is restorative within, it sits as naturally beside a Mediterranean terrace as it does in a Nordic garden.

Built to a fully insulated standard with a dark thermwood exterior, natural pine interior cladding, and a full-height glass front that frames the sauna stove like a living artwork, the Lumi Cube is engineered for year-round performance without compromise. Its clean flat roofline and uncompromising cubic form give it an architectural presence that is quietly confident and unmistakably modern.

Key Features:

• Bold cubic form with full glass front facade
• Insulated construction for year-round outdoor use
• Dark thermwood exterior with warm pine interior
• Spacious three to four person capacity
• Full-height glass door with stainless steel handle
• Compatible with wood-fired or electric sauna stove

Dimensions: W 2340mm x D 2490mm x H 2100mm

With the Quantum Sauna Lumi Cube, every session ends with the quiet certainty that you will be back tomorrow.
