MrSteam Cubist Outdoor Sauna Room – Thermal Spruce 9kW Sauna

Bring a refined sauna experience outdoors with the MrSteam Cubist Outdoor Sauna Room, a contemporary retreat designed with clean architectural lines, natural Thermal Spruce, and an integrated traditional sauna heating system.

Part of MrSteam’s Cubist Collection, this outdoor sauna combines modern design with the warmth and character of wood construction. The sauna room, benches, flooring, and walls are crafted from Thermal Spruce with no exposed fasteners, creating a polished, streamlined interior suited for upscale patios, pool areas, and dedicated backyard wellness spaces.

A glass front door with chrome hinges and a Thermal Wood push-pull handle complements the minimalist design, while the black shingle roof system helps prepare the structure for outdoor installation.

Inside, integrated white LED backrest uplighting creates a relaxing atmosphere and can be switched on, off, or dimmed using the included remote control.

Traditional Sauna Heat

The Cubist is equipped with a 9kW stainless-steel sauna heater designed to produce the classic dry-heat sauna experience.

Incoloy heating elements, a built-in high-temperature shutoff, and a heat deflector are incorporated into the heater design. The system also includes 50 lb. of sauna stones, allowing heat to radiate throughout the room for an authentic sauna environment.

A wall-mounted digital touchscreen provides convenient control over key sauna functions, including:

• Power on/off

• Temperature selection

• Fan operation

• Lighting

Premium Thermal Spruce Construction

Thermally modified Spruce gives the Cubist its distinctive natural appearance while complementing the demands of a dedicated outdoor sauna.

The concealed-fastener construction further enhances the clean, architectural aesthetic, allowing the natural wood and geometric form to remain the visual focus.
