Product Highlights
Thermal Spruce Construction — No Exposed Fasteners
The Cubist sauna room — walls, benches, and flooring — is built entirely from thermal spruce. Thermal modification gives the spruce enhanced moisture resistance and dimensional stability: reduced moisture absorption, improved resistance to the heat-and-humidity cycling of sauna use, and a clean surface that does not develop the resin pockets untreated spruce can produce at sauna temperatures. The no-exposed-fasteners construction keeps interior walls and bench surfaces free of visible screws or nail heads.
9kW Stainless Steel Heater with Incoloy Elements
The Cubist heater is a 9kW wall-mounted unit in stainless steel — the corrosion-resistant standard for sauna heater construction in a high-humidity environment. Its Incoloy heating elements are a nickel-chromium alloy engineered for high-temperature, long-cycle performance, resistant to oxidation and thermal fatigue. The built-in high-temperature shutoff is a standard safety feature, the heat deflector protects the wall behind the unit while directing warm air downward, and 50 lbs of sauna stones are included and pre-loaded.
Cubist Design — Clean Lines, Black Shingle Roof
The Cubist collection is Mr. Steam's contemporary geometric design line — clean lines and precise angles that read as architectural rather than rustic. Against the thermal spruce exterior, the black shingle roof creates a clean contrast that positions the Cubist as a designed backyard structure, compatible with modern residential architecture in a way that traditional barrel or cabin-style saunas are not.
Digital Touchscreen Control with Fan and Lighting
The wall-mounted touchscreen digital display manages the full Cubist session — on/off, fan, temperature selection, and lighting control in a single panel. Fan control matters for session management: circulating air within the sauna room affects heat distribution and recovery time between sessions. Combined with the remote-controlled LED backrest uplighting, the session environment is fully adjustable without leaving the bench.
Complete Accessory Package
The Cubist includes the full sauna session accessory set: a water pail and ladle for löyly — pouring water on the stones to create steam — and a room thermometer/hygrometer for monitoring temperature and humidity during the session. Nothing needs to be separately sourced before the first session.

Important Information
Made to order: the Cubist is built after order confirmation, with a minimum 4-week lead time to build and ship. Plan your order timing accordingly, and contact us for the current production lead time if your timeline is specific. Shipping is free; a tracking number is emailed once shipped and is active within 24 hours. Orders are not shipped or delivered on weekends or holidays.
Electrical required: the 9kW heater requires a dedicated 240V/1-phase outdoor-rated electrical circuit (typically 40–60A), installed by a licensed electrician before delivery; the circuit is not included. The included Heater Contactor Box provides the connection point for the heater.
Site and installation: a level, solid surface is required — a concrete pad or solid pavers — and site preparation is not included. Professional assembly and installation are recommended given the room size and electrical connection requirements. A permanent outdoor sauna room with an electrical connection may require a building permit; verify local requirements before ordering.
Frequently Asked Questions
What does "made to order" mean for lead time?
The Cubist is built after your order is confirmed — it is not pulled from inventory. The minimum lead time is 4 weeks to build and ship, and the actual ship date depends on current production volume. Contact us for the current lead time before ordering if your timeline is specific.
What electrical connection does the heater require?
The 9kW heater requires a dedicated 240V/1-phase circuit, typically 40–60A, installed by a licensed electrician. The Heater Contactor Box included with the Cubist provides the connection point. Confirm exact amperage requirements with your electrician before ordering so the circuit is ready before delivery.
Can I pour water on the stones (löyly)?
Yes — the Cubist heater is a traditional stone heater loaded with 50 lbs of sauna stones, and the included water pail and ladle are for exactly this purpose. Pouring water on the heated stones produces steam (löyly), and the Cubist supports both dry heat sessions and steam sessions depending on your preference.
How does the Cubist compare to the Thermasol saunas?
The Cubist is a Mr. Steam brand sauna with a 7' × 7' footprint, a traditional stone heater, and a geometric design. The Thermasol saunas use Harvia heaters with more emphasis on glass and modern exterior design, and the Thermasol Solaris is solar-powered. The Cubist is the most accessible price point in the lineup and includes the traditional stone-heater löyly experience.
The Mr. Steam Cubist is the complete outdoor sauna room — everything included, built to order in a minimum of 4 weeks, and designed to look like it belongs on a modern patio. At $15,080 with free shipping, it is the sauna that does not leave anything off the list.
