Product Highlights
180 lb Stone Capacity
The Cilindro PC90’s tower design accommodates up to 180 lbs of sauna rocks (sold separately), significantly more than most wall-mount heaters. This large stone mass supports effective heat retention, even temperature distribution, and consistent steam generation throughout the sauna session.
9KW Output for Larger Sauna Rooms
With 9.0 kilowatts of heating power at 37.5 amps, the PC90 is rated for sauna rooms between 282 and 494 cubic feet. Confirm your room volume before ordering to ensure this heater is appropriately sized for your space.
Built-In Controls with Programmable Timer
The PC90 includes an integrated control panel with a 1–8 hour programmable timer and pre-set functionality. No separate wall-mounted control unit is required, keeping the installation straightforward and the sauna wall uncluttered.
Floor-Standing Tower Design
Unlike wall-mount heaters, the Cilindro PC90 stands on the sauna floor and can be positioned in a corner or along a wall depending on your room layout. The tall cylindrical profile (40" H) creates a distinctive visual presence while maximizing stone capacity within a compact footprint (14"W × 13"D).
Stainless Steel Cylindrical Exterior
The tower body is constructed from stainless steel, providing corrosion resistance in the high-humidity sauna environment and a clean, modern aesthetic that complements both traditional and contemporary sauna interiors.
UL Listed & Made in Finland
The PC90 carries UL listing for verified electrical safety compliance and is designed and manufactured in Finland by Harvia, a long-established Finnish sauna equipment manufacturer.
