Harvia The Wall comes in 6 and 8 kW for sauna rooms from 141 to 423 cubic feet, with built-in illuminated controls and black or stainless steel finishes. The mounting rack supports left- or right-handed installation, which makes it easier to work around the bench and door layout.

Small footprint, controls included

The Wall is for the room where a floor-standing heater would take up space you would rather give to the bench. It mounts to the wall, sits 10.15 inches deep, and keeps the timer and temperature controls on top of the heater.

The honest way to size it

6 kW: sauna rooms up to 282 cubic feet.
8 kW: sauna rooms up to 423 cubic feet.

Use the adjusted room volume before choosing. Glass, tile, masonry, and other uninsulated surfaces can make a small room behave like a larger one.

Installation details

16.9 in wide x 10.15 in deep x 27.59 in high.
Black or stainless steel finish.
Left- or right-handed installation.
Built-in illuminated timer and temperature controls.
Mounting rack, overheat protection, and stone protector included.

The direct rock-to-element layout moves air through the stone cavity while the wall mount keeps the heater footprint out of the aisle.

What comes with it

The heater, mounting rack, installation and operation manual, a two-year full warranty for consumer use, and a five-year service warranty are included. Stones are selected separately above.

Send us the room dimensions, ceiling height, and any glass or masonry. Call or text (844) 565-1113, and we will check the 6 versus 8 kW decision with you.
