Expert help that stays with you

Small details become expensive problems once installation begins. We ask the questions early, so a mismatched part, an overlooked requirement or an installation issue gets caught while it is still easy to fix.

Our job does not end when your order ships. We stay available through installation and beyond. If something needs attention, we stay involved, work the problem, and help see it through.

We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Sauna and heater customers also receive free shipping on sauna accessories for life.

Planning a sauna, or need help with one you purchased from us? Our founders have built saunas from the crate up and both run saunas at home. New customers and existing Sauna Marketplace sauna and heater owners can Open the 3D planner.

How It Fits

How This Product Fits the System

What it is used for

An electric sauna heater that heats the sauna room and stone mass for traditional löyly. Choose the output from adjusted room volume, then match the exact voltage, phase, circuit, controls, stones, clearances, and ventilation.

What to plan

  • Size from adjusted sauna volume, including the effect of glass, masonry, and other uninsulated surfaces; do not size from floor area alone.
  • Match the selected model's power or fuel, voltage, phase, circuit, wire, control, stone, and venting requirements before ordering.
  • Treat clearances, ceiling reference planes, ventilation, guarding, floor protection, and service access as one room-layout decision.
  • Follow the current installation manual and use a qualified installer.

The Wall Electric Sauna Heater by Harvia

A wall-mounted heater that leaves more floor open. 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.
