Why the 8 kW Size
The Wall 8 kW is rated for sauna cabins between 250 and 425 cubic feet, best for large residential / family-size sauna cabins (4+ person). Calculate your cabin volume as interior length × width × height. If the cabin includes a glass door or window, add roughly 25% to the calculated cubic footage to compensate for radiant heat loss. For smaller residential saunas (under 250 cu ft), see the Wall 6 kW sibling product.
What's Included
Each kW size is offered in two package configurations. Pick the size first from the selector above, then pick the package from the dropdown on the product page.
| Package | Includes |

| Wall With Stones |

Sauna Stones
Every "Wall With Stones" package ships with one box of Harvia AC3000 standard sauna stones, olivine diabase, 5–10 cm size grade, 20 kg (44 lb) per box. AC3000 is the correct stone size for The Wall's stone column. The smaller 5–10 cm size grade packs more densely than the larger 10–15 cm AC3020 grade, giving you more thermal mass and more even löyly when water hits the stones. If you prefer to source stones locally, pick the "Just Heater" package; stones are sold separately.
Installation & Electrical Requirements
The Wall 8 kW requires a dedicated 240V 1-Phase circuit (33 Amps, 8 Gauge Copper) wired by a licensed electrician. The Wall is UL Listed and must be installed per the included manual and local electrical code. Consult the PDF manual below before framing-in.
