How to measure your space for a sauna
Width, depth, ceiling, the gap makers ask for around the cabin, and the delivery path most people forget.
Measure four things: the floor width and depth, the ceiling height at the exact spot, and the narrowest point on the way in. A sauna that fits the room can still fail at the stairs.
Leave a gap around the cabin
Makers ask for a gap so air can move and the cord can reach the outlet. Saunafit uses each maker's figure where it publishes one, and 2 inches otherwise.
| Maker | Sides and back | Above the roof |
|---|---|---|
| Sun Home Eclipse | 4–6 in | 12–14 in |
| Sunlighten mPulse | 4 in | 6 in |
| Clearlight Sanctuary | 2–4 in | Not published |
| Everyone else here | 2 in (our default) | 2 in (our default) |
Ceiling height
Measure at the spot the sauna will stand, not the middle of the room; basement ducts and beams often sit lower. Most indoor cabins here are 73–79 inches tall, so a 7 ft (84 in) ceiling is tight once you add the gap above. See what fits under 7 ft.
The way in
Indoor infrared cabins ship as flat panels; Sun Home puts assembly at 30–90 minutes for a 2-person model, so doorways rarely block them. Big outdoor units are different. The heaviest here are Sun Home Solaris 4 (1,698 lb), Sun Home Luminar 5 (1,070 lb), Sun Home Luminar 2 (970 lb); check the path for a pallet before you order one.
Outdoors
Plan a level, drained base. Barrel saunas sit on cradles; cabins usually want pavers or a slab. Measure the footprint including any roof overhang, which some makers list separately.
