For a small space, measure usable interior dimensions and installation clearances, not only the exterior box. A one-person cabin can still feel cramped, and a blanket can still require a heat-safe floor area longer than the user. Confirm doorway delivery, circuit load, ventilation, and where damp towels go.
The small-space measurement sheet
Draw the product footprint, door swing, service access, ventilation gaps, user entry path, and cord or conduit route on one plan. For tubs or wet-adjacent rooms, add drainage and floor load.
- Doorway width and turning radius
- Seat width, depth, and leg position
- Controller access
- Clearance from combustible surfaces
- Drying and cleaning zone
