PrincipleA braced road-trailer chassis is the permanent base, so the sauna is fully mobile.
SuitabilityMobile saunas for rentals and events that must be towed between sites.
SoilsNeeds only level, firm ground and chocking on site; no ground works.
Frost heaveNot applicable — the unit is not fixed to the ground and is repositioned as needed.
DrainageHandled by a sealed floor draining off the deck; the site simply needs to shed water.
Build difficultyProfessional

A trailer foundation makes the sauna mobile: a braced road chassis is the base, so it tows between sites and sets up on level ground with no ground works. Road weight and height limits shape the whole build.
