We quote per project rather than publish a range, because the same specification lands at a very different total from one building to the next. What moves the figure is the size of the cabin or wet room, the timber and stone grade, the heater or steam generator selected, how much of the enclosure is glass, the waterproofing, tanking and drainage the room already has, and how far power, water, drainage and ventilation have to be brought to it. Send us the room dimensions, the ceiling height, the access route and the services already reaching the space, and we return an itemised, position-by-position quotation covering equipment, construction and installation.
