At SaunaMed we have made sure our sauna cabins are self-venting and require no plumbing. There is a sliding vent to control the exhaust of hot air and the unit stands off the floor on 4 cleverly designed supports so no further venting is required and your floor remains protected.
Not only does this mean less hassle and cost for the end user but it enables ultra portability, you literally have a sauna wherever you desire even a caravan or a motorboat. Not only this but when it comes to moving home you can easily take your sauna with you.
