Your steam shower will arrive in 1-3 wooden boxes or less depend on the model, and all crates will go through any door way of 28″ or wider. Unlike some stories we have been told, our steam showers come largely pre-assembled with the massage jets, electric wiring and water pipes already connected. The unit is supplied with its constituent panels flat-packed for easy maneuvering through doorways. These adjoining panels will be bolted together and sealed with silicone to provide a relatively straight forward installation. Simply connect any pipes/wires that join the plumbing/electrics between adjacent panels, hook up your hot and cold-water feeds, electric supply and waste drainage and you are ready to go.
