THERMASOL® engineers have used the proven science of convection to create an industry first - the SteamVection steam head. This state-of-the-art design delivers floor-to-ceiling temperature uniformity within the steam shower while adhering to THERMASOL®'s trademark functionality, design and safety. For users, this means consistent and even temperature zones - no longer variable heat ranges that typically occur in steam showers. THERMASOL®'s steam head also allows the closest proximity to the outlet called, "the steam emitting area." This is a mere three inches from the wall, thereby avoiding intrusion into one's usable shower space. SteamVection by THERMASOL® "The Superior in Safety".
