There’s nothing like a nice hot bath. Now MTI keeps your bath hot longer. Its inline water heating systems maintain bath water at a comfortable 102°F so you can enjoy your bath for as long as you like. For added comfort, MTI offers its Radiance® system that brings radiant heat into the bath structure to warm your neck, shoulders and back. The heated bath shell is not only comfortable for the bather, but also helps prevent heat loss from the bath water.
