MTI Shower Base | Multi Threshold Shower Pan
Low-profile multiple-threshold shower bases let you specify glass enclosures on one, two or three sides. This means you choose a one, two or 3 sided tile flange at no additional cost. This Rigid ABS tile flange is chemically bonded to the shower base at the factory. This not only facilitates installation but, also enables a watertight seal on any sides specified.The low-profile design not only presents a very clean look, but it also makes entrance and exit easier. The shallow height of these base thresholds also permits them to be recessed in the floor. When used in combination with a genuine teak shower tray, a flat transition is created between bathroom floor and shower.


MTI Multiple Threshold Shower Base
These MTI shower bases can be installed in a corner, alcove or against the wall. You can be specified to accept glass enclosures on one, two or three sides. Find shower bases in Acrylic, DoloMatte or Mineral Composite.
