Questions and Answers for Swan 34 in. x 42 in. Solid Surface Single Threshold Center Drain Shower Pan in Bone

A:  A single threshold mean that there is one side that is the entry point. The other three edges have a flange that is designed to fit behind the shower wall for a water tight installation. In this case, the threshold/entry point is on the 42" side (left to right width of the floor) and this is where the shower door would be installed. We hope this information helps you make a decision on your bath remodel and appreciate you considering Swan products for this project.
