When designing your new shower enclosure, keep in mind that each glass panel needs to be at least 4 1/2″ wide, which is the minimum width for tempering glass and supporting the hardware.  Also, the door will need to be a minimum of 22″ wide and no more than 36″ wide.

Walls which meet a door or glass panel need to be completely vertical, or “plumb”, in order to prevent gaps, uneven joints, and hinge “bind”.  This means the wall can’t lean in any direction, or be “bowed” or “bellied”.  Any walls that are more the 1/4″ out of plumb make it difficult to install a […]

Design a built-in shower seat to slant toward the drain at a 5° (approx. 3/16″ to 1/4″) slope so water flows off the seat and into the drain to prevent water from standing or pooling if the seat is angled backwards.

The curb or lip around the bottom of the shower should be slanted inward at a 5° (approx. 3/16″ to 1/4″) “pitch” or slope so water flows in toward the drain.  A level curb would cause the water to leak onto the bathroom floor.
