Installing a Waterproof Shower Pans

The shower kit includes a one-piece square base, and wall panels that are attached directly to the wall studs. Even though the panels are made of hard plastic, they are fragile and must be handled carefully. In addition to the base and wall panels, the kit includes glass side-walls and a glass door. To assemble and install the unit, follow the directions provided by the manufacturer.

Installation Steps
  • Install the Floor Drain
  • Install the Base
  • Install the Wall Panels
  • Complete the Glass Enclosure
  • Finish the Bathroom Walls




Install the Floor Drain: In this kit, a floor-drain strainer and connecting drain pipe must be installed before the shower base is installed. First, fit the neoprene gasket onto the stem of the floor-drain’s upper section and insert the stem into the base, then screw the lower section onto the stem from below the base.
Attach a pipe tailpiece to the floor-drain stem, using cement. After the base is in position, this tailpiece is attached to the rough-in plumbing from below.


Install the Base: To provide a solid, non-slip footing for the shower base, apply a 1″ thick layer of drywall compound on the floor tiles or the sub-floor.
Embed the shower base in the compound before it dries.


Install the Wall Panels: The first wall panel includes the corner piece and extends to the right. Take extra care to level and position this panel correctly because it will affect the position of the rest of the shower components. Use 1-1/2″ galvanized roofing nails to fasten the first wall panel through slots provided on the panel flange. Measure the location of the shower-head pipe and valve. Then transfer the dimensions to the second wall panel. Accuracy is essential. Bore holes for the plumbing outlets in the second wall panel. Use a 3/4″ Forstner bit for the shower pipe hole. If required, larger holes for the shower handles can be drilled with a hole saw or expanding bit. Place scrap wood blocking under the panel to prevent the drill bit from breaking through and cracking the plastic.
After the holes are drilled, position the second wall in place. This section slides into place and connects with molded plastic fittings. Secure it to the wall studs with nails through the nailing flange, as on the first panel.


Complete the Glass Enclosure: Before closing in the shower, attach the shower head and operating valve.
Attach the glass panel retaining channels to the wall sections.
Secure the glass inserts in the retaining channels. Add edge trim strips if provided.
Install the shower door according to the kit instructions.


Finish the Bathroom Walls: Finish the walls adjacent to the shower kit by installing moisture-resistant (green board) drywall directly over the plastic flanges.
