How to Install a Shower Door

Print this article

A glass shower door looks better, is easier to clean and more effective at keeping your room dry than a shower curtain. Whether replacing a curtain, fitting a new shower, or replacing an old shower door, our guide will help you through each step.

Step 1

Plan Position of Door

Plan Position of Door

Measure the opening of your shower cubicle and buy a shower door to fit. Carefully plan the position of the door, marking the points with a marker. With a utility knife, cut away any rubber or plastic seals on the top of the shower pan that might interfere with the installation of the door.

Step 2

Mark Mounting Holes

Mark Mounting Holes

Place the U channelled support bar of the door where it will be positioned. Using a spirit level to ensure the side support bar is vertical, mark the position of the mounting holes using a marker. Remove the support to reveal your drill marks.

Step 3

Drill Holes

Drill Holes

Before drilling into any wall, always check for any wires or pipes behind the wall using a multi-purpose detector. When deemed safe, drill the mounting holes. If drilling into tiles, use a diamond tipped tile drill bit. For help with this step refer to our guide “How to Drill a Hole in a Ceramic Tile”. Insert suitably sized wall plugs into each hole.

Step 4

Screw in Support Bar

Apply a small bead of silicone sealant to the back of the support bar and attach the support bar firmly to the wall. Then screw the bar into place with the drill. Support bars need to be fitted to both sides so repeat these steps for the other side too.
