Whether you are installing a new fiberglass shower surround or need to mount shelves or caddies on the shower walls, you likely need to drill into the fiberglass walls. Fiberglass, a dense material, can be difficult to drill into without leaving messy, fractured holes. With the proper tools and techniques, however, you can drill perfect holes where you need them without the help of a professional.
Things You'll Need
- Measuring tape
- China marker
- Power drill
- 11/64-inch drill bit
- Safety glasses

Use a measuring tape to space the holes you need and place them according to the project you are completing.
Mark an X over spots to drill, using a china marker. If you are hanging shelves or caddies, use a level to make sure the hole marks are placed correctly. If the holes are not level, re-measure and mark them again until they are level.
Insert a 11/64-inch drill bit (preferrably carbide- or diamond-tipped) into a power hand drill and tighten with a chuck.
Wear protective safety glasses and place the point of the drill bit into the center of each X. Depress the drill's trigger to start drill through the fiberglass. Keep the drill straight as you drill through to avoid angled holes and torn edges.
