How To Put a Rubber Liner in a Shower Stall

If you worry all the time about water pooling in your shower stall or springing leaks, there’s now a foolproof method of preventing those nightmares. Instead of the lead shower pan used in a bygone era, rubber liners are now more effectively applied under tiled shower stall floors.

Here’s how to install your own rubber liner in your shower stall.

  • Gather your materials first. You will need a rubber shower liner, a box cutter, a power drill or a drill with a Phillips bit, a hammer, wood screws, galvanized nails, a tube of silicone caulk, a tape measure, and a pencil.
  • Measure the floor of your shower stall. Use a tape measure to yield exact measurements. Add six inches to every measurement on all four sides of the shower stall.
  • On a clean floor, lay out the rubber liner. With a pencil, mark the rubber liner with the dimensions you acquired for the shower stall. Make sure your measurements and markings are correct and exact.
  • Cut the rubber liner. Use a box cutter and cut according to the measurements you took earlier. Make sure it’s a clean cut.
  • Lay the cut rubber liner onto the shower stall floor. Again, use the box cutter, this time to cut a hole over the shower drain.
  • Apply silicone caulk under the lining. Only apply this under the lining that touches the opening of the shower drain. Silicone caulk is a sealant and water-proofing agent with a sticky and gel-like consistency. It is usually clear and colorless. It can bond almost any type of material and fixture both used indoors and outdoors like ceramic, glass, metal, plastic, rubber, and wood. Its primary use is for sealing plumbing fixtures. Silicone caulk is effective because it keeps water from seeping into the space beneath the fixtures, minimizing moisture damage like accumulation of mold and rotting.
  • Fold over the excess lining that extends through the shower entrance. Using the power drill and the screws, secure the lining to the outer side of the shower entrance. Do this using the power drill or the drill with the Phillips bit, and the wood screws.
  • Cut out some notches where necessary. This is to make sure that the whole rubber lining remains flat on the entire surface it covers.
  • Fold the excess lining over the shower stall walls. Smooth the excess lining over the inside walls of the shower stall. Create an overlap on the corners.
  • Smooth and stretch out the lining. Make sure the lining stretches over all four corners of the shower stall. Check for bumps or bunches and smoothen it out again.
  • Secure the lining on the interior walls. Do this using the hammer and the galvanized nails. Again, make sure that the lining remains flat and stationary against the surface.
  • Trim the excess lining. Cut off some excess rubber liner, if there are any left, using the box cutter.

Easy to install and remove when you need to apply repairs, a rubber liner is just the perfect solution to counter and prevent leaking problems in your shower stall.
