Tips in Replacing a Corner Shower Base

Filed under: Plumbing Tips — Tags: , , — admin @ 9:27 pm

Mold and rot could rapidly spread in a home due to a leaking shower base. One should consider replacing it before the leak gives you more problems.

Replacing a corner shower base is relatively easy since there are only two walls that encase it. Although it is something that can be done by a person that lack previous DIY experience, anybody who has done a few DIY jobs can easily perform this task.


  • Pry bar
  • Hammer
  • Drain removal tool or needle nose pliers
  • Drill
  • Caulking and caulk gun


  • Using a thin-bladed pry bar and a small hammer, carefully remove the bottom layer of tiles, particularly so if you do not have matching tiles to use as replacement.
  • Unscrew the cover of the drain. Using a tool for drain removal or pliers, unscrew the shower drain from the drain pipe found under the shower tray.
  • Check if the flange of the base is screwed to the walls. If it is, you have to unscrew it.
  • Using a utility knife cut the caulking located over the seam, it is found in the area where the shower pan’s face meets the bathroom floor.
  • Remove the old pan and replace it with a new one.
  • Screw the flanges to the wall.
  • Roll a little bit of plumbers putty into a rope and wrap it around the outer part of the drain opening in the shower base. Insert the drain in the hole and then screw the drain in place. The putty should ooze from around the drain. When the drain is screwed, scrape the putty up, and then replace the drain cover.
  • Caulk the area where the bathroom floor meets the face of the shower pan.
  • Replace the tile you had removed and grout them as soon as the mortar dries up. Finish it up by sealing the grout after 36–48 hours.

Replace leaking shower bases as soon as possible to prevent the possibility of mold infestation in your homes, which could become a serious health threat.
