Using Larger Drain To Repair Cracked Shower Pan
Updated 10/23/2025 | Published 09/21/2025
Question:
Hi all, I have a 2013 3150RL Keystone Montana 5th wheel with a neo-angle shower. The drain has a small crack around it about 1/16” away from drain assembly. I was looking at your part LaSalle Bristol RV Shower Drain w/ Grid Strainer - 1-7/8 Diameter - Parchment Part Number: 34465PR227G. Could I just make the pan hole a touch larger to get rid of the crack and use this drain without replacing the entire shower pan? It might not be in the molded beveled pan edge if I use this larger drain. What do you guys suggest? It seems like the white board insulation under the pan is compressed too much, not giving the support for the pan. A inch or more around the drain has no support around it so obviously it was made to crack in a sense. Honest opinions would be appreciated. Thank you, Brad Z.

Hello Brad, thanks for reaching out. If you are able to enlarge the drain hole, installing a slightly larger drain like the # 34465PR227G is a good solution for this. That way you can get rid of the crack without replacing the whole shower pan. The drain not sitting on the beveled pan edge shouldn't be a big deal as long as everything is properly installed and sealed. It is pretty typical for there to be a lack of support under RV shower pans so the only advice I can offer for that is to tread carefully and try not to step on the drain.
