How To Replace an RV Shower Pan

If you’re going camping, on vacation or just about anywhere with your recreational vehicle, you’re in for a lot of fun. Recreational vehicles offer everything you need to enjoy a memorable and exciting vacation — showers, fully-functioning kitchens, living areas, storage quarters, you name it. What happens when you run into problems on the road, though? If your shower pan starts to leak, for example, and you’re in the middle of nowhere, you have to know how to repair it.

RV Shower Pan — Repairing Guide

If you run into problems unprepared, life on the open road will quickly become frustrating. Appliance problems can happen anytime and are not easy to deal with, especially considering that older shower pans tend to develop holes and cracks. They can lead to water damage and harmful mold in your camper as well. Of course, when on the road, the chances of having access to an RV dealer or repair shop and deal with this problem professionally are slim, so you will have to deal with the issue yourself. Provided that you have all the necessary supplies, you can save quite a bit of money as well.

Here are the things that are required to repair a shower pan: soft cloth, acetone, paper towel, utility knife, long-sleeve shirt, mask, gloves, fiberglass paste and fine-grit sand paper.


  1. Put on your mask, protective clothing and gloves and start examining the RV shower pan for problems (look for any sections that are leaking).
  2. Using a utility knife, carve out a “v-notch” along the crack so that it can hold the filler. To do this, take your utility knife, position it to the left or right of the crack, and shape the side of it into a 45-degree slant. Repeat for the other side as well.
  3. Clean the crack using a paper towel, sand the spot gently and clean again. Next, clean using acetone and a soft cloth.
  4. Prepare the fiberglass paste according to the instructions on the label and apply a thin, even coat on the crack. One thing that you should keep in mind, however, is that the mixture hardens quickly, so you’ll need to work fast.
  5. Let it dry for about an hour. If you want to speed the process, you can use a hairdryer.
  6. Lastly, blend the area with the surrounding surface by sanding it lightly with your fine-grit sand paper.

As a general rule, it’s best to repair your shower pan only if you can’t replace it. To avoid running into this kind of problems ever again, be sure replace your old shower pan with a new one. There are a lot of great models out there.
