The Ultimate Guide to Building a Preformed Recessed Shower Niche

In this post we cover:
Situations where you would consider modifications
A technique to check if your foam niche is still waterproof
Method and tools to customize a foam shower niche
Staying out of trouble
Otherwise known as How to Void the Warranty on your Shower Niche
In part 1 and part 2 of this guide, I talk about how to layout and install a foam shower niche. But not everything always goes perfectly. Tile doesn’t always lay out perfectly centered in a stud bay and if it does it may not be the location that you would like. Sometimes you’re close to making it work but not quite.

This post will give you a couple of examples where I’ve made modifications to the niches. It covers why it was done and how I did it.
Please keep in mind that this isn’t recommended and no manufacturer will approve of this process. Proceed at your own risk. :-)
Situation 1: The foam shower niche sticks out past the wall too far
It’s not unusual for the niche to want to stick out slightly from the wall. After all a lot of backer board these days is 7/16 inch- thinner than the niches. In the previous post, I had a photo of a technique that I use to keep the niche in place until it dries.
But sometimes a little bit further customization is in order. That’s where this technique comes in.
I personally have never tried this but it’s mainly because I’ve never thought of doing this. But it’s a clever way to make your foam shower niche work in the space.
Situation 2: The niche needs to move less than one inch
I recently had a project where I wanted to center the tile on the shower faucet. But the problem with this is that the niche wasn’t going fit a row of tile perfectly. In this case, it was about 1/4 inch off. So this meant that the tile would be 1/4 inch off center of the shower faucet. So what did I do?
I cut the end of the foam niche off.
