My Buying Guides on Schluter Niche 12×28 Rough Opening
My Quick Take

I like it because it gives me a clean, built-in storage space without needing shelves sticking out of the wall. For me, the key is making sure the rough opening is measured correctly before I buy anything.
What I Looked For Before Buying
The first thing I checked was whether the niche would fit my wall space and tile layout. Since this is a 12×28 rough opening, I needed to confirm the exact dimensions of the framed opening, not just the finished size. I also made sure I understood the wall depth, stud spacing, and whether my shower wall could support the niche installation.
Why I Considered Schluter

I wanted a niche that would help keep shampoo, soap, and other shower items organized while also reducing the chance of water damage behind the wall. In my experience, that combination of function and protection is what makes Schluter worth considering.
Installation Fit and Planning
Before buying, I thought about how the niche would line up with my tile pattern. I learned that planning the niche location early helps avoid awkward cuts and uneven tile lines.

For me, this step is important because even a great niche can become a headache if the wall opening is off by a little.
Material and Waterproofing

Things I Would Double-Check
Before I purchase, I always double-check:
- The rough opening dimensions
- Wall framing requirements
- Tile thickness and finished wall depth
- Waterproofing compatibility
- Placement height for easy use
My Buying Advice
