Review: Good quality product - Quality product. Installed for instructions and came out great
Review: 28" Kerdi-Board - Customized with 2 Marble shelves 12" apart creating 2 x 12" and 1 x 4" compartments for bathroom storage - Excellent product, easy to use, very flexible to customize - I added two shelves (12", 12" and 4" compartments) using marble 4" wide bullnose cut to proper length to fit tiled box - used decorative 12 x 12" tile sheets made of 1" x 1" decorative tile squares of several different natural stone (slate, marble, ceramic, travertine, glass, granite) cut to fit the 3 compartments that I designed. The 28" long box provides flexibility to create whatever is needed for storage. I chose 2 x 12" high compartments to store my bottles of shampoos and conditioners - I measured my favorite pump bottles with the pump part fully extended and the longest was 11" so the 12" space allows for easy removal and storage - don't forget to take into consideration the thickness of tile you are using to line the front, back and sides and the thickness of the shelf material used when you rough in the dimensions for the shampoo, conditioner, etc... I was left with a 4" shelf compartment for bar soap, razor storage, loofa and whatever other small items you are using in shower (including a new squeegee used for cleaning the new glass shower doors and new wall tile after a shower). Used metal (Oil Rubbed Bronze) tile bullnose to edge out box with rest of bathroom wall tile, and marble 4" bullnose for shelving cut to length (better than the shelf supplied with Keri Box, much thinner and needed more than one shelf) - marble bullnose for shelving was inexpensive and available in stock at Lowes and HomeDepot as was decorative tiles used for the background inside box.

### ⭐⭐⭐⭐⭐ 1 liter bottles fit in the finished shelf, on both shelves
*by M***L on October 12, 2025*

This was the perfect shower niche. Exactly what we were looking for. My husband and I each have our own shelf, and the 1 liter bottles fit in the space provided. We love the Schluter system and how easy it was to install.
