Shelving and Niches
Shelving and niches are the perfect answer for that extra storage space you may need in your shower area, since it is convenient, functional and it doesn’t take up any space in your shower. A good location for the shower niche is on a wall opposite or adjacent to the shower head.
Shower Niche Sizes

- Shower niche depth: 2.5 inches minimum to 3.5 inches maximum

An alternative to using a shower niche is to install a shower ledge. This is generally a half-height wall that protrudes several inches and allows room to sit shampoo, conditioner, and soap.
When renovating your bathroom, it is often practical to have your shower installed where your current shower is; rather than moving your shower’s location. You will need a good contractor and shower door installer to achieve favorable results.
