Adding a Shower Niche

Both full -size tile and mosaic are appropriate for the in-shower shelf. Which you choose is a matter of both personal taste and how intricate your niche is. 

Mosaic tile navigates the detailed shower shelf more easily than larger tile. But the larger tile gives a more streamlined look to the simpler tiled shower niche. 

A shower niche should generally be no wider than the studs that framed the shower wall. Often, studs for a shower wall are no wider than 16 inches apart. Twelve inches wide is the perfect width to keep all your products stowed. 

For height, you have fewer limitations. You can make your shower shelf as tall as you like. Add multiple shelves with a tall niche or accommodate for taller items you’d like to keep on the shelf.
