Here's an idea beyond painting, wallpapering, or paneling an accent wall -> install tile!
Seriously, why not?!
Its an amazing way to add interest and texture to a wall, like I did here with Zia Tile's Cotto line of modern terra cotta tile. A modern way to bring an earthy element to a room. Especially a memorable guest room for visitors.
It makes sense if you have a small space to add interest too without spending to much money on materials and install labor. Yes, I do recommend hiring professional installers to get it just right. Here is a BTS look.
First, select the tile direction and pattern.
Find your center point and try to include as many whole tiles as possible. Make progress up the wall with spacers.
