Countertop–to–ceiling backsplash with 45˚ tile and custom border

A full–wall kitchen backsplash. We used 4” x 4” travertine tile, installed at a 45˚ angle with a brick–pattern border. The backsplash was installed on two right–angled walls, which also had a right–angled window. The travertine was sealed prior to installation and re–sealed after the grouting was complete.
