Blue green sea sediment sliced pebble tilesThese sea sediment sliced pebble tiles have a incredible array of different blue, green, olive, and rust tones. The rainbow trout mosaic ceramic fish tiles were an excellent choice, as there are far less olive sliced pebbles in the floor. Another fish tile option would be to use my Blue Green Gray trout fish tiles, or Mountain Moss shaped trout tiles to blend more into the slice stones. By using a light grout; as shown, this brings out the beauty of each individual stone. A teal grout color would significantly darken the floor and would lend a deeper water feeling to the shower floor.
