Yet another example of mosiac tile in a bathroom is this black white and gray selection that is elevated by a bright pink shower mat. The busy pattern continues through the grout lines, creating a completely seamless look, minus the very faint ending of each tile that is practically unnoticeable. This is an easy transitional design if you’re looking to update your shower floor without ripping out the subfloor as these tiles can be installed directly on top of old linoleum or tile.
