One popular solution for a bathroom is to create a wet room, which is basically a walk in shower room that is much more comfortable than the enclosed shower types. These can be created to suit virtually any room type as long as a few simple rules are followed. The room will need to be waterproofed (tanked) to provide a seal and water leaking downstairs or next door. The tiles will need to have falls created if they don't already exist in the substrate, to allow the water to drain and the water to not pool in an area.
For something a little bit less drastic, you will discover a tile which has a pattern, but that is certainly also a similar color for the tiles you've currently picked. You can set these patterned tiles in the random fashion, very, so the rooms don't look hence plain.
2 - When using the same color ceramic tile for the floors and walls, choose a different tile size for the walls or lay the wall tiles diagonally to create a more interesting visual effect.
