4 - If your favorite color for a bathroom is pink, for example, add a few pink decorative tiles for the walls or use shapes, textures and borders to give it some visual interest. Select some rows of the walls where you can also use some of the pink tiles placed diagonally.
A dark grout might seem different, but so long as you don't look for a grout that is usually so dark this looks black, you ought to be fine.
For tiles which might be not so sleek, you can possibly space the tiles firmly together or leave a smallish gap. A 1/8th-inch gap belongs to the standards used with tiling.
