When planning your tile layout, think color and pattern and coordinate the whole room, floors, furniture, walls, accessories. Consider your whole design scheme at the same time. The more powerful your tiling decor is, the more restrained your other elements should be.This is a good time to consider how thick or thin, how dominant or restrained you want your joints and grout lines to be. Unless you want joints to be a dominant part of your pattern, they should be as tight as possible, with no grout lines, or use light-colored grout.
Assess the size and scale of your tile, its individual design and the overall pattern – as well as your layout – within the context of your room.
