Size, Shape and Proportions
The best size and shape of tiles for your bathroom depends on the overall layout and size of your room. If you’re styling a small bathroom, for instance, bigger tiles usually help to make the space feel larger and more open such as on a bathroom floor or the bathroom walls.
As with most design tips, there’s no hard and fast rules for size and shape of tiles. Instead, look at each of the surfaces that need tiling and determine where focus should be placed and avoided. It is very common to use larger square or rectangle tiles on main areas of the bathroom – ie tile floor and wall and use smaller tiles as points of interest.
Opting for a small mosaic as a feature tile can be great as a shower wall, shower nook or vanity splash. Incorporate the use of shapes into your design by choosing penny rounds or small hexagon mosaics for variety in your room.
Use tiles that draw attention (either by sizes, shapes, textures etc.) to those focus areas of the room: all other tiles should complement these focal points.
