There are many factors to consider when choosing shower tile. The design of the shower dictates the typeof tile to be used. A shower with a curved shower bench needs a small tile. The tile must be suitable for both floor and wall.
Mosaic shower tiles are the most widely chosen for a continuous, clean look that conforms to the pitch of the floor in a shower. Smaller bathroom tiles are perfect for covering a sloping floor. There are enough grout lines to provide traction against slipping.
The choice of tile has to be wet location approved. Ninety-five percent of the tile backside must be in contact with the tile concrete, referred to as the thin set. Frequently, thin set installation involves a notched trowel. Tiles such as mosaic cannot reach 95 percent coverage with trowel thin set installation.
Large format tile is ideal for aging in place and barrier free design. Search for a tile with an A or B slip resistance to address the safety issue of large format tile. That tile is safer than one with a C rating.
