Just because you’ve got a plethora of tiles to choose from at your local tile shop doesn’t mean you can use any and all of them in your shower.
Due to the very high amount of moisture, only certain tiles can work in the shower. Couple that with the need for skid resistance (for the shower floor pan) and you’ve got a number of factors to satisfy before you can find the right type of shower tile.
Best Shower Tile Material
For showers, you’re looking for any type of glazed ceramic or porcelain tile. “Vitreous” means that water absorbs into the surface of the tile very relucatantly–if at all. So, with truly glazed, vitreous tile, the surface is completely waterproof, and the grout seams are the only potentially non-vitreous area you will need to worry about. Not to worry, though, grout lines can be sealed.
What About Slate For the Shower Floor?
Slate looks great, and can be used to some degree on shower walls. But slate and other non-vitreous natural stones will need to be sealed. Never use these materials for shower floor pans.
But if you’re dead-set on slate in your shower, use tile that looks like slate. These are regular waterproof porcelain or ceramic tiles that tile manufacturers have mimicked to look just like slate.
The Best Size of Shower Floor Tile
In addition to the composition noted above, shower floor tile works best in smaller sizes.
- Large Tiles – Large tiles such as 12″x12″ or even larger (16″x16″) are the absolute worst for shower floor tile. They are slippery and, to put it frankly, they look weird on shower pans. That’s because you will only be able to fit 4-8 of these large tiles on the shower pan, and this causes the eye to note the grid pattern. Not only that, this necessitates lots of cutting of tiles.
- Medium Tiles – Medium tiles such as 4″x4″ or 6″x8″ can be used. As noted above, the smaller the better. But the best of all are…
- Mosaic Tiles – Mosaic tiles are excellent on shower floors for two reasons. First, they create lots of grouted seams, which provide great slip resistance under your bare feet. Second, these smaller tiles allow you to better form the tiles to the slope in the shower pan, needed to drain water.
