Shower Tile

Use porcelain for most showers. Its water absorption is 0.5% or less, it usually goes unsealed, and it is made both as matte floor tile and as big wall panels. Glazed ceramic is fine on shower walls. Stone can work too, provided you seal it and keep acidic cleaners away from marble, limestone and travertine. On the floor, choose mosaics or small tiles for grip.

Choose floor tile whose wet DCOF reaches 0.42 or more, measured under ANSI A326.3; that is the line drawn for level indoor floors that get wet. Treat it as a minimum, not a guarantee. A matte or textured finish and smaller tiles with more grout lines add grip that the number alone does not show. Polished tile is slippery when wet, so keep it on the walls.

In most showers, yes. Walls only have to shed water, so glossy ceramic, glass or large porcelain panels all work there. The floor has to grip and drain, so its tile should be matte or textured, carry a DCOF of 0.42 or more and be small enough to bend with the 1/4 inch per foot slope. That split also lets you spend more on the wall tile people see first.

Squeegee after each shower and use a pH-neutral tile cleaner once a week. Rinse well, because leftover soap film is what dulls tile and darkens grout. Keep vinegar and other acids off marble, limestone and travertine, which etch. Sealing cement grout slows staining; epoxy grout resists it from the start and needs no sealer.

Run one large porcelain tile on the walls, then switch to a matching mosaic on the floor, so the shower reads as one surface with grip where it counts. A linear drain at the back wall lets a curbless walk-in floor slope one way and take larger tile. Save the contrasting or patterned tile for the niche.

Start with the pan and waterproofing, not the tile. The floor needs a fall of 1/4 inch per foot toward the drain, walls get a waterproofing membrane or sealed backer, and the niche is framed and sealed. Then lay out each wall from a level line so cuts land in corners, set with thinset, and grout once it has cured.
