Should tile be at the top or bottom of a shower wall?

Plan the Layout



The goal is to maximize the size of tiles at the bottom and top, avoiding narrow pieces. I avoid using a full piece at the top because the ceiling is usually not perfectly level. By cutting the top course of tile on all three walls, I can keep the joint width consistent all the way around.

Can I tile myself?

Bottom Line. Laying tile is easy but laying tile and doing it well is difficult. From that angle, it may make more sense to hire a professional tiler than to do it yourself. If you’re trying to save money, one way to approach it is to hire the pro for the most visible areas.

Is it cheaper to tile a shower or buy a surround?

Custom-tile showers are usually considerably more expensive than prefabricated shower units, although luxury-end prefabricated showers come close in cost. Tile shower pans are difficult to construct, and installation becomes much easier if you start with a factory shower pan and then tile the walls.
