Bathroom Flooring Tile - Here’s a procedure to help with layout and installation of ceramic bathroom tiles. As with all projects, good planning and preparation are the keys to success. Be sure to repair all high and low spots on the surfaces to be tiled. Take your time and get this part right. You’ll be pleased with the professional looking results.


First, determine if your tub or shower drain pan are level. Then draw the horizontal working lines. Be sure they are straight, level, and easy to see.

Level Tub or Shower Pan - If the tub is level to within 1/8″, measure and mark your horizontal line from the high point of the tub. The 1/8″ difference (if there is a difference) can be hidden with grout. Measure up from the lip of the tub, the width of a tile plus 1/8″. Make a line using a level and a straight edge, along the back wall and the two end walls.

Out of Level Tub or Shower Pan - If the tub is not level to 1/8″, mark your horizontal line from the low point. Determine a level line just like for a level tub and run a batten along the bottom of the line. It is usually best to nail a straight wooden batten so that the top of the batten is set to the horizontal line. This provides a level surface for the tile. After all the tile is laid, remove the batten and install the bottom row. You will have to cut the bottom row of tiles to fit along the uneven top edge of the tub or pan.
