You typically want to start your bathroom tile installation in the back corner. But if you just start tiling from the back corner, your most visible areas will not line up as planned. Instead, carefully layout the floor tiles with the tile spacers in between them.

When tiling a bathroom where do you start floor or walls?

Whilst you can tile either one first, popular opinion based on experience is that is is easier to tile the walls first and then the floor, if you are tiling both in a room. This ensures that you keep the floor tiles cleaner as you won't be doing so much work around them once they are installed.

Do you start at the bottom when tiling?

A batten board helps you start your bottom-most course or row of tiles. A batten board is usually a 1x4 or 1x2 board screwed directly into the wall. The batten board should be horizontal and level. Do not start the batten board on the floor.
