Ensuite with walk in shower

Walk in shower. Customer had already lined and waterproofed the Ensuite.

It's always important to get the walls vertical and straight with no waviness laterally or up and down. Otherwise it means a lot more glue and a lot more time to maintain a straight line and a good look when tiling.

Floors also need to be level. It can mean a much longer and expensive lay if the floor level is going the wrong way.

If it is straight then all I need to do is to drag the glue over with the trowel and lay. Otherwise it gets thicker and deeper and much slower! Time is money.
