Bathroom Floor

The tiler turned up today which was a very welcome surprise. He came to lay a slip ? I think thats what it's called? over the floor. It's purpose is to get the fall on the floor going towards the relevant drains. If that had been done properly in our old bathroom we probably wouldn't have had so much trouble with whiteants. If this photo is fuzzy let me know and i'll get on a computer with a better screen and change it.
Just after they left a guy turned up to measure for the security doors. Yay for another step along the way!
