Used some of the good old pebble tiles on the base of the shower. The pebbles mould particularly well to the slight gradient in the shower floor, which is needed for drainage.
The pebbles also provide a great non-slip surface
still can't quite comprehend it's only a few weeks to go til the house will be ready
even more scary perhaps is the fact that my 3 kids finish school for the summer tomorrow at noon, so much to do with kids in tow!!
