I have never installed a bathroom, as wherever we have lived has always had a perfectly nice bathroom and there has never been any need to change it.
We have lived in our house for nearly five years. I think the bathroom was probably five years old when we moved in. So, ten years old. It hasn't dated at all. I will do my best to describe it to you:
Large counter top white rectangular sink on a white gloss very wide wall mounted cabinet. The cabinet is about two feet wider than the sink. White bath with bath panel at the side and feet end, with three large light grey squares in it side by side. Large double shower, white shower tray.
Tiling goes on three walls - two of the walls to say about 4 feet high, and then the fuull height of the shoer on the other wall. Tiling is very large, very dark grey, almost slate look plain tiles, in the same pattern as a brickie would brick a house (technical terms!), with little tiles in the same colour (there is no pattern in the bathroom) going vertically in a narrow section in the centre of the shower.
Flooring is oak look amtico.
Enormous white towel rail.
Large mirrored bathroom cabinet above sink.
Geometric print grey and white roller blind.
