This is not so much a DIY question as a bathroom design one. In my new
partialy-finished bathroom there is a pedestal basin. The wall which it
sits against is just emulsioned with no splashback. If I leave the wall
like that it's not going to take long before it gets splashed with
dirty water and looks horrible. The usual solution is to put a few
tiles on the wall to make a splashback, but I don't really like the
look of that. Does anyone have any clever ideas for how to make that
area wipeable?
