I'm renovating an ensuite and adding a wall-hung vanity. My tiler reckons I should fasten the vanity to the wall (villaboard) before he comes. My plumber reckons the vanity should be installed after the tiling - ie on top of the tiled wall.
I would have though the tiler would come in first and waterproof the area and tile before installing the vanity.
Does anyone know what the usual practise for this is?
