I have a wall-mounted sink in the bathroom that is perfectly fine, but the pipes are obvious underneath and I'd like to disguise them. The room isn't really large enough to include a vanity, although I suppose a small one could be shoved underneath. Is it possible to get a pedestal base (without a bowl) and use it as a sort of cover? How stable would it be just standing up against the wall, or do these need to be attached to something?

Any and all ideas welcome.
