Close to completing a refurb of a cloakroom and I have to build in a cupboard under the sink. Simple enough, although everything has to be a custom fit for good reasons. I want to effectively set the sink into a worktop, although it's not as deep as the sink itself IFYSWIM, more like a curved triangle each side. My original intention was to make this from a piece of white worktop but when we went to get some over the weekend, all the 'white' worktops looked pretty off-white compared with the sink and would look pretty poor. SWMBO says it must be white, so no contrasting colour options there (!).
Plan B is to use something (thick ply/mdf/pine) to make it up, then get a suitable finish onto that. Trouble is, what sort of finish? Regular paint is too weak, things like formica don't seem to be available any more (except in 8x4 sheets to special order). I thought of ceramic tiles but cutting all the curved edges to follow the sink would be a complete pain and (more importantly) doomed to failure in my hands. I don't mind taking a little while getting the job right and it occurred to me that spray paints should be capable of giving a good glossy hard finish if it's built up with plenty of coats but I've only ever used sprays on metal before and have no idea if any will work well on a primed wood surface.
So what does the committee think? Any advice on the spray approach or any other suggestions warmly received...
