OK, should probably have posted this in a plumbing website but thought I'd try you lot first. Having loads of work done on house & have got new bathroom fiitings. Bath now all fitted & tiled, ready to fit new sink which sits on top of a 26mm beech worktop. When the plumber looked at the waste fitting for the tap, discovered it was too short to go through the base of the sink and the worktop (the problem is with the link for the pop-up waste system on the tap). Despite numerous searched on the 'net & through plumbers merchants, they all seem to say that you either - drill large holes in countertop to fit waste through, or fit a 'clicker' style waste. Latter option would mean either having the waste lever at back of tap but not used, or leave it off tap & end up with hole at back (but not very visible). So, question is, for all you people out there with countertop sinks (and they can't be that unusual, surely) how is the waste connected underneath. Changing sinks/taps is not an option as too far down the bathroom design for it
