some people i've asked say they' fit what i supply
some say they will supply and fit
i was thinking about finding the sink that i want and then telling them what combo of sink and tap i wanted and they'd be able to get it cheaper due to them being in the trade and/or recommend a better version of said sink/tap combo for our requirements

but the sink is on the worktop in the middle and there is a bit of cupboard underneath that can be moved, no units of the like to get in the way so simple as anything, but the mrs wants someone else to do it as she's seen my diy skills and doesn't want to be without a kitchen sink for a month while something else i chop off grows back again
