It really does depend but after having just bought these items ourselves I can give you some idea ... for something like the Shires Napoli suite (toilet and sink, no taps) we were quoted €220 approx. from Chadwicks and for more expensive we got a toilet from Vogue bathrooms for €340 and a sink for €160 (again, no taps). Tubs and Tiles have a sale on till 16th Feb on their suites, I think it's their own brand stuff though.
