We bought an unfinished barn conversion having one lidless/seatless toilet of a rectangular shape. The bowl didn't have a name on it and our local builders' merchants (Jewsons, Jacksons, etc..) all said it would be quicker to buy a complete new toilet than try and find a matching seat. Surfing, we found the BetterBathrooms site where there appeared to be one of the correct shape. A 'mail, quickly answered, gave the exact dimensions so we took a chance and ordered one. At the listed price, not all the world if it didn't fit or was not the correct colour. It fits perfectly and colour-matches exactly! Just what we wanted, and delivered quickly too. If only all suppliers provided the same level of service!
