My plumber favours close coupled or back to wall toilet suites that can be repaired easily. Can anyone suggest a simple streamlined design for a toilet that has an easily accessible cistern, flushes in one go, ie half and full flush get rid of waste properly. My plumbing requires an S trap, set out wall to centre 130 - 140mm and back entry. I am interested in brands where spare parts are easy to get, ideally universal fittings and seats replaceable etc. Have looked at Porcher (Reece house brand) and Caroma styles such as Opal but some forums report leaking problems.
