Installation of wall hung toilets is a little more problematic than with standard back to wall toilets, so it is best to seek the advice of First Call Plumbers because when installing a wall hung toilet a special bracing frame needs to be used inside the WC unit, which also houses the concealed cistern.

Wall hung toilets were initially designed for commercial applications but have become increasingly popular in domestic situations as design influences have changed, and people have looked to maximise the space they have available. They tend to be more expensive than other toilet designs.
