What' Included? - 500 x 215mm Concealed Cistern Unit - Concealed Cistern - Bordeaux Back to Wall Toilet Soft Close Seat - All Fixings Reduced Depth Unit Space in our bathrooms is usually at a premium but that doesn t mean you have to compromise on function or style. Our reduced depth units are designed to be slimmer than the norm but with all the great features and looks you d expect from a full-sized version. After all a bathroom is somewhere you want to relax, not somewhere you feel shoehorned in. Back to Wall Design A lot of modern toilets are rounded at the back which can highlight the pipework in and out of the pan and cistern. They serve a purpose but they aren t the most aesthetically pleasing to look at. That s where you need a back to wall toilet pan! They push right.
