Although there are a large number of toilet designs on the market these days they all fall into one of four basic types - close coupled, low level, high level and back to wall.
Each design of toilet is suited to a particular situation or style. The close coupled design is now the most common toilet style in the UK, and has a neater look than the low level and high level cisterns that went before it. The back to wall toilet design is even neater it uses a concealed cistern, hidden in a cacase that also conceals all of the pipework.
There is a detailed page on each of the different toilet designs accessed via the menu on the left
