Help & advice
When replacing your toilet, look for highly efficient (HET) or ultra-low flush (ULF) toilets to minimise water use. Dual flush toilets do also reduce water usage however that depends how well you remember which button to press when! You can also buy cistern displacement / water saving devices.
Here we've summarised the practical differences of the four most common toilet types – close coupled, traditional, wall hung, and back to wall.
Most modern toilets are close coupled, where the cistern (the part which holds the water for flushing, located above the toilet bowl) is attached to the toilet in one unit.
The traditional toilet has a separate cistern that sits further up the wall.
A wall hung toilet is attached to the wall where the cistern is concealed behind a wall or unit. The bowl looks like it 'floats' above the floor.
Like wall hung toilets, back to wall toilets are also attached to the wall with the cistern concealed behind a wall or unit. Unlike wall hung toilets, back to wall toilets don't usually need the support of a frame as they rest on the floor.
