Close Coupled Bathroom Toilet

Now the most popular type of bathroom toilet, the close coupled pan and cistern hide more pipework than low or high level toilets.



The cistern is bolted directly onto the toilet pan to form a single unit, which can have disadvantages if the bathroom soil pipe is positioned in the floor - see our bathroom design section for more details.

Because regulations have been introduced to make new bathroom toilets flush with less water, cisterns can now be made much narrower than previously which has lead to some very compact designs being made available. These regulation changes also allow the use of new flushing mechanisms which are generally quieter in operation than the old syphons and work at the push of a button.

The downside of these new regulations is that the flushing performance of new bathroom toilets can be slightly inferior to older models that have larger cisterns.

Most bathroom toilet designs now available in the UK do not require an external overflow making installation quicker, easier and neater. Previously a pipe would have to be run from the underside of the toilet cistern and run through the bathroom to an outside wall (if the valve started to leak, water would overflow into this pipe and would be seen a drip from end of the pipe where it protruded through the wall.
