Why are close coupled toilets so popular?

close coupled toilet

To explain why close coupled toilet designs are popular, I’ll first explain what a close coupled toilet is. The close coupled toilet is most likely the type of toilet that you have in your own home; it’s the most common type of toilet these days, the type that has the cistern attached to the actual toilet bowl at the back. Close coupled toilets are so popular these days that you may never have considered an alternative design, but actually there are quite a few nice alternative toilets being used in bathroom design these days.
The reason the close coupled toilet is so popular, however, is that it is the easiest and cheapest to make, and provides great functionality. Before the close coupled toilet was invented, most people had what is known as ‘high level’ toilets. These were the toilets that had the cistern high up above them on the wall to increase flushing power in the days when this was needed. You may remember seeing them in some period properties or hotels you have visited. The high level toilet was quite an attractive design, but it had an unfortunate tendency to drip on the heads of sitters (the dripping was clean water from the cistern, but it was still an unpleasant situation).
This is why as soon as flushes were invented with the power to flush without gravity the close coupled toilet was invented. This kept the cistern nicely hidden, which people liked as the toilet cistern had come to be seen as an eyesore and waste of space (nowadays people enjoy high level toilets as a design feature, but when they were more common this was not a consideration). With the cistern hidden, there was no danger of dripping, and the toilet bowl and cistern came together to be seen as one item in time. Nowadays, when most people think of a toilet, they think of close coupled toilets.
However, many modern bathrooms are now utilising such features as the wall hung toilet, or the hidden cistern design. The wall hung toilet can look quite attractive; it involves the cistern being embedded into the actual wall so that only the toilet bowl shows, and it is fixed onto the wall itself so that it appears to be ‘hanging.’ It is a nice design feature, but it does involve quite substantial renovation and advice from professional plumbers such as dsi-drainage.co.uk in order to have it fitted as the wall itself needs to be reinforced in order to hold the weight of a person.  The Bathroom Store have some great examples.
The hidden cistern design is quite similar to the close coupled toilet, except that the cistern itself is embedded in a piece of fitted bathroom furniture such as a vanity closet. The toilet bowl then appears to hang from this piece of furniture, which is in turn attached to the wall. Again, this can be a nice design feature and a nice alternative to the close coupled toilet. However, both these designs tend to suit only very contemporary bathrooms. For a traditional bathroom design, it’s more appropriate to use either the close coupled or the high level toilet.
