Back-to-wall toilets are a clever solution to give the illusion space in a small bathroom while also bringing modern style to create a contemporary look. Traditional styles are also now available if you wanted a sleek alternative to a close coupled toilet for your luxury bathroom design.

The cistern (sold separately) is hidden behind the toilet pan, either within a toilet unit or concealed by a stud wall. If you can't fit it in a stud wall then you might have to build some boxing/false wall or hide in some furniture. If fitted into furniture the cistern flush would normally be a push button, as the top fascia is removable.  However if you are fitting into boxing/false wall, using a flush plate will give easier access to the cistern once fitted. 

Toilet seats are usually Quick release for ease of cleaning and tightening and Soft close toilet seats to reduce noise. The exact seat that in the range  that matches the pan is normally the only option although some shapes (oval and D shaped) are more universal. Contemporary shaped pans usually have a plastic seat whereas traditional ones are commonly wooden.

Close coupled toilets have the ceramic cistern directly attached to the pan, creating one streamlined unit which combines both essential parts.
The choice of open back or closed back pans gives you the option of the pipes being hidden within the casings. if the waste pipe runs out sideways from the toilet you will need open back.

A vast majority of toilet seats nowadays are soft closing, meaning that they are safer to use in a family environment as children won't get their fingers caught underneath the seat. Most seats are also quick release for ease of cleaning and quick access for maintenance including tightening. Most contemporary shaped pans take a plastic seat where as the traditional shapes usually take the wooden seats. You normally have to get the exact seat from the same range as the pan but the oval and D shaped seats are more universal.

A low level toilet is where the toilet cistern and the toilet pan are joined by a short L shaped flush pipe, so that the cistern sits slightly above and behind the bowl. They are a very popular type of toilet in the Traditional designs as they replicate some of the original designs in the UK. The flush pipe can be supplied in a few different finishes such as Brass and Nickel.

These are slightly taller than close coupled toilets so might not be suitable if under a low window. the seats for these tend to be wooden oval shape and can be standard or soft close.

Wall mounted toilets are installed to the wall and are suspended keeping space between the floor and pan, giving the illusion of more floor space and allowing room for easy cleaning underneath.  The cistern is fitted within the wall using a frame, the outlet pipe goes into the wall concealing it along with the cistern.

These frames can be fitted into a wall with a flush plate for maintenance access to the cistern or if you can't fit it in the wall then you could look at boxing out with a false wall. There are also smaller frame models that fit into furniture which can be used with a smaller flush button as the top fascia of the furniture can be removed for access..

A new technology is Rimless which is a rim free bowl in the top inner edge of the pan for easy cleaning and is more hygienic. Also state of the art technology are the Shower toilets which have a bidet function allowing you to wash with warm water and can have features such as air dryer, heated seat, odour extractor, and even automatic opening lid and lighting.

Most tend to be modern styles but there are a few traditional options too.  Toilet seats are usually Quick release for ease of cleaning and tightening and Soft close toilet seats to reduce noise. The exact seat that in the range  that matches the pan is normally the only option although some shapes (oval and D shaped) are more universal. Contemporary shaped pans usually have a plastic seat whereas traditional ones are commonly wooden. 

High level toilets are very much traditional designs based on some of the original designs seen here in this country. Their high cistern is fixed to the wall and connects to the toilet pan via an exposed flush pipe with a pull chain to operate it.

These are very tall although the flush pipe can be adjustable when cut to size so make sure you have enough height in the room. The seats for these tend to be wooden oval shape and can be standard or soft close.
