Toilet Suite Designs are divided into three main arrangements:-
The Flush Pipe Suite:
The water gets into the pan through a flush pipe, which is visible, and enters the pan from the rear.
The flush pipe suite is popular for period bathrooms because
it is reminiscent of the old style look.
It also has a very important application in the replacement
market because of the flexibility of being able to position
the pan to suit an existing sewer pipe position in the floor.
By cutting the flush pipe, pan positions of between
130-200mm from the wall can be accommodated.
The Close Coupled Suite:
Here the cistern is positioned directly onto the rear of the pan. This gives the impression that the cistern and pan are one piece with no visible joining pipe. The cistern discharges water directly into the pan via integrated channels cast into the pan during manufacture. The effect is a neat compact appearance which has made possible the development of many creative designs.
Close coupled suites require exact positioning of the sewer
pipe in the floor because there is only minor adjustment
possible between the cistern and pan – they are effectively
The Remote Cistern:
In the case of limited space or for
design considerations cisterns have been developed
that are concealed from view or remote from the pan.
Concealed cisterns can be positioned inside vanities, behind walls or even in the cavity of a stud wall. It is now even possible to position cisterns in ceilings with remote flush controls. These arrangements are naturally more costly than conventional suites.
Level Toilet Suites:
Reproduction toilet suites with high level cisterns are popular in period bathrooms. Cisterns are either of porcelain and visible or of plastic and hidden behind a timber box. Brass or chrome chains are available with porcelain or brass pulls.
The long flush pipe is also in brass or chrome and the
cistern is supported by appropriate ornate brackets.
These units are quite charming and usually take up a
little less floor space due to the absence of the cistern
at body level.
Choosing a Toilet Suite
There are two main considerations in selecting a toilet suite:-
The toilet must physically fit the space and layout.
The colour and design must be appropriate and in keeping with the theme . and decor of the bathroom.
If the toilet is to be positioned over an existing sewer pipe it is important to know the distance of the wall from the centre of the pipe in the floor, see dimension 'A' in figure 1.
In the case of a new bathroom it is important to choose the toilet before the plumbing is started. In the case of close couple suited it is imperative that the toilet is chosen first.
The space required for a Toilet Suite
People often ask for a toilet that extends a minimum distance off the wall. It is obvious that the human body has a relatively fixed geometry which determines the physical size of the unit.
The distance to the tip of the pan from the wall is fairly inflexible around the 650mm mark. A comfortable left to right space for body and elbow room is 800-900mm and the minimum is 700mm. The space required from knees to the back wall is about 950mm.
