Concealed Cisterns

Learn more about concealed cisterns

Concealed cisterns are toilet tank systems fixed behind a wall or within a frame. That leaves the tank hidden and gives a clean finish.

They're also called hidden toilet cisterns, in wall cistern systems or wall mounted cistern tanks. The flush plate sits on the wall surface, usually with a push button or sensor.

They suit new builds and retrofit work. Single and dual flush options are available, including dual flush concealed cistern models for water efficiency.

Typical uses

• Use concealed cisterns when you want a neat bathroom finish and more floor space.

• They're a good fit for new bathroom installations and renovation work.

• They also suit properties where wall space needs to be used well, or where a modern concealed cistern toilet setup is part of the spec.

• Dual flush models can be the right choice where water efficiency matters.

How to choose the right concealed cistern

• Start with the wall depth and available space. Measure the cavity behind the cistern position and check the frame or tank dimensions before you order.

• Choose the flush mechanism. You can go for single or dual flush, with push button, sensor or lever activation depending on the job.

• Check compatibility with the toilet pan as well. Not every cistern suits every pan, so confirm the details before you commit.

• Think about access. You need a clear route for concealed cistern repair and maintenance, usually through a removable panel or inspection hatch.

Before you order

• Confirm the wall type first, whether that's timber stud, blockwork or concrete. That affects framing and the fixing method.

• Check the incoming water supply and pipework against the cistern model you've chosen. Make sure the flush valve and fill mechanism suit the job.

• Measure the cavity carefully, then measure it again. That helps avoid ordering the wrong tank.

• Review the installation instructions and make sure you have the right brackets, adaptors and concealed cistern parts on site.

• Plan access for future repairs as part of the job. A removable panel or inspection hatch makes maintenance easier later on.
