Thinking about a sleek, modern loo where the tank is hidden away in the wall? That’s a concealed cistern — and it’s one of the most popular upgrades we help customers with at our Petts Wood counter. In this guide we’ll explain what a concealed cistern is, how it compares to a traditional close-coupled toilet, and how to choose the right one for your bathroom.
What is a concealed cistern?
A concealed cistern is the water tank that sits behind the wall or inside a furniture unit, rather than bolted to the back of the pan where you can see it. All you see in the room is the pan and a neat flush plate. It’s the setup you’ll find behind most wall-hung and back-to-wall toilets, and it’s a big part of that clean, contemporary look.
You’ll usually pair a cistern with a wall-hung toilet frame (which takes the weight and hides the pipework) or a back-to-wall unit. Browse our full range of concealed cisterns to see what we stock.
Concealed vs close-coupled: which is right for you?
A close-coupled toilet has the cistern sitting directly on the pan — simple, reliable and quick to fit. A concealed cistern hides everything for a minimalist finish. Here’s the short version:
- Concealed — sleek looks, easier to clean around, frees up floor space (especially wall-hung). Costs a little more and needs access for maintenance.
- Close-coupled — cheaper, dead easy to install and service, but the cistern is on show.
Dual flush and saving water
Almost every concealed cistern we sell is dual flush — a smaller flush for liquids and a full flush for solids — which can save a serious amount of water over a year. Our Alpha Concealed Cistern (Dual Flush) is a popular, well-priced choice that fits standard frames and back-to-wall pans.
How to choose the right concealed cistern
- Mounting — wall-hung (needs a frame fixed to a solid or reinforced wall) or back-to-wall (sits on the floor against the wall).
- Flush plate — pick a finish you like (chrome, white, matt black). Check it matches the cistern’s fixing.
- Access — the flush plate is your service hatch, so make sure the valve inside is easy to reach if it ever needs attention.
- Height & rough-in — frames are adjustable, but plan your pipe and waste positions before you tile.
A quick word on fitting
Concealed cisterns are best fitted before tiling, as the pipework and frame go in first and the wall is built out around them. If you’re confident with a first-fix it’s a satisfying job; if not, any decent bathroom fitter will have done dozens. Either way, we’re happy to talk through the parts you’ll need.
