In-wall cisterns are now the go-to choice for a good looking toilet suite. They’ve almost become the norm in public and private bathrooms around the world. But if this popular trend hasn’t yet convinced you, perhaps you need more answers?

We’re here to help.

How do in-wall cisterns work? Are they expensive? And, with all the technology hidden behind the wall, are they a pain to maintain? We delve into some of the biggest questions surrounding in-wall toilet cisterns, with help from bathroom renovation specialist, Prince, from InDesign Interior Renovations.

What are the key benefits of an in-wall cistern versus a standard toilet suite?

In-wall cisterns have obvious aesthetic benefits: they look less bulky, come in different finishes and styles, and allow for extra space in your bathroom. But it’s not just about looks; they also come with significant functional and practical benefits:

  • Inwall cisterns allow for flexibility of toilet pan placement because you can place the button at your preferred height.
  • Cleaning of an inwall cistern itself is much simpler because you don’t need to clean around the bulky exterior of a standard toilet suite.
  • An inwall cistern is a bit quieter than a regular suite due to part of the function being enclosed behind the wall.
  • They’re probably more durable than you think; in-wall cisterns have been around for a while now, and the technology has been perfected (Hideaway+ cisterns are made from a high density impact resistant material and the frame can hold 400kg of weight).

What’s one of the biggest things to consider when choosing to install an in-wall cistern?

The most important consideration for an in-wall cistern is the available space behind your wall. Most cisterns require 90mm depth behind the wall to install, your builder or plumber can advise how much space you have as well as how much you need for your chosen product.

If your existing wall does not have the depth required, it is still possible to enjoy the many benefits of a hidden cistern. You will need to create that extra space – which requires a bit more work and a slightly bigger budget. 

Important side fact: Many people believe an in-wall cistern needs to be paired with a wall-hung pan, but you can opt to have a floor mounted pan instead.

Is installing an in-wall cistern better for a big bathroom renovation, or can it be part of a smaller scale bathroom update?

It’s better to install an in-wall cistern as part of a complete bathroom renovation or during the initial build. In most cases, it does require more work than a standard suite. But, always check with your builder because it might be less work than you imagine; it all depends on the layout and walls of your current bathroom.

Is an in-wall cistern hard to maintain?

This is the biggest misconception out there! In the past, in-wall cisterns were clumsy and low quality – requiring additional access panels and big ledges.

You can now get in-wall cisterns which can be maintained and fixed through the single access button.If you choose a quality in-wall cistern brand like Hideaway+ or Geberit, you won’t run into the same maintenance issues of some other inferior brands. With technology-based products, it doesn’t pay to cut costs – do your research and select the best.

Is an in-wall cistern expensive? 

Another common misconception. In-wall cisterns are not as expensive as people think, with improved technology affording a lot more variety and choice. Prices for Reece’s Hideaway+ In-wall Cisterns begin at $300. 

Which type of bathroom suits an in-wall cistern?

In-wall cisterns don’t discriminate – they can blend seamlessly into any bathroom style, but will always work wonders in a smaller space. They’re also great for a family bathroom with children because they’re easier to keep clean and less prone to damage from any rocking or movement.
