All About Concealed Cisterns: What You Need to Know


When it comes to bathroom design, sometimes it's the things you can't see that make all the difference. Enter concealed cisterns – the unsung heroes of modern bathrooms. But what exactly are they?

Concealed cisterns are plumbing fixtures hidden behind walls or within cabinetry that hold the water necessary for flushing toilets. Unlike traditional exposed cisterns, these sleek marvels remain out of sight, contributing to a clean and minimalist aesthetic.

The benefits of opting for concealed cisterns are as clear as the water they hold. Not only do they save space, but they also elevate the visual appeal of any bathroom. With their hidden placement, they offer more freedom in bathroom design, allowing for cleaner lines and more creative layouts.

Types of Concealed Cisterns

Let's dive deeper into the world of concealed cisterns and explore the different types available:

  1. In-wall Concealed Cisterns:

In-wall cisterns are installed within the wall cavity, completely hidden from view. This type is perfect for achieving a seamless and minimalist look in your bathroom. Imagine a toilet that appears to float effortlessly, with no visible plumbing in sight – that's the magic of in-wall concealed cisterns.

  1. Under-counter Concealed Cisterns:

For those who prefer a vanity or cabinet-mounted sink, under-counter concealed cisterns are the way to go. These cisterns are installed beneath the countertop, maximizing space while maintaining a clean and uncluttered appearance.

  1. Ceiling-mounted Concealed Cisterns:

Ceiling-mounted concealed cisterns offer a unique solution for bathrooms where wall space is limited or where a floor-mounted toilet is preferred. By mounting the cistern above, it frees up valuable floor and wall space, providing more flexibility in bathroom design.


Components of a Concealed Cistern

Before we jump into the installation process, let's get acquainted with the essential components that make up a concealed cistern:

Flush Plate: This is the stylish face of your concealed cistern, allowing you to trigger the flush with a simple press or touch.

Flush Valve: The unsung hero behind the scenes, responsible for releasing the water from the cistern to initiate the flush.

Water Inlet Valve: This valve controls the flow of water into the cistern, ensuring optimal refill after each flush.

Overflow Pipe: A safety feature that prevents overfilling of the cistern by diverting excess water to the drainage system.

Mounting Frame: The backbone of your concealed cistern, providing stability and support when installed within the wall or counter.


Installation Process of Concealed Cisterns

Installing a concealed cistern may seem like a daunting task, but fear not! With the right guidance and a sprinkle of DIY spirit, you'll have your bathroom upgraded in no time. Here's a simplified rundown of the installation process:

Preparing the Wall or Counter: Measure twice, cut once! Ensure that the designated space within the wall or counter is adequately prepared to accommodate the cistern and mounting frame.

Mounting the Frame: Think of it as assembling a puzzle – carefully mount the frame within the designated space, ensuring it's level and securely fixed.

Installing the Cistern and Plumbing Connections: With the frame in place, it's time to slot in the cistern and connect the plumbing. Double-check for any potential leaks and tighten those connections for a watertight seal.

Attaching the Flush Plate: The cherry on top! Affix the flush plate to the wall or counter, adding a touch of elegance to your bathroom decor.

Testing for Leaks: Last but not least, put your installation to the test! Flush away any doubts by running a thorough check for leaks and ensuring everything operates smoothly.

Regular cleaning of flush plate

The flush plate is not just a button; it's the gateway to a refreshing flush. Keeping it clean ensures smooth operation and prevents any unsightly buildup.

Checking for leaks and drips

Even the tiniest leak can lead to big problems over time. Periodically inspect your concealed toilet cistern for any signs of drips or leaks to nip potential issues in the bud.
