Why Choose a Geberit In-Wall Toilet?
Geberit is the world leader in concealed toilet systems, known for their engineering, design flexibility, and long-term reliability. The Geberit Sigma 8 is one of the most popular models in high-end residential and commercial fit-outs, and for good reason.
Key benefits of in-wall cistern toilets:
- Minimalist, wall-hung design with no visible tank
- Easier to clean and more hygienic
- Dual flush plates for water efficiency
- Compatible with wall-hung or floor-mounted pans
- Quiet operation with concealed plumbing
- Designed for easy servicing via the flush plate
Installed properly, a Geberit in-wall cistern system adds value and elegance to any bathroom, and it’s built to last.

What’s Involved in In-Wall Toilet Installation?
Unlike standard toilets, the plumbing, frame, and cistern are built into the wall cavity, and need to be installed before tiling or wall cladding begins.
Our Geberit in-wall installation service includes:
- Site inspection and pre-install advice
- Cistern and frame installation
- Wall-hung or floor-mounted pan fitting
- Flush plate placement and alignment
- Waste pipe and water line connections
- Full pressure and leak testing
- Certification of compliance
We’ll also coordinate with your builder or tiler to ensure everything is installed at the right stage of your renovation or build.

Geberit Flush Plates and Compatibility
Geberit’s flush plates are customisable and come in a range of finishes, chrome, matte black, white, brushed metal, and even glass. They’re not just aesthetic; they offer dual-flush capability and sit flush against the wall, giving you a completely modern look.
Not sure which model fits your wall cavity or bathroom style? We’ll guide you through your options.
