Frequently Asked Questions

What is a concealed cistern toilet?

These types of toilets hide the water tank (the cistern) inside the wall. That leaves only the toilet pan and flush button visible. It creates a clean and streamlined look while saving space in the bathroom.

Are in-wall cistern toilets harder to install?

Compared to close-coupled or standard back-to-wall toilets, yes, concealed toilet cisterns are harder to install. They require more planning, and they need to be built into the wall cavity with secure brackets and a way to properly access the cistern for future servicing. Concealed cistern toilets are best installed during renovations or new builds.

Can I replace just the flush button plate?

Yes. All Baiachi in-wall cisterns in our range are compatible with interchangeable flush plates. You can switch from round to square designs, or change the finish without replacing the entire cistern.

Do in-wall cisterns meet Australian standards?

All concealed cisterns, flush buttons, and suites at Renolink are Watermark and WELS-certified. This ensures safe operation and compliance with plumbing codes, complete with efficient water usage.

What’s the main advantage of an in-wall cistern toilet?

The biggest benefit is space. By hiding the cistern in the wall, the bathroom looks and feels more open and less cluttered. It’s a smart option for smaller bathrooms, ensuites, and contemporary designs where clean lines are a priority.
