Invisi Series II Range

Caroma Invisi Series II is a concealed cistern toilet system where the cistern sits hidden behind the wall and only the flush button is visible on the wall face above the toilet suite. It suits bathrooms and powder rooms where a clean, streamlined look is the priority, since removing the visible cistern frees up space around the toilet and gives the wall a much simpler appearance.

How the Invisi Series II system works

Instead of the usual close coupled or back to wall toilet with the cistern sitting in full view, Invisi Series II hides the cistern inside the wall cavity or a purpose built frame, with only a slim flush button showing on the finished wall. The toilet pan itself connects to this concealed cistern rather than to a visible tank, so the overall footprint of the toilet is smaller and the space reads as tidier, particularly in compact ensuites and powder rooms where every centimetre of visible fixture counts.

What the collection includes

The range covers both the concealed toilet buttons and the toilets designed to work with the Invisi Series II system, so a full concealed cistern toilet suite can be sourced from the one collection. Choosing the button and the toilet pan together helps make sure the flush mechanism and pan are correctly matched, since concealed systems rely on the button, cistern and pan all working as one coordinated unit rather than being mixed with unrelated toilet suites.

Choosing a flush button

The flush button is the only visible part of the cistern once installed, so it becomes a small but noticeable design detail on the bathroom wall. Buttons in this range are typically available in more than one finish, so it is worth checking the button finish against your tapware and other bathroom fittings to keep the overall palette consistent, since the button will sit at eye level on a feature wall rather than tucked away like a traditional cistern lid.

Choosing the toilet pan

The toilet pans built for the Invisi Series II system are designed specifically to pair with the concealed cistern, so they should be selected together with the button and cistern frame rather than matched to a separate toilet suite. Pan shape and height are worth considering against the rest of your bathroom fixtures, particularly if you are matching the toilet to an existing basin or vanity in the same space.

Why choose a concealed cistern system

• A cleaner wall line, with no visible cistern tank taking up space behind the toilet
• More usable floor and wall space in small bathrooms, ensuites and powder rooms
• A discreet flush button as the only visible cistern component
• A coordinated toilet pan and cistern system designed to work together

Installation considerations

Because the cistern sits inside the wall rather than on top of the pan, installing an Invisi Series II system generally needs to be planned early in a renovation or new build, since it requires a stud wall cavity or a dedicated in-wall frame to house the concealed cistern before tiling and wall sheeting go on. This makes it better suited to full bathroom renovations or new builds than a simple toilet swap, and it is worth discussing wall cavity requirements with your builder or plumber before committing to the layout.

Buying tips

Start by confirming the wall structure in your bathroom can accommodate a concealed cistern frame, then choose the toilet pan and flush button together from the Invisi Series II range so the whole system is matched. If finish consistency matters for your bathroom, check the button finish against your tapware and any other exposed hardware in the room before finalising the order.
