Caroma’s Invisi II® 4.5-3L Cistern is a high-quality concealed cistern from one of Australia’s favourite bathroom brands. With Caroma Smartflush water saving technology and Expella’s Odour extraction system pre-installed inside the cistern, this is an eco friendly toilet cistern that eliminates embarrassing toilet odour and the need for air fresheners.

The Odourless by Expella ventilation system comes fully integrated into the Invisi II® cistern, to quietly extract malodorous air from the toilet pan when in use and discreetly send it into the sewer for a fresh and odour free bathroom. The Caroma Invisi II® in-wall cistern keeps pipes and the cistern hidden inside the wall cavity for a clean and streamlined finish. It has an adjustable flush pipe for more flexible installation and can be installed in a standard 90mm metal or timber stud wall.

Combine this cistern with your choice of Caroma floor mount pan and Caroma flush plate (both sold separately) to complement your bathroom design.

The Caroma Invisi II is a standard in-wall cistern with Odourless by Expella pre-installed inside the cistern. The cistern must be installed by a qualified plumber in accordance with AS/NZS 3500. Installation requires the addition of an electrical power source for the Odourless by Expella system. Have a qualified electrician install a general power outlet (GPO) within 3.5 meters of cable length to the toilet. The location of the GPO should allow future access to the 12VDC power transformer.

Expella recommends that the Odourless by Expella system switches on with the Expella PIR Motion Sensor or with the bathroom light, it can also be shared with the exhaust fan switch or by a designated switch depending on your preference.

The Caroma Invisi II In-wall Cistern fits a 90mm wall cavity with 600mm stud spacing. It is suitable for timber studs only with a 90x45mm stud cross section.

The Caroma Invisi II In-Wall Cistern is compatible with Caroma floor mount pans. Check the dimensions of your selected pan for exact final set out heights for the flush and waste pipe, prior to installation. Heights may vary depending on the pan. 

The cistern is compatible with a selection of Caroma flush plates. Check flush plate specs for cistern compatibility before purchasing and installing. 

A full installation manual is provided with the toilet suite and further information can be found on Expella’s website.

All cistern components (inlet valve, flush valve and Odourless by Expella system) are accessible by removing the flush plate. The Odourless by Expella system is secured within an ultrasonically welded ABS plastic case and requires no maintenance. As with all electrical products, access to the adaptor is recommended.

  • Cistern: 20 years
  • Odourless by Expella: 3 years
