Caroma Smart Toilets and Bidet Seats Buying Guide


Caroma smart toilets and bidet seats add warm-water washing to the bathroom. This collection includes two Urbane II wall faced bidet suites, a close coupled model and an Invisi Series II model, plus the Caroma electronic bidet seat for selected existing Caroma pans. They suit households that want better hygiene, comfort and less reliance on toilet paper.

What is the difference between a bidet suite and a bidet seat?

A bidet suite is a complete toilet designed around the electronic seat, so the pan, cistern and seat are matched from the start. A bidet seat replaces the standard seat on a compatible pan you already have. A suite suits a new build or full renovation, while a seat suits an upgrade without replacing the toilet.

What are the Urbane II bidet suites like?

Both Urbane II suites have a Cleanflush rimless pan, a seat with GermGard antimicrobial protection and a 4 star WELS rating with a 4.5 litre full flush and a 3 litre half flush. The close coupled suite stands 838mm high, with a 440mm pan height, 700mm projection, 383mm width and a 225mm set out. The Invisi Series II suite has a 440mm pan height, 570mm projection and 370mm width, with a universal trap and an S-trap set out of 60 to 135mm or a P-trap set out of 185mm.

Will the Caroma bidet seat fit my toilet?

The Caroma electronic bidet seat fits a listed selection of Caroma pans, including Luna, Luna Slim, Urbane, Urbane II and Liano suites and their Invisi II versions. Check your exact pan model against Caroma's compatibility list before ordering.

What features does the bidet seat have?

A remote control adjusts water and air temperature, water flow and nozzle position. The remote uses two CR2032 batteries, not included. The seat has an IPX4 water resistance rating and a heated tank that warms the wash water to 31 to 39°C. It is not compliant with AS 1428.1 accessible or ambulant requirements, so it is not suited to an accessible fit-out.

What do I need to install a smart toilet?

You need a cold water connection and a general purpose power outlet near the toilet, ideally installed before tiling. The water supply must have backflow protection, and the Caroma seat meets this with an integrated air gap tested to AS 2845.2 and a dual check valve. Installation must be done by a licensed plumber and electrician to AS/NZS 3500.2.

How do I clean a bidet seat?

Wipe the seat and lid with a soft cloth and mild soapy water, then dry. Avoid abrasive and solvent cleaners on the plastic. Use the nozzle self-clean function regularly and check or replace the water filter as described in the manual.

Frequently Asked Questions

What are the disadvantages of a smart toilet or bidet seat?

The main trade-offs are upfront cost, the need for a nearby power point, and slightly more that can go wrong compared to a fully mechanical toilet, since electronic components, wash nozzles and heating elements all add complexity. Some people also find the learning curve of remote or panel controls takes a little getting used to. For a bathroom without an existing GPO near the toilet, adding one is an extra electrical job to budget for before installation.

Do you still need toilet paper if you have a smart toilet or bidet seat?

Most people still use a small amount of toilet paper or a designated cloth to pat dry after the wash cycle, even though the seat itself does the cleaning. Some seats include a warm air dryer function that reduces this further, but it's not universal across every model. The realistic outcome is significantly less paper use, not zero.

Is it worth buying a smart toilet or bidet seat in an Australian bathroom?

It comes down to priorities rather than a universal yes or no. The hygiene and comfort benefits are real and well established, wash-based cleaning is standard in much of Europe and Asia for good reason, but the cost and installation requirement (a nearby GPO, plus standard plumbing) are higher than a standard toilet. It tends to make most sense in a main ensuite or a renovation where the electrical work is already being planned, rather than as a retrofit into a finished bathroom.

What's the difference between a bidet seat and a full smart toilet suite?

A bidet seat replaces just the seat on an existing pan and adds wash functions, which is the less invasive option if the current toilet is otherwise fine. A full smart toilet suite replaces the entire pan and cistern with an integrated unit built around the electronic features from the ground up, usually with a wider range of functions and a more integrated appearance than a seat-only upgrade.

Do smart toilets and bidet seats need special electrical work?

Yes, they need a GPO within reach of the toilet position, and Australian wiring rules require that power point to be positioned outside the bathroom's designated water splash zones. This has to be installed by a licensed electrician, and it's far easier to plan during a renovation before walls are closed up than to add afterwards. It's worth confirming GPO placement with your electrician and plumber together before ordering.

What features actually matter when comparing Caroma smart toilets and bidet seats?

Beyond the basic wash function, look at whether the seat has adjustable water temperature and pressure, a heated seat, a warm air dryer, and a self-cleaning nozzle, since that last feature affects ongoing hygiene of the unit itself. Also check the water inlet requirements against your existing plumbing before ordering, some models have specific pressure or supply requirements that a plumber should verify first.
