Caroma Toilet Parts Buying Guide


This collection holds genuine Caroma replacement and upgrade parts: cistern flush buttons, Invisi Series II flush plates, toilet seats and seat hinge caps. They let you refresh the finish of an existing Caroma toilet or replace a worn part without changing the whole suite.

How do I know which Caroma part fits my toilet?

Start by identifying the toilet range and cistern type. Caroma parts are matched to specific ranges, so a Luna button fits Luna suites only, and seat hinge caps are made for particular seat families. Look for the range name on the cistern lid, under the seat or in your original paperwork, and note whether the cistern sits on the pan, is concealed in the wall with an Invisi Series II plate, or uses an older pneumatic system. Measuring the existing part also helps.

What flush buttons and plates are available?

For close coupled cisterns, there are round metal cistern flush buttons in brushed brass, brushed nickel, matte black and gunmetal, and Luna round cistern buttons in brushed brass, brushed nickel and satin black. For in-wall cisterns, the Invisi Series II plates come in round, oval and rectangular shapes. The round plate is 210 x 110mm and 5.5mm thick with concealed fixings, and comes in brushed brass, brushed nickel, matte black, gunmetal, white and neutral.

Can I change the colour of my flush button?

Yes. Swapping a chrome button for brushed brass, brushed nickel, matte black or gunmetal is a simple way to match the toilet to new tapware. Choose the button made for your range, as buttons are not interchangeable between every cistern. The Invisi Series II plates fit Caroma's Invisi Series II in-wall cisterns.

What are seat hinge caps?

Hinge caps are the small covers that sit over the seat hinges. Changing them lets you match the hinges to your flush button and tapware without replacing the seat. There are two sets: one for Urbane, Contura and Riviere seats, and one for Liano, Arc and Xena seats, in finishes including brushed brass, matte black, gunmetal and stainless steel.

Which replacement Caroma seats are available?

The collection includes the Xena soft close seat, the Liano soft close seat in white and the Caroma Family D Shape seat with GermGard. The Family seat includes a built-in child seat and comes with a compatibility list for Caroma pans across the Luna, Urbane, Urbane II, Elvire and Liano ranges. Caroma seats use quick release stainless steel hinges, so they lift off for cleaning.

Can I fit Caroma parts myself?

Many can be fitted at home. Cistern buttons, hinge caps and seats fit with simple tools, following the instructions supplied. Invisi Series II plates clip onto the in-wall frame once the old plate is removed. Jobs inside the cistern, such as replacing an outlet valve, adjusting the water level or fixing a pneumatic system, are best left to a licensed plumber. To clean buttons, plates and seats, wipe with warm soapy water and avoid abrasive or harsh chemical cleaners.

Frequently Asked Questions

At what height should a toilet roll holder be installed?

The standard installation height for a toilet roll holder in Australia is approximately 650–700mm from the finished floor level, positioned to the side of the toilet at a comfortable reach. It should be installed 200–300mm in front of the toilet bowl. Always follow any specific recommendations from the manufacturer.

What type of toilet roll holder is best for a bathroom?

Toilet roll holders are available as recessed wall-mounted, surface-mounted (open arm or enclosed), and freestanding floor-standing options. Surface-mounted open arm holders are the most common in Australian bathrooms, they allow easy one-handed roll change. Recessed holders give a very clean, built-in look and suit minimalist bathrooms. Choose a holder in a finish that matches your other bathroom accessories for a coordinated result.

How do I match bathroom accessories to my tapware?

The simplest approach is to buy your accessories from the same brand range as your tapware, many brands such as Phoenix, Caroma Urbane II, and Meir offer coordinated tap and accessory collections. If mixing brands, focus on matching the finish (e.g. brushed nickel or matte black) rather than the exact product range. Small variations in tone between brands are often barely noticeable in a finished bathroom.

What is the most popular finish for bathroom accessories in Australia?

Matte black has been the dominant finish for bathroom accessories in Australia for the past several years and remains very popular. Brushed nickel, brushed gold, and brushed brass are also strong choices for warmer or more luxurious interiors. Chrome remains the most versatile and classic option. For coastal homes, PVD-finished accessories offer the best long-term corrosion resistance.

What bathroom accessories do I need for a complete bathroom?

A fully equipped bathroom typically includes a towel rail or heated towel rail, a toilet roll holder, a robe hook (or hooks), a soap dish or soap dispenser, and a toothbrush holder. In the shower, a shower shelf or niche is essential. For a cohesive look, choose all accessories from the same range and finish, most Australian accessory brands like Nero, Phoenix, Meir and Caroma offer complete coordinating sets.

How do I identify which Caroma toilet model I have before ordering parts?

Check inside the cistern lid first: Caroma stamps a model name or code on the underside of the lid or on the inlet valve body on most suites made in the last 15 to 20 years. If that's worn off, the pan shape and button style (single, dual-flush round, or dual-flush rectangular) can narrow it down, but the safest option is to photograph the cistern with the lid off and check it against Caroma's model finder, or bring the old part in for a physical match. Ordering by pan shape alone isn't reliable, several Caroma ranges share very similar external profiles but use different internal mechanisms.

Where can I buy genuine Caroma replacement parts in Australia?

Genuine Caroma parts are sold through authorised retailers and plumbing suppliers rather than generic hardware alternatives. Buying genuine matters more for cisterns than for cosmetic items, because inlet valves, outlet valves and flush mechanisms are engineered to specific tolerances for that model's water-saving flush volumes. A part that looks similar but isn't the genuine fit can leak, flush poorly, or fail to seal properly against the pan.

What's the most common reason a Caroma toilet starts leaking or running continuously?

A continuously running cistern is almost always the inlet valve (fill valve) or the outlet valve seal wearing out, both are wear items that harden or degrade with age and mineral buildup in the water supply. A leak at the base of the pan usually points to a failed connector or a worn pan collar rather than the cistern itself. In both cases, matching the replacement part to the exact model prevents a repeat failure, a slightly wrong seal size will often leak again within months even if it appears to fit.

Can I replace Caroma toilet parts myself or do I need a plumber?

Straightforward items like a flush button, a toilet seat, or an inlet valve can often be swapped by a confident DIYer once the water supply is isolated. Anything involving the outlet valve, the pan connector, or work that requires disconnecting the cistern from the wall or floor should go to a licensed plumber, both for safety and because plumbing work on a fixed water connection generally needs to meet Australian plumbing regulations. If in doubt, isolate the water and get a professional opinion before attempting a repair.

Are Caroma toilet seats considered a spare part or a separate purchase?

Seats are sold and fitted separately from cistern and valve parts, and they need to match the pan shape rather than the cistern mechanism. For seat-specific sizing and hinge-fit guidance, see the dedicated Caroma toilet seats range rather than treating it as a cistern part.

Will a universal or generic part fit my Caroma toilet?

Sometimes, for simple items like a generic seat or a basic inlet valve, but fit and finish vary enough between brands that it's not a safe assumption for anything sealing against water pressure. Cistern buttons, flush valves and pan connectors are usually brand and model specific because Caroma designs its flush mechanisms around particular water-saving volumes tied to WELS ratings. Checking compatibility against the specific model before buying avoids a part that technically fits but leaks or under-flushes.
