Buildmat's Guide to Caroma CleanFlush Toilets (And Which One We Recommend the Most)

If you're renovating a bathroom in Australia, there's a very high chance a Caroma toilet is on your shortlist. Caroma's an Australian institution, and their CleanFlush technology is currently the benchmark for rimless toilets.

But when renovators start searching online for Caroma CleanFlush toilets, they usually hit a roadblock. They see the Caroma Luna toilets, the Caroma Urbane II toilets, the Caroma Liano II toilets, and the Caroma Contura II toilets sitting side by side. They see terms like "Back Entry", "Invisi Series II", and "Easy Height". They all say "CleanFlush", they all look modern, but the prices and subtle design details vary wildly.

We see these suites installed in real homes, we handle the technical questions from plumbers, and we hear the feedback from homeowners after they've lived with them for six months. In this guide, we explain exactly what Caroma CleanFlush is, how it works, and the real differences between every collection so you can make the right call for your bathroom.

What Is Caroma CleanFlush and How Does It Work?

Before we compare the models, we need to answer the most common question we get: what is Caroma CleanFlush, and is it just marketing jargon for a rimless toilet?

The short answer is no. While all CleanFlush toilets are rimless, not all rimless toilets are CleanFlush.

Traditional toilets have a closed rim around the top of the bowl. When you flush, water pours out of small holes under that rim. The problem is that you can't see or easily clean under there, making it a perfect breeding ground for bacteria and grime.

A standard rimless toilet simply removes that rim and shoots a jet of water around the exposed bowl. It's easier to clean, but cheap rimless toilets often suffer from splashback, where the water pressure forces droplets out of the bowl onto the floor or seat.

Caroma CleanFlush is a patented, Australian designed system that solves this. It combines three specific design features:

1. A completely rimless bowl so there's nowhere for germs to hide.
2. A controlled flow splitter at the back of the bowl that divides the water precisely, sending it in two directions around the bowl.
3. A unique drop zone and bowl profile that controls the water energy, delivering a powerful, whole bowl wash without the splashback issues common to generic rimless designs.

Does it actually work? Yes. Plumbers rate it highly, and the feedback we get from customers is that it truly reduces the amount of time they spend scrubbing the toilet.

Caroma Luna CleanFlush: The Everyday Bathroom Essential

The Caroma Luna range is arguably the most popular bathroom collection in Australia right now. The Caroma Luna CleanFlush toilet suite is the anchor of that collection.

Design and Profile

The standard Luna features a classic, soft D-shape design. It's modern but safe, meaning it won't look dated in five years. The pan height is 395mm, which is a standard, comfortable height for most adults and children. The pan projection (how far it sticks out from the wall) is 670mm.

What We See in Practice

The Luna's the ultimate everyday bathroom essential. It's reliable, it uses the exact same patented CleanFlush technology as the more expensive models, and it's priced very competitively. We sell this suite constantly for family bathrooms, investment properties, and secondary ensuites.

In terms of Caroma Luna CleanFlush specs, the key numbers to know are a 395mm pan height, 670mm pan projection, 4 Star WELS rating (4.5L full flush / 3L half flush), and a universal trap for both S and P trap installations. We get asked about the Caroma Luna CleanFlush review experience regularly, and the consistent feedback is that the flush is powerful, the bowl stays clean, and the quick release seat makes cleaning easy. The same is true for the Caroma Urbane II CleanFlush review feedback we hear from customers: the Easy Height pan and GermGard glaze are the two features they mention most often as genuine upgrades they'd choose again.

Best for: Family bathrooms, budget conscious renovations, and anyone who wants the hygiene benefits of CleanFlush without paying a premium for architectural styling.

Caroma Urbane II CleanFlush: The Premium Upgrade

The Caroma Urbane II range is where Caroma steps into premium, architectural territory. The Caroma Urbane II CleanFlush toilet suite is a significant step up in both design and features.

Pictured: Caroma Urbane II CleanFlush – from $689 

Design and Profile

Visually, the Urbane II is sharper and more contemporary than the Luna. It's got a slightly more structured, low profile look that suits high end, modern bathrooms perfectly.

Crucially, it's an "Easy Height" design. The pan height is 440mm, which is 45mm taller than the Luna. This makes a massive difference for taller adults, the elderly, or anyone with restricted mobility. It's much easier to sit down on and stand up from. The pan projection's slightly shorter at 655mm, making it a great choice for compact spaces too.

The GermGard Advantage

The biggest technical difference, aside from the height, is that the Urbane II features Caroma's GermGard technology. It's a unique antimicrobial formula baked directly into the glaze of the bowl and incorporated into the seat. It actively kills a minimum of 99% of the bacteria it comes into contact with. When you combine GermGard with the rimless CleanFlush design, you're looking at one of the most hygienic toilets on the market.

Customisable Flush Buttons

If you're particular about your bathroom finishes, this is the feature that usually seals the deal. The Urbane II lets you swap out the standard chrome flush buttons and seat hinge caps for coloured options. You can match your flush plates perfectly to your Caroma tapware in finishes like matte black, brushed brass, brushed nickel, and gunmetal.

Specs at a Glance

For those researching Caroma Urbane II CleanFlush specs, the key numbers are a 440mm Easy Height pan, 655mm projection, GermGard glaze, and WELS 4 Star rating. It's available as a Caroma Urbane II CleanFlush wall faced toilet suite in both back entry and bottom inlet configurations, and also as a Caroma Urbane II CleanFlush back entry suite for specific plumbing set-outs. The original Caroma Urbane CleanFlush (first generation) is also still available and shares many of the same design principles.

The Bidet Option

For the ultimate in hygiene, the Urbane II range also includes the Caroma Urbane II CleanFlush bidet. If you're looking for a smart toilet experience, the Caroma Urbane II bidet CleanFlush integrates seamlessly with the rest of the collection.

Best for: Master ensuites, architectural builds, users who need a taller seat, and anyone who wants their flush buttons to perfectly match their tapware.

Caroma Liano II CleanFlush: The Sleek Minimalist

The Caroma Liano II range is built around thin edges, sleek profiles, and a highly contemporary aesthetic.

Design and Profile

The Caroma Liano CleanFlush wall faced toilet suite is visually distinct from both the Luna and the Urbane II. It has a very slim, refined profile that pairs beautifully with the thin-rimmed Liano II basins.

Depending on the specific model you choose, the pan height sits at either 395mm for the standard, or 435mm for the Caroma Liano CleanFlush Easy Height model. The Caroma Liano CleanFlush Easy Height wall faced toilet suite is the most popular Liano toilet we sell, as the extra height suits a wide range of users. It's also slightly more compact in its projection, making it excellent for tight spaces.

Features

Like the Urbane II, the Liano II includes the GermGard antimicrobial glaze for maximum hygiene. It also features a premium, thin-profile soft close seat that perfectly complements the minimalist aesthetic of the pan.

Best for: Minimalist bathrooms, tight spaces, and anyone building a bathroom around the thin-edged Liano II basins and tapware.

Caroma Contura II CleanFlush: The Sculptural Statement

The Caroma Contura II range is Caroma's top tier, luxury collection. It's defined by organic, sculptural forms and premium finishes.

Pictured: Caroma Contura II CleanFlush - from $905

Design and Profile

The Contura II CleanFlush toilet is a design statement. It features beautiful, organic curves that feel softer and more luxurious than the sharper lines of the Urbane II. It's an Easy Height design (440mm pan height) and has a compact 655mm projection.

Features and Finishes

This is where the Contura II really stands out. Not only does it include GermGard and CleanFlush technology, but the suite itself is available in premium matte finishes. The Caroma Contura II CleanFlush is the only toilet in the Caroma residential lineup that offers a Matte Clay finish. While the other models are gloss white, the Contura II can be ordered in Matte White or Matte Clay, allowing you to create a truly bespoke, high-end look. It also features the option to colour match the flush buttons to your tapware.

Best for: Luxury architectural builds, high-end master ensuites, and anyone who wants a matte finish or clay-coloured toilet to match a specific interior design vision.

Caroma Care CleanFlush: Accessible and Ambulant Options

For commercial spaces, accessible bathrooms, or homes designed for aging in place, the Caroma Care range incorporates CleanFlush technology into compliant designs.

• Caroma Care 800 CleanFlush: The Caroma Care 800 CleanFlush wall faced suite features an extended 800mm pan projection to comply with AS1428.1 wheelchair access requirements. It sits at a raised height of 430mm-480mm (depending on the seat) and includes a backrest option.
• Caroma Care 660 Ambulant CleanFlush: Designed for ambulant users (those with restricted mobility who do not require a wheelchair), the Care 660 sits at an Easy Height of 435mm with a standard 655mm projection.

The Invisi Series II Option

If you want a truly seamless, minimalist look, almost all of these models—including the Caroma Luna CleanFlush Invisi Series II wall faced toilet suite, the Caroma Urbane II CleanFlush Invisi Series II, and the Caroma Liano CleanFlush Invisi Series II—are available in this format.

The Caroma Invisi Series II range hides the cistern completely inside the wall, in the ceiling, or under a counter, leaving only the pan and the flush buttons visible.

Which One Is Worth The Money?

This is the question we answer every day in the Buildmat Selection Centre. If your primary goal is simply to get a toilet that flushes brilliantly and is easy to clean, the Luna's all you need. It uses the exact same water delivery system as the luxury models. You're not sacrificing flushing performance by choosing the more affordable model.

However, we'd recommend stepping up to the Urbane II, Liano II, or Contura II if any of the following apply to you:

1. You want the extra height. The 440mm Easy Height pans on the Urbane II, Forma, and Contura II make a substantial difference. If you're tall, or if you're renovating a "forever home" that you plan to age in, the Easy Height pan is worth every cent.
2. Hygiene is your absolute top priority. The combination of the CleanFlush bowl and the GermGard antimicrobial glaze on the premium models makes them incredibly sanitary. It's the right call for households with young children or elderly residents.
3. You want to match your tapware. If you're spending good money on brushed brass or gunmetal tapware, a standard chrome flush button breaks the visual flow. The Urbane II and Contura II solve this completely.
4. You want a specific aesthetic. If you're building a minimalist space, the thin lines of the Liano II are perfect. If you're building a luxury, organic space, the matte finishes of the Contura II are unmatched.

Completing the Look

Whether you choose the Luna, Urbane II, Liano II, or Contura II, the beauty of buying Caroma is that you can build out your entire bathroom from the same collection for a perfectly cohesive look.

If you go with the Luna, you can pair it seamlessly with a Caroma Luna basin, a Caroma Luna bath, and the highly popular Caroma Luna II tapware range.

If you opt for the Urbane II, you can elevate the whole room with a Caroma Urbane II bath and match your custom flush buttons directly to your Caroma shower taps and Caroma bathroom accessories.

For the Liano II, the thin-edged Caroma Liano II basins and the stunning Caroma Liano II Brushed Bronze or Gunmetal tapware create a flawless modern look.

And for the ultimate luxury finish, pair the Contura II toilet with a sculptural Caroma Contura II bath and a matching Caroma Contura II basin.
