Caroma Luna Cleanflush Toilets

Caroma Luna Cleanflush toilets combine the Luna range's rounded design with Caroma's rimless Cleanflush bowl technology, meaning there's no rim around the inside of the bowl for waste or bacteria to collect in. The result is a toilet suite that's genuinely easier to keep clean and less prone to the odour buildup that traditional rimmed bowls develop over time.

What Cleanflush actually means

A standard toilet bowl has a rim around the inside edge that directs flush water around the bowl, but that same rim creates a hidden ledge where waste, limescale and bacteria can build up out of sight. Cleanflush removes that rim entirely, so the bowl surface is one continuous, smooth curve from top to bottom. Flush water is redirected through a different channel design instead, so flushing performance isn't sacrificed for the cleaner bowl shape. In practice this means less scrubbing under the rim, fewer odours between cleans, and a bowl that looks cleaner for longer with the same cleaning routine.

Reduced splashback

Because there's no rim interrupting the water surface, Cleanflush bowls also tend to reduce splashback compared to traditional rimmed toilets, since the flush water follows a more direct, controlled path rather than being forced around a rim edge. This is a smaller but real day-to-day benefit, particularly in family bathrooms getting heavy daily use.

Luna Cleanflush toilet suite options

Luna Cleanflush toilets are available as close-coupled suites, where the cistern sits directly on the back of the pan as a single unit, which is the most common configuration for full bathroom renovations and covers the vast majority of standard Australian bathroom layouts. Depending on the specific model, back entry or bottom entry water connection options are available, which matters for matching existing plumbing rough-in points, especially in renovations where you're replacing an older toilet without moving the waste pipe.

Water efficiency

Luna Cleanflush toilets carry a WELS water efficiency rating, and most models in the range sit at a strong star rating for dual-flush water use, which is worth checking on the specific product page since it affects both water bills and, in some states, eligibility for water efficiency rebates on renovation projects. Dual-flush operation lets you choose a lower-volume flush for liquid waste and a full flush for solid waste, which is standard on Australian toilets now but worth confirming the exact litre ratings if you're specifying for a project with water efficiency targets.

Matching the Luna suite

The Luna Cleanflush toilet shares its design language with the rest of the Luna range, including basins and baths, so if you're renovating a full bathroom around the Luna aesthetic, the toilet suite will sit visually consistent with a Luna basin or bath chosen for the same room. It's a smaller, quieter design decision than most people think about during a renovation, but a toilet with a noticeably different design language to the rest of the room's fixtures tends to stand out for the wrong reasons.

Seat and cistern details

Luna Cleanflush toilets are sold with a matching seat, usually a soft-close design that prevents the lid or seat slamming shut, which extends the life of the hinge mechanism and is a genuine quality-of-life detail in a busy household bathroom. The cistern buttons are typically dual-flush plates set into the top of the cistern, finished to match the rest of the suite rather than a separate plastic component that looks bolted on.

Installation notes

Before ordering, confirm whether your bathroom's existing waste outlet is back entry or bottom entry, since this determines which Luna Cleanflush model fits your plumbing without requiring the waste pipe to be relocated. Renovations that keep the existing waste position and swap only the toilet suite are considerably simpler and cheaper than jobs that need the outlet moved, so this is worth checking against the product specifications before purchase, ideally with your plumber.
