What Is A Rimless Toilet? Everything You Need To Know
Rimless toilets have become one of the most requested products in our range — and after years of buying bathroom products for Perth homeowners, I can see exactly why.
Whether you’re planning a full Perth bathroom renovation, replacing an ageing suite, or building new, the shift toward rimless toilet suites is hard to ignore. Cleaner to maintain, more water-efficient, and better looking than traditional designs, they’ve moved from a premium option to the default choice for most of the customers we speak to.
If you’re considering making the switch — or just want to understand what all the fuss is about — this guide covers everything you need to know. How they work, how they compare to standard toilets, what to watch out for, and which rimless toilet suits your bathroom and budget.
What Is a Rimless Toilet?
A rimless toilet is a toilet designed without the traditional inner rim found on standard pans. Rather than water flowing through small holes under the rim, a direct flush system propels water from a rear outlet around the entire bowl surface in a single controlled sweep — leaving no part of the pan unflushed.
From the outside, a rimless toilet looks identical to any other modern suite. The difference is entirely internal. Standard toilets have a concealed rim channel running around the top of the bowl — a hidden ledge that’s almost impossible to clean thoroughly. Rimless toilets eliminate that channel entirely, replacing it with a smooth, open bowl surface that water can reach in full.
It’s a design that’s now the first choice for most Perth bathroom renovations, and increasingly standard in new builds across WA.
How Does a Rimless Toilet Work?
In a standard toilet, water is released from the cistern through dozens of small holes hidden under the rim. It flows downward in a relatively weak, uneven pattern — and critically, it never reaches the underside of the rim itself, which is where bacteria and limescale tend to accumulate.
A rimless toilet works differently. Water is released from a precision-engineered outlet at the rear of the bowl and propelled horizontally in a controlled arc that sweeps the entire inner surface in one motion. Every part of the pan is contacted with each flush.
Because the flow is directed and efficient, less water is needed to achieve a thorough clean — which is why rimless toilets consistently achieve strong WELS ratings. The quality of that flush comes down to the internals: our range uses R&T fittings throughout, which deliver consistent, quiet performance flush after flush.
Rimless Toilets vs Standard Toilets — What’s the Difference?
| Rimless | Standard | |
| Hygiene | No hidden rim — full bowl access every flush | Rim channel harbours bacteria and limescale |
| Ease of cleaning | Smooth, open bowl — easy to clean entirely | Hard-to-reach areas under the rim |
| Water efficiency | WELS 4-star, 4.5L/3L dual flush | Typically 6L+ per flush |
| Price | Marginally higher upfront cost | Slightly cheaper at entry level |
| Appearance | Clean, modern, wall-faced profile | Traditional look, visible rim |
The hygiene difference is the one that matters most to most buyers. The rim channel on a standard toilet is virtually impossible to clean thoroughly — water doesn’t reach it, brushes can’t get under it, and bacteria accumulate in areas that remain untouched between cleans. Perth’s hard water makes this worse, as limescale builds up in the channel over time and becomes increasingly difficult to shift.
Water efficiency is the other standout. Older standard toilets commonly use 6L or more per flush. Our rimless range operates at 4.5L full flush and 3L half flush — a meaningful saving on WA water bills over time, particularly for larger households.
On price, rimless suites do cost a little more upfront, but the gap is smaller than most expect and is offset by long-term water savings and less spend on cleaning products.

The Benefits of Rimless Toilets
Rimless toilets offer four clear advantages over standard suites:
- Superior hygiene — no hidden rim for bacteria and grime to accumulate
- Easier cleaning — full access to the entire bowl surface
- Better water efficiency — WELS 4-star across our range
- Modern design — clean lines that suit contemporary Perth bathrooms
Superior Hygiene
Without a rim channel, there are no hidden surfaces where bacteria, grime, or limescale can build up between cleans. Every flush contacts the full bowl surface, which standard toilets simply can’t match. Some models also feature Nano Glaze — an anti-bacterial coating applied to the inner pan that further resists bacterial adhesion and makes the surface easier to keep clean over time.
Easier to Clean
You can see and reach the entire pan — there’s nothing hiding under a ledge. In practice, a quick once-over with a toilet brush and a mild cleaner is all it takes. I’ve found a sodium percarbonate-based soaker (the active ingredient in products like Napisan) dissolved in warm water and left in the bowl works better than most dedicated toilet cleaners, at a fraction of the cost.
Water Efficiency and Savings
All three rimless suites in our range carry a WELS 4-star rating, operating at 4.5L full flush and 3L half flush. Older single-flush toilets commonly used 9–12L per flush — the difference adds up significantly on a Perth water bill over a year. Water Corporation has consistently pushed water-efficient fixtures for WA households, and a WELS 4-star toilet is well aligned with that.
Modern Design
The wall-faced profile and clean, rimless bowl suit contemporary bathrooms well. They pair naturally with wall-hung vanities, frameless shower screens, and minimalist tapware — without the visual bulk of older close-coupled styles.
Are There Any Disadvantages to Rimless Toilets?
In the interest of giving you a complete picture, there are two drawbacks worth knowing about.
Splashing
This is the one that comes up most often online. Yes, rimless toilets can splash — but in almost every case it’s an installation issue, not a design flaw. The flush flow valve needs to be correctly set during installation; too much water pressure and you’ll get splash, the right setting and you won’t. A quality model, properly installed, should not have this problem. Putting the seat down before flushing also eliminates the risk entirely. We haven’t had this reported by customers for any of the suites we stock.
Price
Rimless suites cost marginally more than comparable standard models. Our range of rimless toilets start from $380 with the Daytona Tornado — which sits comfortably alongside mid-range standard suites from other retailers.
The honest summary: the disadvantages are minor and largely avoidable. The hygiene, cleaning, and water efficiency benefits are real and lasting.
How to Clean a Rimless Toilet
Cleaning is straightforward — without a rim to get under, a toilet brush and standard cleaner is all you need. Run the brush around the smooth bowl surface and you’re done.
For a deeper clean, I use a sodium percarbonate-based soaker — the active ingredient in products like Napisan — dissolved in warm water and left in the bowl for an hour or so. It’s more effective than most dedicated toilet cleaners and considerably cheaper.
If your suite features Nano Glaze, the anti-bacterial coating does a lot of the work between cleans by resisting bacterial adhesion. All three suites in our range also include a quick-release seat, making full removal for a thorough clean a simple, tool-free job.
