Rimless Toilets Explained: Are They Worth It?
What Is a Rimless Toilet and Should You Choose One for Your Bathroom?
If you've been shopping for a new toilet, you've probably noticed the word "rimless" appearing more and more often.
But what exactly is a rimless toilet? Is it really easier to clean? Does it flush differently? And, most importantly, is a rimless toilet worth buying?
The simple answer is that rimless toilets remove one of the hardest areas of a conventional toilet to clean: the enclosed rim around the inside of the bowl.
That seemingly small change can make a significant difference to everyday cleaning and hygiene.
In this Allbits guide, we'll explain how rimless toilets work, their advantages and disadvantages, what to look for when buying one, and some of the Roca rimless toilets available from Allbits Plumbing Supplies.
What Is a Rimless Toilet?
A traditional toilet bowl normally has a rim around its upper inside edge.
During flushing, water travels through this enclosed channel and exits through openings beneath the rim.
The problem is that the underside of this rim can be awkward to see and clean.
A rimless toilet removes that traditional enclosed channel.
Instead, the bowl has a much more open internal shape and uses a specially designed water-distribution system to direct the flush around the bowl.
Roca describes its Rimless bowls as having fewer angles and hidden areas, while its water-distribution system spreads the flush around the bowl surface.
Rimless vs Traditional Toilet
Here's the basic difference:
| Feature | Traditional Rimmed Toilet | Rimless Toilet |
|---|---|---|
| Enclosed internal rim | Yes | No traditional enclosed rim |
| Hidden areas beneath rim | More | Fewer |
| Easy access for cleaning | More difficult | Easier |
| Flush distribution | Through rim channel | Purpose-designed distributor |
| Modern designs available | Yes | Yes |
| Close-coupled options | Yes | Yes |
| Wall-hung options | Yes | Yes |
| Back-to-wall options | Yes | Yes |
The biggest advantage isn't that a rimless toilet somehow cleans itself.
You still have to clean it! 😂
The advantage is that there are fewer awkward hidden areas to get into.
Why Are Rimless Toilets Easier to Clean?
This is probably their biggest selling point.
On a traditional toilet, dirt and limescale can collect underneath the rim, where they're difficult to see and awkward to reach with a cloth or brush.
Remove the enclosed rim and much more of the bowl becomes visible and accessible.
That means:
- Fewer hidden areas
- Easier wiping
- Easier inspection
- Less awkward scrubbing beneath a rim
- Simpler everyday maintenance
Roca specifically designed its Rimless technology to remove the internal channel and the nooks where dirt can accumulate.
💡 Big Al's Expert Tip
If easy cleaning is high on your wish list, don't look only for the word rimless. Also look at the outside of the toilet. A rimless bowl combined with a smooth closed-back pan can make both the inside and outside of the toilet easier to keep tidy.
That's going to become quite important when we get to our Roca recommendations.
Are Rimless Toilets More Hygienic?
Their design can certainly make good toilet hygiene easier to maintain.
A traditional rim creates areas that can be difficult to reach during normal cleaning.
A rimless design removes much of that concealed area, making the internal bowl more accessible.
Roca's system also uses a dedicated water distributor designed to spread water around the bowl during flushing.
It would be wrong to claim that simply owning a rimless toilet eliminates bacteria or removes the need for cleaning.
It doesn't.
But the design makes thorough routine cleaning considerably more straightforward.
How Does a Rimless Toilet Flush?
This is where rimless toilets become quite clever.
Removing the traditional rim means manufacturers have to control the flush in another way.
Rather than water travelling through an enclosed channel, a rimless toilet uses a specially designed distribution system to direct water around the exposed bowl.
With Roca Rimless®, water is propelled and distributed around the bowl surface, while a slight upper edge is designed to help contain the water and minimise splashing.
Roca also now offers Rimless Vortex technology on selected products, where water creates a 360-degree swirling action around the bowl.
Do Rimless Toilets Splash?
A properly designed rimless toilet should control the water within the bowl.
This is a reasonable concern because, without the traditional rim, customers sometimes imagine water firing straight over the top!
Thankfully, that's not how they're designed.
For example, Roca incorporates a slight edge at the top of its Rimless bowl to help prevent water escaping during the flush.
Correct installation and suitable cistern settings remain important.
Do Rimless Toilets Use Less Water?
Don't assume that rimless automatically means low water consumption.
Water use depends on the particular toilet and cistern.
Many modern rimless toilets do, however, combine the technology with efficient dual-flush cisterns.
For example, the Roca The Gap Square Rimless Close-Coupled Toilet currently available from Allbits uses a 4/2-litre dual flush, while the Round version is specified with a 4.5/3-litre dual flush.
So when comparing toilets, check the actual flush-volume specification rather than relying on the word rimless alone.
What Are the Advantages of a Rimless Toilet?
1. Easier Cleaning
This is the big one.
Removing the traditional enclosed rim gives you much better access to the bowl.
2. Fewer Hidden Areas
There are fewer awkward spaces where dirt and limescale can accumulate unnoticed.
3. Modern Flushing Technology
Rimless toilets use specifically designed water-distribution systems rather than relying on the old enclosed rim channel.
4. Lots of Styles Are Available
Rimless no longer means choosing one particular style of toilet.
You can find:
- Close-coupled toilets
- Back-to-wall toilets
- Wall-hung toilets
- Compact toilets
- Comfort-height toilets
- Smart toilets
Roca itself offers rimless technology across floor-standing and wall-hung designs and multiple collections.
5. Great for Busy Family Bathrooms
Anything that makes the weekly bathroom clean easier gets a thumbs-up from me.
And I suspect from whoever gets lumbered with cleaning the toilet! 😂
Are There Any Disadvantages?
Rimless toilets have plenty of benefits, but they're not magic.
They Still Need Cleaning
"Rimless" does not mean "self-cleaning".
Regular bathroom cleaning is still required.
Performance Varies Between Products
Not every rimless flushing system is identical.
Choose a reputable manufacturer and check the product specification.
Installation Matters
Incorrect cistern settings or installation can affect flushing performance.
Price
Some rimless models can cost more than basic traditional toilets, although the technology is now available across a much wider range of price points.
Open Back or Closed Back?
Here's another choice worth understanding.
Open-Back Toilet
Part of the pipework remains accessible at the rear of the pan.
This can make installation and future access easier, particularly when replacing an existing toilet.
The Roca Ona Rimless Close-Coupled Pan sold by Allbits is an example of an open-back design.
Closed-Back Toilet
The sides extend back towards the wall, concealing more of the pipework.
This gives a cleaner, more streamlined appearance and reduces exposed areas around the toilet that need cleaning.
The Roca The Gap Round and The Gap Square models available from Allbits are examples of closed-back rimless toilets.
💡 Big Al's Expert Tip
Replacing an older toilet? Don't automatically order a closed-back model because it looks tidier. Check where your existing soil pipe and water supply enter first. Sometimes an open-back pan makes a replacement installation considerably easier.
Are Rimless Toilets Good for Small Bathrooms?
Absolutely — but rimless itself doesn't save space.
What matters is the toilet's projection, meaning how far it extends into the room.
This is where compact rimless models become particularly useful.
For example, the Roca The Gap Square Rimless Closed-Back Close-Coupled Toilet currently listed by Allbits has a compact 600mm projection, making it worth considering for space-conscious bathrooms.
When shopping for a cloakroom or small en-suite, look for the combination of:
- Rimless bowl
- Short projection
- Compact cistern
- Sensible width
- Suitable soil connection
We'll cover this properly in our upcoming:
Best Toilets for Small Bathrooms
and
Toilet Projection Guide
What About Wall-Hung Rimless Toilets?
Now we're getting into the posh end of the porcelain department. 😂
A wall-hung rimless toilet combines two easy-cleaning ideas:
Inside:
The rimless bowl reduces difficult-to-reach internal areas.
Outside:
Because the toilet is suspended above the floor, you can clean underneath it.
The cistern and support frame are concealed behind the wall or suitable furniture.
This creates a very clean, contemporary appearance.
One particularly nice example in the Allbits range is the Roca Inspira Square Rimless Wall-Hung Pan, supplied with a soft-close seat. The current product measures 370 × 560 × 440mm and carries Roca's 25-year manufacturer's guarantee.
We'll compare this type of installation properly in:
Wall-Hung vs Close-Coupled Toilets: Which Is Best?
That's next on our production line.
What About Comfort-Height Rimless Toilets?
You can have both.
Comfort-height toilets raise the seating position, which some users find easier when sitting down and standing up.
For example, Allbits currently stocks the Roca The Gap Round Rimless Comfort Height Closed-Back Close-Coupled Pan, with a 610mm projection.
We'll give comfort-height toilets their own complete guide later in this series.

Before You Buy Checklist
Before ordering a rimless toilet, tick these off:
☐ Measure the available width
☐ Measure the maximum projection
☐ Check your soil-pipe position
☐ Check the water-inlet position
☐ Choose open back or closed back
☐ Decide between close-coupled, back-to-wall or wall-hung
☐ Check whether the cistern is included
☐ Check whether the toilet seat is included
☐ Check whether the seat is soft close
☐ Check the flush volumes
☐ Consider comfort height if required
☐ Check door, vanity and shower-screen clearance
☐ Arrange appropriate installation
💡 Big Al's Expert Tip
When comparing toilet prices online, check exactly what's included. One listing may include the pan, cistern and soft-close seat, while another price may be for the pan alone. Comparing headline prices without checking the package can be very misleading.
Common Rimless Toilet Buying Mistakes
Assuming Rimless Means Compact
It doesn't.
Always check the projection.
Forgetting the Soil Pipe
A beautiful new toilet is no good if it creates a plumbing headache you weren't expecting.
Not Checking What's Included
Pan, cistern, seat, flush button, frame and fittings can be packaged differently.
Choosing Wall-Hung Without Considering the Frame
A wall-hung toilet requires a suitable support frame and concealed cistern arrangement.
Buying on Price Alone
Compare:
- Ceramic quality
- Guarantee
- Seat
- Flush
- Installation requirements
- Spare-part availability
- Manufacturer reputation
Assuming Rimless Means No Cleaning
Nice try. 😂
Sadly, nobody has invented the toilet that cleans the bathroom for you yet.
Frequently Asked Questions
Are Rimless Toilets Better Than Normal Toilets?
For customers who prioritise easy cleaning and fewer concealed areas around the bowl, rimless toilets offer clear advantages.
A good-quality conventional toilet can still perform perfectly well, but rimless technology makes routine cleaning simpler.
Do Rimless Toilets Smell Less?
A rimless design removes concealed areas beneath the traditional rim where dirt can accumulate, which can make thorough cleaning easier.
However, odours can also come from plumbing, traps, seals and general cleaning, so rimless technology alone cannot prevent every cause of bathroom smells.
Are Rimless Toilets More Expensive?
They can be, but rimless technology is now available across many price points.
Allbits currently carries Roca rimless options ranging from relatively accessible close-coupled models through to premium wall-hung designs.
Can You Get Rimless Close-Coupled Toilets?
Yes.
Roca's Andes, Ona and The Gap models provide examples available from Allbits.
Can You Get Rimless Wall-Hung Toilets?
Yes.
The Roca Inspira Square is one example currently available from Allbits.
Can You Get Comfort-Height Rimless Toilets?
Yes.
Roca The Gap Round Comfort Height combines both features.
Are Rimless Toilets Good for Families?
They can be an excellent family-bathroom choice because the accessible bowl design makes routine cleaning straightforward.
Does Rimless Mean Soft Close?
No.
They're separate features.
Rimless describes the toilet bowl and flushing design.
Soft close describes the seat mechanism.
Always check whether a soft-close seat is included.
What Is Roca Rimless?
Roca Rimless® removes the conventional enclosed bowl rim and uses a purpose-designed water distributor to spread the flush around the bowl. Roca says the design improves accessibility for cleaning while its upper bowl edge helps contain the flushing water.
So, Is a Rimless Toilet Worth It?
For most customers buying a new modern toilet, we'd certainly recommend considering one.
The main benefits are straightforward:
- Easier cleaning
- Fewer difficult-to-reach areas
- Modern flushing technology
- Plenty of design choices
- Compact options available
- Close-coupled, back-to-wall and wall-hung choices
- Comfort-height options available
And because rimless toilets are now available at different price levels, the technology is no longer reserved solely for premium bathrooms.
The important thing is to choose the right rimless toilet for your bathroom, rather than simply buying the first product carrying the label.
Measure the space, check the projection and plumbing, decide which installation type you prefer and compare what's actually included.
Then you can enjoy the bit everyone really wants:
a toilet that's less of a pain to clean. 😂
