Rimless Toilets Buying Guide
The enclosed rim on a traditional toilet pan hides a channel that directs flush water around the bowl, but that same channel is difficult to clean thoroughly, since it sits out of reach of a standard toilet brush. A rimless design removes that hidden channel entirely, directing water around the bowl's open surface instead, so every part of the bowl is both flushed and reachable for cleaning.
How rimless flushing works
Rather than water flowing downward from beneath a rim, a rimless toilet directs water around the bowl's edge at a specific pressure and angle, calculated to clean the full surface without excessive splashing. Because there's no hidden channel for the water to pass through, the flush reaches areas a traditional rimmed pan can leave partially covered.
Why choose a rimless toilet?
Hygiene is the main advantage. Without an enclosed rim, there's no recessed space for bacteria, grime or residue to collect out of reach, which makes a rimless bowl noticeably easier to clean thoroughly rather than just superficially. This is a genuine practical benefit for households with young children or elderly family members, where a consistently clean toilet matters more than in a low-traffic setting.
Water efficiency follows from the same design. Many rimless toilets pair the open flush design with a dual-flush system, offering a full flush for solid waste and a reduced half-flush for liquid waste, conserving water without a reduction in flushing performance.
Design is the third consideration. A rimless bowl has a cleaner, more minimal silhouette than a traditional rimmed pan, without a visible lip breaking up its shape. This suits contemporary bathroom design generally, and works particularly well in smaller bathrooms and ensuites, where the compact, streamlined shape of a rimless toilet helps the room feel less visually cluttered than a bulkier traditional suite would.
Choosing the right rimless toilet
A few practical factors are worth working through before selecting a specific model:
- Bathroom size and layout rimless toilets are available in a range of sizes and pan shapes, from compact models suited to small bathrooms through to larger designs for more spacious rooms
- Flushing system dual-flush systems suit households wanting to conserve water, while a single-flush system may suit a higher-traffic bathroom where flush consistency matters more than water saving
- Installation type wall-hung toilets have a concealed cistern and no floor-mounted base, giving a minimalist look and simplifying floor cleaning; floor-mounted toilets are generally more straightforward to install and provide robust, stable support
- Existing plumbing compatibility confirm the new toilet suits the existing plumbing setup before purchase, or consult a professional installer to check compatibility
Waste trap type
Most rimless toilets in this collection use a universal trap, meaning they can be installed in either an S-trap or P-trap configuration without needing a different toilet model for each. If it's unclear which trap type an existing toilet uses, a plumber can confirm this, or a photo of the current installation can be sent to The Blue Space's team for a compatibility check.
Water inlet type
Inlet location can generally be matched to suit the existing bathroom setup. A bottom inlet (BI) enters at the base of the cistern, typically connected via a flexible hose or moulded copper pipe, and is more common in older homes. A back entry (BE) inlet is concealed at the top rear of the cistern, giving a slightly tidier appearance where that inlet type is already in place.
Brands in this collection
This collection includes rimless toilets from Caroma, Bao Bath, Indigo, Seima, Fienza, Studio Bagno and Decina, across both wall-hung and floor-mounted configurations.
Can I replace my existing toilet with a rimless one?
In most cases, yes. Confirming trap type and water inlet compatibility with the existing plumbing beforehand, or consulting a professional installer, helps ensure a straightforward replacement without unexpected plumbing changes.
Are rimless toilets suitable for a small bathroom?
Yes. Their compact, streamlined shape suits small bathrooms and ensuites particularly well, helping the room feel less visually cluttered than a bulkier traditional toilet suite.
Considering a smart toilet or bidet?
For a further step up in hygiene and functionality, The Blue Space's Smart Toilets and Bidets collection covers toilets with additional features such as heated seats, integrated washing functions and automatic lids, alongside the same rimless bowl design covered in this collection.
