Rimless Toilets
Rimless Toilet — Open Bowl Design, Hygienic & Easy to Clean
A rimless toilet has no inner rim — the curved bowl wall flows straight into the trapway, eliminating the hidden ledges where bacteria, limescale, and waste traditionally accumulate. LANGDENG's rimless toilets use a powerful siphonic flush that spreads water evenly around the open bowl, delivering complete cleaning with just 3L/4.5L dual flush. Every model in our toilet range is rimless — choose from one-piece, wall hung with concealed cistern, or compact yacht-series rimless toilets. Smart bidet electronics standard on all models. CE certified, OEM/ODM available.

Buying Guide
Rimless vs Traditional Rim
Traditional rim toilets hide 70–90% of bowl bacteria and limescale buildup inside the rim channels — even cleaned toilets develop yellow staining over time. Rimless designs eliminate this hiding place entirely. Hygiene is engineered in, not added with chemicals.
Does Rimless Flush as Well?
Yes — often better. Single-jet siphonic flush creates a strong vortex that pulls waste through the trap. Our rimless siphonic flush passes the MaP 1000g standard at just 3L/4.5L dual flush, the lowest water tier in the industry.
Available Form Factors
Every rimless toilet in our catalog is available in three form factors: one-piece floor-mounted, wall-hung with concealed cistern (180mm wall drain), and compact yacht series for small bathrooms. Smart bidet electronics standard across all.
Frequently Asked Questions
What is a rimless toilet?
A rimless toilet eliminates the traditional inner rim that runs around the top of the bowl. Instead of water flowing through hidden channels, a rimless design uses an open bowl with the flush water released from a single visible jet point at the top, spreading down the smooth curved walls. This makes the bowl visibly cleaner and far easier to wipe down.
Are rimless toilets more hygienic?
Yes. Hidden rim channels in conventional toilets harbor 70-90% of bowl bacteria and limescale buildup, which is why even cleaned toilets can develop yellow staining and odor. Rimless toilets remove this hiding place entirely. Combined with LANGDENG's antibacterial glaze and full siphonic flush, rimless is the standard choice for hotels, hospitals, and modern residential bathrooms.
Does a rimless toilet flush as well as a traditional toilet?
Yes — often better. Rimless designs use siphonic flush technology that creates a strong vortex pulling waste through the trap. LANGDENG's rimless siphonic flush at 3L/4.5L dual flush passes the MaP 1000g standard. The open bowl also makes it easy to spot any residue and re-flush if needed, something the closed rim design hides.
Are all LANGDENG toilets rimless?
Yes. Every smart bidet toilet in our catalog — including all one-piece, wall hung, and yacht-series models — is built with the rimless open bowl design. This is our standard, not an option, because we believe hygiene should not be a feature you pay extra for.
