Are Back to Wall Toilets a Good Idea?
Back to wall toilets offer a sleek, modern design that maximizes bathroom space and simplifies maintenance. In this blog post, we explore the pros and cons of back to wall...

Tornado Rimless Flush
The Tornado rimless ultra quiet flush delivers powerful cleaning performance while operating silently. The rimless design eliminates the concealed inner rim where residue can accumulate, allowing improved water distribution and easier cleaning access.

Matt Black/White – Two Finishes, One Statement
Available in matt black and matt white, the Koko suits a wide range of bathroom palettes — from dark, dramatic schemes to light, minimal interiors. Both finishes carry a smooth, non-reflective surface that resists water spots and fingerprints, keeping the toilet looking clean between wipes.

P-Trap & S-Trap Options
This toilet suite supports common Australian plumbing configurations, available in P-Trap (wall outlet) and S-Trap (floor outlet) formats to match your existing set-out. Both the matt black and matt white finishes are fully available in P-Trap (180mm roughing-in) as well as S-Trap configurations (90-160mm and 160-230mm). Always confirm your plumbing type and set-out measurement before purchasing, particularly when replacing an existing installation.

UF Quick Release, Soft Close Slim Seat
The Koko comes fitted with a UF soft-close seat that prevents slamming and reduces noise in daily use. The quick-release hinge allows the seat to be removed in seconds for thorough cleaning around the hinge area. Please note that seat style varies by colour — the matt black is paired with a Slim UF seat for a sleek, low-profile look, while the matt white comes with a Standard UF seat. Both share the same soft-close and quick-release functionality.
