Kohler Rimless Back to Wall Toilet Suite with Bidet Seat
A premium smart toilet solution combining Kohler's Grande rimless back-to-wall pan with the Englefield Electric Bidet Seat Plus. Designed for Australian bathrooms seeking superior hygiene, effortless cleaning, and spa-level comfort — all in one complete suite.
Rimless Bowl — Hygiene Max Technology
The Grande pan features Kohler's rim-free design, eliminating the concealed inner rim where bacteria and residue typically accumulate — an advantage many traditional bidet and toilet seat combinations without a rimless pan design cannot provide. Water is distributed evenly across the entire bowl surface with every flush, ensuring a thorough and hygienic clean.
The smooth vitreous china interior reduces build-up over time, making day-to-day maintenance significantly easier.
Englefield Electric Bidet Seat Plus
The included Englefield Bidet Seat Plus delivers a full suite of smart hygiene features inspired by japanese bidet innovation: automatic lid open/close via proximity sensor, a self-cleaning stainless-steel wand, hybrid instant warm water heating, and separate front and rear nozzles with adjustable position, temperature, and pressure.
A backlit LCD remote control with wall-mount bracket provides convenient access to all settings from any position beside the toilet.
Advanced Wash Modes & Comfort Settings
Choose from oscillating wash, turbo massage, air bubble wash, and auto/child cleansing modes — each designed to suit different comfort preferences and user needs including the elderly and children.
A heated seat with adjustable temperature levels, warm air dryer, and a powerful carbon filter deodoriser complete the experience for year-round comfort.
S-Trap & P-Trap Rough-In Compatibility
The Grande pan supports standard S-Trap set-out of 90–160mm (with supplied vario pan connector and 20mm offset pan collar) and P-Trap installation at 185mm set-out height — covering the most common Australian plumbing configurations.
Always confirm your existing plumbing set-out and trap type before purchase, particularly when replacing an older installation.
