Kohler Grande Rimless Dual Flush Back to Wall Toilet Suite
The Kohler Grande is a back-to-wall toilet suite engineered around rim-free technology — eliminating the hidden inner rim where bacteria and limescale accumulate in traditional toilets. Designed for Australian bathrooms that prioritise hygiene, effortless cleaning, and a refined, contemporary aesthetic.
Hygiene Max Rimless Pan — No Hidden Rim, No Hidden Bacteria
The Grande's rimless bowl design removes the concealed inner rim found in conventional toilets — the primary zone where bacteria, limescale, and residue build up over time. Water is distributed evenly across the entire bowl surface with every flush, ensuring a thorough, hygienic clean that is impossible to achieve with a traditional rimmed pan.
The smooth vitreous china interior minimises surface build-up and makes day-to-day cleaning fast and effortless — no tools, no scrubbing hard-to-reach areas.
WELS 4 Star Dual Flush — 4.5L / 3L
The Grande cistern delivers a WELS 4-star rated dual flush system at 4.5L full flush and 3L half flush, with an average flush volume of 3.5L. This places it among the most water-efficient toilet suites available in Australia, helping households reduce water consumption without compromising flush performance.
The ultra-efficient flush system works in combination with the rimless pan geometry to ensure complete bowl coverage at lower water volumes — a meaningful long-term saving for any household.
Three Seat Configurations to Suit Every Bathroom
The Grande suite is available with three seat options to match your comfort preferences and bathroom specification. The Elite Seat includes a built-in LED night-light and scent dispenser for a premium, spa-like experience. The Slim Seat offers a quiet-close, vertical quick-release slim profile for a sleek, low-profile look. The Wrap Over Seat provides a quiet-close, vertical quick-release standard seat for everyday reliability.
All seats are designed for tool-free removal, making thorough cleaning of the pan and seat hinge area straightforward.
S-Trap & P-Trap Compatible — Flexible Set-Out
The Grande supports both S-trap and P-trap installations, making it suitable for a wide range of existing plumbing configurations. Standard S-trap set-out is 90mm–160mm (using the supplied vario pan connector and 20mm offset pan collar). P-trap installation height is 185mm from finished floor level using a straight connector (not supplied).
The water inlet accommodates top left rear entry or right/left pan side entry, providing further flexibility for tight or non-standard rough-in situations.
Complete Suite — Everything Included for Installation
The Grande is supplied as a complete suite ready for installation. Included components: Grande toilet pan, Grande cistern (4.5/3L), toilet seat (choice of Elite, Slim, or Wrap Over), vario pan connector, 20mm offset pan collar, fill valve for top left rear entry, fill valve for pan side entry (supplied with pan), top left rear entry water supply hose, 2× caps for pan side entry holes, 1× hose ring for pan side entry hole, and floor fixing kit.
Pan side entry water supply hose must be purchased separately if a pan side entry setup is required.
