600mm Compact Back to Wall Toilet Suite
Designed for modern bathrooms and renovation projects, this Kohler Reach™ Compact Toilet Suite combines a short 600mm projection, concealed trapway design, and flexible S-Trap / P-Trap installation options. The compact footprint makes it ideal for smaller bathrooms while maintaining everyday comfort, efficient dual flush performance, and a clean streamlined appearance.
Short Projection — 600mm Compact Design
With only 600mm projection from wall to pan front, this compact toilet suite is ideal for smaller bathrooms, powder rooms, and renovation projects where floor space is limited.
The reduced depth improves movement space and helps compact bathrooms feel more open without sacrificing comfort.
S-Trap & Optional P-Trap Compatibility
Supplied with a default S-Trap set-out of 90–170mm using the vario pan connector, this suite also supports optional P-Trap installation with 180mm roughing-in.
This flexibility makes replacement easier when matching existing plumbing layouts during bathroom upgrades.
Highest Quality Vitreous China Construction
Made from premium vitreous china with a smooth gloss white finish, this toilet suite offers strong durability, long-lasting performance, and a clean modern appearance.
The non-porous glazed surface helps resist stains and makes everyday cleaning easier, supporting better hygiene and long-term maintenance.
4 Star WELS Rated Dual Flush System
Featuring a 4.5/3L dual flush system with 4 Star WELS approval, this toilet helps reduce water usage while maintaining reliable flushing performance for daily use.
The efficient flush design supports both environmental savings and lower long-term household water costs.

📐 How to Choose the Correct Trap Option
Before selecting your toilet trap option, it's important to check your set-out distance (rough-in) — the distance from the finished wall to the centre of the waste outlet.
This toilet includes a default S-Trap option and also supports an optional P-Trap installation depending on your plumbing setup.
Tip: Measure from the finished tiled wall (not the skirting board) to ensure accurate installation.
Toilet with Default S-Trap (90–170mm)

🧭 Quick Selection Guide
