Toilet Types We Install
From traditional to cutting-edge smart technology

Traditional design with cistern mounted directly to pan. Easy installation, wide choice of styles, and straightforward maintenance. Ideal for standard bathroom layouts.
Wall-Hung Toilets
Modern floating design with concealed in-wall cistern. Saves floor space, easier cleaning underneath, and sleek minimalist aesthetic. Requires Geberit or similar frames.
Back-to-Wall Toilets
Pan sits against wall or furniture with concealed pipework. Clean lines, no visible cistern or plumbing, and flexible height adjustments for comfort.
Comfort-Height Toilets
Standard or wall-hung toilets with pan height 460-480mm (vs standard 400mm). Easier sitting and standing for seniors, tall individuals, or mobility challenges.
In-Wall Cistern Systems
Cistern concealed within wall cavity behind custom flush plate. Maximises space, quieter operation, and customisable flush buttons to match bathroom design.
Smart Toilets
Integrated bidet function, heated seat, auto-open lid, remote control, and warm air dryer. Premium hygiene, comfort, and technology for luxury bathrooms.
8-Stage Toilet Installation Process
Professional workflow ensuring perfect results every time
Site Assessment & Toilet Selection
Measure existing rough-in distance (distance from wall to waste outlet), assess floor type, check for level surfaces, and confirm toilet compatibility. Discuss WELS rating, style preferences, and budget.
Remove Existing Toilet
Isolate water supply, drain cistern and pan, disconnect water line, remove pan bolts, break seal, and carefully lift off toilet. Inspect flange, waste pipe, and floor condition for damage or repairs needed.
Prepare Mounting Surface
Clean and inspect toilet flange, replace worn wax ring or rubber seal, check floor is level (shim if required), repair any tile damage, and ensure waste outlet is clear and properly aligned.
Install In-Wall Frame (Wall-Hung)
For wall-hung toilets: install Geberit Duofix or equivalent frame, secure to structural studs, set mounting height (standard or comfort), connect waste and water supply, and pressure test before wall closure.
Position & Secure Toilet Pan
Position new pan over flange ensuring correct alignment, install new wax ring or rubber gasket, secure pan with stainless steel bolts, check level in all directions, and seal base with premium silicone.
Install Cistern & Connect Water
Mount cistern to pan (close-coupled) or install flush plate (in-wall), connect flexible water supply with isolation valve, install fill valve and flush mechanism, and adjust water level for optimal flush.
Test Flush & Check for Leaks
Fill cistern, test dual-flush operation, check for leaks at pan base and water connection, verify proper bowl refill, test soft-close seat mechanism, and confirm strong, complete flush action.
Final Sealing & Cleanup
Apply final silicone seal around base, clean excess sealant, polish all chrome and ceramic, remove old toilet and packaging, vacuum work area, and demonstrate flush settings and care instructions.
Advanced Toilet Features
Water efficiency, hygiene, and comfort innovations
Dual-Flush Systems
WELS 4-star rated dual-flush mechanisms deliver 3L half-flush and 4.5L full-flush. Saves up to 35,000 litres annually compared to single-flush toilets. Adjustable flush buttons for precise control.
Soft-Close Seats
Hydraulic dampers prevent seat slamming, reducing noise and preventing hinge damage. Quick-release clips allow easy removal for deep cleaning. Durable stainless steel hinges resist corrosion.
Rimless Bowl Technology
Rimless design eliminates hidden bacteria traps under traditional rim. Direct-flush technology provides powerful, hygienic clean with every flush. Easier to clean and more sanitary than rimmed bowls.
Geberit In-Wall Frames
German-engineered concealed cistern frames rated to 400kg load capacity. Adjustable height, pre-insulated to reduce flush noise, and accessible service panel allows maintenance without wall removal.
Sensor Flush Technology
Touchless operation ideal for commercial or high-hygiene residential bathrooms. Battery or mains powered options, adjustable sensor range, and dual-flush programming for water efficiency.

AS/NZS 3500 Plumbing Code
Waste pipe sizing, fall requirements, vent stack connection, and backflow prevention must comply. All work certified with NSW Certificate of Compliance.
Backflow Prevention
Toilets with integrated bidets, handspray attachment points, or flexible fill hoses require testable backflow prevention devices (RPZ or dual check) to protect water supply.
Accessibility Standards (AS 1428)
Ambulant and accessible toilets require specific height, clearance, and grab rail mounting. We ensure compliance for aged care, disability access, and universal design bathrooms.
