St George Smart Toilets (Intelligent Toilets)

The four St George toilets on this page

This page lists four St George smart toilets, the Byron, Brighton, Coogee and Mosman, all in gloss white. Each is an integrated unit with a built-in tank, a bidet wash, a heated seat and a remote control, and each is rated 4 star under WELS at 4.5 and 3 litres per flush, a 3.5 litre average. The models differ in their hygiene and automation features. For smart toilets from other makers, see smart toilets and bidets, and for the Caroma range see Caroma smart toilets and bidet seats.

What separates the models

The Byron is the entry model. It has rear and front wash with adjustable pressure, a heated seat with adjustable temperature, automatic flushing, a self-cleaning wand nozzle and a soft night light. Its Verticoat ceramic glaze reduces residue build-up, and the Jetflush built-in tank delivers consistent performance. It suits a main or secondary bathroom where smart functionality is the goal but a straightforward setup is wanted.

The Brighton adds a warm air dryer with adjustable temperature, wide front and pulsating wash modes, an automatic deodoriser and a removable bidet unit. It is the first model in the range to make paper-free use practical every day, and it suits a main family bathroom where daily comfort and hygiene both matter. Auto flush and remote lid operation reduce contact with surfaces.

The Coogee brings UV sterilisation of the spray wand, an auto open and close lid and an Air-mix Wonder Wash, along with a dryer and a deodoriser. It suits a master ensuite or any bathroom where hands-free use matters. The Mosman is the top model. It sterilises both the washing water and the wand with UV, and it has a kick flush that works without a remote or panel. It also has the removable bidet unit and the fullest list of wash modes, including rear, front, wide front, pulsating and female soft wash.

Sizes, trap and inlet

All four use a universal S or P trap, with an S trap set out of 140 to 260mm and a P trap set out of 180mm, and all four take a bottom inlet. The Byron is 507.2mm high with a 430mm pan height, a 684mm projection and a 398mm width. The Coogee is 505mm high with a 468mm pan height, a 694mm projection and a 414mm width. The Brighton is 480mm high with a 435mm pan height, a 683mm projection and a 403.3mm width. The Mosman is 482.5mm high with a 435mm pan height, a 683mm projection and a 384.8mm width. Measure your space against the projection and width before you order. The toilets page explains set out and inlet.

Seat height

The seat height from the floor to the top of the seat is 430mm for the Byron, Brighton and Mosman and 470mm for the Coogee. AS 1428.1 gives a top of seat to floor height of 460mm to 480mm for an accessible toilet. The Coogee falls inside that range and the other three sit below it. No St George suite is an accessible fit-out, so treat the height as information. If accessibility is the aim, have an access consultant or certifier confirm the room.

Each model in detail

The Byron suits a household that wants the essentials without extra complexity. Rear and front wash with adjustable pressure is cleaner and more comfortable than paper alone. The seat is heated with adjustable temperature, so it is warm from the moment you sit down. Flushing is automatic and hands free, which leaves one less surface to touch. The Jetflush built-in tank keeps the flush reliable and consistent even at lower water pressure, the self-cleaning wand nozzle maintains hygiene before and after each use, and the soft night light means no need to switch on the overhead lights for a middle-of-the-night visit.

The Brighton is the step to take if warm air drying is on your list. The dryer has adjustable temperature, and with wide front and pulsating modes and a female soft wash for gentle, targeted cleansing, it offers more wash options than the Byron. The automatic deodoriser keeps the bathroom fresh without manual effort, and the removable bidet unit makes cleaning and routine maintenance more straightforward. The Verticoat glaze means less scrubbing.

The Coogee suits a master ensuite or any bathroom where hygiene standards matter most. The UV-sterilised wand sanitises the nozzle automatically, so it is clean every time and not just when you rinse it. The lid opens and closes by itself, the Air-mix Wonder Wash infuses the water with air for a gentler cleanse, and the wash modes are rear, front, pulsating and female soft wash with adjustable temperature and pressure. The heated seat and the warm air dryer are independently adjustable for personal preference, and the energy saving mode manages power consumption automatically during lower-use periods.

The Mosman is the one with dual UV hygiene protection, sterilising both the washing water and the wand. Kick flush activation means flushing without a remote, a panel or a sensor. The wash suite covers rear, front, wide front, pulsating and female soft wash with precise control, and the comfort features are a heated seat, a warm air dryer with adjustable settings, an auto open and close lid with automatic flush, an integrated deodoriser and the removable bidet unit. The Verticoat glaze and Waterfilm pre-rinse complete the hygiene system.

Materials, certification and fit-out

All four are vitreous china in a gloss white glaze with an easy clean coating. All St George intelligent toilets and their relevant components are Watermark certified, and each is rated 4 star under WELS at 4.5 and 3 litres. The backflow protection is an atmospheric vacuum breaker, and the water inlet is at the bottom. Plan the supply on the bottom inlet side, and leave room for the T-valve in the box. The remote comes with the unit, and the Brighton and Mosman also include the removable bidet unit in the box.

When you compare the four, start with the room. Check the projection against the door and the vanity, since the units run from 683mm to 694mm. Check the width, which runs from 384.8mm on the Mosman to 414mm on the Coogee. Check the height under any shelf, which runs from 480mm to 507.2mm. Then choose the features, because every model shares the same plumbing and the same 1200 watt supply.

Water: pressure, volume and what the unit will not accept

The minimum supply is 5 litres per 15 seconds at a stable pressure of at least 200 kilopascals, and the maximum pressure capacity is 500 kilopascals. The comparison figure for working water pressure is 250 to 500 kilopascals. Ask us which lower figure applies before you order. Use potable water only, and never seawater or recycled water.

The built-in tank gives stable flushing at low pressure, but that does not remove the minimum. Have the plumber measure the supply pressure and flow before you choose.

Backflow protection

Each model complies with WMTS-051 and has an integrated atmospheric vacuum breaker that satisfies the high hazard backflow prevention criteria of AS/NZS 3500.1 without a reduced pressure valve. Installation must be in accordance with the AS/NZS 3500 series. Testable atmospheric vacuum breakers are suitable for high hazard protection against back siphonage, and a plumber should confirm a product's integral protection on the WaterMark database. Ask the plumber to check the St George model on the database and say whether a separate dual check valve is needed on the inlet.

Power and the room

With a 1200 watt rating and a mains supply, the toilet needs an outlet that an electrician has placed correctly. AS/NZS 3000 divides a wet area into zones. In Zone 2, a band around a fixture, for example 150mm on the wall and floor around a basin and rising 400mm above the water, only a shaver outlet or an RCD-protected outlet in a cupboard is allowed. In Zone 3, which extends a further 2.4 metres, a socket at 0.3 metres or more needs RCD protection, a separated supply or a SELV or PELV supply. The electrician decides where the outlet can go.

Every smart toilet needs a general purpose outlet within reach of the unit, typically 300mm to 500mm from the toilet, and the power point has to go in before tiling, so an electrician should be in the scope early.

A smart toilet compared with a bidet seat

A smart toilet is an integrated unit with the wash function built into the pan, and a bidet seat is a separate retrofit that sits on an existing standard suite. Smart toilets share auto flush, where sensors detect that use has finished, a heated seat, a warm air dryer and a deodoriser with built-in filters. The St George models include these in different combinations.

Because the unit is the pan, the choice is made when you choose a toilet, and the existing pan is replaced. If you would rather keep your pan, the bidet seats on bidet toilet seats are the alternative.

Looking after a powered toilet

Wipe the exterior regularly with a mild cleaner and avoid harsh chemicals, which can damage sensors or electronic parts. Check the remote and the power cord connections now and then. The units include a night light, an automatic deodoriser and, on some models, UV sterilisation. Those belong to the unit's hygiene design, and they do not remove the need to wipe the pan and the seat or to keep spray cleaners off the controls. If a sensor or panel misbehaves after cleaning, turn the power off and ask us before you use the unit again.

What comes in the box

Each box holds the toilet unit, a remote control, a T-valve and the installation instructions, and the Brighton and Mosman also hold a removable bidet unit. Ask us for the installation manual and the electrical requirements of the model you choose. Have the power point and the water connection planned with your electrician and plumber before the room is finished. If you would rather keep your toilet and add washing, see bidet toilet seats.
