Meet the toilet that thinks for you. The Fienza Sona Smart Toilet Suite (KS100) brings intelligent bathroom technology to Australian homes without compromise. Designed as a back-to-wall suite, it pairs a sleek ceramic pan and cistern with an integrated smart seat — delivering 13 automated comfort and hygiene features controlled by remote, foot sensor or side knob.

From the moment you approach, Sona responds. The foot sensor opens the seat cover automatically as you walk up, and closes it after use. A powerful hands-free jet tornado flush activates with a wave of the foot. Rear and front bidet wash functions deliver personalised hygiene with adjustable water temperature, spray pressure and nozzle positioning. When you're done, warm air drying finishes the job — no paper required.

Heated seating takes the chill out of cold mornings, with four temperature settings adjustable via the included wall-mounted remote. The self-cleaning nozzle runs a 60-second purge cycle automatically. A soft blue LED night light illuminates the bowl — practical at night, quietly beautiful any time.

Rated 4 Stars under WELS (4.4L full flush / 3.1L half flush, 3.3L average), the Sona delivers genuine water efficiency alongside advanced bidet functionality — significantly reducing paper consumption too. Energy-saving mode activates after 10 minutes of inactivity.

Available in three configurations to suit your existing rough-in: P-Trap, S-Trap 90–160mm, or S-Trap 160–230mm. Installation requires both a licensed plumber and a licensed electrician — the unit can be hardwired or connected to a standard 240V switched power point within 1 metre of the pan.

FAQ

Sona is designed for Australian homes, featuring a back-to-wall design that makes it easier to retrofit into existing bathrooms. It combines comfort and innovation, offering auto open and close, auto flush, heated seat, bidet functions, and energy-saving technology.

Yes. Sona is designed to fit most standard toiletset-outs(90–230mm) and can be installed as a retrofit by a licensed plumber and electrician. It can be hardwired or plugged into a standard 220–240V power point.

Sonarequiresboth cold water and 240V power. For hardwired installations, a switched power supply is needed for resetting. For plug-in models, a switched power point within 1m of the toilet isrequired. All electrical work mustcomply withAS/NZS 3000 standards.

Sona offers front and rear wash functions with adjustable temperature, pressure, and nozzle position. It also includes warm air drying, self-cleaning nozzles, and a soft blue night light for visibility at night.

Yes. Sona meets AS/NZS 1172.1 & 1172.2 for toilets and AS 2845.2 for backflow prevention. It also includes dual check valves and an air gap system to prevent contamination of the water supply.

Yes. Simply use mild, soapy water and a soft cloth to clean all ceramic and seat surfaces. Avoid harsh chemicals, acids, or abrasive brushes. The unit is IP44 water-resistant, butdonot spray water directly on the seat or plug.

In the event of a power outage, the toilet can still be flushed manually using the cistern half-flush button. Once power returns, all smart functions will resume automatically.

No. Sona connects to cold wateronly and heats it instantly as needed for washing and drying functions.

Installation must be performed by a licensed plumber and electrician.

The Sona smart toilet comes equipped with two forms of backflow prevention; an inbuilt air gap and installed dual check valve. In the majority of installation situations, no additional backflow prevention is required. However, an RPZ device may be required under local regulations. Please check with local authorities to confirm if a RPZ valve is required for your specific installation.

We developed Sona to meet the same core standards, safety requirements, and functionality found in higher-priced smart toilets, but at a more accessible entry price point. By focusing on the features Australians value most — wellness, comfort, hygiene, and easy retrofit installation — we’ve created a product that delivers premium smart toilet performance without the usual premium price tag.

Sona includes a 2-year warranty on the smart seat and electronic components (1 year labour), and 5-year warranty on the ceramic toilet pan (1 year labour). Warranty claims require proof of purchase and supporting photos or videos.
