Fienza Sona Smart Toilet Suite S-Trap 90-160 Bidet Toilet with Auto Flush & Heated Seat KS100A

How do I know if I need the KS100P, KS100A, or KS100B?

It depends on where your waste pipe is located and what set-out your plumber measures. KS100P is the P-Trap option for wall waste. KS100A suits S-Trap floor waste with a 90-160mm set-out. KS100B suits S-Trap floor waste with a 160-230mm set-out. Always confirm the set-out before ordering.

What makes the Sona Smart Toilet different from other smart toilets?

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.

Can the KS100A be installed in any bathroom?

The KS100A suits bathrooms with an S-Trap floor waste and a measured set-out between 90mm and 160mm. If your waste exits through the wall, or the floor set-out falls outside that range, you will need a different Sona model.

What electrical and plumbing requirements are needed?

Sona requires both 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 is required. All electrical work must comply with AS/NZS 3000 standards.

What hygiene and wellness features does Sona include?

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.

Is Sona safe and compliant with Australian standards?

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.

Can the Sona Smart Toilet be cleaned like a regular toilet?

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, but do not spray water directly on the seat or plug.

What happens if there’s a power outage?

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.

Does Sona require a hot water connection?

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

Who should install and service the Sona Smart Toilet?

Installation must be performed by a licensed plumber and electrician. For service or support, contact your Fienza retailer or email help@fienza.com.au with photos and details of the issue.

Is an RPZ valve required with the Sona Smart Toilet?

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.

How is Sona priced compared to other smart toilets?

Fienza 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 - they have created a product that delivers premium smart toilet performance without the usual premium price tag.

What is covered under warranty?

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