The best smart toilets in Australia with both bidet washing and automatic flushing include the TOTO Neorest RS, the Kohler Veil Intelligent, the TOTO RW and SW wall-hung washlet suites, and the Lafeme Crawford and Sesto autoflush packages. These integrated units combine warm-water bidet cleansing, hands-free auto flushing, heated seats and self-cleaning nozzles in a single suite. Prices range from around $3,600 to $19,000 depending on the model, finish and installation requirements. You can see the full smart toilet range at Austpek Bathrooms.
This guide covers units that do both: a bidet washlet and automatic flushing. Many smart toilets offer one or the other, so every model below delivers both features in one integrated suite.
What are Bidet and Auto Flush in Smart Toilets
Two features define this category, and they are often confused with each other:
-
Bidet washing uses a retractable nozzle to deliver warm-water cleansing, usually with adjustable spray position, water pressure and temperature, often followed by a warm-air dryer. This is the washlet function popularised by Japanese bathroom technology.
-
Auto flush uses a sensor to detect when you have finished and flushes automatically, with no button or lever. It is different from an auto lid, which opens and closes the seat lid automatically but does not flush on its own.
A bidet-and-auto-flush smart toilet does both in one integrated suite. When comparing models, confirm the unit lists auto flush, since some suites advertise auto lid or remote flush without sensor-based automatic flushing.
Best Smart Toilets with Bidet and Auto Flush in Australia
1. TOTO Neorest RS - Best Overall Integrated Smart Toilet
The TOTO Neorest RS is the benchmark integrated smart toilet for Australian bathrooms. It combines an integrated bidet washlet with automatic flushing, an automated lid, warm-water cleansing, a heated seat and TOTO's bowl pre-misting and glaze technology that helps keep the bowl clean between uses. As a one-piece integrated suite there is no separate washlet seat to retrofit, which gives it the cleanest finish in the range.
It sits at the premium end. For homeowners who want the most refined bidet and auto-flush experience available, it is the standout choice.

It is the strongest mid-range pick and the only unit here with UV nozzle sanitisation. It is also available in a wall-hung version.
One installation note: the required high-hazard backflow prevention device is not supplied with this package, so budget for your plumber to fit one if your site does not already have it.

Other Smart Toilet Features Worth Considering
Bidet washing and auto flush are the headline features, but the units above carry several other functions that matter day to day. Here is how the named models compare on each, so you can match the feature set to what you care about most.
Heated Seat
- A heated seat is standard across every unit in this guide, including the full TOTO Neorest range, the Kohler Veil, and the Lafeme Crawford and Sesto. On the premium TOTO models and the Kohler Veil the seat temperature is adjustable, so you can set it warmer for cold mornings and ease it back in summer. Every unit here delivers a warm seat; the difference is the degree of fine adjustment.
Warm-Air Dryer
- A warm-air dryer dries you after washing so you can reduce or skip toilet paper. It is included on the TOTO Neorest range, the TOTO RW, the Kohler Veil, and the Lafeme Crawford and Sesto, and on the higher-tier models the airflow temperature is adjustable. It pairs with the bidet function and is part of what makes a fully hands-free routine possible.
Self-Cleaning Nozzles and Bowl Sanitisation
- Hygiene technology is where the premium units pull ahead. All the units include self-cleaning nozzles that rinse before and after each use. TOTO's Neorest range uses EWater+, which applies electrolysed water to mist and help sanitise the bowl and nozzle, plus Premist that helps prevent waste from sticking. The Kohler Veil takes a different approach with a UV-sanitising nozzle. If reducing cleaning effort is a priority, the Neorest models and the Kohler Veil are the strongest here.
Deodoriser
- A built-in deodoriser draws air through a filter to neutralise odours at the source. It features on the TOTO Neorest range, the Kohler Veil, and the Lafeme Crawford and Sesto. For ensuites and bathrooms close to living areas, this is one of the more appreciated everyday functions.
Night Light and Remote Control
- Most units include a soft night light that makes night-time use easier without harsh lighting, and a remote control (or side control on some configurations) for adjusting wash position, pressure, temperature and seat settings. The TOTO Neorest range uses soft ambient lighting, while the Kohler Veil and the Lafeme Crawford and Sesto include an LED night light. The Kohler Veil is controlled through a Bluetooth smartpad remote.
Rimless and Tankless Design
- The bowl design affects cleaning and fit. Every unit here uses a rimless bowl, which removes the hard-to-clean rim channel where grime collects. The integrated one-piece models, such as the Neorest range, also avoid a separate cistern for a tankless, space-saving profile that suits compact or minimalist bathrooms.
Adjustable Water Temperature and Pressure
- Adjustable water temperature and spray pressure let each person set the wash to their preference, and a movable nozzle position fine-tunes the spray. This is available across the integrated units here, with the widest adjustment range on the premium TOTO models. For households with varied preferences, the breadth of adjustment is worth weighing up.
What to Check Before You Buy (WELS, Backflow, Water Supply)
Three practical checks matter before committing to an integrated smart toilet in Australia:
-
WELS rating. Confirm the unit carries a Water Efficiency Labelling and Standards (WELS) rating. Most integrated smart toilets meet Australian water-efficiency requirements, and many use dual-flush systems that compare well against standard suites.
-
Backflow prevention. Because bidet smart toilets connect the water supply to a fixture used for cleansing, Australian plumbing codes require appropriate backflow prevention. Some units, including the TOTO and Lafeme suites here, ship with an integral high-hazard backflow prevention device. Others, such as the Kohler Veil, do not include one, so your plumber will need to fit the correct device. Confirm this for your chosen model.
-
Water supply. Many smart toilets are designed to connect to mains water, not rainwater or greywater, to comply with local plumbing codes and protect the internal components. Confirm your supply with your plumber before installation.
-
Power access. Integrated bidet and auto-flush functions need a power point, so factor in electrical access. A renovation is the ideal time to add this, since framing and wiring are already open.
Bidet + Auto Flush vs Bidet-Only Smart Toilets
If your priority is hands-free convenience, a bidet-and-auto-flush integrated suite is worth the step up: the sensor flush means a touch-free routine from start to finish. If budget is the main consideration, pairing a quality toilet pan with an electronic bidet seat gives you warm-water washing and a heated seat at a lower entry point, though flushing stays manual unless the suite includes auto flush. Both paths give you the core bidet experience; the difference is whether flushing is automatic or manual.

Frequently Asked Questions
What is the best smart toilet with bidet and auto flush in Australia?
- The TOTO Neorest RS is widely regarded as the best overall integrated smart toilet, combining a bidet washlet, automatic flush, auto lid and advanced bowl-cleaning technology in one suite. For a mid-range option, the Kohler Veil Intelligent delivers the same core bidet and auto-flush combination with a design-led finish at a more accessible price.
What is the difference between auto flush and auto lid?
- Auto flush uses a sensor to flush automatically once you have finished, with no button or lever. The auto lid opens and closes the seat lid automatically but does not flush on its own. A fully hands-free smart toilet includes both.
Do bidet smart toilets need a power point?
- Yes. The bidet washing, heated seat and auto-flush functions are electronic, so an integrated smart toilet needs a power point installed by a licensed electrician. This is easiest to arrange during a renovation.
Are smart toilets with bidet and auto flush water efficient?
- Most integrated smart toilets sold in Australia carry a WELS rating and use dual-flush systems, so they compare well with standard toilets on water use despite the added bidet function.
How much does a smart toilet with bidet and auto flush cost in Australia?
- Integrated bidet and auto-flush suites range from around $3,600 for value options such as the Lafeme Crawford and Sesto, up to around $19,000 for flagship models like the TOTO Neorest NX, before installation.
Can a bidet and auto flush smart toilet connect to rainwater?
- Many are designed for mains water only, to comply with Australian plumbing codes and protect internal components. Confirm your water supply and backflow prevention requirements with a licensed plumber before installation.
Do smart toilets have a deodoriser?
- Many integrated smart toilets include a built-in deodoriser that draws air through a filter to neutralise odours at the source. It features on the TOTO Neorest range and select other integrated units, and is useful in ensuites or bathrooms near living areas.
What is the difference between a heated seat and adjustable water temperature?
- A heated seat warms the seat surface for comfort, while adjustable water temperature controls how warm the bidet wash water is. The integrated units in this guide include a heated seat as standard, with the premium TOTO models offering the widest adjustment for both seat and water temperature.
Do smart toilets work in a power outage?
- The bidet, heated seat, dryer and auto-flush functions need power and will pause during an outage, but most integrated units include a manual flush option so the toilet remains usable. Check your specific model's manual for the manual flush location.
