Bidet prices in Australia span a wide range — from under $100 for a portable to several thousand for a smart toilet suite. The right budget depends on the type you choose and what installation your bathroom needs. This guide breaks down realistic prices using The Bidet Shop's current range, plus the installation and running costs people often forget.
The Short Answer
As a guide, expect roughly: portable bidets from around $98–$99; cold-water attachments and handsprays from around $98–$250; entry electric seats from around $890; mid-range seats around $1,290–$1,690; luxury seats up to around $1,992; and complete smart toilet suites from around $3,490 to $5,290. On top of the unit, budget for licensed-plumber installation.

Portable & Travel Bidets
The cheapest entry point. The Bidet Shop's portable travel bidets sit around $99, with no installation cost because they don't connect to plumbing — ideal for renters and travellers.
Cold-Water Attachments & Handsprays
Non-electric options start at around $98 for a handspray Standard Kit, about $208 for a Complete Kit, and around $250 for a Slimline cold-water bidet attachment. These need plumbed installation.
Entry Electric Bidet Seats
Powered washing and a heated seat begin around $890 for the National N-800, with the N-1000 around $990.
Mid-Range Electric Seats
The popular tier, roughly $1,290–$1,690 — including the Eco EB-R500 (around $1,290), the National N-2000 (around $1,490) and the remote-controlled Coway BA-08 (around $1,690). This is the sweet spot for most Australian homes.
Luxury Seats
Premium seats run up to around $1,992 (for example the InteliClean Air 9000), adding the full feature set without replacing the toilet.
Smart Toilet Suites
All-in-one smart toilet suites start around $3,490 (Throne Smart Bidet Toilet Suite) and rise to around $5,290 for the flagship KING Throne.
The Other Cost: Installation
A bidet's sticker price isn't the whole story — plumbed models must be professionally installed.
DIY Installation Is Illegal in Australia
Connecting any bidet to the water supply is licensed plumbing work. DIY plumbed-in installation is illegal under Australian law, can contaminate your drinking water, and may void your home insurance. Only portable bottle bidets — which don't connect to plumbing — are exempt.
Licensed Plumber & Backflow Prevention
In Australia, a licensed plumber must connect the bidet and fit appropriate backflow protection to meet the National Construction Code Volume Three and standards AS/NZS 3500.1 and AS/NZS 2845.1. A straightforward seat install is modest; the exact cost depends on your bathroom and what backflow device is required.
When You Need a High-Hazard Device (RPZ)
If the spray outlet can sit within 25mm of the pan overflow (common with handsprays and many seats), a high-hazard device such as a reduced pressure zone (RPZ) valve is required. The device plus fitting adds noticeably to the total cost. The Bidet Shop's Pressure Reducing Valve 350KPA (around $48) helps manage mains pressure where needed.
Annual Backflow Testing
High- and medium-hazard backflow devices must be tested by a licensed plumber every year — a small recurring cost worth factoring in.
Adding a Power Point (Electric Models)
Electric seats and smart toilets need a power point nearby. If your bathroom doesn't have one, a licensed electrician's fee to add a safe, RCD-protected outlet applies. Budget for this from the start.
Running Costs: Are Bidets Expensive to Own?
Day to day, bidets are cheap to run. Electric models use small amounts of power for seat and water heating, and water use per wash is tiny — far less than the water needed to manufacture the toilet paper they replace. Many households offset much of the purchase through reduced toilet-paper spending over time.
How to Get the Best Value
Match the bidet to your real needs rather than over-buying: a mid-range seat suits most homes, while a suite makes sense in a renovation. Watch for sales (The Bidet Shop frequently discounts models), check warranty length, and factor installation into your budget from the start. A WaterMark-certified product from a specialist with its own repair team protects your investment long term.

Frequently Asked Questions
For a quality electric seat with warm water, a heated seat and a remote, expect roughly $1,290–$1,690 — the mid-range sweet spot for most Australian homes. If budget is tighter, a cold-water handspray kit from around $98 is a capable, affordable entry.
It varies with your bathroom and the backflow protection required. A simple seat install is modest; jobs needing a high-hazard RPZ device or a new power point cost more. Ask The Bidet Shop for a quote — their certified team handles the full job including backflow and electrical work.
Often, yes. Reduced toilet-paper use can offset a meaningful portion of the purchase over the years, on top of the comfort and hygiene benefits. The savings are more significant at higher toilet-paper consumption — so bigger households tend to recoup costs faster.
The Bottom Line
A bidet can cost as little as around $99 for a portable or several thousand for a smart toilet suite — with most quality electric seats in the $1,290–$1,690 range, plus licensed-plumber installation. Budget for the unit, the install (including any backflow device and power point), and you'll know the true cost up front. Compare prices across the range or call 1300 243 387 for a tailored quote.
