If you are shopping for a bidet, you will quickly hit a fork in the road: do you buy a complete all-in-one bidet toilet suite, or add a bidet seat to the toilet you already own? Both give you a warm-water wash and a more hygienic bathroom — but they suit different homes, budgets and renovation plans. This guide explains how all-in-one bidet toilets work, where they shine, and how The Bidet Shop's Australian range fits each option.
What Is an All-in-One Bidet Toilet?
An all-in-one bidet toilet — often called a bidet toilet suite, integrated bidet toilet, or smart toilet — combines the toilet pan and the bidet into a single, purpose-built unit. Instead of bolting a washing device onto a standard toilet, everything is engineered together: the bowl, the washing nozzles, the seat, the dryer and the controls all live in one seamless fixture.
Bidet Toilet Suite vs Bidet Seat — What's the Difference?
Replaces your whole toilet
- Pan and bidet engineered as one unit
- Sleek, seamless look — no joins or add-ons
- Full suite of smart features built in
- Best for renovations and new builds
- Higher upfront investment
- Requires full toilet replacement
Upgrades your existing toilet
- Keeps your current pan — just swap the seat
- Same warm-water wash, heated seat & dryer
- Faster, lower-cost upgrade
- Wide price range — entry to luxury
- Ideal for rentals and existing bathrooms
- Licensed plumber still required for water connection
Why Choose an All-in-One Bidet Toilet Suite?
A Seamless, Modern Look
Designed as one piece with no joins, gaps or a separate seat unit sitting on top. The result is a sleek, contemporary fixture that looks at home in a renovated or new-build bathroom — ideal if appearance matters as much as function.
Every Smart Feature in One Unit
Suites are where you find the full suite of smart toilet features: automatic open/close lids, sensor or foot-activated flushing, night lights, deodorisers, adjustable warm-water washing, warm-air drying and a heated seat — all built in and controlled together.
Easier to Keep Clean
With fewer crevices than a seat-on-pan setup, and features like self-cleaning nozzles and rimless or easy-clean bowls, an integrated unit is generally simpler to wipe down and keep hygienic.

View Product →Prefer to Keep Your Existing Toilet? Consider a Bidet Seat
A full suite is not the only path. If your toilet is in good condition, a bidet seat delivers the same warm-water wash for a fraction of the price and avoids replacing the pan. The Bidet Shop groups its seats into clear tiers.
Entry Range
From ~$890A great first step into bidet comfort. Covers the essentials and fits most standard Australian toilets.
Mid Range
From ~$1,290The sweet spot for most Australian households — remote control, heated seat, warm-air dryer, and premium wash at a sensible price.
Luxury Range
From ~$1,490Premium features without replacing the toilet — for buyers who want the best wash, drying and comfort experience on their existing pan.

Installation & Australian Compliance
Whichever you choose, installation in Australia is governed by real plumbing rules — and getting them right protects both your home and your drinking water.
WaterMark Certification
Every bidet product connected to the water supply must carry a valid WaterMark certification. The current mandatory product specification for bidet seats and toilet suites is WMTS-051:2021, published by the Australian Building Codes Board. The Bidet Shop's range is certified under this standard to Lic. No. 20094. You can verify any product on the WaterMark Product Database. It is illegal to sell or install a non-certified bidet in Australia, and doing so may void your home insurance.
Backflow Prevention & Licensed Installation
Because a bidet connects to your potable (drinking) water supply, it must be installed with appropriate backflow protection under the National Construction Code Volume Three (Plumbing Code of Australia), AS/NZS 3500.1, and AS/NZS 2845.1.
Where the spray outlet can sit within 25mm of the pan's overflow level in any position, the installation is classified as high hazard and requires a Reduced Pressure Zone Device (RPZD) or registered air gap. High- and medium-hazard devices must be tested at installation and then annually by a licensed plumber. Many WaterMark-certified bidet seats include an integral air gap or atmospheric vacuum breaker (AVB) that may satisfy the backflow requirement — your plumber will confirm this by checking the WaterMark database. Smart toilet suites typically require both a plumbed-in connection and a nearby 240V power point; factor in an electrician's visit if yours is not already in place.

Frequently Asked Questions
What's the difference between a bidet toilet and a bidet seat?
A bidet toilet (suite) is a complete integrated unit that replaces your whole toilet — pan and bidet are engineered as one. A bidet seat replaces only the seat on your existing toilet pan. Both wash with warm water; the suite is the premium, seamless option, while the seat is the more affordable, faster upgrade that avoids replacing the toilet itself.
Do all-in-one bidet toilets need special plumbing?
They connect to your standard toilet water supply — no special pipes are required. However, like all bidet installations in Australia, they must be fitted with proper backflow protection to meet the National Construction Code (NCC Volume Three) and AS/NZS 3500.1. Smart toilet suites also require a 240V power point nearby. A licensed plumber handles the water connection and certification; an electrician handles the power point if one needs to be added.
Can I install a bidet toilet suite myself?
No. In Australia, connecting any bidet or bidet toilet suite to the water supply is regulated plumbing work that must be done by a licensed plumber. The plumber is responsible for backflow prevention and will issue a compliance certificate. DIY plumbed-in installation is illegal in every state and territory, and may void your home insurance. Portable, non-plumbed bottle bidets are the only exception — but all fixed installations require a professional.
The good news: the water connection for a bidet seat or suite is typically straightforward, and most licensed plumbers complete it efficiently. The Bidet Shop can help refer you to a local installer — call 1300 243 387.
Are bidet toilet suites NDIS or DVA eligible?
Some bidet seats in The Bidet Shop's range — such as the Coway BA-08 — are listed as NDIS and DVA eligible. For smart toilet suites, eligibility depends on the individual's circumstances and their OT or support plan. The Bidet Shop has a dedicated medical and disability support team who can advise. Contact them on 1300 243 387 or visit the Medical & Disability page.
The Bottom Line
An all-in-one bidet toilet suite is the ultimate bathroom upgrade — seamless, feature-packed and purpose-built as a single unit — while a bidet seat brings the same daily comfort to the toilet you already own at a much lower cost. The Bidet Shop carries both, from the $98 cold-water entry point all the way to the Throne Smart Bidet Toilet Suite and the flagship KING Throne, all WaterMark certified to WMTS-051:2021 and backed by an in-house Australian support and install team.
