Designed to replace the seat on a compatible toilet, a bidet seat adds washing functionality without needing a separate fixture. Depending on the model, warm water, a heated seat, and air drying can be useful features. They can make it a practical upgrade to your current bathroom.
But will one fit your toilet? Do you still need to wipe? Is it worth the investment? Here’s what to know before choosing a bidet seat for your home.
How does a bidet seat work?
With an electronic bidet seat, you stay seated after using the toilet. Then you select a wash setting using a side control panel or remote. A nozzle directs water towards the area being cleaned. Depending on the model, you can adjust the spray position, pressure and water temperature.
The washing water comes from your home’s water supply, not from the toilet bowl. Electric models use power for features such as water heating, heated seating and air drying.
How much does a bidet seat cost?
Whether you choose a non-powered bidet seat, a powered seat, or a fully integrated smart toilet will affect the cost.

What is the difference between a bidet seat and a smart toilet?
A bidet seat replaces the existing seat on a compatible toilet.
A smart toilet is a complete toilet with integrated functions. Depending on the model, these may include bidet washing, drying, automatic lid operation or automatic flushing.
For an existing bathroom, start by checking seat compatibility. For a renovation or new build, compare options before finalising the plumbing and electrical layout. Explore Elite’s range of smart toilets and bidet seats to see the available options.

Is a bidet seat worth considering?
A gentler way to clean: washing with water can reduce the need for repeated wiping. This may make cleaning more comfortable, especially for people who find toilet paper abrasive.
Comfort you can adjust: adjustable wash settings let you tailor the experience. Heated seating and air drying add further comfort, but features do vary between models so it’s important to check these.
The Code Interiors Purity Bidet Seat with Remote includes a heated seat and an air dryer. It offers four adjustable heat levels. The Englefield Bidet Seat Plus with Remote offers adjustable wash settings, a heated seat, and warm air drying. It also opens and closes the toilet lid automatically.
If you prefer a simpler option, the Code Purity Non-Powered Bidet Seat provides front and rear washing. It has adjustable water pressure and doesn't need electricity.
Easier access to controls: A washing function can make it easier to use the toilet. This can help someone who finds it hard to reach or twist. A remote positioned within easy reach can also be useful. Consider the person using the seat as well as the features.

Do you still need toilet paper with a bidet?
You may still want a small amount for drying or checking that you are clean. If the seat includes an air dryer, you can use that instead, or combine the two. A dryer takes time, so keeping toilet paper is practical for household members and visitors.
How do you use a bidet seat for the first time?
The controls can vary between models and brands, but the basic routine is straightforward:
1. Use the toilet as normal and remain seated.
2. Select the appropriate wash function.
3. Start with low pressure and find a comfortable water temperature.
4. Adjust the nozzle position if your model allows it.
5. Stop the wash, then gently pat dry or use the air dryer if the model has one fitted.
Read the instructions before your first use. You should not need an intense spray to feel clean, and using a bidet does not replace washing your hands.

Are bidet seats hygienic?
A bidet seat can be a hygienic way to clean when used correctly and maintained. A self-cleaning nozzle is useful, but it does not mean the whole seat cleans itself. You still need to clean the seat, the surrounding surfaces and the nozzle as directed by the manufacturer.
Will a bidet seat fit my existing toilet?
Possibly, but bidet seats are not universally compatible. Before buying, check:
- The toilet's bowl shape, length and width
- The spacing between the seat mounting holes
- Clearance between the mounting holes and cistern
- Access to the water connection
- Whether a suitable power connection is needed
It is important to check the manufacturer’s fitting template where available. A toilet that looks similar in photos may still have different dimensions.
The Code Interiors Purity Non-Powered Bidet Seat and the Purity Bidet Seat with Remote are compatible with the Code Interiors Flow Standard Height BTW, Pure Overheight BTW, Flow Inwall Toilet and Pure Inwall Toilet.
The Englefield Bidet Seat Plus and the Englefield D Shape Bidet Seat can retrofit to a range of toilets, with compatibility checked against their fitting template. It's recommended to confirm your exact toilet model before ordering any bidet seat.
Do bidet seats need electricity?
Not all of them. The right option depends on the functions you want.
The Code Purity Non-Powered Bidet Seat needs no electrical connection. It uses cold, unheated, ambient-temperature water and has a quick-access knob, self-cleaning nozzle and a soft-close seat.
Electronic models, including the Code Purity Bidet Seat with Remote and the Englefield Bidet Seat Plus and the Englefield D-Shape Bidet Seat need a power connection.
If you are renovating, choose the model early so your electrician can plan a suitable power connection.
Can I install a bidet seat myself in New Zealand?
No. You'll need a plumber to check the water connection and backflow protection, plus an electrician if a powered seat needs a new electrical connection.
Backflow prevention helps prevent contaminated water flowing back into the clean water supply. This matters for non-powered bidet seats as well as powered seats.
Can I still use water to wash without adding a bidet seat or a smart toilet?
Yes. A handheld bidet spray is an alternative if you would like water cleansing while keeping your existing toilet seat. A handheld bidet spray has a hand piece and hose beside the toilet, so you can direct the water where needed while seated.
Check whether your chosen spray includes a mixer. Some models include one, while others supply the hand-piece and hose only. If the spray doesn't include a mixer, you'll need to buy a compatible shower mixer to install beside it. This controls the water supply and lets you turn the flow on and off.
A handheld spray also needs appropriate backflow prevention. When this is not built into the product, a separate RPZ valve must be installed by a plumber. Allow around $500 or more for the valve, plus plumbing installation costs.
Before purchasing, check the complete setup, the hand piece, any separate mixer, backflow prevention and installation. This will help you understand the total cost and plan accordingly.

How much does a bidet seat cost to install and run?
The purchase price is only part of the cost. Before choosing a bidet seat, check what backflow prevention it includes and what your plumber will need to install it.
Both the Code Purity Bidet Seat with Remote and Non-Powered Bidet Seat need a separate RPZ valve, which is not included. Allow for around $500 or more for the valve alone, plus the cost of installation by a plumber. Your plumber will need to confirm its location and access requirements. If it is positioned behind the wall, provision must be made for access, testing and servicing, so it is worth planning this before walls are finished.
Some bidet seats and smart toilets have suitable backflow prevention built into the unit, which may remove the need for a separate external RPZ valve. Check the exact model’s specifications and have your plumber confirm the requirements before purchasing. Comparing the complete installed cost will give you a more realistic idea.
When it comes to the cost of running a bidet, a non-powered bidet seat has no energy consumption, although it still uses water. For electronic seats, running costs will depend on the mode, settings, frequency of use and your electricity rates.
Also, allow for any replacement filters, servicing and backflow-device testing required for your installation. For example, Englefield specifies a 6-month water-filter replacement interval for its Bidet Seat Plus.
What is the downside of a bidet seat?
The main considerations are the upfront cost, fitting requirements and ongoing cleaning. Electronic seats also need power, and air drying may take a little longer than using toilet paper. With a non-powered bidet, you need to be comfortable with an unheated wash.
The seat shape and control layout can feel different from your current toilet. Before buying, check the seating space, make sure the controls are easy to reach, and find out what maintenance is needed.

Is a bidet seat worth it?
A bidet seat is worth considering if you value water-based cleaning, adjustable comfort and like to use less toilet paper. A compatible replacement seat can bring those benefits into an existing bathroom without replacing the whole toilet.
The best choice is the one that fits your toilet, suits the people using it and comes with an installation cost you understand. Have your toilet model or measurements ready so compatibility and installation requirements can be checked before you place your order.
So, should I choose a bidet seat or a smart toilet?
Choose a bidet seat if your existing toilet is compatible and you want to keep it. It's a lower cost starting point. However, if you wish to add a powered bidet seat to your existing toilet, you will need to make sure you have an electrical outlet in order for the powered bidet to work.
Choose a smart toilet if you're replacing your toilet or renovating. The toilet and bidet functions are designed as one unit, with additional automatic features available on selected models.
Choose a handheld spray if you want to keep your existing toilet and seat and prefer to direct the water yourself. If you choose this option, don't forget the RPZ valve that will need to be installed.
Compare the total installed cost, including plumbing, electrical work and any required RPZ valve. Some models have built-in backflow prevention, while others need it installed separately.
