How to Choose a Bidet Seat for Australian Toilets: Complete Buying Guide

Buying a bidet seat in Australia requires a few specific checks that most buying guides skip. Australian toilets have their own shapes, water inlet configurations, and plumbing standards — get these right and your seat installs cleanly and works perfectly. Get them wrong and you're looking at returns, adapters, or a seat that physically doesn't fit.

This guide walks you through every check you need to make before purchasing.

Step 1: Identify Your Toilet Shape

This is the most important step. Australian toilets come in two shapes:

D-shape (elongated) — The front edge of the bowl is flatter, giving the seat a D profile from above. This is the most common shape in modern Australian bathrooms.

O-shape (round) — The bowl is more circular. More common in older bathrooms and compact toilets.

To check: look down at your toilet from above. If the front is noticeably flat or angular, it's D-shape. If it curves all the way around, it's O-shape.

Why it matters: A D-shape seat on an O-shape toilet (or vice versa) will overhang, leave gaps, or won't mount correctly. The Conor Elara is one of the few bidet seats in Australia available in both D-shape and O-shape as distinct variants — which is exactly why it's our recommended non-electric seat.

Step 2: Locate Your Water Inlet

Your toilet's water inlet is almost always on the left side in Australian bathrooms. Some older or European-style toilets have a bottom inlet.

Left inlet (standard): All Conor bidet seats are compatible.

Bottom inlet (less common): Check whether an adapter is available, or consult a plumber.

To find your inlet: look behind or beside the toilet near the floor where the water supply hose connects to the cistern.

Step 3: Electric or Non-Electric?

This is the biggest decision in terms of budget and features.

Non-electric (Conor Elara):

• Cold water only
• No power outlet needed
• Simple installation — water connection only
• Lower cost
• Zero electricity running cost
• Easy to remove — good for rentals
• Sufficient for most buyers who don't specifically need warm water

Electric (Conor Lyra, Sylora, Ayora, Arista):

• Requires a power outlet within reach of the toilet
• Provides warm water, heated seat, air dryer, deodoriser
• Electronic controls (remote or side panel)
• Higher upfront cost; small ongoing electricity cost (~$50/year)
• The Ayora and Arista add auto lid open/close for hands-free operation

For NDIS participants, electric seats with auto lid and warm air drying often best address functional needs. See our NDIS bidet seat guide for detail.

Step 4: Check Seat Dimensions

Before ordering, measure:

• Length from the mounting holes to the front edge of the bowl
• Width at the widest point of the bowl

Compare against the seat's listed dimensions. Most Australian elongated toilets are consistent, but compact or designer toilets can vary. All Conor product pages list dimensions clearly.

Step 5: Confirm Water Pressure Compatibility

Australian residential water pressure runs 150–500 kPa (22–72 PSI), typically 200–350 kPa. All Conor bidet seats are designed and tested for Australian pressure ranges.

Some imported seats are calibrated for different markets. Always confirm pressure compatibility when buying from overseas brands.

Step 6: Assess Installation Requirements

All Conor seats ship with a complete installation kit: T-adapter, bidet hose, and mounting hardware. Installation takes 20–45 minutes for a non-electric seat. For full step-by-step instructions, see our bidet seat installation guide for Australia.

Electric seats follow the same water-connection process, plus plug into a standard power outlet. If you don't have a power outlet near the toilet, an electrician can install a GPO — this is a one-time cost and typically takes less than an hour.

Step 7: Consider Accessibility Needs

For households with elderly residents, people with disabilities, or NDIS participants, specific features matter beyond standard functionality:

• Auto lid open/close — Hands-free operation, no bending or reaching (Conor Ayora, Conor Arista)
• Warm air dryer — Reduces need to manually wipe or reach
• Remote control — Operable from a seated position without side-panel reach
• Heated seat — Comfort for extended sitting periods
