How to Measure Your Toilet for a Bidet Seat: A Melbourne and Australia Guide

Choosing a bidet seat starts with one job: measuring your toilet. A bidet toilet seat sits on top of the toilet you already have, so it needs to match the shape of the pan, the position of the mounting holes and the side your water connection is on. Getting these details right before you choose means the seat lines up properly once it is fitted.

This Conor guide explains how to measure toilet for bidet seat fit, step by step, whether you are looking for a bidet Melbourne homes can use or a bidet toilet seat for anywhere in Australia. It is written for anyone searching for a bidet seat Melbourne bathrooms suit, and the same checks apply to every bidet seat Australia households are looking at, from Sydney to Perth.

Why Measuring Matters Before You Choose a Bidet Seat

Toilets in Australian homes come in different shapes and sizes. Some have a squared-off back, some are rounder, and the distance between the mounting holes and the cistern can vary from one toilet to the next. A bidet seat has a fixed shape and size, so it needs to suit your pan as a whole.

Measuring also helps your plumber, and it is the first step in learning how to measure toilet for bidet seat fit for any bidet seat Australia homes choose. When you know your toilet's shape, measurements and inlet side, your bidet installation Melbourne appointment can focus on fitting the seat rather than working out whether it suits the toilet.

What You Need

You only need a few things for how to measure toilet for bidet seat fit:

•       A tape measure

•       A pen and paper, or your phone to note the numbers

•       Your phone camera to take photos from the top and the side

Lift the existing toilet seat and lid before you start, or remove the seat if it comes off easily, so you can see the pan clearly.

Step 1: Check the Shape of Your Toilet

Look down at the toilet bowl from above.

•       D shape: The back of the pan is straighter and the front is rounded, so it looks like the letter D on its side. Many newer Australian toilets have this shape.

•       O shape: The pan is rounder overall, with a curved back and front. This shape is common on traditional toilet suites.

Conor bidet seats come in both shapes. The Conor Elara Non Electric D Shape Bidet Toilet Seat and the Conor Elara Non Electric O Shape Bidet Toilet Seat are made for each type. If you are not sure which shape you have, the guide What Is a D-Shaped Toilet and How Do You Identify One? explains it in more detail.

Step 2: Measure the Length From the Mounting Holes

Measure from the centre point between the two mounting holes at the back of the toilet to the outer front edge of the bowl. This is one useful length measurement for a Conor fit check, but it is not the only one. On its own, a single length measurement, or the shape of the toilet, does not confirm that a bidet toilet seat will fit.

Write this number down alongside the other measurements in the steps below. Together with your toilet's overall dimensions, the mounting hole position and spacing, and your water inlet side, it gives a fuller picture to compare with the bidet seat product page.

Step 3: Measure the Width of the Bowl

Measure across the widest part of the bowl, from the outer edge on one side to the outer edge on the other. A bidet toilet seat should sit neatly on the rim without hanging over the sides too far or leaving a gap.

Step 4: Measure the Mounting Hole Spacing

Measure the distance between the centres of the two mounting holes at the back of the toilet. These are the holes the bolts of your current toilet seat go through. A bidet seat Australia buyers choose needs to line up with these holes, so this is a key number to check against the product page.

Step 5: Check the Space Behind the Seat

Measure from the centre of the mounting holes back to the cistern or the wall. A bidet seat has a control and connection area at the back, so there needs to be enough room for it to sit and for the seat and lid to lift without hitting the cistern.

Also check the space at the sides of the toilet. If your toilet is close to a wall, vanity or shower screen, make sure there is room for the seat and, on some models, the side control panel.

Step 6: Find Your Water Inlet Side

Look at where the water supply connects to your toilet cistern. Facing the toilet, check whether the water connection is on the left or the right. This tells you whether you need a left or right inlet bidet seat.

A left or right inlet bidet seat has its water connection on that side, which keeps the hose short and tidy. The Conor Elara is available with left and right inlet options, so match the inlet to your toilet before choosing.

Step 7: Check for a Power Point (Electric Models Only)

If you are looking at an electric bidet toilet seat or a smart toilet Melbourne homes can install, look for a power point near the toilet. If you already have a power point within reach, you can plug the seat straight in. If you do not have one, you will need a licensed electrician to install one so the seat has power.

A non electric bidet seat does not need power at all. You can compare both types in the Conor non electric bidet seat collection and the Conor smart bidet seat collection.

Compare Your Measurements With the Product Page

Once you have your numbers, open the product page for the bidet seat you are considering. Conor product pages, such as the Conor Elara pages, ask you to compare your toilet's overall dimensions, the fixing-hole position and spacing, and the water inlet side. No single measurement confirms fit on its own, so compare all of them together:

•       Your toilet's overall dimensions, including the length from the mounting holes to the front edge, against the seat's overall size

•       Your bowl width against the seat width

•       Your mounting hole position and spacing against the guidance on the product page

•       Your water inlet side against the inlet option of the seat

•       The space behind your mounting holes against the depth of the seat's back section

If your numbers are close and you are unsure, send top and side photos of your toilet, along with your measurements, to the Conor team. The team can look at the photos and measurements and help you choose a bidet seat that suits your toilet, whether you are looking for a bidet Melbourne bathrooms can use or a bidet seat Australia wide.

Measuring for a Bidet Seat Melbourne Homes Can Use

Anyone searching for a bidet seat Melbourne homes can use will find that Melbourne has a wide mix of homes, from older weatherboards and terraces in the inner suburbs to newer builds and apartments across the growing outer suburbs. That means there is no single toilet type across the city.

•       Older homes: Many have O shape toilets and cisterns set close to the wall, so check the space behind the mounting holes carefully.

•       Newer homes and apartments: D shape toilets are common, and bathrooms can be compact, so check the side clearance as well as the shape.

•       Renovated bathrooms: Wall-faced and close-coupled toilets can have different mounting positions, so measure the hole spacing rather than assuming.

Whatever kind of home you have, the steps above work for any bidet seat Melbourne or bidet Melbourne search. Take your measurements, note your inlet side, check for a power point if you want an electric model, and compare everything with the product page.

Bidet Installation Melbourne: What to Know

A bidet seat or handheld bidet spray that connects to the household water supply must be installed by a licensed plumber in Australia. Your plumber will check the backflow protection required and fit the seat in line with plumbing requirements and the manufacturer's instructions.

Having your measurements ready makes a bidet installation Melbourne appointment more straightforward. A bidet seat Melbourne plumbers fit follows the same requirements as a bidet seat Australia wide. Share your toilet shape, inlet side and photos with your plumber so they know what to expect.

For any bidet installation Melbourne job involving an electric bidet toilet seat, remember the power point check from Step 7. If you already have a power point near the toilet, the seat plugs straight in. If not, a licensed electrician can install one.

Smart Toilet Melbourne: Measuring for a Full Toilet

Some people searching for a bidet Melbourne option, or comparing a smart toilet Melbourne buyers are considering, are deciding between a bidet seat and a full smart toilet. A bidet seat fits onto your existing toilet. A smart toilet replaces the whole toilet, combining the bowl, cistern and seat in one fixture.

If you are considering a smart toilet Melbourne buyers can choose, the measuring is different. Instead of the bowl and mounting holes, your plumber will check the position of the waste outlet, the distance from the wall to the centre of the waste and the space around the toilet. You can see the full range in the Conor smart toilet collection.

If you want to keep your current toilet, a bidet seat is the option to measure for. If you are renovating and replacing the toilet, a smart toilet Melbourne plumbers can fit may suit the new layout.

Frequently Asked Questions

How do I measure my toilet for a bidet seat in Melbourne?

For any bidet seat Melbourne homes use, check the shape (D or O), then measure the toilet's overall dimensions (including the length from the centre of the mounting holes to the front edge and the width at the widest point), the mounting hole position and spacing, and the space behind the holes. Note your water inlet side and compare all of these together with the bidet seat product page, as shape or one length measurement alone does not confirm fit.

How do I know if I need a left or right inlet bidet seat?

Face the toilet and look at where the water supply connects to the cistern. If it is on the left, choose a left inlet bidet seat. If it is on the right, choose a right inlet bidet seat.

Does a bidet seat in Melbourne need to be installed by a plumber?

Yes. Every bidet installation Melbourne job must be done by a licensed plumber. A bidet seat that connects to the household water supply must be installed by a licensed plumber anywhere in Australia, including Melbourne. This applies to every bidet seat Australia wide.

Do I need an electrician for an electric bidet toilet seat?

Only if you do not have a power point near the toilet. If you already have one within reach, the seat plugs straight in. If not, a licensed electrician needs to install one.

What is the difference between a bidet seat and a smart toilet Melbourne homes can install?

A bidet seat fits onto your existing toilet. A smart toilet replaces the whole toilet with a single unit that includes the bowl, cistern and seat, so it needs different measurements and a full installation.
