How much does new toilet installation cost?
When replacing a toilet, you’ll also need to account for plumber rates, which usually range from $250 to $400 for basic toilet installations. On average, toilet replacement installations fall between $300 and $500. If plumbing needs to be modified, expect costs to start from around $400. Installing a toilet in a new location is a much bigger job and can cost $1,500 to $3,500 or more, depending on the extent of the plumbing work required.
If you’re installing an in-wall cistern, which hides the cistern behind the wall, the job may be more expensive due to the extra work involved, usually making it costlier than standard installations. Installing a wall-hung toilet, which has an in-wall cistern, can cost $1,200 to $2,500+.
Typically, plumbers charge on an hourly basis, ranging from $100 to $150 per hour. Since installing toilets is a routine job for most plumbers, many will offer upfront quotes to ensure you know the total cost. The average installation time is between two to four hours.
To reduce costs, it’s worth checking with your local council to see if any rebates are available for replacing older toilets with newer, water-efficient models.

Common signs replacing a toilet is necessary
Wondering if it’s time for a new toilet? Here are a few common signs that indicate you might need a replacement:
- A Running Toilet: If your toilet constantly runs, it could be due to a broken valve or flapper. While this can sometimes be fixed with a simple repair, if the problem persists, it may indicate deeper issues that require a new unit.
- Frequent Clogging: A toilet that clogs regularly can signal worn-out internal components. If your toilet is new and still experiencing clogging problems, it’s important to have a licensed plumber inspect both the toilet and plumbing to prevent ongoing issues.
- A Wobbly Toilet: A wobbly toilet can often be fixed by tightening the screws. However, if it continues to move, there might be an underlying problem with the floor or the toilet’s base. In such cases, it’s best to consult an experienced plumber to diagnose and resolve the issue.
If any of these issues are affecting your toilet, it may be time to consider a replacement rather than ongoing repairs.

Water efficiency and WELS ratings
In Australia, WELS (Water Efficiency Labelling and Standards) ratings measure toilet water use per flush. Most modern toilets meet the four-star standard, using about 4.5 litres for a full flush and 3 litres for a half flush. Higher-rated models use even less water, reducing household consumption.
Dual flush toilets are now the standard and allow a half flush for liquid waste and a full flush for solids. This cuts water use compared to older single flush systems. Upgrading to a dual flush toilet can save on water bills over time, offsetting replacement costs.
Toilets can also be connected to a rainwater tank, substituting mains water for flushing and further lowering household water use. Choosing WELS-rated toilets supports both water efficiency and environmental sustainability.
WELS Toilet Ratings and Water Usage
| WELS Star Rating | Full Flush (L) | Half Flush (L) | Typical Savings vs Single Flush |
|---|---|---|---|
| 3 Star | 6.0 | 3.5 | Moderate |
| 4 Star | 4.5 | 3.0 | Significant |
| 5 Star | 3.5 | 2.0 | High |
| 6 Star | 3.0 | 1.5 | Maximum |

What type of toilet installation do you need?
When replacing a toilet, you can choose from several toilet suite styles, each offering different aesthetics and functionality:
- Wall-Hung Toilets: These toilets are mounted on the wall, creating a minimalist and sleek look. They come with an in-wall cistern, which is hidden behind the wall, offering a clean, modern appearance and saving space.
- Wall-Faced Toilets: This type has a base that’s fixed to the floor, similar to traditional toilets, but it also features an in-wall cistern. The design provides a streamlined, modern look while concealing plumbing.
- Back-to-Wall Toilets: These toilets sit flush against the wall, offering a more contemporary or European style. The cistern is either built into the wall or positioned behind the unit, hiding all visible pipes for a tidy, streamlined design.
- Close-Coupled Toilets: This is the most common and cost-effective type of toilet. The cistern and pan are joined together as one unit, with the cistern positioned directly on top of the toilet pan. It’s a traditional design that’s simple to install and maintain.
Your choice depends on factors like aesthetic preference, space constraints, and budget. Each type has its pros and cons, but they all provide functional and modern solutions for your bathroom.

What kind of existing toilet outlet do I have?
When selecting a new toilet suite, it’s important to consider the existing plumbing in your bathroom, as this will determine which type of outlet your new toilet needs. If you don’t want to alter your plumbing, you’ll need to match the outlet type of your old toilet.
There are two main types of toilet outlets:
- S Trap Outlet: This type of outlet has plumbing that runs through the floor. If your current toilet connects to the floor with a pipe running directly underneath, you likely have an S trap outlet.
- P Trap Outlet: This type has plumbing that runs through the wall. If the pipe from your toilet connects to the wall, you have a P trap outlet.
To identify which you have, simply check if the toilet’s plumbing connects to the wall (P trap) or floor (S trap).
If you have an S trap but want to replace it with a toilet that has a P trap outlet, keep in mind that you’ll need to factor in the additional materials and labour costs for modifying the plumbing during installation.

Frequently Asked Questions: Toilet Replacement Cost Guide
The cost to replace a toilet typically ranges from $600 to $1,000 or more. This depends on factors such as the type of toilet you choose and whether any plumbing modifications are required.
In most cases, repairs are cheaper upfront, especially for minor issues like a faulty flush valve, leaking seal, or running cistern. These fixes typically cost $100 to $300. If the toilet is older, frequently breaking, or cracked, replacement is often more cost-effective long term. A new toilet can improve water efficiency and reduce ongoing repair costs.
Plumbers in Australia typically charge between $100 and $150 per hour, depending on location, experience, and the type of job. Many plumbers also charge a call-out fee of $60 to $150, which may include the first hour of labour. After-hours or emergency work can cost significantly more.
Toilet installation can be expensive because it involves more than just fitting the unit. A licensed plumber is required to ensure proper connection to the water supply and sewer system, along with correct sealing and compliance with Australian standards. Costs may also include removing the old toilet and making adjustments to existing plumbing, which can increase the overall price.
Yes, but if you have an S trap and want to install a P trap toilet, it will require additional materials and plumbing work, which can increase the overall installation cost.
Most toilet installations take between two to four hours, depending on the complexity of the job. A plumber will often give an upfront quote based on the work involved.
While installing a basic toilet might seem straightforward, it’s generally recommended to hire a licensed plumber. They can ensure proper installation, check for leaks, and address any plumbing issues, particularly if you need to move plumbing or install a more complex system like an in-wall cistern.
For small bathrooms, consider a wall-hung toilet or back-to-wall toilet. Both types help create a more spacious, streamlined look by concealing the cistern and saving floor space. Compact close-coupled toilets can also work well in smaller spaces.
