1. It’s Constantly Running, Leaking, or Wasting Water
If your toilet never stops running, leaks around the base, or you’re noticing higher water bills, it’s not just an annoyance – it’s costing you money. Old or faulty cisterns, worn-out seals, and outdated flush mechanisms are common culprits. Modern toilets are designed to be water-efficient, saving you money and helping the environment.
- Why it matters: Wasted water adds up fast. New toilets with dual-flush or low-flow technology use as little as 4.5L per flush, compared to 12L or more in old models.
- What to do: If repairs haven’t fixed the problem, it’s time to buy a new toilet.

2. Cracks, Chips, or Stains You Can’t Clean
Porcelain is tough, but not invincible. Cracks in the bowl or cistern, chips in the enamel, or stains that never disappear are all signs your toilet is past its prime. Cracks can lead to leaks and even structural damage to your bathroom.
- Why it matters: Water leaking from cracks can damage floors and subfloors, leading to expensive repairs.
- What to do: Don’t risk it – replace your toilet before a small crack becomes a big problem. Consider a new toilet with a durable, easy-clean finish.
3. It’s Uncomfortable or Outdated
If your toilet seat is wobbly, uncomfortable, or the wrong height, it’s time for an upgrade. This is especially true if your household includes children, elderly family members, or anyone with mobility needs.
- Why it matters: Comfort and accessibility are non-negotiable. New toilets come in a range of heights and styles, including options that meet disabled toilet standards in Australia.
- What to do: Upgrade to a new toilet seat or a full toilet suite that fits your needs.
Shop new toilet seats and accessible toilets for peace of mind.
4. Repairs Are Adding Up (or Parts Are Hard to Find)
If you’re constantly calling a plumber or hunting for replacement parts, like a new toilet cistern, flush valve, or seat, it’s time to consider the cost of ongoing repairs versus a full replacement.
- Why it matters: Frequent repairs can quickly exceed the cost of a new toilet, especially when you factor in labour and downtime.
- What to do: Compare the cost to install a new toilet with your recent repair bills. Most homeowners find that a new model pays for itself in reliability and efficiency.

5. Your Bathroom Needs a Style or Layout Refresh
A tired, yellowing toilet can drag down the look of your whole bathroom. If you’re renovating, upgrading other fixtures, or just want a fresher space, a new toilet is a quick win.
- Why it matters: Modern toilets come in a range of shapes, colours, and finishes to match any style, from classic white toilets, to minimalist wall-hung toilets, to sleek back-to-wall designs.
-
What to do: Coordinate your new toilet with matching basins, vanities, and bathtubs for a designer finish.

6. You Want to Save Water (and Money)
Australia’s water efficiency standards have improved dramatically. If your toilet doesn’t have a WELS rating or is more than 10 years old, you’re likely flushing money down the drain.
- Why it matters: New toilets can cut your water use by 50% or more, according to the Australian Department of Climate Change, Energy, Environment and Water. Look for models with a 4-star WELS rating for maximum savings.
- What to do: Upgrade to a water-efficient toilet from Buildmat and check out dual flush options.

How to Install a New Toilet (and When to Call a Pro)
Thinking of a DIY Toilet Installation?
Replacing a toilet isn’t difficult if you have some plumbing knowledge, but it does require the right tools. Here’s a quick overview:
- Turn off the water and drain the old toilet.
- Remove the old unit (unscrew bolts, break the seal, and lift away).
- Install the new pan and cistern, ensuring a good seal and level fit.
- Connect to the water supply and test for leaks.
Of course, this is a very basic explanation, so if you’re unsure, it’s always best to call a licensed plumber. Australian standards are strict, especially for ambulant toilet installations.

New Toilet FAQs
What are the new disabled toilet standards in Australia?
Australia’s updated AS 1428.1 standards require toilets to meet specific guidelines for accessibility, including a seat height of 460–480mm, clear space for wheelchair access, correctly positioned grab rails, and easy-to-use flush controls. If you're renovating or installing an accessible toilet, make sure it complies. You’ll find compliant options in Buildmat’s ambulant toilet range.
How do I choose the right toilet for a small bathroom?
Look for compact, back-to-wall, or wall-hung toilets – they save space and make cleaning easier. Measure carefully to ensure there’s enough clearance for use and door swing.
Can I replace just the toilet seat or cistern instead of the whole toilet?
Yes, if your toilet is in good condition and compatible, you can swap out just the seat or toilet cistern. It’s a quick, cost-effective update. But if it’s old, leaking, or cracked, a full replacement is often the better long-term choice.
How can I tell if my toilet is water-efficient?
Check the WELS rating – modern toilets with 3 or 4 stars are the most efficient. Dual-flush models are also a good sign. If your toilet is older or has a single flush, upgrading can cut water use and lower your bills.
What’s the difference between a rimless toilet and a standard toilet?
Rimless toilets use a direct-flush system that cleans the bowl more effectively and reduces bacteria build-up. Standard toilets have a closed rim, which can trap grime. Rimless models are easier to clean and more hygienic.
Do I need council approval to install a new toilet?
Not usually for a straight swap. But if you’re changing the layout, adding a new toilet, or moving plumbing, check with your local council or a licensed plumber to make sure it’s approved.
How do I dispose of my old toilet?
Contact your local council for hard rubbish or recycling options. Many plumbers include removal in their installation service. Don’t dump it, porcelain can often be recycled.
Can I install a bidet or smart toilet seat with my new toilet?
Yes, as long as your toilet is compatible. Some models need additional plumbing or power points, so check the specs before buying.
