bathroom renovation permit

A bathroom renovation can be an expensive undertaking, so it’s vital to ensure that all the right boxes have been ticked legally before beginning your project. Failure to do so could result in costly delays, fines, or even being forced to undo completed work.

In some cases, unapproved renovations can also impact your ability to sell the property down the line or make insurance claims if something goes wrong.

So, do you need a permit to renovate a bathroom in Mandurah? We get asked this all the time at Mandurah Tile & Stone, and the truth is: it’s not always black and white.

So here’s what you need to know before getting started.

When Permits Are Required

If your bathroom renovation involves anything more than cosmetic updates, it’s best to contact the City of Mandurah for approval.

Structural changes, like knocking down or adding walls, or anything that affects plumbing or electrical systems, typically trigger the need for a building permit.

This includes things like:

  • Moving your shower, toilet, or bath to a new position
  • Installing a larger window or changing its location
  • Adding or changing electrical circuits
  • Rebuilding waterproofed areas like showers from scratch

These may affect your home’s compliance with WA building codes and safety standards, which is why it is better to err on the side of caution.

What Bathroom Renovations Can Be Made Without a Permit

There’s still plenty you can update without going through formal approvals, especially if you’re sticking to the existing layout.

Swapping out tapware, replacing a vanity with a similar model, or giving the space a fresh coat of paint doesn’t usually warrant council involvement.

You can also generally re-tile your bathroom, provided you’re not altering the waterproof membrane underneath.

But again, even “simple” jobs can have hidden compliance risks, so it’s always worth double-checking with the council before assuming you’re in the clear.

What the Application Involves

If your renovation does require a permit, you’ll need to lodge an application with the City of Mandurah.

This includes submitting plans, property details, material specs, and paying a fee. For straightforward projects, approvals usually come through within 2–3 weeks, but more complex designs can take longer.

We always recommend building in extra time for this process so you’re not left waiting with a half-demolished bathroom.

Why Skipping Permits Can Be More Expensive in the Long Run

We get it. No one loves paperwork, but going ahead without the right permits can cause bigger headaches later on. Council penalties, complications with insurance claims, or being forced to redo non-compliant work are just a few of the risks.

If you plan to sell your property down the line, unapproved work can also delay or derail the sale process.

The Role of Licensed Tradies

Even if your project doesn’t need a building permit, plumbing and electrical work must still be done by licensed professionals. These tradespeople issue compliance certificates that are critical for your property records and for peace of mind.
