When it comes to bathroom renovations, most people start with tiles, colours or tapware. But before you get too far down the Pinterest rabbit hole, there’s one question you need to ask: do I need building consent?

Jennifer Price, Strategic Brands Manager for Plumbing World, says consent is one of the most common stumbling blocks. If you’re just replacing a vanity or updating tapware, you’re likely in the clear. But if you’re moving plumbing fixtures like the shower or toilet, it’s a different story. “If you’re moving any bathroom fitting, like where the water is coming from or where the water is going out, those are going to require consent.”

Skipping that step can throw out your entire renovation timeline. Consent applications take time, and if your plumber or builder is already booked, delays can quickly stack up. It can also cost you in the long run. Work done without the right sign-off could affect your insurance, council records and even your ability to sell.

The good news is it’s easy to find out if you need consent. Start by talking to your plumber or builder. If they’re unsure, check with your local council before you order anything. It’s much easier to make changes on paper than when the bathroom has already been ripped out. As Jennifer puts it, “You can never start too soon. You can only start too late.”

Jennifer recommends allowing three to four months of planning time before any work starts, especially if you’re making layout changes. That gives you enough breathing room to arrange consent, get expert advice, check product lead times and make informed decisions without rushing.
