What Size Is Your Plug Hole?

Let’s talk about waste. We’re talking basin waste sizes and bath waste sizes—the tiny details that make or break your bathroom's flow.


So, What Even Is a Basin Waste?

A basin waste sits at the bottom of your sink and connects to your plumbing.
The most common size in Australia is 32mm, perfect for most bathroom basins.

Popular Styles:

  • Pop-up waste – Click open and shut. Very modern.

  • Plug & chain – Classic and nostalgic.

  • Flip-top – Stylish and spinny. For the design lovers.

What Size is a Bath Waste?

For baths, it's almost always 40mm. Why? Because baths hold more water, and nobody wants to drain slowly while turning into a prune.

Bath waste options:

  • With overflow – extra safety.

  • Without overflow – sleeker look.

  • Cable-operated – twist-to-open fancy stuff.
