Sizes of sink plugs and are they all the same?

Most new constructions now-a-days have a pop-up stopper in your sink. It is something you take for granted but notice it when it is missing. Whether you are giving a bath for the kids or washing dishes in the sink.... the sink plug is not one of the most essential things in your plumbing until you need it!

So what size of sink plug do I get?

Whether you are looking for a sink plug for your sink, bath, laundry, tub or even your caravan, we got the size to help.

To determine the size of your sink plug, you can measure the diameter of the drain mesh or the underside of your current plug using a measuring tape or even a ruler! This will ensure you choose the right size of the sink plug in addition to the style!

In the kitchen and bath the standard size in Australia for the plug is 1 3/4 inch. For bathroom vanities the standard size is 1 1/2 inch.

Suppliers also manufacture the good old days where sizes were different , so sink plugs are still available in: 1 inch, 1 1/4 inch, 1 3/8 inch, 1 5/8 inch, 1 7/8 inch, 2 inch, 2 1/4 inch, 2 3/8 inch and 2 1/2 inch sizes.

Here are the sink plug sizes for the different uses in Australia,

The kitchen and bathroom need to shift and disperse a larger quantity of water as opposed to the bathroom vanity. As a consequence have larger drain holes and outlets. This explains the larger sink plug sizes for the above.

One of the most common questions we get asked about sink plugs is

Why is my kitchen sink plug leaking when the sink is full of water?

If you notice the water level in your kitchen sink going down while you are soaking the dishes - this could be due to multiple factors.

Usually there are three main reasons for the water leaking -

    • The combination sink strainer/ sink plug has been "bumped" and loosened - With a sink full of dishes and water it is quite easy for the movement to bump the combination strainer and sink plug. This causes the rubber seal at the base of the sink strainer to loosen up and start leaking water. It might be worth your while to check if this is the case and ensure your sink plug is sitting correctly against the waste pipe.
    • Worn rubber washer in a sink strainer/ sink plug - It is common for the rubber washer underneath the sink strainer to wear out after extended use. If this is the case you will notice the water leaks even if you "re-adjust" the sink strainer in multiple positions. Save your time, water and money - here is a great sink strainer sink plug for your kitchen sink.
      • Water leak through the waste outlet - This is a scenario where the water is leaking out the waste outlet and your sink plug is fine. A leaking waste pipe can be hard to notice. Especially since the water isn't under pressure and is simply shifted, the leak may not be obvious. You will possible need to visually inspect the area and check of evidence of dripping, wet spots or water. This could mean the sink is not fitted correctly or the waste pipes are too long or short! If this is the case get it fixed straightaway. Water leaks tend to damage adjacent structures and possibly cause mold.
