What are the different size of sink and bath plugs?

Sink plugs are essentially made to do just one job – plug the sink. Many people assume that all sinks have the same size of plug hole but this is not always true.

The most common sizes for a sink plug hole are 1.75″ and 1.5″, although due to clarity on what the actual “standard” is, you may well find that you have a completely different size fitted.

However, if you aren’t sure what size your existing or new sink has, there is a multitude of ways to find out.

How to measure a sink (or bath) plug

Measuring the size of a sink or bath plug hole is simply done by measuring the diameter of the plug hole. Here are a few methods you could use to accurately measure the size of your sink plug hole.

Method 1: Take a Tape Measurer

Take a tape measure and measure the circumference around the plug hole in millimeters or inches.

Method 2: Remove the Plug

If you have an existing or new sink that has already been installed, remove the drain/plughole and measure it.

Method 3: Look at Your Fixtures

If you are in the process of purchasing a new sink or already have one in place, look at the fixtures that come with your sink. The measurements will be clearly labeled on them making it extremely easy to measure the size of your plug.

Method 5: Use a Piece of String

If you don’t have any fixtures or an existing drain/plughole to take measurement from, tie a piece of string around your new plug and measure it after putting it through the drain.

Should I get a new sink plug?

There are several reason why you might need a news sink plug. One of the most common reasons is that the chain has broken. This can sometimes be fixed with a pair of pliers but sometimes its easier just to buy a new plug.

Plugs can also get damaged from rust, which is a very common problem with cheaper plugs. The metal finishes on these types of products are less durable and more prone to chipping or cracking eventually if left untouched

However, if your plug is in good condition with no cracks or chips and continues to do its job perfectly well, there is no need to change it.


As mentioned above, if you are not sure about the size of your sink plug hole you can check it at any stage.

If you do decide to change it however, home improvement stores like B&Q and Wickes will have a wide range of different types available.
