Installing a new bathroom sink waste plug can be a straightforward process, but you must first determine the type of waste plug required and ensure you have the right tools for the job. Our guide will go through the process of installing a waste plug, providing you with the steps to fit your new one with ease.

Know which sink waste plug you need
Perhaps your current waste plug is damaged, or you want to switch the colour to suit a new sink. You might even have a sink waste plug with the new basin to install. Regardless of reasoning, before you do anything, figure out which waste plug you need for your basin. The four main types are as follows:
- Non-slotted waste
- Slotted waste
- Gated waste
- Freeflow waste
You can find out more about the different types via our waste plug guide. Once you have the correct type, whichever waste is in your possession, each should have a top seal, a bottom larger seal and a black fixing nut.
Fitting a sink waste plug
You can fit a waste plug in some short, simple steps. Before you start, you will need:
- Waste plug
- Silicone sealant
- (If applicable) Bottle trap
Onto the fitting!
Step one: Prepare the waste plug
Remove the larger seal and the fixing nut from the threaded shaft. Only the thinner seal should remain on the waste.
Step two: Insert the waste plug
Ensure the thinner top seal is cupped upwards on the waste, then place it in the hole of the basin. Slotted wastes will have two holes and need to line up with the internal overflow holes in the basin. Make sure it is not blocked.
Note: Applying a silicone sealant inside the basin before slotting in the waste can create a watertight seal where the plug sits.
Step three: Fit the second washer
After fitting the waste into the basin, which could be through the countertop, fit the second washer to the waste. Fit it from underneath the cabinet, making sure it is cupped upwards.
Note: Apply a second bead of silicone for a more watertight solution if needed.
Step four: Secure the waste in place
Secure the waste to the basin by hand-tightening the black fixing nut, being careful not to overtighten, else this can risk damaging the plug.
Step five: (If applicable) Fit the bottle trap
Fit a bottle trap to the waste and wipe away any silicone sealant with a cloth.
And there you have it! The simple process needed to fit in your new sink waste plug.
