How to Fit a Basin Waste

A quick and simple way to freshen up your bathroom's style - Find out here how to fit a new basin waste.

If you glance at the image above, can see that that a basin waste is a part of a sink, usually in a bathroom, that lets water flow out while also giving you the option to block the sink to keep water in. It fits into the drain hole and directs water to the pipes. Basin wastes come in different types to match different styles and needs.

A crucial but often neglected bathroom component, basin wastes allow you to fill your basin and easily empty it whenever you need to.

Now available in a wide range of designs, basin wastes are easier to install than ever before. To highlight this, we’ve put together a handy ‘how-to’ in order to teach you just how easy fitting a basin waste yourself is.

Why Should You Replace Your Basin Waste?

Though you’re unlikely to have given your basin waste much thought, it could be having a negative effect on your bathroom’s style. Wastes are prone to buildups of limescale and black mould that can be tricky to remove.

In severe cases, wastes can even become caked in rust. For obvious reasons, this isn't a good look to have in a space where cleanliness is key. So, if a deep clean doesn’t do the trick a new basin waste should be on the cards.

Older wastes, particularly those with a traditional pop-up basin waste, can be prone to mechanical failures. In these cases, we suggest replacing it with a modern ‘click clack’ waste.

Basin waste replacement can also serve to make your bathroom more aesthetically pleasing. If you’ve recently made the upgrade to matte black taps, for example, a matching matte black basin waste can harmonize the look and bag you some extra style points!

You’ll need:

• A bucket

• A set of pliers

• A cleaning cloth

• A screwdriver (optional)

1. Turn Off Your Water Supply

Just a quick precautionary measure to ensure you don’t flood your bathroom. Simply switch off the valve for your home’s supply (this is likely to be found underneath the sink).

2. Unscrewing Your Basin Trap

Place your bucket directly underneath your basin’s trap. Next, take your pliers to your trap and lightly loosen your trap from your waste until you are able to unscrew it by hand. Once the trap is disconnected, be sure to keep hold of its rubber seal; if you lose this you’ll need to replace it with a suitable O-ring.

3. Detaching Your Waste

Next, unscrew the large hexagonal nut securing your waste to the basin. Then, remove the waste’s rubber seal before detaching the waste completely. If the waste was sealed using large amounts of silicone you may need to use a screwdriver to gently pry it free.

4. Clean-up

Take a hot, wet cleaning cloth and scrub away any remaining silicone residue.

How to Fit a Basin Waste in 5 Simple Steps

You’ll need:

• A suitable basin waste (check out our guide to basin wastes if you’re unsure)
• A silicone sealant gun
• A quality silicone sealant

1. Clean the Surface

Making sure the surface of your sink plughole is clean and dry before fitting your waste is an important step. Wipe down the surface with a cloth to ensure the waste fits well. 

2. Place Waste in Plughole 

Firstly, make sure that your rubber washer is pushed to the top of the waste before placing it in your plughole. Ensure that you place the waste directly in the middle of the plughole to guarantee a perfect fit. 

3. Seal the Bottom of the Basin

Go beneath the basin to find the bottom of the basin waste. Next, take your rubber seal, making sure the flat side up is facing down, and, whilst holding the top of the basin waste, push it into the bottom of the basin waste. Push the seal to the top of the waste so that it meets the bottom of the basin. 

5. Attach the Retaining Nut

Next, screw the hexagonal nut on tightly, making sure to simultaneously put pressure on the top side of the waste to stop it from spinning.

6. Fit the Trap

After you have screwed on the nut, fit the trap onto the bottom of your waste. Afterward, connect the pipes underneath, at the back of your waste, and you're all set!
