Slotted or Unslotted Bathrooms Wastes?

Posted on Thursday 4th July 2019 by Des Roberts


"Which type of basin waste should I get?"

We'll be honest, this isn't the most exciting question that people ask us when remodelling their bathrooms.

But, a waste is a vital part of any properly functioning basin, and no bathroom is really complete without one. So it's worthwhile spending a bit of time making sure you get everything right.

So, without further ado, here is your definitive guide to choosing the perfect basin waste for your bathroom. We will cover:

  • What a basin waste does
  • The types of basin waste you can get
  • What determines the type of basin waste you need
  • How to choose a basin waste
  • The styles you can choose from

We hope you're excited.

What does a basin waste do?

In case you're not familiar with the term, here's a quick rundown...

A basin waste is simply the tube that water drains out of. It's a clear line between your basin and the sewage system, and you block it temporarily with a plug or stopper when you want to fill the basin.

All types of basin will use a waste so that water can drain, and so that the drain can be blocked temporarily when you need to fill the basin.

It may not sound like much, but it's an important piece of bathroom plumbing.

If you have or choose a basin with an overflow and you choose the wrong waste, the overflow may not work as intended. In this scenario, running water that is left unchecked with an overflow that isn't working won't drain properly and may leak all over your floor. Nobody wants that.

(An overflow is the small hole in the back of your basin that water can drain through if the level gets too high.)

What types of basin waste are there?

There are two main types of basin waste: slotted and unslotted.

The slot refers to a small hole in the bit of the overflow that sits below the plug hole. This hole allows water that flows into the overflow to drain away.

So, the answer to the question “do I need a slotted or unslotted basin waste” is fairly simple, as you can see. If you have a basin with an overflow you need a slotted basin waste, and if you have a basin without an overflow you need an unslotted one.

Here's what the same model of basin waste looks like with and without a slot:

This is AquaEco slotted basin waste. See the hole that the red arrow is pointing to?

That means it can be used on basins with overflow.

And here's the AquaEco unslotted basin waste, without the hole.

No hole, meaning it would only be used on basins without an overflow.

How to choose a basin waste

The first step is to choose the basin and taps you want, as this will give you the information you need to determine what type of basin waste you need.

You're looking for two things:

  • Does the basin you want have an overflow?
  • Do the taps you want have a waste built in?

Some tap manufacturers build wastes right into their tap design. Where this is the case, you're saved from the hassle of choosing a separate one.

This is the Burlington Chelsea curved mono basin tap, which we sell. You can see from the schematic that a waste is included in the tap design:

If you go for something like this in your bathroom, you don't need a basin waste. You just have to check the tap you choose is compatible with your basin.

On that last point: this is exactly what our team are trained and qualified to advise on. They will help you to choose the perfect configuration of basin, tap, and waste for your bathroom. They'll tell you what you need and match you with a design to make your bathroom pop.

Which styles of basin waste are there?

If it turns out you do need a to buy a separate basin waste, you have several options of which one to go for.

They are:

  • Plug and chain
  • Click clack
  • Flip top
  • Pop up

The one you choose will depend on personal taste, the style you're going for in your bathroom, and whether you want an exposed or concealed mechanism.

Let's introduce each one.

Plug and chain waste

This is maybe the most recognisable type of basin waste. A chain is connected to a plug, and you block the drain with the plug as and when you need.

The chain prevents the plug from getting lost, meaning this is a simple and elegant design. There's a reason it's stood the test of time.

Here's the Heritage rose gold basin waste to show what we mean:

As we say, this is a favourite for a reason. Familiar, easy to use, and stylish. Just make sure that your basin has a hook to attach the chain to if you go for this option; not all modern basins do.

Click clack waste

The name refers to the sound this type of waste makes when you use it. When you push down on the stopper it pops up or clamps down, with a gentle clack sound.

You may also hear this called a push button waste because it's a bit like pressing a button. Or simply as a click waste, for people who don't have the same to say 'click clack'.

Here's a Pura click clack basin waste to show you what the click clack mechanism looks like. Note that it's concealed, with no visible chain:

We find this design to be quite popular, as it's very simple to use. Just push down and you're good to go!

Flip top waste

With this type of basin waste, the stopper rests on a hinge. It's simple and easy to use; you just push down on one side of the stopper and water can flow down the drain.

This is the Crosswater flip top basin waste, which shows what the mechanism looks like from the outside.

Pop up waste

This type of basin waste is controlled by a small lever that usually sits behind the tap. When you flick the lever from one side to the other, the stopper pops up or down.

Our customers like pop up wastes because you don't have to put your hands in the water to drain the basin. This is great if the water is dirty, has gotten cold, or you just don't want to get your hands wet again after having dried them.

A pop up waste will look something like this. Remember that the tube will be out of sight: you'll only see the silver bits.

That is the Vado vertical basin pop up waste, if you're interested. 

There you have it, hopefully that's everything you need to know about basin wastes, and which type you should get. We've covered all the things you have to consider when choosing a waste; whether your basin has an overflow. Whether your taps have a waste built in.

We've also covered the different types of basin waste available so that if you do need one, you can choose the most stylish and suitable for your bathroom.
