Choosing the right waste & trap

What waste and trap

After you have chosen the basin to match your bathroom and furnishings, the next step is to decide upon a tap, waste and trap. We would recommend deciding upon your tap before choosing a waste because a vast number of taps come complete with a waste. Take a look at our Bathroom Taps guide for inspiration and further guidance.

What is a waste?

Every basin will require a waste, whether it’s a wall hung or countertop basin. Wastes are designed to fit within the main standard 45mm hole found in your basin and act as a channel for the waste water to run away. They act as a barrier to foreign objects blocking your pipes and also double up as a stopper so your basin can be filled for those daily routines.

Slotted or unslotted?

A common misunderstanding is ‘what type of waste do I need?’. All wastes are a standard size and will fit all basins. The most important selection is to ensure you choose a slotted or unslotted version according to the basin you have. Simply, where a basin is specified to include an overflow (which is integral to the basin unlike a kitchen sink) you will require a slotted waste. Those basins without an overflow should be fitted with an unslotted waste. This is important because a slotted waste will not fit a basin without an overflow, and vice versa. At Splash Direct we ensure that your selection is effortless by identifying in the basin’s specification whether it has an overflow or not.

The types
We have a vast array of wastes you can choose from:

  • The Plug and Chain Waste. The most traditional form of waste increasingly losing its status to more modern designs. The classic plug and chain which is fairly straight forward to use. A plug (either plastic or metal) that is connected to a chain that simply covers the waste hole when required. You may find on modern basins that there is no hole for the chain stay to be fitted, so confirm this before making your decision.
  • The Push Button Waste. Also known as the ‘click clack’ or ‘sprung plug’ waste, these are operated by pushing the domed stopper once to close and again to open. This is fast becoming the most popular waste available due to its simple design and easy operation.
  • The Flip Top Waste. Controlled by rotating the disc type stopper hinged on two sides vertically to allow the water to flow through, or flat to act as a barrier. Again simple to use and minimalist in its design.
  • The Pop Up Waste. Conventional and still going strong, the pop up waste has been around for some time and works with the use of a lever operation. The lever is pulled up to lower the waste stopper, or pushed down to raise it. Largely incorporated in the back of a tap, the pop up lever protrudes through a small hole in the back. Don’t be afraid, however, to use a different type of waste with a tap that has a pop up. Simply do not fit the pop up lever on the tap, and the small discrete hole out of sight can be filled with sealant to stop any water from running to the underside of the basin.
  • Free Flow Waste. Also known as a ‘free running waste’ these wastes are for those who opt for shallow basins or basins with no overflows. Manufacturers would recommend using this choice of waste to allow for the constant flow of water and the prevention of the basin filling up, which could potentially cause a flood.

Bottle traps

A necessity for all basins, the bottle trap doubles up as a seal to stop smells backing up from waste pipes, and allows the body to be unscrewed for cleaning purposes. Available in various finishes and shapes, all bottle traps are a standard fitting and are screwed to your chosen waste from the underside of your basin. Two types of basin bottle trap exist. These are the ‘P-Trap’, which is the most common form and used when the waste pipe is projecting through the wall, and the ‘S-Trap’ – not as widespread, but used when your waste pipe is projecting vertically through the floor.

Take your time looking through our selection of bottle traps and decide upon one that will best suit the style of basin and tap you have.
