The pop up waste is a popular and modern fitting designed to elevate your bathroom by creating a cohesive and luxurious aesthetic throughout the interior. But how do you choose the right pop up waste for your basin (or bathtub)? What is the difference between a pop up waste with or without an overflow?

How to choose the right pop up waste?

l Pop up waste size. The most important measurement to know when choosing a pop-up waste is whether the basin waste is 32mm or 40mm. It’s quite common for a basin waste to be 32mm in diameter. The specification sheet will advise what size the waste outlet needs to be.

l Do you need a pop up waste with overflow? An overflow is the small hole in the basin (or bathtub) which is located near the top lip of the product. The hole allows water to drain away in the event the basin is overfilled. Hence the name - overflow!

Basins with an overflow hole must have a pop up waste with an overflow.

An overflow pop up waste can be distinguished by a rectangular hole below the lip of the pop up flange. This overflow hole creates a seamless connection for water to flow through to the basin waste.
