What's the standard height of a bathroom sink waste pipe connection?
Find out if there's a standard height for a bathroom sink waste pipe connection in this quick read.

There is no standard height for a bathroom sink waste pipe connection. However, it goes without saying that a waste pipe needs to be on a suitable downhill gradient!

The height of your bathroom sink waste pipe connection depends on:
How high the bathroom sink is
Where the trap (the pipe that takes the wastewater away) needs positioning
The latter will be influenced by the set-up of your bathroom sink. For example:
If the sink is surrounded by a vanity unit, the waste pipe will be fitted within the cupboard at the optimal height for the fall of the water
However, if the sink is standalone, the waste is usually fitted as close to the underside of the sink as possible in order to keep everything looking neat
A waste pipe is typically fitted and then cut down to the required height once all the measurements are made.
