How to Measure Bathroom Sink Drain Size
Replacing a bathroom sink drain is a relatively simple plumbing task that can be completed in a few minutes. However, it is important to measure the drain size correctly before purchasing a new one. Otherwise, the new drain may not fit properly and could cause leaks.
There are two main types of bathroom sink drains: pop-up drains and lift-and-turn drains. Pop-up drains are the most common type and are opened and closed by pressing on a button or lever. Lift-and-turn drains are opened and closed by turning a knob or handle.
To measure the size of a bathroom sink drain, you will need a tape measure or a ruler. First, determine the type of drain you have. Then, follow the steps below:
Pop-Up Drains
- Measure the diameter of the drain opening. This is the distance across the widest part of the opening.
- Measure the length of the drain body. This is the distance from the top of the drain opening to the bottom of the drain body.
- Measure the diameter of the drain flange. This is the distance across the widest part of the flange.
Lift-and-Turn Drains
- Measure the diameter of the drain opening. This is the distance across the widest part of the opening.
- Measure the length of the drain body. This is the distance from the top of the drain opening to the bottom of the drain body.
- Measure the diameter of the drain flange. This is the distance across the widest part of the flange.
- Measure the distance between the drain opening and the center of the overflow hole. This is the distance from the edge of the drain opening to the center of the overflow hole.
Once you have measured the drain size, you can purchase a new drain that is the same size. It is important to make sure that the new drain is the correct type for your sink. Otherwise, the drain may not fit properly and could cause leaks.
If you are not sure how to measure the bathroom sink drain size, you can consult with a plumber. A plumber can help you measure the drain size and choose the correct replacement drain.
