How to Measure Bathtub Drain Plug Size in mm

Measuring the size of your bathtub drain plug in millimeters (mm) is crucial for ensuring a perfect fit when replacing it. Here's a comprehensive guide to help you measure the drain plug accurately.

Materials you'll need:

Measuring tape or ruler in millimeters
Flashlight (optional)

Steps:

Remove the existing drain plug:
Use a drain plug wrench or pliers to gently remove the drain plug. If the plug is stuck, you may need to use a penetrating oil or lubricant to loosen it.
Measure the diameter of the drain hole:
Place the measuring tape or ruler across the opening of the drain hole. Ensure the tape is perpendicular to the hole. Measure the distance between the two edges of the hole to determine the diameter.
Determine the length of the plug:
Use the flashlight to illuminate the inside of the drain hole. Measure the distance from the top of the hole to the bottom of the threads or the lip of the drain plug. This measurement determines the required length of the replacement plug.
Note any additional features:
Check for any additional features on the drain plug, such as a lift-and-turn mechanism or a rubber gasket. Make sure to measure these features accurately, as they may affect the fit of the replacement plug.
Convert to millimeters:
If your measurements are in inches, convert them to millimeters by multiplying by 25.4. For example, a 1-inch drain hole would be 25.4 mm in diameter.

Tips:

Ensure the drain hole is clean and free of debris before measuring.
Use a measuring tape or ruler with clear markings for accurate readings.
If the drain hole is not perfectly round, measure the diameter at the widest point.
When selecting a replacement drain plug, choose one with a slightly smaller diameter than your measurement to ensure a snug fit.

By following these steps, you can accurately measure the size of your bathtub drain plug in millimeters, ensuring a seamless and effective replacement.
