The size of your bathtub drain is determined by the diameter of the drain opening. The most common bathtub drain sizes are 1 inches, 2 inches, and 2 inches.

To determine the size of your bathtub drain, you need to measure the diameter of the drain opening. You can do this by using a ruler or tape measure. Once you have the measurement, you can compare it to the size chart below to find the right drain for your bathtub.

What Type of Bathtub Drain Do I Need?

There are two main types of bathtub drains: overflow drains and no-overflow drains.

  • Overflow drains have a small overflow pipe that runs along the top of the bathtub. This pipe helps to prevent water from overflowing the bathtub if it gets too full.
  • No-overflow drains do not have an overflow pipe. These drains are typically used in bathtubs that have a built-in shower.

The type of bathtub drain you need depends on the type of bathtub you have. If your bathtub has an overflow pipe, you will need an overflow drain. If your bathtub does not have an overflow pipe, you can choose either a no-overflow drain or an overflow drain.

What Style of Bathtub Drain Do I Want?

There are a variety of different styles of bathtub drains available, including:

  • Pop-up drains are the most common type of bathtub drain. They have a small cover that pops up when you drain the water.
  • Strainer drains have a metal or plastic screen that catches hair and other debris.
  • Linear drains are long, narrow drains that are installed along the bottom of the bathtub.

The style of bathtub drain you choose is a matter of personal preference. Some people prefer pop-up drains because they are easy to use and clean. Others prefer strainer drains because they help to catch hair and other debris. Linear drains are a good option for bathtubs with a lot of jets because they allow water to drain quickly.
