Are Bathtub Faucet Stems Universal? Here’s The Truth!

When it comes to bathtub faucets, one of the most common issues that homeowners face is a leaky stem. While replacing a faucet stem may seem like a daunting task, it is actually a relatively simple and inexpensive repair that can be done in a matter of minutes. However, before you start shopping for a new stem, it is important to know whether or not bathtub faucet stems are universal.

Are Bathtub Faucet Stems Universal?

The answer to this question is both yes and no. There are some universal bathtub faucet stems that will fit most faucets, but there are also some faucets that require specific stems. To determine if a stem is universal, you will need to look at the spline count and the length of the stem.

Spline Count

The spline count is the number of teeth on the stem. Most universal stems have a spline count of 20, but some faucets may require a stem with a different spline count. To determine the spline count of your faucet, you will need to remove the old stem and count the number of teeth.

Stem Length

The stem length is the distance from the base of the stem to the tip of the stem. Most universal stems have a length of 2-1/2 inches, but some faucets may require a stem with a different length. To determine the stem length of your faucet, you will need to measure the distance from the base of the old stem to the tip of the stem.

Other Considerations

In addition to the spline count and stem length, there are a few other factors to consider when choosing a bathtub faucet stem. These factors include:

• The type of faucet: There are two main types of bathtub faucets: compression faucets and cartridge faucets. Compression faucets use a stem to control the flow of water, while cartridge faucets use a cartridge. The type of faucet you have will determine the type of stem you need.
• The brand of faucet: Some faucet brands use proprietary stems that are not interchangeable with other brands. If you have a specific brand of faucet, you will need to make sure that you choose a stem that is compatible with that brand.
• The age of faucet: Older faucets may require a different type of stem than newer faucets. If you have an older faucet, you may need to consult with a plumber to determine the correct type of stem.

How to Replace a Bathtub Faucet Stem

Once you have chosen a new bathtub faucet stem, you can follow these steps to replace the old stem:

1. Turn off the water supply to the faucet.
2. Open the faucet to release any remaining water.
3. Remove the handle from the faucet.
4. Use a wrench to loosen the packing nut.
5. Pull the old stem out of the faucet.
6. Insert the new stem into the faucet.
7. Tighten the packing nut.
