Bathtub Drain Replacement: Your Questions Answered

Here are some frequently asked questions regarding bathtub drain replacement to help you complete the DIY project with confidence.

What tools do I absolutely need for bathtub drain replacement?

Besides the new drain assembly, you’ll need a few essential tools. These include a screwdriver (usually flathead), pliers (channel locks are helpful), plumber’s putty, penetrating oil, and a drain wrench (also called a bathtub drain removal tool). A rag or towel is also useful to protect the tub surface.

How do I loosen a stubborn or stuck bathtub drain?

Penetrating oil is your best friend! Apply it liberally around the drain flange and let it sit for at least 30 minutes, or even overnight. You can also try gently tapping the drain with a hammer and screwdriver to help break the seal. Be careful not to damage the tub. If it still won’t budge, you may need to apply heat with a heat gun (use caution!).

How important is plumber’s putty in bathtub drain replacement?

Plumber’s putty is crucial for creating a watertight seal between the new drain flange and the bathtub surface. Without it, water will leak around the drain, potentially causing damage to your bathroom floor. Make sure to apply a generous, even ring of putty under the flange before tightening the drain.

What if I can’t reach the drain shoe underneath the bathtub?

Access to the drain shoe often requires reaching behind the tub or through an access panel. If you lack access, you might need to cut an access hole in the wall behind the tub. Alternatively, if you’re not comfortable with this, consider consulting a plumber for the bathtub drain replacement.

So, there you have it! Hopefully, this DIY guide gives you the confidence to handle your own bathtub drain replacement. Happy plumbing!
