There are a few different ways to seal a bathtub drain, but the most common method is to use a plumber’s putty. Plumber’s putty is a pliable, water-resistant sealant that can be used to seal around the drain flange.

To seal a bathtub drain with plumber’s putty, follow these steps:

1. Clean the area around the drain with a damp cloth.
2. Apply a thin layer of plumber’s putty around the drain flange.
3. Press the putty into the gap between the drain and the bathtub.
4. Allow the putty to dry completely.

Once the putty has dried, you can test the drain to make sure it’s sealed properly. Run some water in the bathtub and make sure that no water leaks out around the drain.

To use a drain plug or stopper, simply insert it into the drain and turn it clockwise until it’s snug. You may need to use a wrench or pliers to tighten the drain plug or stopper.

Once the drain plug or stopper is in place, you can test the drain to make sure it’s sealed properly. Run some water in the bathtub and make sure that no water leaks out around the drain.

3. Press the plumber’s putty around the drain flange.
4. Smooth out the plumber’s putty with your fingers.

Once you’ve applied the plumber’s putty, you can press the drain cover back into place.
