How to Replace a Shower Drain from Underneath

If the Shower Floor Drain replacement is on a prefabricated shower pan, you have to go at it from the bottom. This will allow you to effectively take the drain assembly apart. Be sure to turn off the electricity in the area you’ll be working in before you begin. Then, use a flat screwdriver to pop the strainer out of the drain body to expose the compression nut. Insert your compression wrench into the compression nut and turn it counterclockwise with a screwdriver to unscrew it.
Using a combination of a utility knife and drywall saw, cut a rectangular hole in the ceiling beneath the Bathroom Floor Drain. Make sure the hole is big enough to fit adjustable pliers and is along the joist so you have something to support the new drywall when patching it up. Use the adjustable pliers to loosen the drain until you can remove the rest of it with your hand. Follow that up by removing the rubber and fiber gaskets as well.
If you see that the drainpipe is welded or glued to a U-shaped pipe (also called the P-trap), you'll need to cut it. This will make it easier to push out the drain pipe and cut out the drain body. However, you'll need to know how to replace a square Floor Drain trap as well once you cut it. Without the P-trap, sewer gases can travel into your home through the drain line. In addition to the unpleasant smell, long-term exposure to this gas can be harmful.
Install a new drainpipe in the shower base and repeat the steps on how to install a shower drain on a prefabricated shower pan. Repeat the above steps for installation — from inserting the drain body, to tightening the drain nut, to snapping the Floor Drain Cover on top of the drain. However, since the shower pan is already on the floor, you don’t have to struggle with lowering and positioning it.
Assemble a new P-trap by gluing its pieces together and gluing the assembly to the drainpipe. Turn on the water and dash back downstairs to see if there are any leaks. If there are no leaks, patch up the drywall.
