Shared to:

Replacing a bathtub drain may sound like an overwhelming task, but it’s actually a manageable DIY project that can save you money and restore your bathroom’s functionality. Whether you’re dealing with a clogged drain, water leaks, or just updating your old hardware for a fresh look, replacing the drain yourself is a great way to improve your bath’s performance without hiring a plumber.

In this blog, we will guide you through the process of replacing a bathtub drain, from gathering the right tools to completing the installation. By the end, you’ll have the confidence to tackle the job with ease.

Before You Begin: What You Need

To start, make sure you have the right tools for the job. Here’s a list of everything you’ll need:

  • Replacement drain assembly (make sure it matches the size and type of your existing drain)
  • Pipe wrench or plumbing pliers
  • Flathead screwdriver
  • Plumber’s putty
  • Drain removal tool (optional, but helpful)
  • Bucket or towel to catch any water
  • Caulking gun (if needed for sealing)

Having these tools ready will make your task much smoother. Don’t forget to turn off the water supply and remove any standing water from your bathtub before getting started.

Step 1: Remove the Old Bathtub Drain

The first step in replacing the bathtub drain is removing the old one. Start by inspecting the drain cover or stopper to see if it’s screwed in or has a pop-up mechanism. For a basic drain cover, use a flathead screwdriver to remove the screws. Once the cover is removed, check the drain flange (the part that connects to the bathtub) for any remaining screws or fasteners.

If you’re dealing with a pop-up drain, you might need to detach the stopper mechanism. This usually involves unscrewing the linkage underneath the tub. Once it’s disconnected, you can move on to the main drain assembly.

Next, use your pipe wrench or plumbing pliers to unscrew the drain flange from the drainpipe. If it’s stuck, applying some penetrating oil can help loosen it. In cases where the flange is rusted or extremely tight, a specialized drain removal tool can make the job easier. Remove all components carefully, and be prepared for some water to spill out, so have your bucket or towel ready.

Step 2: Clean the Area and Prepare for the New Drain

Before installing the new drain, you’ll want to clean the area around the drain opening. Scrape away any old plumber’s putty or debris that might be left behind. This step ensures that your new drain will fit snugly and prevent leaks later.

Inspect the drainpipe to make sure there’s no damage. If the pipe is cracked or corroded, now would be a good time to replace or repair it. You may also want to check for any buildup or clogs further down the pipe to ensure the drain will flow properly once it’s in place.

Step 3: Install the New Bathtub Drain

Now comes the exciting part—installing the new drain! First, take the new drain assembly and apply a small amount of plumber’s putty around the edge of the drain flange. This creates a seal that prevents leaks. Press the flange gently into the drain opening to secure it in place.

Once the flange is properly seated, screw the drain tailpiece (the long, pipe-like part) into the drain assembly, making sure it’s tightly connected. If your new drain has a stopper mechanism, reattach it by screwing the linkage or pop-up mechanism into place. Be sure to follow the instructions that come with the new drain, as there may be slight variations depending on the model.

Step 4: Test for Leaks

After everything is installed, it’s time to test your work. Run some water into the tub and check for leaks around the drain flange and connections. If you notice any water seeping out, turn off the water and tighten the drain assembly or add more plumber’s putty to the flange. Once the leak is fixed, test the stopper to make sure it’s functioning correctly.

Step 5: Finishing Touches

Now that your new drain is secure and leak-free, you’re done! If you want to give the area a finished look, you can apply a bead of caulk around the edge of the drain flange to create a clean, polished appearance. This step is optional, but it can help seal the edges and give your bathtub a sleek, professional look.

Why Should You Replace Your Bathtub Drain?

There are a few reasons why you might consider replacing your bathtub drain. Some of the most common issues include:

  1. Leaking or Water Damage: Over time, the rubber seals or connections in the drain can wear out, leading to leaks. A leaky drain can cause water damage to your bathroom flooring or walls, which can be costly to repair.
  2. Slow Draining: If you’ve tried every trick to clear a clogged drain and it still drains slowly, it might be time for a new drain. Old, corroded drains can get clogged with mineral deposits and hair, making it difficult for water to flow freely.
  3. Aesthetic Upgrade: If your old drain is looking rusty or outdated, replacing it with a new, modern design can give your bathroom an instant facelift.
