How Do You Replace an American Standard Tub Drain?

A faulty tub drain may not seem like a big deal—until you’re ankle-deep in water that won’t drain. Whether you’re dealing with a slow leak, corrosion, or a complete clog, knowing how to replace an American Standard tub drain can save you time, money, and the headache of a service call. Fortunately, with the right tools and a bit of patience, it's a job most homeowners can handle themselves.

At Whirly Bros, we’ve helped plenty of folks tackle tub drain replacements successfully. With over two decades of plumbing know-how and hands-on experience, we're here to walk you through the process and share tips that actually work.

 

Step-by-Step: Replacing Your American Standard Tub Drain

Step 1: Gather Your Tools and Materials

Before you dive in, make sure you’ve got what you need:

• A drain removal tool or smart dumbbell wrench
• Adjustable pliers
• Silicone caulk or plumber’s putty
• A new American Standard tub drain assembly
• A clean rag and a sponge or small towel
• Screwdriver (flathead or Phillips depending on your tub)

If you're replacing a drain in one of the Walk-in tubs American Standard models, double-check the specs. Some of these drains are slightly different in design or access.

 

Step 2: Remove the Old Drain

Start by removing the drain stopper. Depending on your setup, it could twist out, pop off, or require a small set screw to be loosened. Once that’s off, use your drain wrench or smart dumbbell tool to grip and unscrew the drain flange. Turn it counterclockwise until it loosens. If it’s really stuck, apply a bit of penetrating oil and let it sit for 10 minutes.

Wipe away any old plumber’s putty or grime with a rag. The cleaner the surface, the better your new seal will be.

 

Step 3: Check the Drain Shoe

Take a look inside the drain opening. That curved pipe you see is called the drain shoe, and it connects your tub to the waste pipe. Inspect it for cracks or corrosion. If it's in bad shape, now’s the time to replace it too. If it looks solid, you’re good to go.

 

Step 4: Install the New Drain

Roll a thin bead of plumber’s putty around the underside of the new drain flange. If your kit recommends silicone instead, use that. Drop the flange into the drain hole and thread it into the drain shoe below using your wrench. Tighten it down, but don’t overdo it—just snug enough to create a watertight seal.

Wipe away any excess putty or silicone before it dries.

 

Step 5: Test It Out

Plug the drain and fill the tub with a few inches of water. Let it sit for about 10 minutes and check underneath (if accessible) for any leaks. Then release the water and watch the flow. If everything drains smoothly and there’s no water seeping below, you’ve nailed it.

This process also works on many Walk-in tubs American Standard makes, but due to their low threshold and built-in safety features, access can be tighter. Always consult your tub’s manual before disassembling anything.
