How To Install And Replace A New Bathtub Drain

Any soothing bath requires a bathtub drain that runs smoothly. But, these drains can rust or clog with time, making it difficult to take a bath and leading to water buildup in your tub. It may be time to replace or install your bathtub drain if you’re having problems with it. This thorough tutorial will walk you through every step of the procedure so you can once again enjoy a bath without clogs.

Understanding Your Bathtub Drain

It is important to understand the different kinds of bathtub drains that are offered before beginning the installation or replacement method. The two most common kinds are:

Toe-Tap Drains: These kinds of drains are commonly seen in modern bathtubs and are operated by a push-and-pull mechanism.

Trip Lever Drain: The overflow plate of the bathtub has a lever that controls these drains.

Start by determining the type of drain in your bathtub, as this will specify the particular procedure that needs to be followed for installation or repair.


Tools and Materials You’ll Need

Get the required tools and materials before starting the procedure. To help you get started, check the following list:


  • Screw Driver
  • Pliers
  • Pipe Wrench
  • Hacksaw
  • Plunger
  • Plumber’s Putty


  • New Drain
  • Drain Gasket 
  • Silicon Caulk
  • Teflon Tape
  • Bucket 
  • Towels

Safety Measures

Your primary focus should always be safety. Before you begin, remember the following measures:

  1. To prevent inhaling chemical vapors from any chemicals you may use during the process, make sure your bathroom has enough ventilation.
  1. Wear protective gloves and goggles whenever using power tools to safeguard your hands and eyes.
  1. When using acidic substances such as drain cleaners, carefully read the directions and follow them.

Replacing a Bathtub Drain

Use these steps if you’re replacing an existing drain:

  • Find the Drain: Look for the drain access panel in your bathtub. Usually, it’s in a wall behind the tub or under it.
  • Disconnect the Drain: To remove the nuts or screws holding the drain cover in place, use pliers or a screwdriver. You will be able to access the drain components once it is removed.
  • Remove the Old Drain: Carefully loosen and remove the old drain from the tub using a pipe wrench. Be careful; you may need to use some force.
  • Clean the Area: Give the area surrounding the former drain hole a good cleaning. Eliminate any remaining material or old putty.
  • Installing the New Drain: Fill the drain hole with the plumber’s putty on the underside of the new drain flange. Securely tighten it using a pipe wrench.
  • Attach the Drain Gasket: Cover the flange with a drain gasket and tighten its fittings.
  • Reattach the Drain Cover: Screws or nuts should be used to firmly reattach the drain cover.
  • Test the Drain: To make sure the new drain is correctly sealed and working, run water into the bathtub.

Installing a Bathtub Drain

Installing a drain in a newly installed bathtub needs slightly different steps:

  • Prepare the Tub: Before installing the drain, verify the tub is correctly in place and level.
  • Place the Drain: Slide the drain flange into the bathtub’s drain opening.
  • Apply Plumber’s Putty: To form a watertight seal, liberally apply the plumber’s putty to the underside of the flange.
  • Fasten the Drain Gasket: Cover the flange with a drain gasket and fasten it tightly.
  • Tighten the Locknut:  To tighten the Locknut, thread it onto the drain tailpiece and use a pipe wrench to tighten it.
  • Attach the Overflow Plate:  Screws are used to firmly fasten the overflow plate in place.
  • Install the Trip Lever: Attach the trip lever mechanism to the overflow plate if your tub has a trip lever drain.
  • Test the Drain: To make sure the drain is correctly sealed and operating, run water into the bathtub.

Troubleshooting Common Issues

A plunger or drain snake can be used to remove hair and debris from a slow-draining bathtub, which is one of the most typical solutions to bathtub drain problems. When dealing with a leaky drain, make sure that silicone caulk or plumber’s putty has been applied correctly. If required, take the drain apart and reseal it. If you have clogs, think about using a drain cleaner or vinegar and baking soda mixture to clear the obstruction. Regular maintenance can avoid these problems altogether and guarantee a leak-free, smoothly operating bathtub drain. Examples of this maintenance include cleaning the overflow plate and drain cover and using a strainer to collect debris.

Maintenance Tips

Your bathtub drain can last longer with proper care. Here are some tips:

  • To avoid soap scum and debris accumulation, clean the overflow plate and drain cover on a regular basis.
  • Strong chemicals should not be poured down the drain since they can corrode the parts and cause leaks.
  • To lower the chance of clogs, use a drain strainer to capture hair and other debris before it enters the drain.


For every homeowner, knowing how to install or replace a bathtub drain is an invaluable skill. In addition to guaranteeing that you may take a soothing bath without worrying about a clogged or leaky drain, it can help you save money on plumbing services.
