In this article, we will walk you through the steps of how to replace a bathtub, from understanding the basics to finalizing the installation.

Before you begin the process of replacing your bathtub, it’s important to understand the basics of what you’re working with. This includes knowing the size and type of your current bathtub, as well as the type of material it’s made from. You’ll also need to decide on the type of bathtub you want to replace it with, whether it’s a standard alcove bathtub, a freestanding tub, or a soaking tub.

Key Takeaways

  • Replacing a bathtub can be a DIY project with the right tools and knowledge.
  • Understanding the basics of your current bathtub and the type of replacement bathtub you want is important before starting the process.
  • Gathering the necessary tools and materials is crucial for a successful bathtub replacement.

Understanding the Basics

Replacing a bathtub can be a daunting task, but with the right tools and knowledge, it can be a DIY project that can save you a lot of money. Before you begin, it is important to understand the basics of bathtub replacement.

Firstly, you need to decide whether you want to remove the old bathtub yourself or hire a professional to do it. Removing a bathtub involves disconnecting the plumbing, breaking the seal around the tub, and lifting it out of the bathroom. If you are not experienced with plumbing or demolition work, it is recommended that you hire a professional to do this part of the job.

Once the old bathtub has been removed, you can begin installing the new one. Before you purchase a new bathtub, it is important to measure the space where the old one was located to ensure that the new one will fit. Most standard bathtubs are 5-feet long and either 30- or 32-inches wide, but there are many different sizes and styles available.

When installing the new bathtub, you will need to ensure that it is level and secure. This involves using a level to check that the bathtub is not sloping in any direction and using shims to adjust the height if necessary. You will also need to secure the bathtub to the wall studs using screws or brackets.

It is important to note that replacing a bathtub may require permits from your local building department. Before beginning any bathroom remodel, it is recommended that you check with your local building department to ensure that you have all the necessary permits.

If you are unsure about any part of the bathtub replacement process, it is always best to consult with a professional. The Home Depot offers bathtub replacement services that can help you with every step of the process, from selecting the right bathtub to installing it in your bathroom.

Choosing the Right Bathtub

When it comes to replacing a bathtub, choosing the right one can make all the difference. With so many options available, it can be overwhelming to decide which bathtub is right for you. In this section, we’ll go over some key factors to consider when choosing a new bathtub.

Size and Style

First and foremost, you’ll want to choose a bathtub that fits your bathroom’s size and style. Measure your current bathtub alcove around the shower walls to determine the right size tub for your space. Keep in mind that most standard bathtubs are 5-feet long and either 30- or 32-inches wide. Additionally, consider the style of your bathroom and choose a bathtub that complements the overall aesthetic.

Materials

When it comes to materials, there are a variety of options to choose from. Acrylic and fiberglass tubs are lightweight, durable, and affordable options. Enameled steel and cast iron tubs are heavier and more expensive, but offer a classic and luxurious look. Additionally, consider the comfort of the tub and choose a material that retains heat well, such as acrylic or cast iron.

Drain Placement

Another important factor to consider is the drain placement of the bathtub. Choose a left or right drain tub based on the location of your current drain. This will save you time and money during installation.

Budget

Of course, budget is an important consideration when choosing a new bathtub. Standard bathtubs can be purchased at your local home center and installed by a plumbing professional. However, if you’re looking for a more luxurious option, consider a spa tub or a tub with additional features.

In summary, when choosing a new bathtub, consider the size and style, materials, drain placement, and budget. By taking these factors into account, you can ensure that you choose the right bathtub for your needs and preferences.

Preparation Before Bathtub Removal

Before beginning the process of replacing a bathtub, it is important to take the necessary steps to prepare the area. This includes shutting off the water supply and disconnecting the drain.

First, turn off the water supply to the bathtub. This can typically be done by turning off the valve located near the bathtub or by shutting off the main water supply to the house. It is important to make sure the water is completely turned off before proceeding.

Next, disconnect the drain. This can be done by removing the drain cover and unscrewing the drain flange. Make sure to have a bucket or towel handy to catch any water that may be left in the drain pipes.

It is also important to remove any fixtures or accessories attached to the bathtub, such as the bathtub faucet or stem. This can typically be done by unscrewing the fixtures using a wrench or pliers.

Before removing the bathtub, it is important to inspect the area surrounding the bathtub. Check for any damage to the studs, underlayment, or baseboard. Make sure the area is level and free of any debris.

If the bathtub is surrounded by a tub surround, inspect the flange to make sure it is securely fastened to the studs. If the tub surround is made of fiberglass or acrylic, be careful not to damage it during the removal process.

Finally, make sure there is an access panel to the bathtub’s plumbing. This will make it easier to access the plumbing in case of any future repairs or replacements.

By taking the time to properly prepare the area before removing the bathtub, the process will be smoother and less likely to cause damage to the surrounding area.

Removing the Old Bathtub

Replacing an old bathtub can be a great way to update your bathroom and increase the value of your home. Before you can install a new bathtub, however, you need to remove the old one. Here’s how to do it:

Step 1: Turn off the Water Supply

Before you start removing the old bathtub, make sure you turn off the water supply. You can usually do this by turning the shut-off valves located near the bathtub. If you can’t find the shut-off valves, turn off the main water supply to your home.

Step 2: Drain Removal

The next step is to remove the drain. You can do this by using a drain removal tool or a pair of pliers. Simply unscrew the drain and lift it out of the bathtub.

Step 3: Bathtub Removal

Once the drain is removed, you can start removing the bathtub. Start by removing any screws or nails that are holding the bathtub in place. You may need to use a screwdriver or reciprocating saw to do this.

Next, use a pry bar to loosen the bathtub from the wall. Be careful not to damage the wall or the plumbing behind it. If the bathtub is glued to the wall, you may need to use a sledgehammer to break it free.

Step 4: Clean Up

After you’ve removed the bathtub, clean up any debris and remove any remaining screws or nails from the area. You’re now ready to install your new bathtub.

By following these steps, you can remove your old bathtub and get ready for a new one. Just be sure to take your time and be careful not to damage any surrounding areas.

Installation of New Bathtub

Once you have removed your old bathtub, it’s time to install the new one. Here are the steps to follow:

  1. Level the Tub: Place the new tub in the alcove and use a level to ensure that it’s level and plumb. If it’s not level, use shims to adjust it until it is.

  2. Attach the Tub to the Studs: Use screws to attach the ledger board to the studs. Then, attach the tub flange to the ledger board using screws. Make sure that the tub is securely attached to the studs.

  3. Install the Overflow Drain and Drain Flange: Apply ABS glue to the overflow drain and drain flange. Then, insert them into the appropriate holes in the tub. Use a rubber gasket to seal the connections.

  4. Install the Tub Surround: If you’re installing a tub surround, now is the time to do it. Follow the manufacturer’s instructions to attach the surround to the studs.

  5. Test for Leaks: Once you’ve installed the new tub, fill it with water and let it sit for a few hours. Check for any leaks around the drain and overflow areas. If you find any leaks, fix them before using the tub.

Remember to follow the manufacturer’s instructions for installing your specific type of tub. If you’re installing an acrylic or fiberglass tub, be careful not to damage it during installation. With these steps, you can install your new bathtub with confidence and enjoy a relaxing soak in your new tub.

Finalizing the Installation

Once you have successfully installed your new bathtub, it’s time to finalize the installation. This involves several important steps to ensure that your bathtub is properly secured and sealed.

Caulking

The first step in finalizing the installation is to apply caulk around the edges of the bathtub. This will help to seal the gap between the tub and the wall, preventing water from seeping in. Use a high-quality caulk that is specifically designed for use in bathrooms. Apply the caulk in a continuous bead around the edges of the tub, using a caulk gun. Smooth out the caulk with a caulk smoothing tool or your finger, making sure to fill any gaps or voids.

Plumbing

Next, you will need to connect the plumbing. This involves attaching the water supply lines, drain assembly, and any other plumbing fixtures, such as the bathtub faucet or tub spout. Make sure to use the appropriate fittings and connectors for your plumbing system. Tighten all connections securely, but be careful not to over-tighten, as this can cause damage to the plumbing.

Test for Leaks

Before you can start using your new bathtub, you will need to test for leaks. Fill the tub with water and let it sit for several hours. Check the area around the tub for any signs of water leakage. If you notice any leaks, you will need to identify and fix the problem before using the bathtub.

Tub Surround

If you are installing a tub surround, now is the time to attach it to the wall. Follow the manufacturer’s instructions carefully, making sure to use the appropriate adhesive and fasteners. Once the tub surround is in place, seal the edges with caulk to prevent water from seeping in.

P-Trap

Finally, you will need to install the P-trap. This is a U-shaped pipe that connects the drain assembly to the plumbing system. Make sure that the P-trap is properly aligned and tightened, and that there are no leaks.

By following these steps, you can ensure that your new bathtub is properly installed and ready for use. Remember to follow all safety guidelines and obtain any necessary permits before starting your installation.

Post Installation Checks and Maintenance

After installing the new bathtub, it is important to perform a few post-installation checks to ensure everything is working correctly. Here are some things to check:

Water Supply and Drain

Check the water supply and drain connections to make sure they are tight and secure. Turn on the water and check for any leaks. If you notice any leaks, tighten the connections until the leak stops.

Plumbing

Check the plumbing connections to make sure they are tight and secure. If you notice any leaks, tighten the connections until the leak stops. Also, check the P-trap to make sure it is properly installed and not leaking.

Level

Check the level of the bathtub to make sure it is even. Use a level to check the sides and front of the bathtub. If the bathtub is not level, adjust the feet until it is level.

Overflow Drain

Check the overflow drain to make sure it is properly installed and not leaking. Fill the bathtub with water and let it drain to check for leaks.

Drain Flange

Check the drain flange to make sure it is properly installed and not leaking. Fill the bathtub with water and let it drain to check for leaks.

Test for Leaks

After checking all the connections and drains, fill the bathtub with water and let it sit for a few minutes. Check for any leaks around the bathtub and plumbing connections. If you notice any leaks, tighten the connections until the leak stops.

Performing these post-installation checks will ensure your new bathtub is functioning correctly and prevent any future issues. Remember to perform regular maintenance on your bathtub to keep it in good condition. Clean the bathtub regularly with a non-abrasive cleaner and avoid using harsh chemicals that can damage the surface.
