If you’ve ever wondered how to install a bathtub, you’re not alone. Millions of DIY enthusiasts have experienced the urge and drive to replace an old and ugly tub with a brand-new model.

Bathtub installation costs can be intimidating and completing an at-home installation can save you money and help you learn a new home improvement skill. Installing a new bathtub isn’t as challenging as it initially seems, especially if you’re prepared.

1. Gather Your Supplies

Before you can install a new tub, you’ll need to acquire one. This can be one of the most exciting stages of the installation process.

You could choose to go with another standard bathtub, or you could get creative with your replacement. After all, a walk-in bathtub can be quite an attractive and unique luxury.

You’ll also need caulk, a hammer or electric screwdriver, and a leveler. You may require a few additional project-specific supplies such as shims, nails, pliers, plumbing putty, and wall panels.

2. Remove Debris and Dry-Fit

Before you can begin installing a new bathtub, you need to remove any remnants of the last one. Be sure to clean and prepare the area where your new bathtub will go. Squeeze it into its intended space to check the fit.

3. Attach Your Drains

You’ll want to secure your drain flange piece first. Simply push it down into the drain and adhere it to the body of the tub with a drain shoe. Attach the cover plate and connect the overflow pipe and drain pipe.

Finally, you can secure the drain strainer at the top of the drain flange. Once you’ve tightened these components and double-checked them, you’re ready to grab some caulk and get to work.

4. Secure the Bathtub

Once your bathtub is securely attached to the drain lines, you have a little fun with your caulking and drywalling. This stage is all about securing the bathtub to the room. You’ll want to use a series of tub flanges to attach the tub to its nearest walls.

You’ll also want to seal major cracks with plenty of well-poured caulking. If you’re interested in installing a baseboard around the bottom of your bathtub, now would be an excellent time to go ahead and get that done.

5. Connect the Water Lines

When your bathtub has been secured and cuddled into its place via baseboards and paneling, it’s time to connect the water lines. You could choose this moment to turn the water back on.

But if your bathroom has an appliance-specific water line, you could also choose to wait a little while. While your caulk is hardening, you can double-check your drain and pipe connections.

6. Double-Check Your Connections

Always double check your connections before making any final caulking decisions. Doing so can help you prevent frustration and tedious de-caulking and re-caulking in the immediate future.

Check your drains to ensure that they are tightly and securely connected. When you’re certain that they are, you may be tempted to open your nearest access panel and get the water flowing to your new bathtub.

You could do this, but it may be better to wait.

7. Seal and Wait

Apply any last-minute seals you might need and wipe away excess caulking before it settles and hardens. Be sure to wait a minimum of 24 hours before attempting to use, move, or interact with your new bathtub.

Now You Know How to Install a Bathtub

Congratulations! You are now ready to get started on your DIY bathtub installation project. All you need to do is gather your supplies, remove any remaining debris, and fit your tub into its designated spot.

Of course, you’ll also need to attach the drains, secure the bathtub to the floor and walls, and connect the water lines. And you may want to double-check your connections and seals before moseying along.
