Step 1: Prepare the Space

The first step is to prepare the space that the bathtub will occupy. This includes measuring the area, removing any existing fixtures, and installing the proper anchors for the bathtub walls.

Measure the Area:

Using a measuring tape, measure the area where the bathtub will be installed. Make sure to write down the measurements so that you can use them when purchasing the tub.

Remove Existing Fixtures:

Then, remove any existing fixtures that are in the space, such as a sink or shower. It’s important to make sure that all of the connections are disconnected properly before you start.

Install Anchors:

If the walls are drywall, you’ll need to install drywall anchors to ensure that they’re sturdy enough to support the weight of the bathtub. The instructions for installing the anchors will be included with the tub.

Step 2: Install the Tub

Once the space is ready, the next step is to install the tub.

Unpack the Tub:

Start by unpacking the tub and its accessories. Make sure to follow any instructions that come with the tub.

Position the Tub:

Once the tub is unpacked, position it in the space. Make sure that it’s level and secure. Use the chalk line to ensure that it’s even.

Secure the Tub:

Once the tub is in position, use the anchors to secure it to the walls. Make sure to use the pliers and Phillips head screwdriver for this step.

Install the Accessories:

Once the tub is secure, it’s time to install the accessories. These include the showerhead, faucets, and drain. Follow the instructions included with the accessories to install them properly.

Caulk and Seal:

Once the accessories are installed, it’s time to caulk and seal the tub. This will help ensure that the tub is watertight. Use the utility knife to apply the caulk and make sure to use a generous amount to ensure a tight seal.

Step 3: Test the Tub

Once the tub is installed and sealed, it’s time to test it out. Make sure to run the water for a few minutes to make sure that there are no leaks or other issues. If everything looks good, your new bathtub is ready to use!
