Tools You’ll Need

Yes, you’ll require a set of tools for the job. Let’s take a look at them:

Method 1: How to Level an Existing Bathtub With Mortar Process?

Even though you’ll need the help of a friend to complete this method, it’s not time-consuming. Let’s look at the whole step-step process:

Step 1: Measure the Distance & Dimension

Firstly, take your measuring tape. Then, start measuring the distance between the side flanges and the base of the tub. Also, measure the length of the legs of the tube.

Here, you’ll need to know that the legs would be normally hidden under the mortar. So, if you don’t have a decorative leg in your tub, it’ll still work.

On the other hand, you need to measure the dimension of the tub as well. Also, make sure you trace the outline where you’ll install the tub again.

Step 2: Mix the Mortar

After you’re done, start mixing a thin-set mortar. Use water to mix the mortar and keep it as it is for a few minutes. By doing this, you’ll allow the mortar to thicken.

Following this, take a trowel and start spreading the mortar on the marked area. You shouldn’t stop here as you’ll need to add the mortar till it reaches an inch deep.

Step 3: Place Tub on Mortar

Take the tub and put it on the top. Here, you’ll need a friend to help you out with the process. After you’re done placing the tub on the top, push it downwards. You’ll need to push it till the flange touches the floor.

Step 4: Repeat the Process

Yes, you heard me right. You’ll need to continue the process for the remaining three sides of the tub. Push the sides down so that the tub is in a leveled position.

In the end, make sure the whole tub is leveled. If needed, take your measuring tape out and check the measurements.

Step 5: Clean & Dry the Mortar

You’ll need to wipe away any bit of mortar that is under the tub. Take a trowel and start taking off any residue. However, you’ll have to make sure that you’re doing this before the mortar dries off.

Because if you don’t, the mortar will dry after a while. As a result, your work will become even harder. Also, make sure you’re cleaning the floor as well.

Turns out, the mortar can take even 24-30hours to dry completely. So, don’t be impatient and let the drying process complete before using the tub again.

Method 2: How to Level an Existing Bathtub With Metal Shims Process?

Using shims to raise the level of the bathtub is an efficient way of solving the problem. However, you can also use wooden shims or hardwood as an alternative. So, let’s look at the step-step process:

Step 1: Add Shims

Firstly, you’ll need someone to lift the tub. After this, you’ll have to place shims under the tub or the base. Mainly, target the legs of the tub or the base.

Here, you can use hardwood, softwood, wooden shims, and metal bathtub shims to cover up the level. The shims can compress the weight of the water and bathers over time.

Step 2: Repeat the Process

You’ll have to continue the process on the remaining sides. So, lift the tub up and start adding shims in the tub as necessary. Make sure you are maintaining a level as well.

Step 3: Test the Level & Put Caulk

Measure and test each of the sides to confirm that the tub is leveled. After you’re done, lift the tub again. And this time apply silicone caulk to secure shims in place.

Following this, take the utility knife and start cutting the caulk. After this, squeeze the bottom. As a result, excess caulk will start coming out of the bottom of the shim.

Step 4: Repeat the Process

With the rest of the shims, do the same. First, lift up the tub and start adding caulk under the shims to secure it. Also, if you find that the level is not right, start again.

However, make sure you’re doing all this process before the caulk dries up. Because it’ll make the process hard if it dries.

Step 5: Clean & Dry

Similarly, with the previous method, clean the floor. Also, take out any residue from the tub. Keep in mind that you’ll have to do this before the caulk dries up in place.

If the caulk dries up in place, you’ll have to scrape it all off. And yes, you’ll need to give it time for the drying process to complete. 24-26hours is enough so you can use the tub again after drying it for this time.
