Installing the Freestanding Tub on a Concrete Slab

If you have decided to do it yourself, and you don’t know where to start. Follow this installation process to learn how to install a freestanding tub on a concrete slab.

Step 1: Choosing the Right Place

The first thing you need to do is to identify the best place to keep the tub. Depending on the size of your bathroom, you may decide to place it in the center beside the window.

When choosing the right place to keep the tub, the only thing you need to consider is the nearness to existing plumbing installation.

NOTE: If you are placing it far from the existing installation, you will have to do some plumbing work before starting the installation process.

Step 2: Leveling the Floor

  • Since installing the new tub on a concrete slab, it is essential to level the floor. Even though the concrete slab looks even from afar, you must not skip this step. It would help if you did not assume that an uneven concrete slab will destroy the tub.
  • To avoid any damage, you need to make the floor even by applying a coating on it. Inspect the areas that are uneven and apply the coating to them using a notched trowel.
  • If you place the tub close to the existing plumbing installation, you won’t need to create a new channel for the drain and the plumbing trap.
  • If a new bathroom is under construction or you are placing the tub far from the existing plumbing installation, you must create a channel for the drain and plumbing trap.


  1. It would help if you cleaned the floor after levelling the floor and creating the drain channel.
  2. You must also cover the drain hole, so that dirt and debris will not enter into it while levelling the floor.

Step 3: Attaching the Drain Tailpiece to The Tub

Attaching Tailpiece
  • Before placing the freestanding bathtub on the concrete slab, you need to remove the debris and dirt in the drain hole. Failure to remove the dirt and debris may cause a problem later.
  • Clean the drain hole with a clean cloth, and wait for some minutes before you pour dry silicone around and into the dry drain hole.
  • Attach and screw the drain tailpiece to the bottom side of the tub. You may decide to lubricate the rubber seal in the drain.

Step 4: Placing the Bathtub Carefully

  • After cleaning the tub drain and attaching the drain tailpiece, you can place the tub in the place you have prepared. This process requires more patience because any mistake can easily damage your bathtub.
  • Ensure that the tub corners are rightly placed. You may need to use a rubber mallet to tap it into its proper position gently.
  • Ensure that the drain tailpiece in the bottom side of the bathtub aligns with the drain hole on the concrete slab.

NOTE: You need to be very careful when placing the freestanding tub so that its weight doesn’t end up destroying the plumbing drain.

Step 5: Screwing

  • Before you start screwing, you need to ensure that the tub is in the correct position.
  • Use the drywall screws and the cordless drill to screw the tub firmly to the wall studs.
  • Go around the freestanding bathtub and repeat the same process every six inches.
  • Ensure that all the drywall screws are righty placed and tightened firmly with the wall stud.

Step 6: Installing the Overflow Components

The overflow components include the overflow rod, linkage, and plunger. You need to install all these components through the overflow drain hole.

After inserting these components inside the provided hole, you will tighten them tightly with the recommended screws.

Step 7: Testing the Tub

  • The installation process is complete, and the next thing to do is to test the tub.
  • Fill up the freestanding bathtub with water and ensure the overflow drain and the stopper are working perfectly.
  • You also need to check the screws and ensure that they are tightened correctly.
  • Now, the work is complete, and the freestanding tub is ready for use.

Note: Floor Leveling Is Very Important

  • Floor levelling is the first thing you need to do before you install your new freestanding tub. One important thing that you need to know is that you cannot start the installation process without levelling the floor.
  • The unleveled concrete slab is one of the things that can quickly destroy your new tub. So, therefore, you need to level the floor before you start the installation process.

What You Need To Do After Installation

After installing the bathtub, you also need to secure the Spray Area. The Spray Area is the area of the nearby wall and floor around the tub that receives the water splash from the tub.

It is necessary to splash, and waterproof this area, or the continuous water splash from the tub will dampen it. To avoid wall dampening, you need to make this area waterproof by applying unique sealing materials.

  • Alcohol will help to remove paint, ink, grease, and oil stains. Rub a little quantity of alcohol on these stains to remove them altogether.
  • Bleach solutions alone may not be able to remove more severe scratches and stains. You will have to use fine sandpaper to remove these scratches and stains. You can also use sandpaper to repair some damaged surfaces on your tub.
