How to install a bathtub on concrete floor?

Installing a bathtub is not as difficult as it may seem. It’s all about following a few basic steps and employing some common sense. The first step is to make sure you have a level, solid foundation on which to place the tub. In this article, we’ll show you how to properly install your bathtub on concrete floor so that it looks great and lasts for years!

Steps of Installing a Bathtub on Concrete Floor

Follow the steps below to install a bathtub on concrete floor:

Step 1: Roughing in Plumbing Lines and Drain

Use a hammer and chisel to rough in the plumbing lines. Then, use a stud finder to locate the studs behind where you’ll be installing your tub. Test-fit all of your pipes to ensure they can fit through the hole before drilling into them.

Drill a hole for the drain using a spade bit set at 1-1/2 inches deep and 7 inches in diameter (to make sure there’s plenty of room for water). Attach the toilet flange to floor with screws or nails by following instructions provided with your particular type of fixture. Attach it securely so that no water leaks out during installation later on!

Install drain pipe using an adjustable wrench, then tighten nuts onto both ends with pliers if necessary until secure enough not rock back & forth when moved slightly side-to-side without popping off completely like those cheap plastic ones do sometimes unfortunately; this way there won’t be any issues later down road after everything else has been done correctly first time around which makes sense because nothing good happens second guessing yourself all day long either way though so just keep doing what feels right knowing that everything will turn out fine eventually.

Step 2: Install the (Optional) Shower Surround

Once the tub has been set in place and leveled, you can install the shower surround. This is an optional step, but if you want to use your bathroom for more than just bathing, it will make sense to add a shower surround at this point. Make sure that the surround is level and plumb before proceeding with fastening it into place.

Step 3: Prepare the Wall Surround and Deck Area

The next step is to prepare the wall surround and deck area. To do this, you will need to remove any drywall or tile that was previously installed. You will also want to remove any existing tub surround, as well as any wall-mounted toilets and mirrors.

Step 4: Set the Tub and Make the Connections

Now that you’ve placed your tub in place, it’s time to make the connections. First, connect the water lines by connecting one end of each pipe to its corresponding part on the tub. Then, connect the drain and overflow by attaching them to their respective parts on both sides of the tub.

Step 5: Finish the Trim Around the Tub and Complete the Installation

You are almost finished with your new tub installation. The final step is to trim around the tub and complete the installation by installing the shower head and faucet. Now that you have installed a bathtub on concrete floor, it’s time to clean up!


Installing a new bathtub is not a project that should be taken lightly. It’s important to follow all safety precautions and use the proper tools and materials when working with concrete and tile.
