Tools and Materials
The following tools and materials are required to install a bathtub on a concrete slab:
- Concrete slab
- Bathtub
- Plumbing supplies
- Measuring tape
- Level
- Saw
- Drill
- Screwdriver
- Tape measure
- Combination square
- Caulk gun
- Grout
- Sponge
- Cloth

Preparation
Before you begin installing the bathtub, there are a few things you need to do to prepare the concrete slab.
First, you need to measure the dimensions of the bathtub and the concrete slab. The bathtub should be slightly smaller than the concrete slab so that there is a gap around the perimeter of the bathtub. This gap will allow water to drain away from the bathtub and prevent it from pooling underneath.
Once you have measured the dimensions of the bathtub and the concrete slab, you need to mark the location of the bathtub on the concrete slab. Use a pencil or marker to draw a line around the perimeter of the bathtub.
Next, you need to cut the plywood to the dimensions of the bathtub. The plywood will serve as a subfloor for the bathtub and will help to distribute the weight of the bathtub evenly across the concrete slab.
To cut the plywood, you can use a circular saw or a hand saw. Make sure that the plywood is cut to the exact dimensions of the bathtub so that it fits snugly against the concrete slab.
Once you have cut the plywood, you need to place it on the concrete slab. Make sure that the plywood is centered on the mark that you made earlier.
Next, you need to level the plywood. Use a level to check that the plywood is level in both directions. If the plywood is not level, you can use shims to level it.

Installation
Now that the plywood is in place, you can begin installing the bathtub.
First, you need to connect the bathtub to the plumbing. The bathtub will need to be connected to the hot and cold water supply lines, as well as the drain line.
To connect the bathtub to the plumbing, you will need to use a combination of PEX tubing, copper tubing, and PVC pipe. Make sure that all of the connections are tight and secure.
Once the bathtub is connected to the plumbing, you can begin installing it on the plywood subfloor.
To install the bathtub, you will need to use a level to make sure that the bathtub is level in both directions. If the bathtub is not level, you can use shims to level it.
Once the bathtub is level, you can begin attaching it to the plywood subfloor. You can use screws or nails to attach the bathtub to the plywood.
Make sure that the screws or nails are long enough to go through the plywood and into the concrete slab.
Once the bathtub is attached to the plywood subfloor, you can begin grouting the bathtub.
To grout the bathtub, you will need to mix grout according to the manufacturer’s instructions. Then, you will need to apply the grout to the joints between the bathtub and the plywood subfloor.
Use a grout float to spread the grout evenly and to remove any air bubbles.
Once the grout has dried, you can clean the bathtub with a sponge and cloth.

3. Installation
To install a bathtub on a concrete slab, you will need the following materials:
- A bathtub
- A plywood subfloor
- A bathtub drain
- A bathtub faucet
- A bathtub overflow drain
- Silicone caulk
- Grout
- A saw
- A drill
- A screwdriver
- A measuring tape
- A level
Step 1: Prepare the concrete slab
The first step is to prepare the concrete slab for the bathtub. This involves making sure that the slab is level and smooth. If the slab is not level, you will need to use a level to find the high spots and low spots. Once you have found the high spots and low spots, you can use a saw to cut away the high spots and a hammer and chisel to level the low spots.
Once the slab is level, you will need to smooth it out. You can do this by using a concrete resurfacer or a self-leveling compound.
Step 2: Install the plywood subfloor
The next step is to install the plywood subfloor. The plywood subfloor will provide a level surface for the bathtub to sit on.
To install the plywood subfloor, you will need to cut the plywood to the correct size. Once the plywood is cut, you will need to attach it to the concrete slab using screws.
Step 3: Install the bathtub drain
The next step is to install the bathtub drain. The bathtub drain will allow water to drain out of the bathtub.
To install the bathtub drain, you will need to cut a hole in the plywood subfloor. The hole should be large enough to fit the bathtub drain. Once the hole is cut, you will need to install the bathtub drain using screws.
Step 4: Install the bathtub faucet
The next step is to install the bathtub faucet. The bathtub faucet will allow you to turn on and off the water to the bathtub.
To install the bathtub faucet, you will need to cut a hole in the wall behind the bathtub. The hole should be large enough to fit the bathtub faucet. Once the hole is cut, you will need to install the bathtub faucet using screws.
Step 5: Install the bathtub overflow drain
The next step is to install the bathtub overflow drain. The bathtub overflow drain will allow water to drain out of the bathtub if it overflows.
To install the bathtub overflow drain, you will need to cut a hole in the wall behind the bathtub. The hole should be large enough to fit the bathtub overflow drain. Once the hole is cut, you will need to install the bathtub overflow drain using screws.
Step 6: Caulk around the bathtub
The next step is to caulk around the bathtub. The caulk will seal the bathtub to the plywood subfloor and prevent water from leaking.
To caulk around the bathtub, you will need to apply a bead of silicone caulk around the bathtub. Once the caulk is applied, you will need to smooth it out with your finger.
Step 7: Grout the bathtub
The final step is to grout the bathtub. The grout will seal the joints between the tiles and prevent water from leaking.
To grout the bathtub, you will need to mix grout according to the package directions. Once the grout is mixed, you will need to apply it to the joints between the tiles. Once the grout is applied, you will need to use a grout float to smooth it out.
4. Finishing Touches
Once the bathtub is installed, you will need to do a few finishing touches.
- Wipe down the bathtub with a sponge and cloth.
- Enjoy your new bathtub!
