How to Install a Bathroom Vanity with Plumbing in the Floor

Installing a bathroom vanity with plumbing in the floor can seem like a daunting task, but it is actually a fairly straightforward process. By following these step-by-step instructions, you can have your new vanity installed and functioning in no time.

Step 1: Gather Your Tools and Materials

Before you begin, you will need to gather the following tools and materials:

Bathroom vanity
Faucet
Drain assembly
P-trap
Supply lines
Floor flange
Screwdriver
Wrench
Plumber's putty
Level

Step 2: Prepare the Floor

The first step is to prepare the floor for the vanity. This involves removing any existing flooring or fixtures that may be in the way. If the floor is not level, you may need to level it using a self-leveling compound.

Step 3: Install the Floor Flange

Once the floor is prepared, you need to install the floor flange. The floor flange is a metal ring that fits around the drain hole in the floor. It provides a secure connection for the drain assembly.

To install the floor flange, simply apply a bead of plumber's putty around the base of the flange and then press it into place over the drain hole. Make sure the flange is level and secure.

Step 4: Install the Drain Assembly

The next step is to install the drain assembly. The drain assembly consists of a drain pipe, a P-trap, and a tailpiece. The drain pipe fits into the floor flange, the P-trap connects to the drain pipe, and the tailpiece connects to the sink drain.

To install the drain assembly, simply insert the drain pipe into the floor flange and secure it with a lock nut. Then, connect the P-trap to the drain pipe and the tailpiece to the sink drain. Make sure all of the connections are tight.

Step 5: Install the Supply Lines

The next step is to install the supply lines. The supply lines are the pipes that connect the faucet to the water supply. They are typically made of copper or PEX.

To install the supply lines, simply connect one end of each line to the faucet and the other end to the water supply. Make sure the connections are tight and that the supply lines are not kinked or twisted.

Step 6: Install the Vanity

Now it is time to install the vanity. To do this, simply lift the vanity into place and align it with the floor flange and the supply lines. Once the vanity is in place, secure it to the wall using screws or bolts.

Step 7: Connect the Plumbing

Now you need to connect the plumbing. To do this, simply connect the drain assembly to the drain pipe and the supply lines to the faucet. Make sure all of the connections are tight and that there are no leaks.

Step 8: Finish Up

Once the plumbing is connected, you can finish up the installation. This involves installing the faucet and the sink. To install the faucet, simply insert it into the faucet holes and secure it with a lock nut. To install the sink, simply place it on top of the vanity and secure it with silicone sealant.

Congratulations! You have now successfully installed your bathroom vanity with plumbing in the floor.
