How to Install Bathroom Double Sink Plumbing

Installing a double sink in your bathroom can be a great way to upgrade your space and make it more functional. While it may seem like a daunting task, it's actually quite doable with a little planning and preparation. Here's a step-by-step guide to help you through the process:

Step 1: Gather Your Materials

Before you begin, you'll need to gather all the necessary materials. This includes:

Two sinks
Two faucets
Two P-traps
Two drain lines
Two supply lines
Two shut-off valves
Plumber's putty
Teflon tape
Basin wrench
Adjustable wrench

Step 2: Prepare the Sink Basin

Once you have all your materials, you can begin preparing the sink basin. This involves removing the old sink and cleaning the countertop. If you're installing the sink in a new vanity, you'll need to cut out the hole for the sink.

Step 3: Install the Faucets

The next step is to install the faucets. Start by wrapping the threads of the faucet with Teflon tape. Then, insert the faucet into the hole in the sink and tighten it down with a basin wrench.

Step 4: Install the P-Traps

The P-traps are the curved pipes that connect the sink drains to the drain line. To install the P-traps, first apply a bead of plumber's putty to the end of the trap arm. Then, insert the trap arm into the drain hole in the sink and tighten it down with an adjustable wrench.

Step 5: Install the Drain Lines

The drain lines are the pipes that carry the water from the sink drains to the main drain line. To install the drain lines, first cut the pipes to the desired length. Then, insert the pipes into the P-traps and tighten them down with an adjustable wrench.

Step 6: Install the Supply Lines

The supply lines are the pipes that carry the hot and cold water to the faucets. To install the supply lines, first cut the pipes to the desired length. Then, insert the pipes into the shut-off valves and tighten them down with an adjustable wrench.

Step 7: Connect the Supply Lines to the Faucets

Now it's time to connect the supply lines to the faucets. Start by wrapping the threads of the supply lines with Teflon tape. Then, insert the supply lines into the faucets and tighten them down with an adjustable wrench.

Step 8: Finish Up

Once the supply lines are connected to the faucets, you're almost finished. All that's left is to turn on the water and check for leaks. If there are any leaks, tighten the connections until they stop.

And there you have it! Installing a double sink in your bathroom is a relatively simple process that can be completed in a few hours. Just follow these steps and you'll be enjoying your new sink in no time!
