Plumbing a bathroom can seem like a daunting task, but it's actually a manageable project for homeowners with basic plumbing knowledge. With the right tools and materials, you can save significant money by completing this task yourself. This comprehensive guide will provide you with step-by-step instructions and free plumbing diagrams to ensure a successful bathroom plumbing installation.

Step 1: Gather Tools and Materials

Before starting, gather all necessary tools and materials, including:

Pipe wrench or pliers
Adjustable wrench
Basin wrench
Cordless drill
Measuring tape
Level
Teflon tape
Plumber's putty
PVC or PEX pipes and fittings
Drain traps
Toilet flange
Shower head and valve
Faucet and valve

Step 2: Turn Off Water Supply

Locate the main water shut-off valve, usually found near the water meter or under the sink. Close the valve to stop the flow of water.

Step 3: Remove Old Fixtures

Use a wrench to disconnect the water supply lines and drain lines from the bathroom fixtures. Unscrew and remove the old fixtures, including the toilet, sink, showerhead, and faucet.

Step 4: Install Drain Traps

Connect the drain traps to the drains and seal them with plumber's putty. Ensure the traps are properly aligned to prevent water backup.

Step 5: Install Toilet Flange

Position the toilet flange over the drain line and secure it with screws. Seal around the flange with plumber's putty.

Step 6: Install Toilet

Place the toilet on the flange and tighten the bolts to secure it. Connect the water supply line to the toilet fill valve.

Step 7: Install Sink

Place the sink on the vanity or countertop and connect the drain line and water supply lines. Secure the sink with bolts or brackets.

Step 8: Install Showerhead and Valve

Attach the showerhead to the shower arm and connect the water supply lines to the valve. Use Teflon tape to seal the connections.

Step 9: Install Faucet

Mount the faucet to the sink and connect the water supply lines. Secure the faucet with bolts or nuts.

Step 10: Turn On Water Supply

Slowly open the main water shut-off valve and check for any leaks. If no leaks are found, turn on the faucets and shower to test the system.
