This article will delve into the essential aspects of how to rough in plumbing for a bathroom vanity, providing a comprehensive guide for DIY enthusiasts and professionals alike.

Planning and Measurements

Before starting, it's crucial to plan the layout of your bathroom vanity and determine the exact location of the sink, faucet, and drain. Measure the distance between the center of the drain and the wall to establish the placement of the water supply lines and drain pipe.

Materials and Tools

Gather the necessary materials and tools, including copper pipes, fittings, valves, PEX tubing, a drainpipe, a basin wrench, a pipe cutter, and a level. Ensure that the materials meet the required codes and standards for your area.

Installing Water Supply Lines

Cut the copper pipes to the desired lengths and connect them using fittings. Install shut-off valves at the base of each water supply line to control the water flow. Use PEX tubing to connect the water supply lines to the sink's faucet and supply stops.

Installing Drainpipe

Connect the drainpipe to the sink's tailpiece and secure it with a slip nut. Use a level to ensure that the drainpipe slopes slightly downwards towards the main drain line. This prevents water from accumulating and causing clogs.

Connecting to Main Drain

Connect the drainpipe to the main drain line using a tee fitting. Ensure that the connection is secure and watertight to prevent leaks. Use a drainpipe cleanout to facilitate future maintenance and access.

Testing and Inspection

Once the plumbing is complete, test the water supply lines and drainpipe for leaks. Run water through the sink and check for any issues. Inspect the connections and fittings to ensure they are tight and secure. If any leaks or problems arise, adjust and repair accordingly.

Conclusion

Roughing in plumbing for a bathroom vanity requires careful planning, precise measurements, and the proper materials and tools. By following the steps outlined in this article, you can ensure a well-functioning plumbing system that will support your bathroom vanity and fixtures for years to come.
