How to Measure Bathroom Plumbing Rough-In Dimensions for a New Vanity · Step 5 of 6
In this video
Move to the sink where you will install the assembled sensor valve. Connect the incoming hot supply line from the sensor valve to the hot water shutoff valve on the wall. Similarly, connect the incoming cold supply line to the cold water shutoff valve. Then, connect the two outgoing supply lines from the sensor valve to the corresponding hot and cold water inlets on the underside of the faucet. Tighten all four connections until they are snug.
Goal: Connect sensor valve to plumbing

FAQs
Is this project genuinely beginner-friendly, and can I expect to complete the measuring process within the estimated 3 hours?
Yes, this project is well-suited for beginners as it primarily involves careful measuring and marking, not actual plumbing installation. The 3-hour estimate is realistic, assuming you have all your tools and the new vanity's specifications readily available. Accuracy is more important than speed for this step.
Do I need the specific brand-name tape measures listed, or can I use a standard measuring tape and level?
While specific brands are listed for tools, any standard, accurate 25 ft. tape measure and a reliable 2-foot level will work perfectly. The critical factor is ensuring your tools are in good working order and provide clear, precise readings for accurate marking on the wall.
What are the most critical measurements to double-check to avoid costly errors during the rough-in process?
The most critical measurements are the vanity's centerline, the height and horizontal spacing of the drain pipe, and the hot/cold supply lines. Always double-check these against your new vanity's internal dimensions, especially where the sink basin, P-trap, and supply lines will connect, to ensure everything fits without obstruction.
Before marking the wall, should I take any precautions regarding existing pipes or electrical wiring that might be behind the drywall?
While you are only marking the wall, it's a good practice to use a stud finder with AC detection to identify potential electrical lines or hidden studs. This awareness can help you avoid marking directly over sensitive areas, which is beneficial if you later need to cut into the wall for actual plumbing work.
