Step 2 · Measure Plumbing for Shield Fitment
Using a flexible tape measure, take precise measurements of all plumbing components that will be covered. Measure the length of the P-trap U-bend. Measure the vertical sink tailpiece from the sink drain down to the P-trap inlet. Measure the horizontal trap arm from the P-trap outlet to the sanitary tee connection in the wall. Finally, measure the hot and cold water supply lines, from the top of the angle stop valve body up to the faucet connection nut. Write down all measurements on a notepad to reference when cutting.
