Step 3 · Remove Old Faucet Components
With the supply lines detached, the next task is to remove the hardware securing the faucet to the tub deck. Each component (hot handle, cold handle, spout) is held in place by a large mounting nut on its underside. Use the basin wrench to grip these nuts and turn them counter-clockwise to loosen and remove them. This can be the most difficult step due to corrosion and limited leverage. Once all nuts and any associated washers or brackets are removed, have a helper lift the old faucet components straight up and out from the top of the tub deck.
