Just go to our website and click here to see our options. You will see freestanding waterlines for baths that do not have holes for the faucet. You will also see straight water lines - these are for the baths that have 7" on center holes for a deck mount faucet. Otherwise, you will need an offset water supply line. This is used for a faucet that mounts on the wall of a bathtub. They are beautifully contoured from an 8" center bottom to a slim 3-3/8" on center.
