Note on Water Ports: If you choose the Center Back Wall Water Ports, the faucet will be offset to the right or left if using a 4" on center faucet. The tub will have 3 port holes exactly centered on the back wall for a 4" or 8" on center faucet. If you use a 8" on center faucet then the faucet will be centered because you will be using the outer 2 port holes. If you use a 4" on center faucet then you will be using the 2 right or left port holes. Stainless steel water port hole plugs are included to plug the port hole not in use. The plug matches the tub stainless.
