What is rough in opening for a standard bathtub?

The rough-in for a standard bathtub typically involves Plumbing connections for both water supply and drainage. The drain is usually positioned about 14 to 16 inches from the finished wall and 18 to 24 inches from the floor, depending on the tub design. Water supply lines should be placed approximately 3 to 4 inches above the finished floor and 6 to 8 inches apart, aligned with the faucet fittings. It's essential to ensure that all plumbing is properly secured and meets local building codes.
