Yes. A waterproof shower curtain liner must be used at all times when showering to help prevent water from escaping the tub or shower area.

Failure to properly use a shower curtain liner may result in water damage to walls, flooring, ceilings, cabinetry, and surrounding areas. Residents are responsible for any damage caused by the misuse or non-use of a shower curtain liner, including flooding or moisture-related damage.
