(a) Except as otherwise provided in section 7040.6(a) of this Part, each individual occupancy housing unit shall contain at least 60 square feet of floor space; however, an individual occupancy housing unit may contain less than 60 square feet of floor space if such unit was originally constructed for single occupancy prior to the effective date of this Part.

(c) Sufficient showers shall be available to permit each inmate to shower daily, pursuant to the requirements of section 7005.2 of this Title.
