RETAIL STORES

The minimum fixture requirements for retail stores differ from the examples that we have just been working with. However, the concept and approach of computing the needs is same. Refer to Figure 9.3 for listings that pertain to retail stores. You can see that the table is very similar, in layout, to the one we have just been using. Pay particular attention to the number 6 at the heading of retail stores. Refer back to Figure 9.2 for an explanation of the note. You will find that one bathroom facility can be used by both males and females in certain types of occupancies. For example, an office with 1200 square feet, or less, can be served by a single restroom for both sexes. A retail store with 1500 square feet, or less, can also be served by one rest­room, unless the store is classified as a service station. Other types of build­ings that may qualify for a single bathroom are restaurants, self-service laun­dries, beauty salons, and barber shops. In all cases, the use of a single restroom is contingent on the square footage of the building. With this said, let’s run through a sample sizing example.

Assume that our sample building will accommodate 59 people. Use the table in Figure 9.3 to determine the minimum number of plumbing fixtures required. For the purposes of this exercise, assume that the single-bath­room rule is not applicable. Go ahead, run the numbers, and then compare them with mine.

You should have found that the male restroom requires two water closets. A total of three water closets is needed for the female restroom. The male restroom is required to have only one lavatory, but the female restroom is re­quired to have three lavatories. Only one drinking fountain is needed, subject to building design. By this, I mean that a drinking fountain is required on each
