Classic and Sentry Washfountains
Capacities and Space Requirements

Classic and Sentry Washfountain Capacities

Most building codes and OSHA have accepted 20" of curved wash fountain rim as equal to one lavatory.

This ratio has been proven satisfactory over years of usage. A ratio of one wash-up station for each of 5–6 users has proven desirable for factories and other installations where fast washup is required. See the
table to the right for total washfountain capacities based on 1 station for each of 5–6 users (1:5–6).

Classic and Sentry Washfountain Space Requirements

Washfountains require less floor space than an equivalent number of lavatories. Semi-circular washfountains will fit in long, narrow washrooms equally well as lavatories. Circular washfountains work well in large change rooms or corridor installations. The corner washfountain makes use of wasted space. See Figures 1 and 2 below for a space comparison between conventional lavatories versus Classic and Sentry washfountain configurations.

Figure 1

Three 20" x 18" conventional lavatories on 30" centers versus one 36" semi-circular washfountain:

• Washfountain space requirements - 18 square feet including 24" of "people space" around rim.
• Conventional lavatories space requirements - 22 square feet including 24" of "people space" and   4" cleaning clearance on sides.

Figure 2

Four 20" x 18" conventional lavatories on 30" centers versus one 54" semi-circular washfountain:

• Washfountain space requirements—28 square feet including 24" of "people space" around rim.
• Conventional lavatories space requirements—36 square feet including 24" of "people space" and    4" cleaning clearance on sides.

Classic and Sentry Washfountain Minimum Practical Clearances

Classic and Sentry washfountains should have a clearance of 48" between washfountains, and 24" from the front or side of the washfountain to the wall (see Figures 3 and 4 below).
