SECTION
11B-805 Medical care and long-term care facilities
11B-805.6 Handwashing fixtures, lavatories and sinks. All handwashing fixtures, lavatories and sinks shall comply with Section 11B-606.
Exception: Scrub sinks, as defined in California Plumbing Code Section 221.0, shall not be required to comply with Section 11B-606.
INTERPRETATION
The requirements of Section 11B-606 apply to all lavatories, sinks, and handwashing fixtures for public use, patient use, and employee use, unless otherwise specifically exempted by the code. Lavatories, sinks, and handwashing fixtures are common use areas and therefore, require accessibility.
Exceptions:
• Scrub sinks (due to impracticality)
• Specific workstations (see Section 11B-203.9). This applies only where the sink is the actual workstation.
Knee clearance requirement - All accessibility requirements of Section 11B-606 apply to lavatories, sinks, and handwashing fixtures required to be accessible. Lavatories are subject to Section 11B-306.3.3, Exception 1 which states: "At lavatories required to be accessible by Section 11B-213.3.4, the knee clearance shall be 27 inches (686 mm) high minimum above the finish floor or ground at a depth of 8 inches (203 mm) minimum increasing to 29 inches (737 mm) high minimum above the finish floor or ground at the front edge of a counter with a built-in lavatory or at the front edge of a wall-mounted lavatory fixture."
This requirement applies to all lavatories. "Handwashing fixtures" are special application "sinks" and not subject to the exception. Handwashing fixtures, as sinks, are subject to Section 11B- 306.2.3, Exception 1 which states: "The toe clearance shall extend 19 inches minimum under sinks required to be accessible by Section 11B-212.3."
Consequently, handwashing fixtures must have a minimum depth of 19 inches in order to comply with the minimum toe clearance. They shall also have a minimum knee clearance of 27 inches at the depth and reduction described in Sections 11B-306.3.3 and 11B-306.3.4.
