[S.H. 1115B.4.4.5]

Exception: Where subject to excessive vandalism, two fixed shower heads shall be installed instead of a hand-held spray unit in facilities that are not transient lodging guest rooms. Each shower head shall be installed so it can be operated independently of the other and shall have swivel angle adjustments, both vertically and horizontally.

[2010 ADAS] EXCEPTION: A fixed shower head located at 48 inches (1220 mm) maximum above the shower finish floor shall be permitted instead of a hand-held spray unit in facilities that are not medical care facilities, long-term care facilities, transient lodging guest rooms, or residential dwelling units.

ETA Editor's Note

The 2010 ADAS Exception at 608.6 allows the installation of fixed shower heads at accessible showers in fewer locations than 2013 CBC. If hand-held units are subject to excessive vandalism at a medical care facility, long-term care facility or residential dwelling unit, 2013 CBC would allow the installation of fixed shower heads, while 2010 ADAS would not. However, the 2010 ADAS Exception does not require the consideration of excessive vandalism.

Thresholds in roll-in type shower compartments shall be ½ inch (12.7 mm) high maximum in accordance with Section 11B-303.

[2010 ADAS] EXCEPTION: A threshold 2 inches (51 mm) high maximum shall be permitted in transfer type shower compartments in existing facilities where provision of a ½ inch (13 mm) high threshold would disturb the structural reinforcement of the floor slab.

ETA Editor's Note

The 2013 CBC requirement for thresholds at accessible showers is more restrictive than 2010 ADAS.
