Cluster
Also called: bank of units, restroom bank, toilet block
A cluster is a group of portable toilets placed together at one location, often with a handwash station and a light. Events use several clusters spread across the site rather than one large bank, and the ADA percentage rule applies to each cluster.
Clusters shorten queues because guests spread out, and they keep any one spot from being overwhelmed. A common rule at large events is to place clusters so that no guest walks more than a few minutes to reach one.
Each cluster needs its own truck access and its own accessible unit where the ADA applies.
