Give washing its own place in the layout
People may wash before eating or after work without using a toilet. Explain those activities when requesting a station. Keep it convenient and reachable, with room for users that does not obstruct the restroom entrance or the route used for supplies and servicing.
Match the support to the number of sessions
For repeating programmes, describe active hours and gaps. Ask how water, soap, towels and wastewater are managed for the offered station. Confirm the contact for replenishment or problems rather than assuming the initial setup will support every later session unchanged.
Where washing happens between activities
Place washing in the activity plan: beside the toilet group, near a shared break area, or wherever the property arrangement requires it. Describe simultaneous use, such as several groups finishing a session together. Ask which station configuration is proposed rather than assuming all units have the same number of washing positions.
Confirm who provides soap, drying supplies and water, and how replenishment and wastewater are handled. A freestanding station and a basin built into another unit can have different support needs. Resolve those responsibilities before comparing them as interchangeable choices.
Think through a transition such as a work break or the end of a programme session. If several groups wash together, mention that pattern rather than describing only the average number on site.
