Residential remodel crew of about 20: sanitizer on the unit enough, or add a handwash station?
We're starting a residential remodel next week with a crew that sits around 18 to 22 people depending on the day. Ordering a standard unit for the driveway so nobody walks through the house bathroom. The quote includes the toilet with a wall hand sanitizer dispenser, and they offered a standalone handwash station as an add-on.

OSHA talks about washing facilities on construction sites, but I'm not clear whether sanitizer on the unit covers a mid-size residential job or if we need soap and water for the crew. We'll have dust and some paint work, so people will want to clean up before lunch.
Anyone run a similar crew size with just the sanitizer, or did you end up adding the handwash station? Truck can reach the driveway fine for weekly service.
