(SPS 384.20(5)(o)4.)Urinals: At least 15″ from centerline to side wall and 30″ between urinals. (SPS 384.20(5)(n)2.)Showers: Minimum 900 in² interior that can encompass a 30″ diameter circle. (SPS 384.20(5)(L)4.)Code = technical performance and basic spacing so fixtures work.ADA Standards (2010, Chapter 6 – Plumbing Elements & Facilities)Water closet centerline: 16–18″ from side wall (accessible stalls).Clear floor space at WC: 60″ wide × 56″ deep (wall-hung) or 59″ deep (floor-mounted).Seat height: 17–19″ AFF.Grab bars: 42″ side wall bar and 36″ rear bar at 33–36″ AFF (specific start/extent requirements).TP dispenser: 7–9″ in front of bowl, 15–48″ AFF, not blocked by bars.Lavatories: Max rim 34″ AFF, 27″ minimum knee clearance, 30″×48″ clear floor space.ADA = installation standards so fixtures are usable for everyone (independence, safety, dignity).Why we install to ADADignity & independence: Proper clearances let people use restrooms without assistance.Risk & cost: Avoids complaints, litigation, and expensive retrofits later.Broader usability: Benefits older adults, people with temporary injuries, and caregivers.Team sport: Even when plumbers don’t set grab bars/TP holders, we can flag missing blocking, off dims, and coordination issues so the whole project stays compliant.ReferencesU.S. Access Board – ADA Standards, Chapter 6 (Plumbing Elements & Facilities): https://www.access-board.gov/ada/chapter-6-plumbing-elements-and-facilities/Wisconsin Administrative Code – SPS 384.20 (Plumbing Fixtures): https://docs.legis.wisconsin.gov/code/admin_code/sps/safety_and_buildings_and_environment/380_387/384/II/20Support the show
