I've thought about making up a frame out of 2x4s and then a trim board on the front and then either get some heavy duty metal brackets or make up a wood support out of 3/4' ply. I've seen lots of laminate tops in commercial buildings and the supports range from welded metal to custom wood to 'stock' wood supports.

The commercial bathrooms I've done we always used wall hung sinks or stone countertops and the stone guys always take care of the support. The goal is to create a safe and accessible bathroom environment that offers independence and comfort. The smallest permissible partition layout for ambulatory access is 60 inches deep and 35 inches wide. However, with careful planning, thoughtful design choices, and an understanding of ADA guidelines, it’s entirely possible. No problem with the countertop but I've never done an ADA support before. Designing a small ADA bathroom layout that is compliant, functional, and stylish can be a challenging task. He doesn't want to spend the money for granite so he wants a standard laminate counter. But then after thinking about it more he wants something nicer. My plumber suggested just 100 dollar wall hung sinks, 2 in each bathroom and the owner agreed. The Americans with Disabilities Act (ADA) sets specific guidelines for bathroom layouts to ensure accessibility for individuals with disabilities. Owner decided new stalls, then to tear out the tile on the walls, and on and on and on turned into a full gut. But has anyone built a frame of some sort for a commercial bathroom countertop? Or know of a place to order something? We are remodeling a restaurant and the bathrooms were just supposed to paint and new ceilings. Some other key commercial bathroom dimensions include: Partitions. Recommended to allow 1/2-1' gap between wall and partition for cleaning.

ADA requires at least one 59' deep stall. Not really a plumbing or carpentry question per say. Some other key commercial bathroom dimensions include: Partitions.
