Yep, the condensate from the units doesn’t always drain properly, and the floor takes a beating. Over time the plastic liner cracks. When I cut the old out, and replaced with new carbon steel. I first used POR paint, then laid fiberglass with epoxy over that. It may rust out from under sometime in the future but I am confident it won’t fail from the top.

Using stainless was a great idea.
