Our wash stall is unique. It doesn’t have a floor drain. Instead, the concrete floor is graded with 4 inches of fall toward the outside and 3 inches, side to side. This helps runoff flush cleanly off the rubber mats and through the exterior door.
This means no clogs, no standing water and most importantly, no drain in the middle of the floor to try and keep clean. Chilly after a bath? Of course our wash stall is heated!
