No, Patsy's paint tote was not in the "boiler room," but next to it. If you look closely, you can see the door to the "wine cellar" is part of a narrow hallway separate from the "boiler room," which has it's own door. When looking at photos of the area, it's easier to see than in the floor plan because the photos show the boiler room door closed, as opposed to the floor plan. Apparently, the paint tote was sitting close to the door next to a piece of carpet. That's where the urine stain was found (and confirmed by Kolar when asked on Tricia's radio show).
