I am having an outdoor garage built. I am going to have a 5x6 or 5x7 cold storage closet put in for deer, vegetables and stuff. I have the option of having a floor drain installed with the concrete floor in the cooler pitched to the drain. This would add about $1500 to the cost. Seems like a lot. with deer potentially bleeding all over the floor it would make it easier to clean. Worth it or not?
