We have a lean to that is legit, the size of a barn, and I would like to section off a part of the back to create an insulated stall for the colder winter months. I googled stall builds and I see these extravagant looking stalls that I would feel comfortable sleeping in, and I have no idea where to even start. Where does one find the metal bars that are used in these stalls? How big is too big, or is it possible to be too big? The lean to has a dirt ground, I've seen this before in some barn stalls, but I'm not sure if a rubber mat would be more appreciated by the horse? Is there a certain type of wood that is better than another when it comes to a stall build? We want to do this right!
