Well, there have been several posts on here in the past asking about "homemade cool rooms", and I thought I would share ours. We just got it finished last week, and are still putting on some of the finishing touches. I am not a big believer in cranking coolers down to 40 degrees (but they do grow hair O0) so ours is more of a tie area kept around 65-70 which makes a BIG difference when it is 90 outside. I basically designed it to be a nice place to have calves tied throughout the day, with fans and tie rails, just as if they were at a show. The room is 18x12, and has a plexiglass "viewing window" from the main aisle of the barn. The room will be used as a clipping room in the winter time, with the addition of lighting once we get the chance (lol)
