things i learned is:
1) you will never have enough room no matter how big the room is (mine is 14x14)
2) PUT A FLOOR DRAIN IN (no I dont have one and im still kicking myself for not adding it)
3) you will never have enough plugs or dedicated circuits
4) utility sink
5) I had a window unit and a dehumidifier which added a lot of heat, I changed to a portable a/c which keeps the room cooler and less humidity. plus no dripping water outside which accumulates pretty fast
6) insulate the walls
