I'm buying a diamond bar box for my house and the room is barely big enough. Diamond recommends that the minimum space requirements are 13 ft x 16.5 ft. My actual room is 14'-5" x 17'-3". According to Diamond I have enough room however it doesn't seem like enough to me. There is only going to be between 4'-5" to 4'-11" of space between the edge of the table and the wall. What do you guys think?
