That particular room that belongs to a guy has one thing in common to every other guys room. That one most common feature is that all of them are different. This room belongs to a guy. It does not belong to the neighbors, his wife, the kids, no one else. The thing about every man cave decor is specificity to his needs and wants.

The room, itself, is designed and decorated to reflect his interests. Those interests may be sports or hobbies. They may just be the luxury. They could be very masculine or frilly, again, depending on what the guy is into. When looking at some of them, you will notice a trend that is specific and special to each guy. This will be different that any other space in the house.

The reason he has created this room might be to enjoy sports by himself or with close friends. In this particular case, the decorations will revolve around a large television. It might be a flat screen or not, but it will have the larger than normal speakers so he can be right in the middle of it.

The thing he likes to do in his off hours might be woodworking. This entails a large table just for this type of work he will want to have a tool bench as well as a pegboard or two to hang his tools and other supplies. The addition of more electrical outlets will assist in this hobby.

Maybe reading is his main claim to fame. He will certainly need many bookshelves to hold his tomes in. He will need good lighting, right next to his easy chair. He may have a rack that holds magazines and an electronic reader to save money on some purchases.

In any case, there will probably be carpets and throw rugs for accents. There will be posters on the walls that facilitate information about whatever he in into. That means sports posters, illustrations for various woodworking joints and special placards for precautions dealing with glue, varnish, or visuals about any other hobbies.

If he is into coin collecting, he will need a nice table and good chair. Lighting will have to be positioned so he can inspect the coins in the right light. Magnifying glasses will have to be stored in a drawer along with coin holders and alcohol wipes. Shelving will help him display some of his nicest pieces and a safe may be needed for some of the most valuable items in is inventory.

This room is special to that guy. It does not have to measure up for anyone else. It has the things in it that makes sense to him and he is the sole occupant at any one point in time. The man cave is a special thing that only makes sense when you realize it has this purpose and no other. It might really be a separate structure such as a shed out back.
