This walk-in closet is perhaps 10x10...or more. The closet Island is about 2x2.5 with a tilt-down hamper behind the door. As islands go this is a small one but clearly has several functions - drawer, hamper and staging area.There are open shelves in the 'back' that aren't visible in this picture.
The recessed pedastal base has levelers on it to accomodate the out-of-level floors that we encounter in old ( and sometimes new) Boston housing.
In order to introduce an island the room should be of sufficient dimension to allow for a walk space of two feet (at a minimum) on all sides of the island.
Plan to spend $3000 ish for the two walls and the island.

thank you so very much! You gave such detailed information! I just moved to Idaho & my husband & I are in the process of buiding. We are "recreating" the home we built in Indiana... only I am fortunate to get a "Hers" closet. It will be 9ft 4" X 12ft I am so excited! The $3000 covers the drawers in the wall? It appears to have more than 2 walls finished. I will check to see if there is a Closet Sollutions in Coeur D'Alene/Hayden part of Idaho... great to know
