Who: Jenna B.
Where: Wayne, Pa.
We did all of the work ourselves, including plumbing and electricity, so it took us nearly eight months, but it was well worth the wait. We enlarged the space immensely by overtaking one closet in the master bedroom and another in an adjacent guest room. We gutted everything down to the studs and floorboards and installed new radiant-heat floors, a double vanity, Carrara marble nearly everywhere, a beautiful chandelier, and a rain shower. What people are most amazed about when they visit, however, are the televisions hidden behind the mirrors, which you can only see when they're turned on.
Who did the work: I did all the work myself.
Cost: $10,000 to $25,000
