Homeowner Don DeSantis wants to create a workout room, complete with a whirlpool tub, in the attic of his home, the eleventh Elmwood neighborhood project house. What was once an apartment will be turned into an open area. Next, Bob learns about the new rubber slate roof, before the hot tub is craned in and placed in the turret area. After a new SpacePak central air conditioning system is installed, Bob talks to Jan Jones (from Mr. Tub) about the new spa.
