Stone and tile specialist Nick Tagios returns to install the countertop on the kitchen island in the penthouse apartment. Tagios takes us through all the steps of bracing and epoxying the Pietra Cardosa marble surface. Next, Bob checks on the trimwork being done in the back bedroom. Bob also looks on as the sliding closet doors and shelving are installed. Finally, work is also underway in the bathroom, and Lenora Campos from Toto is on-site to show off the new fixtures that are part of Toto's Mercer suite.
