My sister-in-law, Victoria Buker, is a landscape architect who works in construction management. When her master bathroom—untouched since the house was built in 1953—needed an upgrade, she recruited me to do the design, my brother-in-law, Dan Buker, to be the general contractor, and my wife, Katherine Buker, to install the tile.
