Travertine, a natural limestone which is marbled with impurities such as iron, is a natural choice for tiling bathrooms, floors and even kitchen countertops. Travertine is a "beautiful and timeless choice," says Lynnelle Caudill, General Manager of the Davenport Hotel and Tower. During the 2000 restoration of the historic hotel, travertine was installed in the Davenport's rooms. Now, Caudill says, it's been installed in the new Davenport Tower.
