How Pietra Grey Marble Performs in Wet Areas (Showers, Bathrooms & Spa Walls)
Introduction: Is Pietra Grey Marble Suitable for Bathrooms?
Pietra Grey Marble has become one of the most desired stones for luxury bathrooms, showers, spa walls, hotel suites, and wellness centers. Thanks to its deep grey base and fine white veining, it creates a sophisticated modern aesthetic — especially in contemporary hotel and residential design.
