Interior Design by: TOC design. Project Manager: TOC design & Construction inc. Contractor: Ivco inc. Millworker: Soll Solutions. Photographer: Guillaume Gorini. Transitional bathrooms are defined as combining elements of one design era with those of another. Oftentimes the design elements are from adjacent eras, where one prevalent design and decoration style began to give way to another. A shower stall can also carry a transitional theme forward. An open format, stand-up shower with glass walls and doors strikes a particularly modern pose. By pairing this design with the traditional bearing of a large porcelain tiles, to add even greater visual interest, artisanal aesthetic and gravity to the design, different design influences and eras can be seamlessly incorporated. Mixing and matching modern or vintage toilet designs is also an option, as they too can create contrast with contemporary or traditional elements of a transitional design.
