Things to think about when designing a modern bathroom…wall mounted cabinets, curbless glass showers and free standing, sculptural bathtubs. Fewer seams! 9-foot porcelain slab panels can really translate that modern feeling.
If you really want to open up a space, add corner glass doors.
Floor to ceiling windows help to create that modern feeling. Thinner and larger spaced mullions may seem like a small detail but necessary if you are going for that modern look.
