What constitutes a bedroom as a master? Typically, it's the largest room in the house. Some would argue an en-suite is what gives the room its title. But there’s more than the checked boxes that makes this room a sacred space — it’s the little pieces that come together to achieve a personalized, peaceful state of mind.

Whether you live in a small studio or massive mansion, everyone’s master bedroom deserves to be a retreat away from his or her busy lives. These hideaways come in all shapes and colors. There is no one size fits all. Check out these masters that made the mark, and get inspired to give your retreat a major refresh.

SLHL Tip: If you have space, make it multi-functional. What about a space brings you peace? Whether it’s a treadmill to run off steam, artwork that evokes a sense of nostalgia or a reading nook for a cozy place to sink into a good book, incorporate it into your design.
