Luxury bathrooms, particularly those attached to master suites, are becoming more common in homes. In addition to being great places to relax and unwind, they can also significantly increase the resale value of your home.
One of the first decisions to make about a luxury bathroom is whether you want it to reflect the overall style of the home—or the master bedroom, if it's adjacent—or to present a style departure. Depending on the proximity of the luxury bathroom to the master suite, a drastic turn away from the overall style could create a jarring effect. On the other hand, subtle design flourishes can add tremendous personality to a luxury bathroom, and make it feel like its own space.
Something to keep in mind when planning a luxury bathroom, particularly if it's within or adjacent to a master suite, is that openness is your friend. Creating a flow between the master suite and luxury bathroom will make both spaces feel larger; it will also increase convenience in the overall space.
When it comes to fixtures like sinks and tubs, be inspired to "go big" in a luxury bathroom. Double sinks are often a must both for convenience and beauty; a large, standalone tub or whirlpool bath can act as a gorgeous and substantial focal point for the entire design. For the shower, consider extending the open feel by investing in an all-glass enclosure, or even an entirely open shower. If you've got the space, you can also enclose the toilet in its own nook, for added privacy.
Finally, consider adding a sitting area with a bench or chair for added beauty and convenience.
