Lose the Clutter
Many designers create a hotel spa look for their clients by emphasizing uncluttered lines. Under-counter sinks, a soaking tub and a separate shower with frameless glass are preferred. It's a contemporary look, but it also is warm and welcoming to come home to.
Light it Up
Natural light is an important part of the high-end spa and hotel bath experience. If you have a large windown in your bathroom, that is ultimately the best scenario, but if you don't have a large window, opt for window treatments that allow for privacy when you need it, but can easily be opened for the optimum natural light exposure.
