You’re pretty lucky if you have a large enough window in your bathroom that could use a seating area right beneath it. A bathroom reno featured on Beneath My Heart uses an upholstered loveseat bench with added accent pillows for the window area. How about a built-in? This vanity featured on Home Bunch has a bench area near the window, while this other example (also from Home Bunch) creates a window seat out of a bathroom storage unit. You could also try a bathroom storage unit on a much larger scale with a bench as well, like the third option below from BHG. Built-ins are great, but they’re not for everyone. You could try a simple wicker bench with an elegant cushion to place by your bathroom window, like the one below featured on House of Turquoise.
A vanity bench can always help if you spend a lot of time in the bathroom putting on makeup or doing your hair. Have a look at this incredibly elegant tufted bench from Alice Lane Home that could do the trick. A more compact option is a simple stool, like this gorgeously elegant selection (again from Home Bunch) that matches the style of this bathroom. This vanity from APD Architects actually has its own seated area, with a matching cushioned stool. Even a regular ottoman can work in a bathroom. This one featured on HGTV has a space against a wall right across from the vanity. This next very interesting bench featured on BHG stems out from the vanity beside it, where there’s a window. If the size and architecture of your bathroom make it work, then why not?
