See How These 8 Bathrooms Fit It All Into About 100 Square Feet

If you want a bathroom with a stand-alone bathtub, separate shower, double vanity and toilet or water closet, you’re looking at 100 square feet, give or take. That figure is based on the standard dimensions of each of those elements, plus the space you’ll need for meeting code requirements and moving through the room.

Designer John Conroy says this size is popular for a bathroom because it gives you the biggest bang for your buck. In other words, you can get the features you want while being able to include things like marble tile, a higher-end countertop material and radiant floor heating. Once you go bigger than that, “the square-foot dollar amount adds up very quickly,” Conroy says. “With 100 square feet, you’re making your budget go further.”

With that in mind, we decided to take a look at eight bathrooms that fall around the 100-square-foot mark — some smaller, some bigger — and see how layouts, materials, style and, most important, costs were handled in the space.

Style: Berghuis says he enjoys working with contemporary style in midsize bathrooms because the clean lines and floating elements give the appearance of
