They also give you ample privacy and make it easier for two or more people to share a bathroom simultaneously. Considering these cons, you should skip the bathtub curtain and try a chic, spa-inspired bathroom design instead: wet rooms. This gives your bathroom an open layout, visually expanding its dimensions — a difficult feat to achieve when the square footage is limited. So, when properly installed and well ventilated, they're less prone to mold and mildew issues. That being said, these benefits come with a much higher price tag than a bathtub curtain, making them an expensive upgrade.
