When you're designing a bathroom, one of the most important things to get right is the clearance around your fixtures. After all, nobody wants to feel cramped when they're brushing their teeth or using the toilet. Generally, you'll want to have at least 15” of space from the center of any fixture—like your toilet, sink, or shower—to the nearest wall or another fixture. This gives you enough room to move comfortably. On top of that, you'll need at least 21” of space in front of each fixture so you're not squeezing through tight spots. And don't forget about those doors or cabinets—make sure there's at least 24” of clearance in front of any openings to avoid any awkward bumps.
