Bathroom layout is constrained by plumbing—moving the toilet, shower, or sink involves major expense. Before planning any renovation, understand what's fixed in your space. If you're working with existing plumbing, your layout options are limited. If you're building new or doing a full gut renovation, you have more flexibility but should prioritize function over ambitious design that might create problems later.
Key clearance rules: allow at least 30 inches in front of each fixture, 24 inches beside the toilet (ideally on the open side, not the hinge side), and at least 36 inches between opposite-facing fixtures. Shower doors need swing clearance; sliding doors work better in tight spaces. Consider who uses the bathroom most: a primary bathroom shared by a couple needs different solutions than a kid-heavy household bathroom with less privacy needs.
Storage is typically the biggest challenge in bathrooms. Use vertical space with medicine cabinets and over-toilet shelving. Choose vanity storage over pedestals unless the floor plan absolutely requires minimal footprint. Glass shelves in showers provide storage without the cleaning challenges of caddies. Fresh towels and bathmats add color and warmth while serving obvious functions. Ventilation is non-negotiable—bathrooms need exhaust fans to prevent mold, and running the fan during and after showers makes a measurable difference.
