What is the best bathroom layout for a small 5x8 bathroom?

For a 5x8 bathroom (40 square feet), the most efficient layout is typically a single-wall or galley design that maximizes the 8-foot length while keeping the narrow 5-foot width functional. This compact size requires strategic placement of fixtures to meet Ontario Building Code clearances while maintaining usability.

The optimal layout places the toilet at one end with the required 15 inches from centerline to any wall, followed by a vanity (24-30 inches wide works best), and a shower or tub at the opposite end. This linear arrangement along one wall leaves the narrow walkway clear and meets OBC requirements for minimum clearances. In Ottawa homes, we often see this configuration in older houses where bathrooms were carved out of existing bedroom space.

Door placement is crucial in this size bathroom. The door should ideally open outward or be a pocket door to avoid swing interference with fixtures. If the door must swing inward, position it so it doesn't hit the toilet or vanity. Many Ottawa homeowners opt for a 30-inch vanity rather than 36-inch to ensure comfortable door operation, and this still provides adequate storage for a small family.

For the shower versus tub decision, consider your household needs and resale value. A 32x60-inch shower with glass doors feels more spacious than a standard tub/shower combo and is easier to clean. However, if this is your only bathroom and you have young children, a tub might be necessary. Corner showers can work but often feel cramped in a 5-foot width - stick with a standard alcove design.

Storage solutions become critical in small bathrooms. A vanity with drawers rather than doors maximizes storage efficiency. Consider a medicine cabinet that's recessed into the wall rather than surface-mounted, and add a small linen closet if you're doing structural work. Niches in the shower wall provide storage without eating into floor space.

Lighting and ventilation can make this small space feel larger. A good exhaust fan (minimum 50 CFM for this size) is required by Ontario Building Code, and proper lighting - including task lighting at the vanity - prevents the space from feeling cave-like. Many Ottawa homes benefit from adding a skylight if the bathroom is on the top floor.

Professional considerations: While homeowners can handle cosmetic updates, any changes to plumbing locations, electrical, or ventilation require permits through the City of Ottawa. Moving a toilet or shower drain involves significant work and costs $3,000-$6,000 in Ottawa's market. Sometimes working with the existing plumbing layout and focusing on better fixtures and finishes gives you more value for your renovation budget.

For a complete renovation of a 5x8 bathroom in Ottawa, expect to invest $18,000-$35,000 depending on fixture quality and whether plumbing moves are required. Want to discuss your specific layout challenges? We offer free consultations to help optimize small bathroom spaces.
