Designing a small bathroom comes with its challengesābut the right floor plan can turn tight quarters into a well-functioning, stylish space. Whether you’re working with a 5×7 layout, a corner bathroom, or a long and narrow room, how you place the tub, shower, sink, and toilet matters. The goal is to balance comfort, storage, and style without overcrowding. This guide presents 15 of the most efficient small bathroom floor plansāeach designed to help you make the most of your limited square footage while meeting your unique lifestyle needs.
1. 5×7 Bathroom with Shower and Single Vanity
This classic layout fits a walk-in shower, single vanity, and toilet into a compact 5×7 footprint. The shower is placed at one end, followed by the toilet, and a small vanity opposite. Itās efficient, cost-effective, and ideal for guest or secondary bathrooms.
2. Full Bathroom with Tub Along One Wall
In this layout, the bathtub, toilet, and vanity are all aligned along one wall to streamline plumbing. It works well in long, narrow bathrooms and leaves room for open space or a storage cabinet opposite the fixtures. Great for minimalist design lovers.
3. Corner Shower with Wall-Mounted Sink
This ultra-compact floor plan tucks the shower into a corner and saves space with a wall-mounted sink and a toilet beside it. It opens up the floor, making the space feel less crowded. Ideal for half-baths or powder rooms where every inch counts.
4. L-Shaped Layout with Pocket Door
This L-shaped plan divides the vanity and toilet from the shower, offering a more private feel. A pocket door saves space and provides better flow in tight quarters. Itās perfect for small primary bathrooms where separation enhances comfort.
5. Double Entry Bathroom
For homes with adjoining bedrooms, a shared bathroom with double entry points is efficient and family-friendly. Fixtures are arranged in a galley layout, with the sink and toilet on one side and the tub or shower opposite. Use sliding doors to maximize space.
6. Galley-Style with Shower at the End
This long and narrow floor plan uses a galley layout: vanity and toilet on one side, and a walk-in shower at the far end. Large mirrors and vertical storage help open up the space. Ideal for lofts or converted attics.
7. Tiny Square Bathroom with Central Toilet
For ultra-small spaces, place the toilet in the center with a corner shower and floating vanity on either side. This layout maintains a sense of balance and leaves room to move around. Compact and stylish, itās a favorite for micro-homes.
8. 3-in-a-Row Layout (TubāToiletāSink)
This popular plan places the tub, toilet, and sink in a straight line along one wall, simplifying plumbing and making installation easier. It’s efficient and easy to update with new finishes and fixtures when renovating.
9. Corner Tub with Angled Vanity
If you want a tub but lack width, a corner tub paired with an angled or curved vanity maximizes awkward spaces. This floor plan works well in asymmetrical bathrooms or those with slanted ceilings or corners to work around.
10. Split Wet and Dry Zones
This layout separates the wet zone (shower/tub) from the dry zone (sink/toilet) using a partial wall or glass divider. It improves functionality and prevents water from spreading. Great for small bathrooms that need a luxury touch.
11. Accessible Small Bathroom Plan
Designed for mobility needs, this layout uses wider doorways, a curbless shower, and a wall-mounted sink to create better access. The toilet is spaced appropriately, and fixtures are positioned for maneuverability. Ideal for aging-in-place designs.
12. Small Bathroom with Laundry Nook
Combine a bathroom and laundry area by tucking a stackable washer-dryer into a closet or alcove. Use a compact shower and vanity, and install overhead cabinets for storage. This dual-purpose layout works well in apartments or basement bathrooms.
13. Jack-and-Jill Layout for Small Bathrooms
This shared layout offers two entrances (often from bedrooms) and two separate sinks with a shared toilet and tub in the middle. Itās efficient for siblings or guest rooms and saves space while maintaining privacy and functionality.
14. Open Wet Room Design
This European-style floor plan uses a curbless, doorless shower that blends into the main bathroom floor. It’s easy to clean, highly modern, and great for very small spaces. Install a wall-hung toilet and floating sink to keep the floor open.
15. Compact Bathroom with Floating Fixtures
Mount the toilet and vanity on the wall to expose more floor area and make the room feel bigger. A frameless corner shower with clear glass completes the design. This layout is perfect for ultra-modern small bathrooms focused on maximizing visual space.
