Unlike a house, the bathrooms in Accessory Dwelling Units (ADUs) are usually smaller but still play a pivotal role in the overall functionality and appeal of these compact living spaces. Whether you’re planning an ADU as a rental, a guest house, or a personal retreat, the bathroom design requires special attention to maximize utility, comfort, and aesthetics. Here’s a guide to help you design a bathroom that perfectly complements your ADU.

1. Prioritize Space Efficiency

Space is often at a premium in ADUs, so your bathroom design should focus on smart layouts and compact fixtures. Consider these ideas:

• Pocket Doors: Replace swinging doors with pocket doors to save floor space.
• Corner Fixtures: Use corner sinks and toilets to optimize awkward spaces.
• Shower-Tub Combos: If space allows, a compact shower-tub combo can add versatility without sacrificing too much room.

2. Use Light Colors to Open Up the Space

Light, neutral colors can make small bathrooms feel larger. Consider:

• Soft whites, light greys, or pastel tones for walls.
• Large-format tiles to minimize grout lines and create a seamless look.
• Strategically placed mirrors to reflect light and give the illusion of a bigger room.

3. Maximize Storage

Storage is essential in any bathroom, but even more so in an ADU where space is limited. Use:

• Built-In Shelving: Install recessed shelves in the shower or above the toilet.
• Floating Vanities: These can create a modern look while keeping the floor space open.
• Multipurpose Mirrors: Choose mirrors with built-in cabinets for added storage.

4. Choose Fixtures for Function and Style

Compact, stylish fixtures are key to a well-designed ADU bathroom:

• Wall-Mounted Toilets: These save space and offer a sleek, modern aesthetic.
• Pedestal or Floating Sinks: These reduce the footprint while still being functional.
• Efficient Showerheads and Faucets: Consider water-saving fixtures to keep utility costs low.

5. Focus on Accessibility

If your ADU is intended for aging parents or potential tenants, accessibility should be a priority. Think about:

• A curbless shower design for easy entry.
• Grab bars near the toilet and in the shower for added safety.
• Lever-style faucets and door handles for ease of use.

6. Add Personal Touches

Bathrooms in ADUs should feel welcoming and cohesive with the rest of the space. Incorporate:

• Custom Tiles: A patterned backsplash or unique shower tiles can serve as a focal point.
• Plants: Small, moisture-loving plants like ferns or pothos can add a natural touch.
• Lighting: Layered lighting, such as sconces and overhead fixtures, can create a relaxing atmosphere.

7. Budget-Friendly Tips

ADUs often have tight budgets, so keep costs manageable by:

• Opting for prefabricated shower units instead of custom designs.
• Choosing durable, affordable materials like porcelain tiles and fiberglass fixtures.
• Repurposing or upcycling materials to create a unique, eco-friendly space.

Conclusion

Designing a bathroom for an ADU is all about striking the right balance between functionality, aesthetics, and space optimization. With thoughtful planning and creative solutions, you can create a stylish and practical bathroom that enhances the livability of your ADU. Whether you’re working with a designer or tackling it as a DIY project, keep these tips in mind to bring your vision to life.
