5 Smart Bathroom Cupboard Designs: Creative Storage Solutions for Small Bathrooms Inspired by Real Projects

Over the past decade, I’ve seen bathroom design trends shift towards cleaner, smarter layouts, with storage being a central focus. Small spaces often inspire big ideas — and nowhere is this more true than in bathroom cupboard design. In this guide, I’ll share 5 bathroom cupboard design inspirations, each drawn from my real projects and supported by expert insights, aimed at helping you transform your space without losing functionality.

Minimalist Floating Cabinets

My Take: I love using floating cupboards in bathrooms because they visually expand the floor space. My first apartment had one, and it instantly made my small bathroom feel more spacious.

Pros: Easy to clean underneath, creates a light and airy feel, and works great with long-tail keywords like "modern small bathroom cupboard design." According to the National Kitchen & Bath Association (NKBA), wall-mounted storage can increase visual space perception by up to 15%.

Cons: Limited storage depth; you can’t load it with heavy items, and installation might require reinforced walls.

Tip: Pair with concealed LED lighting underneath for a high-end look. See how glass backsplash makes the bathroom more open in one of my favorite case studies.

Built-in Tall Cupboards

My Take: In one client’s loft bathroom, we built a floor-to-ceiling cupboard into an alcove. It became the perfect spot for towels, toiletries, and even cleaning supplies.

Pros: Maximizes vertical storage, helps in organizing different items, and blends seamlessly with existing walls. It’s ideal for narrow spaces where every inch counts.

Cons: Might require custom carpentry, and moving plumbing to fit the design can add cost.

Case note: Using recessed handles can keep the look clean while preventing accidental knocks.

Open Shelving with Cupboard Mix

My Take: I’ve found combining open shelves with closed cupboards gives the best of both worlds — quick access for daily items and hidden storage for the rest.

Pros: Adds decorative display opportunities, improves style personalization, and matches the trend towards mixed-material bathroom cupboard designs.

Cons: Requires consistent tidying to avoid clutter; dust can be a minor issue if shelves are too open.

Example: We used oak shelves above a closed under-sink cabinet in a recent project, very similar to an wood accents bringing warmth approach I often recommend.

Corner Cupboards

My Take: Corners are often wasted in bathroom design — but in a recent renovation, we installed a triangular cupboard that neatly tucked into an unused corner.

Pros: Utilizes dead space, offers discreet storage, and works well in irregular-shaped bathrooms.

Cons: Not suitable for large storage needs; custom fitting can be tricky.

Tip: If budget is tight, consider semi-custom options to save on craftsmanship costs.

Mirror-front Cupboards

My Take: In my own home, I replaced a plain mirror with a mirrored cupboard. It gave me hidden storage without sacrificing the reflective surface that makes the bathroom look bigger.

Pros: Dual-function design, keeps toiletries out of sight, and reflects light for an airy feel; great for modern compact bathrooms.

Cons: Mirrors require regular cleaning, and hinges need to be strong to support the weight.

Cost tip: Frameless styles tend to be more expensive than framed versions, but they look sleeker. I documented a project where L-shaped layout frees countertop space in conjunction with these cupboards.
