10 Genius Corner Cabinet Ideas for Bathrooms: Maximize every inch of your bathroom with these creative corner cabinet designs from my real-life projects.

The funniest (and most cringe-worthy) thing I ever did as a young designer was put a chunky, boxy cabinet in a client’s bathroom corner — it blocked the window, the door, and their mood. Lesson learned: corners are goldmines in small bathrooms, but only if you use them smartly. Over the years, I’ve seen how small spaces can spark big creativity, and today I want to share 10 bathroom corner cabinet ideas that have worked wonders in my projects.

1. Floating Corner Vanities

In tight bathrooms, a floating vanity tucked into the corner makes the room feel twice as airy. I once used room planner software to test different heights — it helped me find the perfect balance between storage and legroom.

2. Tall Slim Towers

Think of a vertical cabinet that reaches almost to the ceiling. It’s perfect for towels and extra toiletries, but beware – if the door opens into traffic space, you’ll curse it every morning.

3. Curved Corner Units

These soften lines visually and physically — no more hip bumping! They’re slightly more expensive to customize, but the comfort is priceless.

4. Open Corner Shelves

When storage needs are light, open corner shelving can make the space feel bigger while displaying pretty jars or plants. This works great with boho or minimalist styles.

5. Mirrored Corner Cabinets

A mirror-fronted cabinet kills two birds: extra storage and a bigger-looking bathroom. Just remember to keep the inside tidy — reflections are unforgiving.

6. Under-Sink L-Shaped Storage

By shaping the cabinetry under a corner sink into an L, you catch what’s usually wasted space. I once drafted this in my free floor plan creator to make sure the plumbing wouldn’t be a nightmare.

7. Pull-Out Corner Drawers

Instead of traditional doors, try drawers that angle out. They’re fun for kids to use, and you’ll find things faster — no more crouching to dig in the dark.

8. Over-Toilet Corner Storage

This one turns the awkward corner above the toilet into a storage superstar. Just make sure the cabinet depth doesn’t make sitting uncomfortable.

9. Corner Linen Closet

If you have the inches to spare, a shallow linen closet built into a bathroom corner can store way more than you think. For one project, I rendered it in a bathroom design tool to visualize how the doors would swing without hitting anything.

10. Recessed Wall Niches in Corners

Sometimes the best cabinet is no cabinet — a recessed niche in the corner for rolled towels or candles can be elegant and clutter-free. This trick works especially well in shower areas.
