10 Smart Bathroom Closet Ideas: Creative small-space bathroom closet inspirations from my 10+ years of design experience.

A client once asked me if we could fit a “walk-in” closet into her 3㎡ bathroom. At first, I laughed, but then I started sketching… and you know what? We did it! Sometimes, small spaces push us into our most creative solutions, and bathroom closets are a perfect example. Today, I’m sharing 10 bathroom closet ideas I’ve used in real homes — because small space doesn’t mean small style.

1. Recessed Wall Niches

Carving storage into the wall between studs can free up floor space instantly. I used this trick in a tiny apartment where we needed towel storage without blocking the shower door. A recessed niche with shelves gives you depth without the bulk, and if you style it with matching baskets, it looks 100% intentional.

2. Above-the-Toilet Cabinet

The space above the toilet is prime real estate for a shallow cabinet. I once designed a sleek wood cabinet over a client’s modern toilet, and it turned into her favorite spot for storing skincare. If you’re rethinking your entire layout, a thoughtful room plan can help find even more micro-storage spots.

3. Sliding Door Closets

A swinging door eats into your bathroom clearance. By using sliding doors — even better, mirrored ones — you get both storage and a sense of extra space. It’s a simple switch that feels surprisingly luxurious.

4. Tall Slim Cabinets

I love building tall cabinets that stretch nearly to the ceiling. They keep cleaning supplies away from kids and make the room look taller. Just measure carefully — small bathrooms rarely forgive bad proportions.

5. Open Shelf Towers

If you like a spa vibe, stack open shelves with rolled towels and baskets. I installed one for a beach house project, and it brought an airy, resort feel to a tiny bath. The trade-off: be ready to keep it styled and dust-free.

6. Under-Sink Pull-Outs

Most people waste the awkward space under their sink. Instead of random bins, I suggest custom pull-outs to make every corner accessible. During one remodel, we paired this with a precise layout plan to ensure plumbing didn’t block the mechanism.

7. Linen Closet with Glass Doors

Glass doors keep dust away while showing off your neat stacks of towels. Bonus points if you add interior lighting — it turns storage into a design feature, though you might have to fold a bit neater than usual.

8. Over-Door Shelf

Look up — there’s usually space above the bathroom door for a slim shelf. I’ve installed these for baskets of seasonal toiletries. It’s out of sight but easy to grab when needed.

9. Corner Built-Ins

Bare corners can hide a slim custom closet or shelves. In one narrow bath, we tucked a triangular cabinet into a wasted corner, and it held more than expected. Small fabric bins kept it all tidy, just as we mapped in our detailed bathroom design plan.

10. Floating Drawer Units

Floating drawers give the illusion of space by showing more floor area. I used one under a wall-mounted sink, and the client couldn’t believe how roomy her bathroom felt afterward.

FAQ

Q: How do I choose the right bathroom closet for a tiny space?

A: Start by measuring every nook and cranny — height is often overlooked. Then decide between open vs. closed storage depending on your tolerance for visual clutter.

Q: Is custom cabinetry worth it?

A: If your bathroom has awkward corners or tight plumbing clearances, custom work can maximize every centimeter — and in small spaces, that’s priceless.
