Small Bathroom Storage Ideas That Actually Work (2026 Guide)

If your bathroom feels like it's bursting at the seams — towels on the floor, toiletries crowding the sink, no room for anything — you're not alone. Most homes in London, Ontario were built with bathrooms that prioritized plumbing over storage. The good news? You don't always need to gut the room to fix it. Sometimes the right renovation choices can double your usable storage without adding a single square foot.

Here are the small bathroom storage ideas we recommend most to homeowners across London, ON.

1. Swap Your Vanity for One With Built-In Storage

The single biggest storage upgrade in a small bathroom is replacing a pedestal sink or an outdated vanity with a modern one that has deep drawers and cabinet space underneath. A well-designed 30–36" vanity can hold an enormous amount — and keep all of it hidden.

What to look for:

• Deep bottom drawer for hairdryers and bulky items
• Divided inner drawers for small toiletries
• Soft-close doors and drawers — they last longer and feel higher quality
• Floating vanity — mounting it off the floor creates visual space and makes the room feel larger

At Bath Tune-Up West London, vanity upgrades are one of our most popular standalone projects. We can often complete a vanity swap in a single day.

2. Build a Niche Into Your Shower

A recessed shower niche — a built-in shelf cut into the wall between studs — is one of the smartest storage moves you can make during a bathroom renovation. It holds shampoo, conditioner, and soap without taking up any floor or wall space. No shower caddy hanging from the showerhead. No bottles cluttering the tub edge.

Niches can be tiled to match your shower surround and sized to fit your specific products. We build them into nearly every shower project we do, and homeowners always wish they'd done it sooner.

3. Go Vertical With Wall-Mounted Shelving

When floor space is limited, the answer is up. Open shelving above the toilet, beside the vanity, or in a corner can hold a surprising amount — rolled towels, baskets, candles, and everyday items — without eating into your walking space.

Options that work well in small bathrooms:

• Floating shelves — minimal and clean, easy to install
• Over-toilet étagères — freestanding towers that use otherwise wasted space
• Recessed medicine cabinet — flush with the wall so it doesn't protrude; far more storage than a standard mirror

4. Use the Space Behind the Door

The back of your bathroom door is prime real estate that most people completely ignore. An over-door organizer or a few well-placed hooks can hold robes, towels, hair tools, or a small shelf for products — all without touching your walls.

For a cleaner look, consider having hooks installed directly into the door at the right height for your household.

5. Replace Your Mirror With a Medicine Cabinet

A standard bathroom mirror does one job. A recessed medicine cabinet does the same job while hiding 6–8 inches of storage depth behind it. Modern medicine cabinets are far sleeker than the ones from 30 years ago — many have interior lighting, multiple adjustable shelves, and a frameless look that suits contemporary bathrooms.

If you're renovating anyway, this is an easy upgrade to include. If you're not renovating, it's a standalone project that can be done in a few hours.

6. Think Built-In, Not Added-On

The storage solutions that look best — and add the most home value — are ones that feel like part of the room, not things you bought and placed in it. Built-in linen towers beside the vanity, recessed shelving in unused wall space, and integrated cabinetry that matches your vanity all create a cohesive, intentional look.

When we do a full bathroom renovation, we always look for dead wall space — areas beside or above the toilet, between the vanity and the wall, or in awkward corners — that can be converted into built-in storage.

7. Declutter Before You Renovate

This one's free. Most homeowners are surprised how much more functional their bathroom feels after going through everything under the sink and in their cabinets. Expired products, duplicate items, and things that don't belong in the bathroom at all take up significant space.

A good rule: if you haven't used it in 60 days, it doesn't need prime bathroom real estate.

When Storage Ideas Aren't Enough: Renovation Might Be the Answer

If you've optimized what you have and your bathroom still doesn't work for your household, it may be time to look at a proper renovation. A well-planned bathroom reno doesn't just look better — it's designed around how you actually use the space, with storage built in from the start rather than added as an afterthought.

Common renovation upgrades that dramatically improve storage:

• Full vanity replacement with custom or semi-custom cabinetry
• Shower conversion with built-in niches and bench storage
• Recessed medicine cabinet installation
• Built-in linen tower addition
• Full bathroom redesign with storage as a priority
