The bathroom is the smallest room in the house and somehow holds the most stuff: half-used bottles, three hair dryers, a first-aid kit from 2014 and a stack of towels that never quite fits. Most "organization" attempts fail because they start by buying bins. The system that works starts with removing what does not belong, then assigning every remaining item a zone based on how often you use it, and only then buying the two or three organizers that zone actually needs. This guide walks through the vanity cabinet, drawers, medicine cabinet, shower and the wall, with specific solutions for tiny bathrooms and a look at which vanities are built for storage.
Key takeaways
- Empty everything first. Toss expired, duplicate and unused products. Most people remove a third of what was in the bathroom.
- Sort by frequency: daily items at eye level or in the top drawer, weekly under the sink, rarely used up high or out of the bathroom.
- Under-sink cabinets waste 60% of their volume around the P-trap. A two-tier sliding organizer or stackable bins fix it.
- Drawers beat doors. If you are replacing the vanity, choose one with full-extension drawers.
- A medicine cabinet adds 15–30 litres of eye-level storage in the space a mirror already occupies.
- Group like items in labelled containers and do a five-minute reset weekly.
Step 1: Take everything out
Set a timer for 30 minutes. Clear the vanity top, the cabinet, every drawer, the medicine cabinet and the shower shelf onto a towel on the bed or the floor. You cannot organize what you cannot see, and this step alone usually reveals four bottles of the same shampoo.
Wipe every surface while it is empty. Cabinet floors under the sink are often damp; if the particleboard is swollen, that is a sign of a slow leak and worth checking the trap connections (our bathroom sink guide shows the P-trap).
Step 2: Declutter with four piles
| Pile | What goes here | What to do with it |
|---|---|---|
| Toss | Expired medication and sunscreen, mascara older than 3 months, dried nail polish, razors past their prime, anything you have not used in a year | Medication goes back to a pharmacy (all Ontario pharmacies take it), not the toilet |
| Relocate | Bulk toilet paper, backup toiletries, cleaning supplies for other rooms, the guest towels, the humidifier | Linen closet, laundry room, under-bed bin |
| Consolidate | Three half-empty bottles of the same thing, sample sizes, travel kits | Combine, finish, or make one travel bag and stop |
| Keep | Everything you actually use in this room | Sort into daily / weekly / occasional before putting anything back |
Step 3: Assign zones by frequency
Daily (reach without bending)
Toothbrush, toothpaste, face wash, moisturizer, deodorant, razor, daily makeup, contact lens case. Location: top drawer, medicine cabinet, or a small tray on the counter.
Weekly
Hair dryer and styling tools, nail kit, masks, extra shampoo, bathroom cleaner, feminine products. Location: under the sink in bins, or the second drawer.
Occasional
First-aid kit, travel bag, hair clippers, spare toothbrush heads, guest amenities. Location: top shelf of a wall cabinet, the back of the under-sink cabinet, or the linen closet.
Step 4: Organize the under-sink cabinet
The cabinet under the sink is deep, tall and interrupted by the P-trap and supply lines. Left alone, things pile up at the front and the back is lost. The fix is to build levels.
- Measure first. Width, depth and, critically, the height from the cabinet floor to the bottom of the trap. Note where the trap sits (usually centre-back).
- Add a two-tier sliding organizer ($25–$60) that straddles the pipes. The lower tray holds cleaning supplies; the upper tray holds daily-weekly items and pulls out so you can see everything.
- Use clear stackable bins for categories: hair, skincare backups, cleaning, first aid. Label them; even you will forget which is which.
- Add a tension rod near the top, front to back, to hang spray bottles by their triggers. It clears a whole shelf.
- Use the door. An over-the-door rack or adhesive hooks hold the hair dryer, a cloth and the toilet brush caddy.
- Put a mat down. A cut-to-size rubber or silicone liner protects the cabinet floor from the inevitable drip and makes cleaning easy.
Step 5: Organize the drawers
- Top drawer = daily zone. Use adjustable acrylic or bamboo dividers so toothbrushes, razors and small tubes each have a slot. Nothing should be stacked.
- Second drawer = tools. A drawer with a built-in outlet or a docking insert for the hair dryer and flat iron is the single best upgrade for a shared bathroom. If your vanity has no outlet, a drawer-mounted heat-resistant silicone holder works.
- Deep drawers hold bottles upright. Add a small bin or two to stop them sliding.
- U-shaped drawers (cut around the sink) are wide and shallow. Use them for flat items: makeup palettes, brushes, hair ties.
- Line drawers with a washable liner. Toothpaste and foundation will get on it eventually.
Step 6: Use the medicine cabinet properly
A recessed or surface-mount medicine cabinet is the most under-used storage in the bathroom. It sits at eye level, keeps things off the counter and closes so the room looks tidy. The modern ones are also the mirror, so nothing is lost.
- Top shelf: items you use least (nail kit, spare razor blades).
- Middle shelves: daily skincare, deodorant, toothpaste. Arrange tallest at the back.
- Bottom shelf: toothbrushes in a small cup, contact lenses, the things you grab half-asleep.
- Inside the door: adhesive magnetic strips hold tweezers, nail clippers and bobby pins; a small adhesive cup holds cotton swabs.
- Choose a cabinet with adjustable glass shelves, an internal outlet for an electric toothbrush, and LED lighting with a defogger so it doubles as the vanity light.
Step 7: Tame the counter
The counter is not storage. Keep it to a soap dispenser and one tray with the two or three items you use every single day. Everything else goes into a zone. A small tray makes even three items look intentional, and lifting one tray to wipe the counter takes ten seconds.
Step 8: The shower and the wall
- Shower niche or corner shelf: one bottle per person per category. Decant into matching pump bottles if you want it to look like a hotel; skip it if you will not keep up with refilling.
- Tension shower caddy or adhesive shelves for rentals where you cannot drill.
- Over-the-toilet shelving: 20–30 cm deep, holds towels and a basket of backups. The vertical space above the toilet is usually empty.
- Hooks instead of a towel bar. Four hooks hold four towels in the wall space of one bar, and towels dry faster on hooks.
- Rolling cart in the gap between the vanity and the wall for a bathroom with no drawers.
Small bathroom storage ideas
| Problem | Solution | Approx. cost |
|---|---|---|
| Pedestal sink, no storage at all | Replace with a 24" vanity with drawers, add a medicine cabinet | $150–$500 + cabinet |
| Vanity has a door, no drawers | Two-tier pull-out organizer + door rack | $40–$80 |
| No linen closet | Over-toilet shelf or tall narrow cabinet; roll towels | $60–$200 |
| Plain mirror, no cabinet | Swap for an LED medicine cabinet the same size | $300–$450 |
| Two people, one small vanity | One drawer or bin each; shared items in the cabinet | $0 |
| Kids' bath chaos | Mesh bag for tub toys on a suction hook; one caddy per child | $15–$30 |
Choosing a vanity that is built for storage
If you are replacing the vanity, storage should be the first thing you look at, not the last. What matters:
- Drawers over doors. A 30" vanity with three drawers holds more usable storage than a 36" vanity with two doors, because nothing gets lost at the back.
- Full-extension, soft-close slides. Full extension means you see the whole drawer. Soft-close means it lasts.
- A U-shaped top drawer that wraps around the plumbing rather than a fake drawer front.
- Solid wood or HDF cabinet rather than particleboard, which swells at the first leak.
- Double-sink vanities (60"+) should have drawers in the centre stack, not just doors under each sink.
- Height: 34"–36" comfort height gives deeper drawers than the old 30"–32" standard. Our vanity height and sizes guide covers this in detail.
Keeping it organized: the weekly reset
- Five minutes, once a week (Sunday evening works): put strays back in their zone, wipe the tray, check the bin of backups.
- One in, one out. A new shampoo means the old bottle is finished or tossed.
- Shop the backups first. Before buying, check the "backup" bin. This is where the duplicates come from.
- Seasonal edit, twice a year. Repeat Step 2 in 20 minutes. Sunscreen and cold medicine expire; makeup ages.
- Label everything that lives in a bin. Labels are how the system survives other people.

Frequently asked questions
How do I organize under a bathroom sink with pipes in the way?
Measure the clear height under the trap, then use a two-tier sliding organizer that straddles the pipes, stackable clear bins for categories and a tension rod to hang spray bottles. The goal is to create levels so the back of the cabinet is usable.
What should I keep on the bathroom counter?
As little as possible: a soap dispenser and one small tray with two or three daily items. Everything else belongs in a drawer, the cabinet or the medicine cabinet.
Is a medicine cabinet worth it?
Yes, especially in small bathrooms. It adds eye-level storage in the space a mirror already uses, hides clutter behind a door, and modern LED models double as the vanity light with a defogger.
Where should I store medication if not the bathroom?
A cool, dry cupboard in the bedroom or kitchen, out of reach of children. Bathroom heat and humidity shorten the life of most medication.
Drawers or doors on a bathroom vanity?
Drawers. Full-extension drawers let you see and reach everything; cabinets with doors lose the back third to clutter. If you must have a door cabinet, add a pull-out organizer.
How often should I declutter the bathroom?
A five-minute reset weekly and a full edit twice a year. Products expire faster than people expect: sunscreen in a year, mascara in three months, opened skincare in 6–12 months.
