My bathroom in my Toronto rental is 38 square feet. That is not a typo. There is a toilet, a pedestal sink with zero storage underneath, a shower stall, and about 60 cm of floor space between them. When I moved in, my toiletries lived on the toilet tank and the edge of the sink. Within three months I had figured out a system that actually works — no drilling required, all from Canadian retailers, under $180 CAD total for the core setup. Here is that system, in the order that makes the most difference.
TL;DR:
- First move: freestanding over-toilet shelves (~$55–$70 CAD, Amazon.ca) — adds three shelves of vertical storage instantly, no drilling
- Second move: over-door organizer on the bathroom door (~$20–$35 CAD) — holds toiletries, hair tools, cleaning supplies
- Under $180 CAD total covers the four most impactful changes for most Canadian rental bathrooms
- All solutions on this list work in Toronto, Vancouver, and Calgary rental apartments — no permanent wall changes required
1. Over-Toilet Shelving — The Highest-Value Move
In a small bathroom, the wall above the toilet is the only large open vertical zone. Most small rental bathrooms waste it entirely.
A freestanding over-toilet shelf unit sits around the toilet tank and adds three full shelves of vertical space without touching the walls. The Songmics 3-tier unit on Amazon.ca runs ~$55–$70 CAD and fits standard Canadian toilet dimensions. Three shelves hold toiletries, extra toilet paper rolls, small baskets, and hand towels with room to spare.
Why this is first: It’s the single largest storage gain per dollar available in a small bathroom. Three shelves of vertical space for ~$60 CAD, installed in 10 minutes, removed in 5.
Options:
- Songmics 3-tier over-toilet shelf (~$55–$70 CAD, Amazon.ca) — bamboo or metal, adjustable height
- IKEA VESKEN corner shelf unit (~$20 CAD) — compact, works beside or behind a toilet in corner configurations
- HomeSense over-toilet unit (~$50–$80 CAD) — check the home storage section, stock varies by location
What to put on the shelves: Decorative baskets on the top shelf (they hide clutter and look intentional), rolled towels on the middle shelf, daily toiletries on the bottom shelf within easy reach.
2. Over-Door Organizers — The Most Underused Space
The back of the bathroom door is typically empty in Canadian rental bathrooms. An over-door organizer converts that vertical surface into usable storage with zero wall damage.
A clear pocket over-door organizer (24 pockets, ~$20–$30 CAD on Amazon.ca) holds shampoo, conditioner, body wash, razors, cotton balls, and small accessories in full view. You can see everything without opening a drawer.
Options by category:
For toiletries:
- Clear pocket organizer, 24-pocket (~$20–$30 CAD, Amazon.ca) — best for small bottles and daily products
For hair tools and larger items:
- Over-door hook rack with shelves (~$30–$45 CAD, Amazon.ca or Canadian Tire) — holds a hair dryer, straightener, and accessories on hooks, plus one or two shelves for baskets
For cleaning supplies:
- Over-door 3-tier basket organizer (~$25–$35 CAD, Amazon.ca) — keeps cleaning sprays and supplies out of the under-sink cabinet and easily accessible
Installation note: Check that the organizer fits your specific door. Most Canadian interior bathroom doors are 198 cm tall and 81 cm wide. Standard over-door hooks fit doors up to 4 cm thick — measure your door frame before ordering.
3. Medicine Cabinet Upgrade
The medicine cabinet is the most efficient storage unit in the bathroom per square centimetre of wall space. Most builder-grade cabinets in Canadian rental apartments are shallow (8–10 cm deep) and have two or three shelves. A replacement adds usable depth and shelf count.
Surface-mounted vs. recessed:
- Surface-mounted (attached to the wall surface with screws): fine to swap in a rental. Remove the old one, install the new one, patch four screw holes with renter-safe filler when you leave.
- Recessed (built into the wall): leave it. Do not open the wall in a rental apartment.
Options:
- Kohler Verdera surface-mount cabinet (~$150–$200 CAD at Home Depot Canada) — 38 cm × 71 cm, mirrored exterior, four adjustable shelves inside, 13 cm deep
- IKEA GODMORGON wall cabinet (~$80–$120 CAD) — surface-mount, soft-close hinges, 40 cm × 58 cm, two interior shelves
- Amazon.ca surface-mount options (~$60–$120 CAD) — wide range, search “surface mount medicine cabinet Canada”
The mirror exterior also eliminates the need for a separate bathroom mirror, freeing wall space for other uses.
4. Under-Sink Organization
A pedestal sink has no under-sink storage at all. A vanity cabinet has under-sink space, but it is usually a single open cavity with a pipe running through the middle — disorganized by design.
Two approaches, depending on your sink type:
If you have a pedestal sink:
- A slim rolling cart (IKEA RÅSKOG, ~$30 CAD) parked beside or behind the pedestal holds far more than you’d expect. Three tiers, 35 cm × 28 cm footprint, rolls out when you need it.
- Alternatively, a freestanding bathroom storage cabinet (~$80–$130 CAD, Amazon.ca or HomeSense) positioned next to the pedestal replaces the missing vanity storage.
If you have a vanity cabinet:
- A tension rod installed across the interior (~$10–$15 CAD, Canadian Tire) lets you hang spray bottles from their trigger handles — clears the entire floor of the cabinet for bins and baskets
- Two pull-out cabinet organizers (~$18–$25 CAD each, Amazon.ca) on each side of the pipe maximize the usable floor space of the cabinet
- A small turntable (lazy Susan, ~$12–$18 CAD, Amazon.ca) in the corner lets you access items at the back without unloading everything in front
Total under-sink upgrade cost: ~$30–$60 CAD depending on your sink type.
5. Shower and Bath Storage
Shower storage in a small apartment bathroom almost always means a tension shower caddy — a caddy held in place by a tension pole that runs from floor to ceiling.
Why tension over suction cups: Suction cup caddies fall off ceramic tile, especially in humid conditions. Tension caddies don’t. They hold 10–15 kg, adjust to any ceiling height, and leave no marks when removed.
Options:
- Zenna Home tension shower caddy (~$45–$65 CAD, Amazon.ca) — 4-tier, adjustable, chrome or matte black finish
- InterDesign tension caddy (~$35–$50 CAD, Amazon.ca or Canadian Tire) — 3-tier, good for a single person’s products
- IKEA BROGRUND (~$15 CAD) — basic hanging caddy for the shower head rod, works if you have limited products
For bathtub renters: A tub caddy that rests across the tub edges (~$25–$60 CAD, Amazon.ca) holds soap, shampoo, a razor, and a small candle without any installation. Expandable versions fit tubs from 66 cm to 90 cm wide.
6. Counter Declutter — Keep Only Daily Items
Counter space in a small bathroom is the most valuable surface area you have. Every item left on the counter permanently reduces your functional workspace and makes the bathroom feel smaller.
The rule: only items used every single day live on the counter. Everything else gets a home off the counter.
Counter organization tools:
- A small tray or catchall dish keeps daily items (soap, toothbrush holder, face wash) organized in one zone rather than scattered (~$10–$20 CAD, HomeSense)
- A wall-mounted toothbrush holder with suction cup base (~$12–$18 CAD, Amazon.ca) moves two items off the counter entirely
- A slim countertop organizer with two tiers (~$20–$30 CAD, Amazon.ca) doubles the counter space by using vertical height
What moves off the counter permanently: extra makeup, cotton balls, hair accessories, backup products. These belong in the over-door organizer, medicine cabinet, or a drawer organizer.
7. Towel Storage Without a Towel Bar
Most small Canadian rental bathrooms have one towel bar. That is rarely enough for more than one person, and towel bars require drilling if you want to add more. Three renter-friendly alternatives:
Option 1: Over-door towel hooks An over-door hook rack on the bathroom door holds four to six towels without any wall contact. The OXO Good Grips 4-hook over-door rack (~$35–$45 CAD, Amazon.ca) fits doors up to 3.8 cm thick.
Option 2: Freestanding towel rack A freestanding ladder-style towel rack (~$30–$60 CAD, Amazon.ca or HomeSense) leans against the wall and holds three to four towels. No installation. Moves with you. Takes about 30 cm of floor space.
Option 3: Command hook strips for hand towels Command large hook strips (rated 2–3 kg each) hold hand towels on any wall surface, including painted drywall. A 4-pack is ~$12 CAD at Canadian Tire or Walmart Canada. Remove cleanly when you leave with no wall damage.
8. Renter Rules — The No-Drill Framework
Canadian standard residential tenancy agreements in Ontario, BC, and Alberta all include clauses about alterations to the unit. The practical line for bathroom storage:
Generally fine without landlord permission:
- Freestanding furniture (over-toilet shelves, rolling carts, ladder racks)
- Over-door organizers and hooks
- Tension rods (inside cabinets or shower)
- Command strips and hooks (removed properly per manufacturer instructions)
- Swapping a surface-mounted medicine cabinet (patch screw holes before moving out)
Requires landlord permission or should be avoided:
- Drilling new holes in tile (grout and tile damage is expensive to repair)
- Adding new towel bars to walls
- Replacing a recessed medicine cabinet
- Altering any plumbing connections
The practical test: If you can take it with you when you move and leave the bathroom in identical condition, it’s a no-drill solution. This covers 90% of the storage changes on this list.
The Bathroom Storage Priority Order
| Step | Action | Cost (CAD) |
|---|---|---|
| 1 | Freestanding over-toilet shelf unit | ~$55–$70 |
| 2 | Over-door pocket organizer (24-pocket) | ~$20–$30 |
| 3 | Tension shower caddy | ~$35–$65 |
| 4 | Under-sink tension rod + pull-out bins | ~$28–$40 |
| 5 | Freestanding towel rack or over-door hook rack | ~$30–$45 |
| Total steps 1–5 | ~$168–$250 |
Complete steps 1 through 3 before spending on anything else. These three changes handle 80% of bathroom storage problems in a small Canadian apartment. Steps 4 and 5 are refinements.
Bathroom Storage for Two in a Small Apartment
Two people sharing a small apartment bathroom doubles the product count and the friction. Three changes make the biggest difference:
Divide the medicine cabinet by shelf. Each person gets one to two shelves, clearly assigned. No mixing. No searching through someone else’s products to find your own.
Separate over-door organizer sections. Label two columns of the pocket organizer per person or use two different organizers on separate hooks. Each person’s daily products stay in their column.
A rolling IKEA RÅSKOG cart per person. Two RÅSKOG carts (~$30 CAD each) parked side by side under a pedestal sink or beside the toilet give each person their own portable storage unit. Total cost: ~$60 CAD. Total problem solved: most of the storage arguments in a shared small bathroom.
Complete steps 1 through 3 of the priority order before purchasing anything else. The over-toilet shelf alone typically solves 50% of the clutter problem in a small Canadian apartment bathroom.
