My guest bathroom is 40 square feet. There’s barely room to turn around. When my mother-in-law visits for a week, she needs space for her toiletries, towels, and the surprising amount of stuff Boomer women travel with. I’ve spent the last year testing every small-bathroom storage idea on Pinterest, and 15 of them actually work.
Here they are, with real prices.
1. Over-toilet etagere shelving ($65)
The single highest-impact addition to a small bathroom. A 3-tier wood etagere from Target or Wayfair fits over the toilet tank, uses vertical space that’s otherwise wasted, and provides storage for towels, baskets, decor. Mine holds 3 woven baskets stuffed with extra TP, shampoo refills, and guest toiletries.
2. Lazy Susan inside cabinets ($14)
The under-sink cabinet is a black hole where bottles fall over and roll to the back. A 10-inch lazy Susan from the Container Store puts every bottle within arm’s reach. I use two – one for hair products, one for cleaning supplies.
3. Magnetic strip for metal tools ($8)
A 12″ magnetic knife strip mounted inside the medicine cabinet holds bobby pins, tweezers, nail clippers, hair clips, scissors. Frees up an entire drawer. Just don’t mount it where it’ll catch the sleeve of your robe.
4. Tension rod under the sink ($6)
Mount a tension rod across the cabinet under the sink, hang spray bottles by their trigger handles. Doubles your under-sink storage and prevents the chaos of bottles falling over. Works in any cabinet that’s 18-30 inches wide.
5. Suction-cup shower caddy ($12)
The classic OXO suction caddy holds shampoo, conditioner, and body wash on the shower wall – no drilling, no rust like wire caddies. Replace every 2-3 years when the suction weakens.
6. Shower curtain with pockets ($18)
The mDesign shower curtain has 8-12 mesh pockets on the inside. Holds soap, razors, washcloths, kid bath toys. Genius if you don’t have built-in shower shelves.
7. Wall-mounted towel ladder ($45)
Leans against the wall, holds 4-5 towels, looks intentional. Doesn’t require drilling unless you want to anchor it. IKEA, Wayfair, and West Elm all sell these in wood or metal.
8. Pegboard on the back wall ($32)
An IKEA SKADIS pegboard (24×36″) mounted behind the door holds hair tools, towels, baskets – whatever you can hang. Customizable, removable, no permanent damage if you use Command strips on small walls.
9. Drawer dividers (bamboo, $16)
Bathroom drawers get chaotic fast. Bamboo drawer dividers from Amazon sort makeup, hair ties, lotions into compartments. The expandable kind fits any drawer size and stays put.
10. Wall-mounted toothbrush cup holders ($14)
Removes 3 things from your countertop: toothbrush holder, toothpaste cup, and the soggy spot underneath. Drill into the wall above the sink. Made of brushed nickel for $14 at Target.
11. Behind-the-door wire rack ($28)
An over-the-door wire organizer holds 6+ items in the space behind your bathroom door. Hair products, robes, towels, baskets. The wire ones are stronger than the plastic, but cover with felt strips so they don’t scratch the door.
12. Decorative basket on toilet tank ($12)
A small woven basket on the toilet tank holds a guest hand towel and a small soap. Looks intentional, not crowded. Don’t pile junk into it; one or two items only.
13. Magnetic mirror medicine cabinet ($75)
If you’re replacing a builder-grade medicine cabinet, look for one with magnetic strips, adjustable shelves, and outlets inside (for storing charging electric toothbrushes hidden). IKEA’s GODMORGON line is $75-150 depending on size.
14. Corner shower shelf ($22)
A stainless steel corner caddy that mounts with strong adhesive (no drilling into tile). Fits in the empty corner of any shower. Three tiers hold shampoo, conditioner, body wash, plus razors and a soap dish.
15. Wall-mounted hairdryer holder ($16)
Hairdryers don’t have a natural home. A wall-mounted holster next to your vanity (or inside the cabinet door) keeps it accessible without taking drawer space. Available at Bed Bath & Beyond and Amazon.

Frequently Asked Questions
What’s the single best storage upgrade for a small bathroom?
An over-toilet etagere. It uses dead vertical space, holds 3-4 baskets of stuff, and visually elevates the bathroom. $65 at Target. Single highest-impact change you can make.
How do I add storage without drilling holes?
Tension rods, suction caddies, magnetic strips with adhesive backs, Command hooks, over-the-door racks, freestanding etageres. Renters can build a fully-functional bathroom storage system with zero drilling.
How do I declutter a bathroom?
Start with expired products – sunscreen, medications, makeup. Most have shelf lives of 6 months to 2 years. Then duplicates (do you need 4 conditioners?). Then “what if I need it” items you haven’t touched in a year. See my things to throw away list.
What’s the worst storage choice for bathrooms?
Wire baskets. They rust, snag on towels, and look industrial. Use woven seagrass or fabric bins instead. Also avoid open shelving for medications – guests will see them.
