The standard apartment bathroom is 5 by 8 feet. It has a tub with a shower curtain, a toilet, a pedestal or a 24-inch vanity with one drawer that does not close all the way, a mirror screwed straight to the wall, and one towel bar. There is a medicine cabinet if you are lucky, and a beige floor either way.

And you are not allowed to drill. Or you are, technically, but the lease says holes get patched at move-out and you know what the deposit deduction looks like.

Storage in a room this size is about surfaces that already exist and nobody uses. The wall above the toilet. The back of the door. The corner of the tub. The gap between the vanity and the wall. None of them need a screw, and together they hold more than a set of built-in shelves.

The wall over the toilet is your best square footage

Above a toilet tank there are 24 inches of wall by roughly 48 inches of height that never get used. A freestanding over-the-toilet unit stands on the floor behind the toilet, straddles the base, and gives you three shelves at $35-90.

Two measurements before you buy. The width of the tank, which the legs must clear (most units are 23 to 26 inches inside, and a lot of tanks are 18 to 20 inches, so you are usually fine). And the height from the floor to the bottom of the tank lid, so the first shelf sits at least 4 inches above the lid and you can still take it off.

Put the things you use daily on the lowest shelf in a basket, extra toilet paper on the middle, and something you like on top: a plant that tolerates humidity, a candle, a stack of towels in one color. The top shelf is the one you see from the door.

Tension rods do the work of a drill

A tension rod is a spring-loaded pole that holds itself between two walls. In a bathroom, three placements earn their $8-20 each.

Inside the tub, high on the wall opposite the showerhead, a rod holds S-hooks for a loofah, a razor and a hanging bottle caddy. Under the sink, a short rod across the cabinet holds spray bottles by their trigger heads and clears the cabinet floor for a bin. And a second shower curtain rod, mounted 6 inches inside the first, holds the liner on its own and gives you a bar to dry a towel or hang a plant.

Rods slip on glossy tile if the rubber ends are worn. Wipe the tile with rubbing alcohol before mounting and twist the rod until it is snug, then a half turn more.

Get the bottles off the tub ledge

A tub ledge covered in eleven bottles is what makes a bathroom look small. A corner caddy, either a tension pole ($25-60) that runs from the tub floor to the ceiling or a rustproof suction unit ($20-40), stacks all of them vertically in a corner and lets the curtain close over them.

Tension poles are the more reliable of the two. Suction cups on textured tile fail within a week. If you have a slick tile wall and want suction anyway, clean the tile, press the cup for a full 30 seconds, and give it 24 hours before loading it.

Set a rule for yourself: one shampoo, one conditioner, one body wash in the caddy at a time. Backups go in the over-toilet unit.

Use the back of the door

A bathroom door has 20 by 80 inches of surface that faces the room every time it is closed. An over-the-door rack with five or six hooks ($12-30) holds two bath towels, a hand towel and a robe. That replaces the single towel bar and gets wet towels spread out where they dry instead of folded over each other.

If the bracket on top keeps the door from closing, look for a rack with a flat, 2mm bracket, or shim the door stop. A towel hanging from a door hook also should not touch the floor; measure from the top of the door to about 30 inches down for a bath towel folded once.

Mirror cabinets, without the screws

A plain wall mirror wastes the space behind it. A shallow mirror cabinet, 4 inches deep, hides toothbrushes, a razor, medication and the contact lens stuff that turns a small vanity into a mess.

The honest problem is that almost all mirror cabinets ship with two or four screws. Two workarounds. First, if the existing mirror is screwed to the wall with clips, you can often remove it, hang the cabinet from the same holes and put the original mirror back at move-out. No new holes. Second, a cabinet under 10 pounds can hang from heavy-duty adhesive strips rated for 16 pounds or more, on a clean, painted, non-textured wall, after a 24-hour cure. It will not survive on tile.

If neither works for you, a freestanding vanity organizer with a mirror on top ($25-50) sits on the counter and does most of the same job.

Fix the floor and the walls without a landlord

Peel-and-stick vinyl tile ($20-50 per box of 10 to 20) covers a 5x8 floor with about 40 tiles, which is two or three boxes and an afternoon. Wash the old floor, let it dry, and start from the center so the cut tiles land under the vanity and behind the toilet. A utility knife and a straightedge are all the tools.

The caution: not every brand peels off clean. Stick one tile in a hidden corner, leave it two weeks, and pull it. If it leaves a sticky film, that brand is not for your rental.

For walls, a large washable bath mat in a rust, olive or navy covers the beige floor at the spot you look at most, and a matching hand towel and shower curtain make the room feel like a set rather than a collection. All of that runs $50-90, and every piece moves to the next apartment.

The five-minute version

If you only do three things: an over-toilet shelf, a corner caddy in the tub, and a hook rack on the door. About $80-150, no holes, and the counter and tub ledge are clear by dinner.

FAQ: How do I add storage to a small bathroom without drilling?

Use the surfaces already there. A freestanding over-toilet unit, a tension-pole caddy in the tub corner and an over-the-door hook rack add roughly 12 square feet of storage for $80-150 and leave no marks.

FAQ: Is peel-and-stick tile safe for a rental bathroom?

Sometimes. Some brands peel off cleanly after a year and some leave adhesive you will pay to remove. Test one tile in a hidden corner for two weeks before doing the floor, and keep the receipt.

FAQ: Where should towels go in a small bathroom?

On the back of the door. A rack with five or six hooks holds more than a towel bar, spreads towels out so they dry, and uses a surface that faces the room only when the door is closed.
