Swap the curtain before anything else

The shower curtain is the biggest piece of fabric in the room, so it sets the whole tone, and in most rentals it's a thin plastic panel doing all the damage. Swap it for a fabric one and the bathroom looks pulled together before you've spent a dollar on anything else. It's the single highest-impact change here, and it leaves with you. Go fabric over vinyl and the room stops reading like a rental.

A small bathroom almost never has floor space, but the wall above the toilet is sitting empty in nearly every one. A freestanding over-the-toilet shelf straddles the tank and gives you three tiers for towels, baskets, and the overflow that won't fit under the sink, no drilling required since it stands on its own legs. It's the most storage you can add to a tiny bathroom in one move. Style the top shelf and hide the boring stuff in a basket on the bottom.
Get the shower clutter off the tub edge

Five bottles balanced on the edge of the tub is what makes a shower feel chaotic, and it's usually because there's nowhere else to put them. A rustproof caddy that hangs off the showerhead or wedges in with a tension pole fixes it without a single hole in the tile. Look for rustproof coating, because the cheap wire ones leave orange streaks within months. Suddenly the tub edge is clear and the shower feels twice as calm.
Cover the floor you're not allowed to change

A dated or stained bathroom floor drags everything down, and you obviously can't retile a rental. Peel-and-stick vinyl tile is the loophole: it lays right over the old floor, comes in patterns that read like real cement or marble tile in photos, and lifts off when you leave. A graphic black-and-white or a soft terrazzo changes the entire feel of the room for the price of a couple of takeout dinners. Clean the floor first so it actually grips, and cut around the toilet base with a craft knife.
Stand on something that isn't a thin scrap of cotton

Rental bathrooms are cold tile and harsh light, and the standard-issue thin bath mat does nothing about either. A plush memory-foam mat is the cheapest comfort upgrade in the room, it's soft underfoot stepping out of the shower and it drops in a hit of warmth a tile floor badly needs. Get one with a non-slip backing, since wet tile is genuinely a fall risk. It's a small thing you notice every single morning.
Corral the vanity clutter onto one tray

A tiny vanity covered in loose bottles, tubes, and hair ties reads as mess even when everything's clean. Group the daily stuff onto a single tray and tuck the backups into a basket under the sink, and the same counter suddenly looks calm. A woven basket also hides the unglamorous overflow, the spare toilet rolls and the cleaning spray, in a way that reads styled instead of stashed. One container beats ten loose things every time.
Hide the dead space under the sink

The cabinet under the sink is usually a chaos of cleaning bottles, or if you've got a pedestal sink, it's awkward open space doing nothing. Either way, baskets are the fix: a couple of low bins corral the clutter in a vanity, and a simple tension-rod skirt around a pedestal sink hides a whole shelf of storage behind fabric. No tools, no commitment, and you reclaim the one bit of hidden space a small bathroom has.
Frame the builder mirror without taking it down

That frameless glued-on mirror is the most rental-looking thing in a lot of bathrooms, and prying it off is a deposit you'll never see again. Leave it up and frame it instead. Stick-on mirror trim presses right onto the glass edge and turns the plain rectangle into something that looks built in, or lean a separate framed mirror on the vanity in front of it if there's room. It's a ten-minute job that changes the focal point of the room.
Fix the light by changing one bulb

Bathroom lighting is almost always one cold, blue-white bulb over the mirror that makes everyone look exhausted. You don't need a new fixture to fix it, you need a warmer bulb. Swap in a soft white 2700K bulb and the whole room goes from clinical to flattering, tile and skin both. If the fixture takes a few, do them all so the light is even. It's the cheapest mood change in the bathroom and it takes thirty seconds.
Hang towels where there's no towel bar

Small bathrooms run out of towel space fast, and drilling a new bar into tile is exactly what you can't do. Adhesive hooks are the answer, the heavy-duty kind hold a wet bath towel fine, and a row of them on the back of the door or a bare stretch of wall adds hanging space anywhere. A hook also dries a towel faster than a folded one ever will. Press them onto a clean, dry surface and they peel off without a mark.
Add the one thing that likes a steamy room

Nothing softens hard tile and a mirror like something alive, and a bathroom's humidity is a gift to the right plant. A pothos trailing off the over-toilet shelf or a small eucalyptus hung in the shower thrives on the steam most rooms can't give it. No window? A snake plant handles low light without complaint. It's the smallest change on this list and somehow the one that makes the room feel cared for.
Match the small stuff so a cheap vanity reads expensive

A pile of mismatched plastic bottles is what makes a budget bathroom look budget. Decant hand soap and lotion into a couple of matching dispensers, and store cotton rounds and swabs in matching jars, and the whole vanity reads like you planned it. Amber glass or simple matte ceramic costs almost nothing and quietly does the work of a much pricier setup. It's the cheapest way to fake a designed bathroom.
Keep one surface clear and protect it

This is what keeps everything above from sliding back into clutter. Pick the bit of counter you actually use, usually right next to the sink, and keep it empty. Nothing lives there for good, not the makeup bag, not the phone, not the bottle that always creeps back. Once everything else has a home in a basket or on the shelf, that clear stretch stays clear, and in a small bathroom a clear surface is what reads as enough space instead of not enough.

The curtain is the easiest yes, so I ranked them.
