A small apartment bathroom under $100 makeover is the rental project most people put off forever, because the constraints look impossible: you cannot paint, you cannot retile, you cannot drill, and the landlord has explicitly said no to anything that requires a permit. The good news is that ninety percent of what makes a rental bathroom feel sad is removable in an afternoon, and the budget version costs less than dinner for two.
This guide walks through a real, end-to-end small apartment bathroom under $100 makeover for renters with a 30 to 50 square foot bathroom, builder-grade everything, and a security deposit they actually want back. Every item below is peel-and-stick, tension-mounted, hooked, or freestanding, and every dollar is accounted for so you can stop the makeover at any sub-total and still have a finished room.
Start with the audit, not the cart
Before you spend a dollar, stand in the doorway and write down four things: the bathroom width in inches, the wall behind the toilet (square footage), whether the floor is vinyl or tile, and whether the shower has a glass door or a curtain rod. Those four facts decide the entire makeover.
A typical rental bathroom is 5 by 7 feet (35 sq ft), has a 30 inch wide wall behind the toilet, vinyl click-lock or sheet flooring, and a tension shower rod with a builder curtain. If yours matches, the rest of this guide costs $87 to $98 depending on which curtain you pick. If you have a glass door instead of a curtain, swap the $24 curtain for a $20 etched window film and the budget drops to around $83.
The audit matters because the biggest waste in a small apartment bathroom under $100 makeover is buying the wrong size peel-and-stick wallpaper roll. Measure twice. A single roll covers about 20 square feet, and the wall behind the toilet is usually 14 to 18 square feet, so one roll handles the accent wall with margin.
The peel-and-stick wallpaper accent wall (under $40)
The single biggest visual change in a rental bathroom comes from putting one bold pattern on one wall. The wall behind the toilet is the obvious choice because it gets seen the moment anyone walks in and it is short, awkward, and currently doing nothing.
Peel-and-stick wallpaper at $30 to $38 per roll from Amazon, Target, or Spoonflower covers a 30 inch wide by 7 foot tall wall with a roll to spare. Look for patterns with a small repeat (4 to 8 inches) because a large repeat on a short wall wastes most of the roll matching the seams. Floral, blue-and-white delft, terracotta block print, and matte botanical patterns all photograph well in a small bathroom and date slowly.
Application is the hard part. Wash the wall with a damp cloth first (no soap, no primer, the adhesive needs clean drywall paint), let it dry an hour, and apply with a plastic credit card to push bubbles out from the center. Cut around the toilet tank, the outlet, and the trim with a fresh utility blade. Plan two hours for your first wall, one hour for the second if you ever do another.
At move-out, the paper peels off in 10 minutes and leaves zero residue if the original wall was painted with a satin or eggshell finish. If the wall is flat builder paint, test a small corner before committing. Total: $30 to $38.
The shower curtain swap (under $25)
The builder shower curtain that came with the apartment is doing more damage to the room than any other single item. It is plastic, it is white, it is 70 inches long, and it ends six inches above the floor like a too-short pair of pants. Replace it with a fabric curtain that is 84 to 96 inches long and the bathroom suddenly looks intentional.
Target Threshold, H and M Home, and IKEA all sell 84 inch fabric shower curtains for $20 to $24 in neutral linen, waffle weave, or simple stripes. Pair the fabric curtain with a $5 clear plastic liner behind it (Amazon Basics) and you get the long-curtain look without water damage. The clear liner is invisible from the front and replaces the awful translucent builder version.
Hang the curtain as high as the existing rod allows. If the rod is already at standard height (about 6 feet up), the 84 inch curtain pools by an inch on the floor, which reads as upgraded. Use the existing tension rod (no new hardware) and the swap takes ten minutes. Total: $24 to $29.
Two floating shelves above the toilet (under $20)
The 18 inches of wall above a toilet tank is the most underused vertical space in any rental bathroom. A pair of stick-on floating shelves (Command brand, $9 per shelf, rated to 5 pounds each) installs in five minutes with no drilling and holds rolled towels, a small plant, a candle, and the extra roll of toilet paper that has been living on the back of the toilet.
For a more solid look, the IKEA Lack wall shelf at $10 each technically requires screws, but the included plastic anchors leave a hole roughly the size of a pin. Use a small bit of white toothpaste at move-out and the wall is invisible. Two Lacks at 11 inches deep by 23 inches wide give you 506 square inches of new storage in a room that previously had a single cluttered counter.
Style the shelves with a hard 3-item rule per shelf: one tall thing (eucalyptus stems in a small vase, $6 from Trader Joe’s), one short stack (3 rolled hand towels or 2 books), one round thing (a candle, a bowl, or a small terracotta pot). The rule prevents shelf clutter and gives the styling a designed look. Total: $18 to $20.
One plant the bathroom can actually keep alive
The plant rule for windowless or low-light rental bathrooms is short: pothos, snake plant, or ZZ plant, and nothing else. All three tolerate 80 percent humidity, weeks of neglect, and the artificial light that comes from leaving the bathroom door open for a couple of hours a day. A 4 inch pothos from Home Depot is $6, a 6 inch is $14.
For renters whose bathroom has zero natural light, a faux pothos from Target ($12) looks real from 3 feet away in the kind of light a bathroom has anyway. It does not water, does not die, and lasts the length of the lease. Set it on the top floating shelf, let one vine trail down, and the room reads as cared for.
If you have one window, even frosted glass, a snake plant on the windowsill is the right call. They grow vertical, hold their shape, and add height in a room where everything else is horizontal. Total: $6 to $14.
Bath mat and hand towel set (under $20)
The builder bath mat that came with your apartment is a thin rubber-backed rectangle in a color nobody chose. Replace it with a tufted cotton bath mat in a single color (Target Casaluna, $15) and the floor reads as styled instead of utility. Avoid patterns on the bath mat because there is already a pattern on the wallpaper accent wall and a stripe or weave on the shower curtain. The floor should be calm.
Hand towels are the cheapest single upgrade in a small apartment bathroom under $100 makeover. A pair of waffle weave hand towels in a coordinating color is $8 from H and M Home or $12 from Target. Hang them on the existing towel ring or, if you do not have one, on a $5 over-the-door hook. Two hand towels, one folded on the vanity and one hanging, doubles the soft texture in the room. Total: $15 to $20.
Storage upgrades that are not floating shelves
If the shelves above the toilet are full and you still have clutter on the counter, you need a second storage move. The cheapest is a $12 tiered organizer that sits on the counter and holds the daily skincare, perfume, or grooming items vertically. A $15 over-the-door pocket organizer (the kind sold for shoes, but used for bathroom supplies) handles the rest.
For renters with a pedestal sink and no vanity, a $20 freestanding under-sink basket cabinet from Amazon (the kind that wraps around the pedestal) adds 2 cubic feet of hidden storage that was previously a dust trap. It is the single highest-impact $20 in a pedestal-sink bathroom. If you have a vanity already, skip this and use the $20 on a better mirror instead.
The wire grid panel hanging on the wall (the Pinterest pegboard look) is a $14 Amazon item that works as a renter-friendly bulletin board, jewelry organizer, or makeup hook station. Hang it from two Command Outdoor Light Clips (rated to 5 pounds each), and the whole grid comes down in 30 seconds at move-out. Total of these add-ons: $20 to $40 depending on which you pick.
Lighting and mirror (under $30 if you keep the existing fixture)
Replacing the builder vanity light requires an electrician or at least an afternoon of YouTube, and most renters cannot do it. Skip the fixture and change two things instead: the bulb temperature and the mirror.
Swap the cool fluorescent or daylight bulb in your vanity light for a soft white LED at 2700K (Philips, $4 each, two pack at Home Depot). The single $8 bulb swap is the most underrated upgrade in any rental and changes how the entire room photographs. Skin tone reads better, the wallpaper reads warmer, and the bathroom feels less like a hospital.
The mirror is harder. If you have a builder-grade flat sheet mirror, leave it but lean a $20 round black-framed mirror (Target Threshold) on a shelf or on the back of the toilet tank, in front of the flat mirror. The layered look hides the original mirror’s lack of frame and reads as styled. If your mirror has a frame already, swap the frame color with peel-and-stick black trim tape (Amazon, $9) and call it done. Total: $8 to $30.
The full budget breakdown for the small apartment bathroom under $100 makeover
Tallying the makeover at the entry-level version: $30 wallpaper, $24 curtain plus $5 liner, $18 two floating shelves, $6 plant, $15 bath mat, $8 hand towels, $8 bulb swap, $0 mirror (use what you have). Total: $114. To bring it under $100, skip the floating shelves ($96) or skip the bath mat and use the existing one for another month ($99).
The premium under-$100 version (sacrificing one element to upgrade another): $35 better wallpaper, $24 curtain plus $5 liner, $9 one floating shelf, $12 faux plant, $15 bath mat, no new hand towels for now, $8 bulb swap. Total: $108, or $98 if you keep the existing bath mat.
The truly minimal version that still transforms the room: $30 wallpaper, $24 curtain plus $5 liner, $6 plant, $8 bulb swap. Total: $73. The wallpaper does the heaviest lifting, the curtain dresses the room, the bulb warms the light, and the plant signals care. Even at $73, the bathroom looks like a different room.
What to do in what order on the makeover weekend
The order matters because dust falls and water gets everywhere. Friday night: take everything off the counter and the back of the toilet, throw out the builder bath mat, and wash the accent wall with a damp cloth. Let the wall dry overnight.
Saturday morning: apply the peel-and-stick wallpaper before you do anything else, because it is the messiest step and the room needs to be empty. Plan two hours. After the wall is done, vacuum the floor (the wallpaper trim creates a lot of paper bits) and put the new bath mat down.
Saturday afternoon: hang the new shower curtain, swap the bulb, install the floating shelves, place the plant, and style the shelves. The whole afternoon segment is about three hours including a coffee break. By Saturday evening you are looking at a finished room and a small pile of packaging.
Move-out reversal checklist
The whole reason this small apartment bathroom under $100 makeover works is that it comes apart in an hour. At move-out: peel the wallpaper off the wall (start at a top corner, pull slowly at a 30 degree angle), unhook the curtain, pull the floating shelves off the wall (Command strips release with a slow downward pull), swap the bulb back to whatever was there originally, and recycle the bath mat.
If the wallpaper leaves any adhesive residue, a microfiber cloth with a tiny bit of warm soapy water removes it. If the Command shelves leave a faint outline, white toothpaste rubbed in a circle and wiped off handles it. The whole reversal is under 60 minutes and uses items already in your kitchen.
Take photos before you start the makeover and again after the reversal, because some landlords will try to charge for normal wear and tear. A timestamped photo of the wall before and the wall after move-out reversal protects the security deposit. The makeover paid for itself the first time you took a Sunday morning bath in a bathroom that did not depress you, and the deposit comes back intact.
The takeaway
A small apartment bathroom under $100 makeover is one of the highest-return renter projects, because the room is small enough that every change is visible and the original is bad enough that any thoughtful change looks dramatic. Pick the wallpaper first, swap the curtain second, change the bulb third, and the bathroom is already 70 percent of the way to a magazine photo.
Skip the shelves and the plant if budget is tight; they are nice-to-haves, not need-to-haves. Skip the wallpaper if your landlord is the kind of person who will inspect every wall at move-out, and put the saved $30 toward a real glass-framed mirror and a better lighting fixture you can take with you. The bones of the bathroom do not move, the budget never goes above $100, and the deposit stays intact.
The bathroom is the room people apologize for during the apartment tour, and it does not need to be. A weekend, $73 to $98, and three trips to Target and the hardware store turns the worst room in any rental into the one your friends ask about. Renters do not get to renovate, but they do get to redecorate, and a small apartment bathroom under $100 makeover is the proof.
