That sliver of floor next to the toilet is easy to ignore, but the right narrow bathroom storage beside toilet piece can hold spare rolls, cleaners, wipes, and daily supplies in a spot that is now wasted. The trick is width. Every piece on this list is made to fit a gap of about 6 inches, not a wide-open wall.
Measure before you buy. Typical toilet side gaps are 6 to 9 inches, but baseboards, supply lines, and the curve of the bowl can steal an inch at floor level. Measure at the floor, at mid-height, and at the widest point of the bowl, then use the smallest number. For a true 6-inch gap, choose pieces that are 6 inches wide or less, and leave a little room so you can slide them out to clean.
For Daily Supplies You Reach for Every Day
1. Slim 3-tier rolling cart. Best for daily supplies like wipes, cotton pads, and a spare roll, this cart is usually about 5.5 inches wide, 15 to 17 inches deep, and 26 inches tall, so it rolls out when you need it and tucks back after. Small wheels can catch on grout lines and bath mats. Typically $18–$30.
2. Slim 4-tier rolling cart. Best for taller routines, with an extra tier for hair products, lotion, and cleaning spray in a frame still around 5.7 inches wide and 30 to 34 inches tall. The taller frame feels less steady when the top tier holds heavy bottles, so keep weight low. Typically $22–$38.
3. Standing toilet paper holder with a reserve post. Best for keeping three or four spare rolls upright in almost no floor space, most are about 6 inches wide at the base and 20 to 24 inches tall, with the roll in use on top. It holds rolls only, so it will not solve clutter on the tank or floor. Typically $16–$28.
For Spare Rolls, Cleaners, and Overflow
4. Narrow étagère tower. Best for a neat stack of spare towels, rolls, and a small plant or basket, this open shelf unit is usually about 5.9 inches wide, 12 to 14 inches deep, and 28 to 36 inches tall. Open shelves show everything, so dusty or mismatched items will look messy. Typically $30–$55.
5. Slim lidded basket tower. Best for hiding spare rolls and feminine supplies behind a softer look, with two or three stacked baskets in a footprint about 6 inches wide and 12 inches deep. Baskets hold less than solid shelves, and natural fibers can hold bathroom moisture if the room stays steamy. Typically $20–$35.
6. Standing holder with a closed storage box. Best for spare rolls plus wipes or a phone, this type pairs a top dispenser with a small box base about 5.5 to 6 inches wide and 18 to 22 inches tall. The box is small, so bulky refill packs will not fit inside. Typically $18–$32.
For a Closed Look That Hides the Clutter
7. Slim cabinet with one door. Best for cleaners and personal items you want fully hidden, a narrow cabinet is usually about 6 inches wide, 13 to 16 inches deep, and 24 to 32 inches tall, with two shelves inside. The door needs swing room, which can be tight if the vanity sits close on the other side. Typically $40–$70.
8. Slim 2-drawer unit. Best for small items that roll around on open shelves, like cotton balls, razors, and hair ties, in a unit about 5.5 inches wide, 12 to 14 inches deep, and 20 to 24 inches tall. Drawers waste some space on their frames, so tall spray bottles will not stand inside. Typically $25–$45.
9. Stackable slim bins with lids. Best for building only as much storage as you need, two or three bins, each about 5.75 inches wide, 12 inches deep, and 7 to 8 inches tall, stack into one tower for cleaners or refills. You must lift or unstack the top bin to reach the bottom one, which gets old with daily items. Typically $15–$28.
What to Buy
Slim 3-tier rolling cart — the best first buy for most bathrooms, because it fits a 6-inch gap, rolls out for cleaning, and holds daily supplies plus a spare roll. Typically $18–$30.
Slim cabinet with one door — the best closed option when cleaners and personal items need to stay hidden and the vanity leaves room for the door to swing. Typically $40–$70.
Standing toilet paper holder with a reserve post — the simplest fix if spare rolls on the floor are the only problem, with no shelves to style or dust. Typically $16–$28.
Mistakes to Avoid
- Measuring only at the top: the bowl, baseboard, and supply line are wider lower down, so measure at floor level too.
- Buying exactly 6 inches for a 6-inch gap: leave a small margin, or the piece will scrape and be hard to pull out.
- Storing heavy bottles up high: tall, narrow pieces tip more easily, so keep cleaners and full bottles on the lowest tier.
- Ignoring the water supply line: a valve or hose behind the toilet can block a deep piece even when the front looks clear.
- Choosing open shelves for private items: if guests use this bathroom, a door, drawer, or lid looks calmer and cleaner.
Frequently Asked Questions
How much space is usually beside a toilet?
Many bathrooms leave about 6 to 9 inches between the toilet and a wall or vanity, but older and smaller bathrooms can leave less. The only safe way to know is to measure your own gap at floor level, mid-height, and the widest part of the bowl, then shop by the smallest measurement.
Will a rolling cart fit if my floor has tile and grout?
Most slim carts roll fine on flat tile, but small wheels can bump over thick grout lines, thresholds, and bath mat edges. Roll the cart slowly, keep heavier items on the bottom tier, and lift it over a raised threshold instead of forcing the wheels across.
What should I store beside the toilet, and what should I skip?
Store spare rolls, wipes, cleaners, and small daily supplies you reach for often. Skip anything that moisture or a splash could ruin, like spare towels you want to keep pristine, paper books, or electronics without a closed cabinet or lid to protect them.
How do I clean under and behind a slim piece?
Pick a piece you can move. Rolling carts and standing holders slide out in seconds, so you can wipe the floor and the baseboard behind them. Fixed or heavy cabinets are harder to move, so clean around the base often and check for moisture after mopping.
A 6-inch gap will not hold everything, but it can hold the things that now clutter the tank and the floor. Measure your gap, pick one piece from this list, and save this post to your bathroom board on Pinterest so the sizes are handy when you shop.
