Bathroom cabinets fill with expired products and triplicate purchases because nothing has a zone. Purge by date first, then give every person and every category one labeled territory.

Empty one cabinet at a time onto a towel. The first cut requires no judgment: check dates and the open-jar symbol (the little tub icon with '12M' or '6M' - months safe after opening). Expired medicine, sunscreen past its date, mascara older than three months, anything that has changed smell or texture - out. Sunscreen and medicine actually lose effectiveness; this is safety, not minimalism.
Second cut is the honesty pass: the hotel minis, the hair product that didn't work, the fourth body lotion. If you have not reached for it in six months, it leaves - usable unopened items can go to a shelter donation, the rest to the bin. Most bathrooms lose a third of their contents here and feel nothing but relief.
Give each household member one shelf, drawer, or bin - their kit lives there and nowhere else. Shared categories get their own zones: dental together, first aid together, cleaning supplies under the sink. The moment everything has an address, the counter clears itself, because 'away' is now a real place.
Within each zone, daily items sit front and at eye level; weekly items behind; monthly up high or down low. The five things you use every morning should be reachable with one hand, eyes closed. Storage that fights your routine loses to the countertop every time.
Under-sink cabinets fail because they are one tall void interrupted by a pipe. Add structure: stacking drawers or a two-tier pull-out turn the void into addressable layers - cleaning products in one, backstock in another, period products or grooming tools in a third.
A small lazy Susan handles the corner dead zone, and door-mounted racks hold the hairdryer and straighteners (heatproof, and they free a whole drawer). Measure around the pipe before buying anything; the pipe is why generic organizers so often go back to the shop.
The bathroom is the warmest, steamiest room in the house - the worst storage conditions for medication, which wants cool, dry, and dark. Move actual medicine to a high kitchen cupboard or a lidded box in a bedroom closet, far from children's reach, and let the 'medicine cabinet' hold what it actually should: daily grooming and dental.
Keep a small first-aid kit in the bathroom - plasters, antiseptic, tweezers - because that is where cuts get washed. The pharmacy takes back expired medicine; it should not go in household bins or down the toilet.
Triplicate shampoo happens because backstock is invisible. Create one backstock bin - one, total - for spares: the next toothpaste, the next soap, the spare razor heads. When you take the last item from the bin, it goes on the shopping list. One in use, one in reserve, none in the cabinet of forgotten purchases.
Decant only where it earns its keep (cotton pads in a jar, yes; shampoo into matching amber bottles, only if you will actually refill them). Labels on bins beat aesthetics on shelves - the system other people in the house can follow is the one that survives.
Look for the open-jar symbol with a number like 6M or 12M - months after opening. Rules of thumb: mascara 3 months, liquid foundation 6 to 12, powders 1 to 2 years, skincare in pumps outlasts jars. Changed smell, color, or separation overrules any date.
Rolled in a basket on the floor or a shelf above the door - rolling shows every towel and fits awkward spaces. Keep two per person in rotation and store the bulk linen elsewhere; the bathroom only needs this week's towels.
One scoop-and-drain toy net or caddy that hangs in the shower, and one low bin they can reach for their own toothbrush and flannel. If they can reach their zone, they can put things back in it - which is the entire point.
A date-check twice a year - tie it to the clock change so it is automatic. Five minutes per cabinet keeps the system alive; the full rebuild only happens once if the zones and the backstock bin survive.
