Bathroom: Sort 整理

Remove everything that doesn't belong.

Bathrooms collect half-empty bottles, expired medications, and duplicates faster than anywhere else. Sort is ruthless here.

The surface rule: only items you use every single day earn counter space. Everything else goes in a drawer or cabinet — even if you use it weekly.

Sort tasks for the Bathroom

Check every product for expiry — toss anything expired, especially medications
Toss products you haven't used in 3+ months
Consolidate duplicates: four half-empty shampoos become one
Remove items that belong in other rooms (books, phone chargers, spare lightbulbs)
Empty under the sink completely; return only what is bathroom-related
Dispose of old razors, empty tubes, and broken accessories
Donate unopened, unexpired products you don't want

What is the Sort phase?

Sort (整理, Seiri) is the first phase: remove every item that doesn't belong in the space. Expired products, duplicates, broken items, and things used elsewhere all leave before any organising begins. You cannot set up a good system around things that shouldn't be there.

Common questions about the Bathroom

How do I stop my bathroom getting cluttered?

The root cause is almost always too many products. Most bathrooms need 8–12 active products, not 40. Sort ruthlessly (toss expired and unused), then assign every product a specific spot. When everything has a home and the total count is low, clutter cannot accumulate.

How long do bathroom products last?

Opened products: moisturisers and serums 6–12 months, sunscreen 12 months after opening, mascara 3 months, foundation 12 months. Most products have a PAO (period after opening) symbol — the jar icon with a number. Medications: always follow the expiry date on the packaging.

What is the best way to organise under the bathroom sink?

Remove everything first — under-sink becomes a black hole without an annual sort. Use a turntable for tall bottles (spray cleaners, hairspray), pull-out drawer organisers for smaller items, and a clearly labelled section for spare stock. The rule: only bathroom supplies, nothing else.

How do I organise a small bathroom with no storage?

Go vertical: an over-door organiser, wall-mounted shelves above the toilet, magnetic strips inside cabinet doors. Reduce total product count aggressively — a small bathroom with 10 products is easy to keep tidy; the same bathroom with 40 products is impossible.
