What is the Sustain phase?

Sustain (躾, Shitsuke) is the hardest phase and the reason most organisation attempts fail. It means building the habits, schedules, and accountability that keep the previous four phases working over time. The goal is a home that maintains itself — not through constant effort, but through well-designed routines that become invisible.

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.
