Welcome to Day 10. Double digits — and if you’ve been with us since the beginning, I hope you’re feeling the real and cumulative effect of everything we’ve cleared and reset together over the past week and a half. Each space builds on the last, and by now your home is genuinely starting to feel different in the best possible way.

Today we’re tackling one of the most universally avoided spaces in the entire home — under the bathroom sink. And I promise it’s so much less daunting than it sounds. It’s a small space, it goes quickly, and the satisfaction of opening that cabinet afterward and knowing exactly what’s in there is one of the best feelings in this whole challenge.

Let’s talk about two different approaches to this space, because I think they’re both worth knowing about.

The Guest Bathroom — A Hospitality Toolkit

Here’s a way of thinking about the under-sink space in a guest bathroom that completely changed how I use ours: treat it as a hospitality toolkit. Everything a guest could possibly need, organized and accessible, completely out of sight so the rest of the bathroom stays calm and beautiful.

In our guest bathroom, that means extra toilet paper, a small waste bin, extra bin bags, cotton buds, and anything else a guest might reach for during their stay. Everything lives under the sink, neatly contained, so the surfaces above stay clear and the bathroom feels welcoming and considered rather than cluttered.

This approach does two things really beautifully. It makes your guests feel genuinely taken care of — there’s something so warm about a bathroom that quietly has everything you need without you having to ask. And it keeps the rest of the bathroom looking the way you want it to look, with clean surfaces and nothing to distract from the overall feel of the space.

If your guest bathroom under-sink storage isn’t functioning this way yet, today is a wonderful day to set it up. It takes very little time and makes a meaningful difference in how your guests experience your home.

Your Personal Bathroom — Clear Storage That Actually Works

For your own bathroom, the under-sink space is most valuable when it’s organized in a way that makes your daily routine genuinely easier. The goal is being able to find what you need immediately, without digging through a cabinet full of things you forgot you had.

Clear storage drawers are one of the best investments you can make for under-sink organization — they let you see everything at a glance, keep categories separated, and make the whole space feel intentional rather than chaotic. In our bathroom, I use clear drawers to house my hair products and accessories, which means everything has a home and I can see exactly what I have without opening a single thing. It makes getting ready so much more streamlined and enjoyable.

The key to making this work long-term is being genuinely honest about what you’re keeping. The products you actually use every day earn their place in the most accessible spot. Everything else gets evaluated today — the half-empty bottles, the products you bought with enthusiasm and never finished, the duplicates you forgot you already had. If you haven’t reached for something in the past month, it probably doesn’t need to live in your most-used bathroom storage.

How to Declutter Under the Bathroom Sink Today

Give yourself 20 minutes for this one. It goes faster than you think and feels so good on the other side.

Step 1: Take everything out. Every single thing. Lay it all out on the floor or the counter so you can see exactly what you’re working with. This step is always a little surprising — most under-sink cabinets contain significantly more than people remember.

Step 2: Clean the cabinet. Before anything goes back in, wipe down the interior of the cabinet completely. Clean the floor of it, the walls, the inside of the door if it has one. A clean cabinet is a genuinely motivating thing to put things back into.

Step 3: Sort honestly. Go through everything and sort into keep, donate, and let go. For beauty and personal care products specifically — check expiration dates, be honest about what you actually use, and let go of anything that’s been sitting untouched for more than a few months. Half-empty bottles of products you don’t love are not serving you by staying under your sink.

Step 4: Think about what the space needs to do. Before you put anything back, think about the purpose of this specific bathroom. Is it a guest bathroom that should function as a hospitality toolkit? Is it your personal bathroom where your daily routine needs to flow easily? Let the purpose guide the organization.

Step 5: Invest in clear storage if you haven’t already. Clear bins, clear drawers, or a simple tiered shelf organizer make an enormous difference in how functional an under-sink cabinet feels. When you can see everything at a glance, you stop buying duplicates of things you already have and you stop reaching past things to find what you need. It’s one of those small investments that pays off every single day.

Step 6: Return only what belongs. Put back only the items that genuinely earn their place in this cabinet. Give everything a specific, consistent home. Your most-used items go in the most accessible spot. Less-frequent items can live further back or higher up.

Step 7: For the guest bathroom, set it up as a hospitality kit. Extra toilet paper in a beautiful basket, a small waste bin, extra bags tucked inside it, cotton buds in a pretty container, anything else your guests might need. Neat, contained, and completely out of sight. Your guests will notice, even if they don’t say so.

Small Space, Big Impact

Under the bathroom sink might be one of the smallest spaces in your home, but the impact of getting it right is felt every single day. Every time you open that cabinet and find exactly what you’re looking for — every time a guest reaches for something they need and it’s right there waiting for them — the effort of today pays off. That’s what this challenge is about. The small spaces matter just as much as the big ones.
