6 Best Bathroom Cleaning Supplies for Small Spaces That Serve Multiple Needs
Small bathroom? Discover 6 versatile cleaning supplies that serve multiple needs, saving you precious storage space while delivering a powerful, sparkling clean.
That tiny cabinet under your bathroom sink feels more like a puzzle box than storage, and every single-use cleaning bottle is a piece that just won’t fit. In a small home, RV, or van, every square inch is prime real estate you can’t afford to waste on a dozen different cleaners. The solution isn’t to clean less; it’s to choose smarter tools that pull double or triple duty.

Choosing Multi-Use Cleaners for Tiny Bathrooms
The biggest mistake people make when outfitting a small space is replicating the cleaning supply closet from a traditional home. A bottle of glass cleaner, a tub of scouring powder, a spray for tile, another for the toilet—it’s a recipe for instant clutter. In a tiny bathroom, your entire cleaning arsenal might need to fit in a shoebox-sized space.
This reality forces a shift in mindset. Instead of buying products for tasks, you need to buy products for properties. Look for items that are:
- Concentrated: A small bottle of concentrate that you dilute yourself can replace multiple full-size, ready-to-use spray bottles.
- Versatile: Can it clean glass, tile, and the toilet bowl? The more surfaces a single cleaner can handle, the more valuable it is.
- Compact: Every tool, from the scrub brush to the bucket, must be designed for efficient storage.
This doesn’t mean you can get by with just one magic bottle for everything. The goal is to build a core kit of versatile workhorses and supplement it with one or two highly effective specialists for tough jobs. It’s a strategic balance, not an exercise in extreme, and often impractical, minimalism.
Dr. Bronner’s Sal Suds: The One-Bottle Wonder
Forget a lineup of different sprays. Sal Suds is the cornerstone of my small-space cleaning kit because it’s a ruthlessly effective, biodegradable, and highly concentrated detergent. It’s not a soap; it’s a surfactant designed to cut through grease and grime on virtually any hard surface.
Its power lies in dilution. I keep one small spray bottle of diluted Sal Suds (about a tablespoon per 16 ounces of water) for everything from wiping down the sink and countertop to cleaning the outside of the toilet. A couple of undiluted drops on a brush are enough to scrub the toilet bowl. A small capful in a bucket of water mops the floor. One small bottle of concentrate replaces at least three other products.
The key tradeoff to understand is that Sal Suds is a cleaner, not a registered disinfectant. For most daily cleaning, this is perfectly fine. If you need to disinfect after someone’s been sick, you might need a separate product, but for 99% of bathroom cleaning, Sal Suds gets the job done without filling your cabinet.
OXO Squeegee & Scrubber for Streak-Free Walls
In a tiny bathroom, especially in an RV or van, moisture is your number one enemy. Poor ventilation turns every shower into a potential mold and mildew incubator. A squeegee isn’t just a tool for streak-free glass; it’s your first line of defense against moisture damage.
The OXO Good Grips All-Purpose Squeegee is a perfect example of a tool that does more than one job well. One side is a standard squeegee blade for quickly clearing water from shower walls and doors, a ritual that takes 30 seconds but prevents hours of future scrubbing. The other side features a soft, non-scratch scrubber. This is brilliant because you can use it to apply a bit of Sal Suds to tackle a stubborn spot of soap scum right when you see it.
Achieve streak-free surfaces quickly with the OXO Good Grips Squeegee. Its flexible blade easily dries shower doors, mirrors, and windows, while the included suction hook offers simple storage.
Best of all, its design understands the constraints of a small shower. It comes with a suction cup hook, so it lives on the wall, taking up zero shelf or cabinet space. It’s always there, ready to use. This isn’t just a cleaning tool; it’s a moisture management system that stores itself.
E-Cloth Bathroom Pack: Chemical-Free Wiping
Achieve a spotless bathroom with this premium microfiber kit. The specialized cloths remove soap scum and bacteria with just water, leaving surfaces streak-free and shining. Reusable and washable, it's an eco-friendly alternative to sprays and wipes.
Sometimes the most multi-functional tool is the one that eliminates the need for others. The E-Cloth system is built on high-quality microfiber that can remove over 99% of bacteria from a surface with just water. This drastically reduces your reliance on chemical sprays and completely eliminates the need for paper towels.
Achieve a streak-free shine on windows, mirrors, and glass with just water. This two-cloth system uses a waffle-weave cloth to lift grime and a smooth-weave cloth to polish, leaving surfaces spotless and clear. Machine washable and reusable for long-term savings.
The Bathroom Pack typically includes two cloths. The primary cleaning cloth has a scrubby corner for tougher grime, making it versatile enough for the sink, faucet, and shower tile. The second is a glass and polishing cloth that leaves mirrors and chrome fixtures completely streak-free with no cleaner required.
This approach requires a small shift in habit. You have to rinse the cloths well after use and launder them regularly to keep them effective. But the payoff is huge. You’re storing two thin, foldable cloths instead of a bulky roll of paper towels and a bottle of glass cleaner. For anyone sensitive to chemical fragrances or trying to live more sustainably, this is a clear winner.
CLR for Tough Hard Water Stain Removal
Even the best all-purpose cleaner has its limits. If you live in an area with hard water, or if you’re in an RV filling your tank from various sources, you will eventually face stubborn calcium, lime, and rust stains. This is where a specialist product earns its keep.
CLR Brilliant Bath is the one single-task cleaner I allow in my minimalist kit. A small bottle of this stuff is uniquely formulated to dissolve mineral deposits and soap scum that all-purpose cleaners just can’t touch. A quick spray melts away the chalky white buildup on your shower head and faucets, saving you from endless, fruitless scrubbing.
Effortlessly tackle tough bathroom grime with CLR Brilliant Bath Foaming Cleaner. This EPA Safer Choice certified formula quickly eliminates dirt and buildup from toilets, showers, sinks, glass, and stainless steel. Simply spray and wipe for a brilliant clean with a fresh scent.
Think of it as a tactical tool, not an everyday cleaner. You might only use it once a month, but its effectiveness means you don’t need abrasive powders or heavy-duty scrub pads that take up more space and can damage surfaces. By solving the toughest problem efficiently, CLR lets your other multi-use products handle the daily work.
simplehuman Toilet Brush: A Compact Solution
This simplehuman toilet brush features a crescent-shaped head for efficient cleaning under the rim and stiff bristles for tough stains. Its drip-free magnetic collar and discreet, dome-shaped caddy ensure hygienic storage.
A toilet brush is a non-negotiable item, but most are an eyesore and a storage headache. They are often flimsy, drip everywhere, and sit in a clunky, open-air base. In a tiny bathroom where the toilet is often inches from your shower, a hygienic and well-designed brush is essential.
The simplehuman Toilet Brush is an investment, but it solves multiple problems with smart design. The holder is slim and discreet, with a narrow profile that tucks away neatly. More importantly, it features a magnetic collar that secures the brush to the cover, so you can carry the entire unit without any drips. The cover also allows for airflow, letting the brush dry quickly and reducing odor.
While it technically only performs one cleaning task, its design serves the multiple needs of sanitation, compact storage, and discreet appearance. The crescent-shaped brush head is also designed to get up under the rim effectively. It’s a perfect example of how a well-designed version of a basic tool can be a multi-functional asset in a small space.
Camco Collapsible Bucket: Space-Saving Utility
This durable, collapsible bucket holds 3 gallons of water and features watertight fabric for reliable use. It folds flat for easy storage in the included zippered case, making it ideal for RVing, camping, fishing, and boating.
You don’t need a bucket often, but when you do, you really need one. Whether you’re mopping the floor, hand-washing delicate clothes, or needing to catch a drip from a leaky pipe, a standard bucket is invaluable. The problem? A 3- or 5-gallon bucket is a massive space-waster.
The solution is a collapsible bucket. Camco makes a popular model for the RV market that holds over 3 gallons but collapses down to less than two inches thick. It can slide behind a toilet, under a sink, or into a sliver of space in an external storage bay. It’s the definition of having utility without the storage penalty.
This tool’s value extends beyond just cleaning. It can serve as a laundry hamper, a trash can in a pinch, or a carrier for tools. Its ability to practically disappear when not in use makes it one of the most valuable multi-purpose items you can own in a tiny home.
Maintaining Your Minimalist Bathroom Cleaning Kit
Your minimalist kit is only effective if it’s ready to go. The key is to create a system that makes cleaning easy, not an expedition to gather supplies. Keep your diluted Sal Suds in a labeled spray bottle under the sink. Store the squeegee in the shower and the E-Cloths in a small basket or drawer.
This isn’t about deprivation; it’s about efficiency. With this core set of six items, you can handle virtually any cleaning task your small bathroom throws at you. You have a daily cleaner (Sal Suds), a preventative tool (squeegee), a chemical-free option (E-Cloth), a heavy-hitter (CLR), and the necessary essentials (toilet brush and bucket) that are all designed to minimize their own footprint.
The real benefit goes beyond saving a few cubic inches of cabinet space. It simplifies the act of cleaning itself. When you only have a few highly effective tools to choose from, you spend less time thinking about what to use and more time getting the job done. That mental clarity is one of the greatest luxuries of small-space living.
Ultimately, a well-curated cleaning kit is a foundation of thriving in a small space. By choosing versatile, compact, and effective supplies, you reclaim valuable storage and create a system that keeps your tiny bathroom clean without the overwhelming clutter of products.
