Why a Drainable Soap Holder is an RV Essential
A standard soap dish is a water trap. In a sticks-and-bricks house, that water eventually evaporates, but in a compact, sealed-up RV, every drop of standing water is an invitation for mildew and humidity problems. A drainable soap holder isn’t a luxury; it’s a critical tool for preserving your soap and, more importantly, the health of your rig.
Mushy soap disappears at an astonishing rate, forcing you to buy it more often. A good draining dish keeps the bar hard and dry, easily doubling or tripling its lifespan. This saves you money and reduces the number of things you need to store—a constant battle in any RV.
Then there’s the travel day consideration. A non-draining dish full of soapy water is a guaranteed mess when you start rolling down the highway. A proper drainable holder ensures the soap is dry and the dish is empty, so you can secure it and go without worrying about cleaning up a slimy spill at your next stop.
Command Bath Soap Dish: No-Drill Reliability
Command products are a nomad’s best friend for a reason. Their water-resistant adhesive strips hold strong in the humid, temperature-swinging environment of an RV shower but come off clean when you want them to. This means you can mount a sturdy soap dish without drilling a single hole into your shower surround—a huge win for preserving your rig’s integrity.
The design is simple and smart. The dish itself has ample drain holes, and it conveniently lifts off the mounting base for easy cleaning. You can scrub out any soap residue in the sink without having to peel the entire apparatus off the wall.
The key to Command’s success is surface prep. Don’t just slap it on the wall. Clean the spot thoroughly with rubbing alcohol first to remove any soap scum or residue. This creates a powerful bond that will hold up through bumpy roads and steamy showers, making it a truly reliable, set-and-forget solution.
OXO Good Grips Suction Dish: Stays Put on the Go
Most people are skeptical of suction cups in a moving vehicle, and for good reason—most of them are junk. The OXO Good Grips line is different. It uses a heavy-duty suction cup activated by a push-lever, creating a vacuum seal that’s dramatically stronger than a simple press-on cup.
This locking mechanism is the game-changer for RV life. It provides the holding power needed to keep a full bar of soap secure, even on rough forest service roads. The ability to unlock it, move it, and re-lock it without leaving any residue is a massive advantage if you’re trying to figure out the perfect shower layout or need to move it for cleaning.
The major caveat is your shower wall surface. Suction only works on perfectly smooth, non-porous materials like glossy fiberglass or acrylic. It will fail on textured surfaces, matte plastics, or any wall with grout lines. If you have the right surface, the OXO offers a powerful, non-permanent hold that’s hard to beat.
Yasonic Adhesive Holder: Sleek and Mildew-Resistant
If you want maximum airflow, this is the style for you. These holders, often made of stainless steel, feature an open, slatted "basket" design instead of a traditional dish with holes. This allows air to circulate all around the soap, drying it out incredibly fast and preventing the dreaded "soggy bottom" that plagues lesser designs.
Installation is typically done with a large, transparent adhesive pad that covers a significant surface area. This distributes the weight effectively and creates an extremely strong, waterproof bond. Be warned: this is a semi-permanent solution. Once that adhesive is on and has cured, it’s not meant to be moved. Measure twice, stick once.
The stainless steel construction is another key benefit. It won’t rust in a damp shower environment and is inherently resistant to mildew growth. It provides a clean, modern look while being one of the most functional and hygienic options available for long-term use.
KINCMAX Caddy Basket: More Than Just a Soap Dish
Sometimes you need more than just a place for your soap. In a tiny RV shower where every inch of wall space counts, a small caddy basket is often a more efficient solution. The KINCMAX and similar brands offer a deep basket design that can hold a bar of soap, a razor, and a travel-sized bottle of shampoo in one consolidated spot.
Like the Yasonic holder, these typically mount with powerful adhesive hooks or pads. The installation is straightforward but requires a clean surface and careful placement. The strength of these adhesives is impressive, easily holding several pounds without issue, which is more than enough for your shower essentials.
The tradeoff is a slightly larger footprint on your wall. However, by combining multiple items into one organizer, you often save space overall compared to mounting a separate holder for each thing. It’s the perfect choice for anyone looking to declutter their limited shower space with a single, robust organizer.
iDesign Cade Soap Saver: Simple, Effective Drainage
This isn’t a wall-mounted solution, but for some RVers, it’s the perfect one. The iDesign Soap Saver is a simple, self-contained plastic tray with raised ridges that elevate the soap bar. This allows water to drain away and air to flow underneath, drying the soap from all sides.
Its brilliance is in its simplicity. There’s no installation, no adhesive to fail, and no suction cups to worry about. You simply place it on any built-in shelf or ledge in your shower. For cleaning, you just pick it up and rinse it in the sink.
The obvious downside is that it’s not secured for travel. This makes it an ideal choice for full-timers who tend to stay in one place for weeks or months at a time. For those who are constantly on the move, you’ll need to remember to stow it before you pull up the jacks.
Teak Wood Soap Dish: A Natural, Stylish Solution
For those who want to avoid the plastic look, a teak wood soap dish is a fantastic alternative. Teak is a tropical hardwood that is naturally rich in oils, making it highly resistant to water, mold, and mildew. It brings a touch of warmth and natural texture to what can often be a sterile, all-fiberglass environment.
These dishes are almost always freestanding, designed to sit on a shower ledge just like the iDesign saver. They feature wide slats that allow for excellent drainage and airflow, keeping your soap bar firm and dry. The material itself is durable and won’t get slimy or degraded by constant water exposure.
While teak is low-maintenance, it does benefit from a light coat of teak oil once or twice a year to keep it looking its best. This is a great choice for RVers who prioritize natural materials and aesthetics, and who don’t mind stowing an item on travel days.
Choosing Your RV Soap Holder: Adhesion vs. Suction
Your decision ultimately comes down to your shower’s wall surface and your need for permanence. There is no single "best" method; there’s only the best method for your specific rig. Before you buy anything, go inspect your shower.
Adhesive mounts are your go-to for semi-permanent, worry-free installation. They are the most reliable option for surviving bumpy travel days and work on a wider variety of surfaces, including lightly textured ones. The downside is that they are difficult to remove and cannot be repositioned. This is the "set it and forget it" choice.
Suction mounts offer fantastic flexibility, but only on the right surface. If your shower is perfectly smooth, high-gloss acrylic or fiberglass, a quality locking suction cup like OXO’s is an excellent, damage-free option. You can move it anytime you want. However, it will fail on any other surface, so don’t even try it on textured walls.
Take a moment to decide if you want to commit to a location or prefer the freedom to rearrange. Answering that question, combined with a quick check of your shower wall material, will point you directly to the right soap holder for your life on the road.
That soggy bar of soap isn’t just an annoyance; it’s a small signal from your environment. By choosing a soap holder that drains properly and stays put, you’re not just saving soap—you’re practicing the art of intentional living in a small space. It’s these thoughtful little upgrades that transform an RV from a vehicle into a comfortable and efficient home.
Frequently Asked Questions (FAQs)
What is a drainable soap holder for an RV shower?
A drainable soap holder for an RV shower is a tray or caddy designed with angled spouts, slots, or channels to direct standing water away from bar soap. This design prevents the soap from dissolving into mush when moisture builds up in compact motorhome stalls. Most camper models secure directly to smooth fiberglass surfaces using suction cups or waterproof adhesive strips to remain stable during transit. For best results, place the holder near the edge of the shower basin so runoff drains directly into the pan.
What does a waterfall soap dish do in an RV shower?
Waterfall soap dishes use a downward-sloping spout to funnel excess water directly off the tray and into the shower drain. Instead of collecting liquid beneath the soap bar, the open-ended channel allows gravity to evacuate water continuously after bathing. This feature prevents soap bars from softening and leaves fewer slimy residues on delicate camper wall panels. Users should aim the spout lip slightly downward over a shower shelf edge or shower tub ledge for passive drainage.
How do you mount a drainable soap holder in an RV shower without drilling?
Mounting a drainable soap holder without drilling requires either heavy-duty waterproof adhesive strips or silicone-backed locking suction cups rated for humid environments. Clean the fiberglass or plastic shower wall thoroughly with 70 percent isopropyl alcohol to strip away dirt and soap residue, then let it dry. Press adhesive pads firmly against the surface for 30 seconds and cure for 24 hours before loading any soap weight. For textured RV walls, choose acrylic foam adhesive pads rather than standard suction cups to maintain a reliable hold.
How do you clean RV shower soap scum out of a drainable soap dish?
Cleaning soap scum from a drainable soap dish requires soaking the holder in warm water mixed with mild dish soap or distilled white vinegar. Let the tray soak for 10 to 15 minutes to soften dried lather and mineral scale inside the drainage slots. Scrub the interior channels with an old nylon toothbrush to dislodge buildup without scratching plastic or silicone finishes. Rinse the holder with fresh water and dry it before reattaching it to the camper wall.
Are silicone soap dishes better than plastic soap dishes for RV showers?
Silicone soap dishes are generally better than rigid plastic soap dishes for RV showers because flexible silicone will not crack, shatter, or rattle while driving. Soft silicone grips slick fiberglass ledges naturally, stopping soap from sliding onto the floor on rough roads. Hard plastic models offer rigid drainage spouts but can snap under road vibration or travel impacts. Choosing food-grade silicone also helps resist mold in humid, poorly ventilated camper bathrooms.
How much does a quality drainable soap holder for an RV shower cost?
Prices for a quality drainable soap holder for an RV shower typically range from $6 to $18, depending on the material and mounting system. Single silicone self-draining trays usually sell for $6 to $10. Wall-mounted holders equipped with rustproof stainless steel brackets, suction mechanisms, or multi-pack sets range between $12 and $18. Premium rust-resistant aluminum caddies with removable drainage trays can reach $20 to $25, though budget silicone models provide adequate durability for most motorhome owners.
Why does a suction cup drainable soap holder keep falling off in an RV shower?
Suction cup soap holders fail on RV shower walls when mounted over textured plastic, porous fiberglass, seams, or surfaces carrying soap residue. Standard suction cups need a completely smooth, non-porous surface to maintain an airtight seal, and many factory RV wall panels have subtle pebble texturing. Temperature fluctuations inside parked campers also cause air pockets behind the rubber cup to expand and break vacuum pressure. Applying an adhesive mounting disc or switching to waterproof acrylic foam tape fixes the problem immediately.
Are drainable soap holders worth using in small camper showers?
Installing a drainable soap holder is worth it in small camper showers because it extends bar soap life and prevents sticky messes in tight spaces. Commercial bar soap softens rapidly when trapped in pooled water, wasting product and leaving stubborn stains on fragile RV wall surrounds. Elevating the bar allows airflow to dry the soap between campground stops while catching graywater runoff before it stains. Wall-mounted versions also free up scarce shelf space on tiny corner RV shower ledges.
