10 RV Shower Conversions for Extra Storage in Small Campers

Finding enough storage space in a compact trailer or camper van often feels like an endless game of Tetris. When you primarily camp at state parks with public facilities or boondock with limited freshwater, that bulky, rarely used RV shower becomes prime real estate. Converting this underutilized wet bay into a functional closet or pantry is one of the smartest ways to instantly maximize your living footprint on the road.

Why Convert an RV Shower Into Extra Storage

Space is the ultimate currency in any mobile rig under 24 feet. An RV shower occupies roughly 6 to 10 square feet of precious floor-to-ceiling space, yet many travelers prefer public campground bathhouses or outdoor solar showers. Leaving this area empty while squeezing gear into overhead bins is an inefficient use of resources.

Converting the shower stall into temporary or semi-permanent storage allows for better weight distribution and organization. Heavy dry goods, winter coats, or bulky gear can sit low in the basin, lowering your vehicle’s center of gravity. Additionally, because the shower is already built to be waterproof and has a built-in drain, it acts as an ideal containment zone for damp gear, muddy boots, or laundry.

The key to a successful conversion is flexibility. The best setups utilize damage-free, removable storage solutions that do not require drilling into fragile fiberglass shower surrounds. This keeps your options open, allowing you to revert the space back to a fully functioning shower in minutes when resale value or a change in travel style demands it.

Tension Closet Rod – RoomDividersNow Tension Rod

When converting a shower into a closet, hanging space is the first thing you need to establish. A heavy-duty tension rod bridges the gap between the wet walls without requiring permanent drilling or risking water leaks through screw holes. It instantly turns the top of your shower stall into a high-capacity wardrobe for coats, button-downs, or wet gear.

The RoomDividersNow Tension Rod stands out because of its robust spring-loaded tension and heavy-duty hold. Unlike flimsy plastic shower curtain rods that slip off slick fiberglass at the first bump on a washboard road, this premium steel rod features oversized end caps with non-slip rubber grips. It can easily handle the dynamic weight of heavy winter jackets bouncing during transit.

• Diameter options: 0.75-inch or 1-inch models
• Width range: Small (28″-50″) fits most standard RV showers
• Weight capacity: Up to 20 pounds of hanging weight
• Materials: Rust-resistant finished steel

Before installing, measure the distance between your shower walls carefully at the exact height you plan to mount the rod. To prevent the rod from slipping during travel, place a small piece of non-slip shelf liner between the rubber end caps and the shower wall. This product is ideal for travelers needing extra hanging clothes storage, but it is not recommended for ultra-flexible plastic shower panels that might bow under high tension.

Hanging Organizer – MISSLO Hanging Closet Organizer

MISSLO 30 Large Pockets Dual Sided Hanging Shoe Organizer for Closet with Rotating Hanger Hanging Shoe Shelves, Grey

Vertical space is often wasted in standard RV layouts, leaving a massive gap of empty air above the shower floor. A hanging organizer attaches directly to your new tension rod, creating instant shelving without adding heavy wooden structures. This approach keeps your essentials organized, visible, and off the damp shower pan.

The MISSLO Hanging Closet Organizer is a top choice due to its dual-sided design and durable, breathable fabric construction. It features heavy-duty metal hooks that fit securely over your tension rod, resisting the swaying motion of a moving rig. With structured, sag-resistant shelves and mesh side pockets, it holds clothing, towels, or dry food items securely without collapsing under load.

• Compartments: Multiple vertical cubbies plus elastic mesh side pockets
• Material: Heavy-duty oxford fabric with rigid cardboard inserts
• Attachment: Two rotating metal hooks
• Best uses: Storing folded t-shirts, rolled towels, underwear, and toiletries

Be mindful of total weight limits when loading this organizer, as overloading can cause your tension rod to slip. Always pack heavier items in the bottom compartments to keep the center of gravity low and reduce sway while driving. This system is perfect for solo travelers or couples looking for clothing drawers, but it is less suited for heavy, sharp-edged tools or loose hardware.

Storage Drawer Tower – Iris USA 3-Drawer Wide Chest

If you prefer drawer storage over open hanging shelves, a plastic drawer tower placed directly on the shower floor is the perfect solution. It keeps your items enclosed, dust-free, and organized while utilizing the lower half of the shower stall. A freestanding unit prevents the need to mount permanent drawers into your camper’s thin walls.

The Iris USA 3-Drawer Wide Chest is ideal for this application because of its durable, lightweight plastic frame and built-in drawer stops. The clear drawers let you instantly identify what is inside without rummaging, which is a massive time-saver in a dark RV bathroom. Its plastic construction means it is completely impervious to any residual moisture in the shower pan or high humidity levels.

• Dimensions: 14.25″ D x 21.25″ W x 24″ H (fits most standard shower pans)
• Features: Ergonomic drawer pulls, secure drawer stops, optional removable wheels
• Weight: Extremely lightweight when empty
• Utility: Ideal for pantry items, folded garments, or dog supplies

Always measure the interior width of your shower pan at its narrowest point, as some molded fiberglass pans taper near the bottom. To prevent the tower from sliding around while driving, use a tension bar or bungee cords across the front of the unit, anchored to the shower walls. This setup is perfect for those needing dedicated pantry or clothing drawers but is not suited for narrow neo-angle corner showers.

Stackable Storage Bins – Rubbermaid Cleverstore Tote

Rubbermaid Cleverstore 16 Qt Clear Storage Bins with Latching Lids, 6-Pack, Stackable, BPA-Free, Made in USA

For rugged gear, tools, or seasonal clothing, modular stackable bins offer the most secure and weather-tight storage solution. When stacked inside a shower stall, they utilize the structural strength of the basin to hold heavy loads. Bins keep your gear dry, contained, and easy to unload if you ever need to use the shower in an emergency.

The Rubbermaid Cleverstore Tote is a stellar choice because of its straight-wall design, which maximizes interior packing space compared to tapered bins. The clear plastic construction ensures you never have to guess which bin contains your spare parts or winter blankets. The latching lids snap tightly in place, keeping moisture, dust, and pests away from your stored goods.

• Capacity: 16-Quart or 30-Quart sizes fit well in small camper spaces
• Lid type: Secure latching handles
• Stackability: Deep recessed lids for secure stacking during transit
• Material: Shatter-resistant, BPA-free clear plastic

When stacking these totes in an RV shower, place the heaviest bins at the bottom of the stack to prevent tipping on sharp turns. Secure the stack with a simple cargo strap or a tension bar placed horizontally across the front of the bins. This system is best for long-term travelers carrying seasonal gear or extra dry goods, while those needing quick, daily access to small items might find unlatching bins tedious.

Tension Shower Caddy – Simplehuman Tension Caddy

simplehuman 8' Tension Pole Shower Caddy, Stainless Steel and Anodized Aluminum

If you want to retain the ability to use your shower occasionally while still gaining organized storage, a vertical tension corner caddy is the perfect compromise. It utilizes dead corner space that is usually wasted. This allows you to store toiletries, cleaning supplies, or small gear items securely in one spot without blocking the entire shower stall.

The Simplehuman Tension Caddy is the gold standard for this setup due to its premium, corrosion-resistant materials and robust spring mechanism. The high-gauge stainless steel pole expands to fit tightly between the shower floor and ceiling, holding its position even over bumpy roads. Its adjustable wire shelves can be slid up, down, or sideways to accommodate tall bottles or odd-sized gear.

• Height range: 6 feet to 9 feet (fits standard and tall RV showers)
• Materials: Rustproof stainless steel and anodized aluminum
• Shelving: Adjustable wire baskets with built-in storage hooks
• Footprint: Minimal corner impact

Be sure to check your RV ceiling strength before cranking the tension too high, as some lightweight ceiling panels can flex under pressure. Placing a small wooden block or rigid plastic plate between the top pad and the ceiling can distribute the pressure safely. This caddy is perfect for travelers who want to keep their shower functional while keeping small items organized, but it is not meant for storing bulky clothing or large gear.

Slim Rolling Cart – Spacekeeper 3-Tier Utility Cart

A slim rolling cart is an incredibly versatile option for RV shower storage because it can be wheeled out of the way in seconds. This allows you to use your shower stall for bathing when needed, then roll the storage unit right back in place afterward. It is a highly dynamic solution for tiny campers where multi-functional spaces are essential.

The Spacekeeper 3-Tier Utility Cart is perfectly sized to slide into the narrow gaps found in standard camper showers. Constructed from durable plastic shelves and rust-resistant steel rods, this cart resists the damp environment of a bathroom with ease. The smooth-gliding casters make moving the cart effortless, even when it is fully loaded with canned food, cleaning supplies, or laundry essentials.

• Width: Only 5.1 inches wide, making it exceptionally slim
• Mobility: 360-degree rotating wheels for easy maneuverability
• Shelving: Three deep tiers to prevent items from falling out during transit
• Material: Heavy-duty plastic and stainless steel supports

Because this cart rolls freely, you must secure it while the RV is in motion to prevent it from slamming into your shower door or walls. A simple bungee cord hooked to the shower grab bar or a tension rod placed across the opening will keep it locked in place. This product is ideal for weekend warriors who need temporary storage that can be easily relocated, but it is not stable enough on its own for rough off-road travel without proper tie-downs.

Cargo Netting – Organized Obie Elastic Cargo Net

Keeping items from shifting while driving is one of the biggest challenges of RV living. Cargo netting acts as a lightweight, flexible barrier that turns your entire shower opening into a secure holding pen. This prevents loose items, bulk gear, or even sleeping bags from spilling out onto the bathroom floor when you open the shower door after a long drive.

The Organized Obie Elastic Cargo Net is specifically designed for the harsh vibrations and tight spaces of the mobile lifestyle. Unlike cheap, saggy nets, this professional-grade cargo barrier features a heavy-duty elastic shock cord and durable polypropylene webbing that retains its shape over time. It can be mounted directly to the wood frame surrounding your shower using simple screw-in buttons or adhesive mounts.

• Mounting options: Screw-mount buttons or adhesive backing
• Webbing material: UV-resistant polypropylene
• Sizes: Multiple configurations to fit standard RV door frames
• Elasticity: Strong rebound stretch to hold bulky items snugly

If you prefer not to drill into your RV’s walls, choose the adhesive mounting pucks, but ensure the surface is thoroughly cleaned with rubbing alcohol first to guarantee a strong bond. This cargo net is an excellent choice for holding soft items like sleeping bags, pillows, or laundry bags securely in the shower, but it is not intended to hold sharp or heavy metal tools that could snag the mesh.

Collapsible Basket – CleverMade Collapsible Basket

When space is tight, your storage solutions should be as adaptable as possible. Collapsible baskets are perfect for RV shower conversions because they can expand to hold laundry, groceries, or gear, and then fold flat when not in use. This flexibility is vital when you need to transition your shower back to its original purpose quickly.

The CleverMade Collapsible Basket combines the rigidity of a solid plastic crate with the space-saving benefits of a folding bag. It features a patented snap-hinge system that locks open securely, preventing the basket from collapsing unexpectedly when loaded with gear. The durable materials are easy to wipe down, making it excellent for carrying damp towels or wet swimsuits straight from the shower stall to the laundromat.

• Capacity: 30 Liters (8 Gallons) of storage capacity
• Folded profile: Folds down to less than 3 inches thick
• Load capacity: Supports up to 55 pounds of weight
• Handles: Heavy-duty, comfortable side grip handles

Keep in mind that while these crates are highly durable, stacking heavy, unyielding objects on top of them when they are folded flat can damage the plastic hinges over time. Store them vertically or on top of your gear stack when they are collapsed. This basket is perfect for RVers who need a multi-use utility bin for laundry or grocery runs, but it is less ideal for those looking for fixed, permanently compartmentalized shelving.

Compact Dehumidifier – Eva-Dry E-333 Dehumidifier

Moisture is the mortal enemy of any RV, and converting a wet shower into a dry storage space can trap humidity. Without proper airflow, closed shower stalls can quickly become breeding grounds for mold and mildew, ruining clothes or dry goods stored inside. Placing a compact, cordless dehumidifier in the stall is a non-negotiable step for protecting your belongings.

The Eva-Dry E-333 Dehumidifier is the perfect choice for small RV bathrooms because it requires zero electricity to run. It utilizes renewable silica gel crystals to quietly absorb moisture from the air, completely eliminating the need for noisy fans or messy water reservoirs that could spill during transit. Once the indicator beads change color, you simply plug the unit into an outlet outside the shower to dry it out and renew it.

• Coverage area: Up to 333 cubic feet (perfect for RV bathrooms)
• Power requirement: 100% cordless, needs no batteries or power to absorb moisture
• Lifespan: Reusable for up to 10 years
• Safety: Non-toxic, spill-proof, and child/pet safe

Note that the renewal process requires plugging the unit into a 110V wall outlet for 12 to 15 hours, during which it releases heat and moisture. It is best to do this while plugged into shore power at a campsite or via a robust solar/inverter setup. This unit is essential for any RVer storing fabric, paper, or dry food in a converted shower, but it is not designed to dry out a soaking-wet space after a shower has just been run.

Wall Pegboard – Wall Control Metal Pegboard Organizer

Utilizing the vertical flat surfaces of your shower walls can turn a narrow stall into a highly efficient tool or kitchen pantry station. A wall-mounted pegboard allows you to customize your storage configuration with hooks, brackets, and bins that can be repositioned as your gear needs change. This keeps frequently used items off the floor and within arm’s reach.

The Wall Control Metal Pegboard Organizer is a top-tier choice because its heavy-duty steel construction will not warp, sag, or degrade in a high-humidity environment like traditional pressboard panels. The galvanized steel panels are rust-resistant and feature a dual-slotted and round peg design, offering superior holding strength for heavy tools, hoses, or kitchen cast iron.

• Material: 20-gauge galvanized steel construction
• Mounting: Installs easily with built-in mounting flanges
• Compatibility: Accepts standard 1/4-inch pegs and proprietary slotted hooks
• Durability: Over ten times stronger than traditional pegboards

Because drilling into fiberglass shower walls can lead to leaks if you ever decide to use the water system again, consider mounting these panels to a sturdy piece of plywood wedged tightly into the shower stall instead, or use heavy-duty VHB adhesive tape. This pegboard is an outstanding option for travelers turning their shower into a dedicated workshop or kitchen pantry, but it is overkill for those only looking to store light clothing.

Managing Moisture in Your Converted RV Shower

Moisture management is a critical factor when repurposing any RV wet bay. Even if you never turn on the shower tap, the bathroom is naturally subject to high humidity from cooking, breathing, and adjacent sink use. Left unchecked, stagnant air trapped behind a closed shower door can lead to mold growth on your stored fabrics and cardboard packaging.

To prevent these issues, always keep the RV bathroom roof vent cracked open, and run the exhaust fan for at least 15 minutes after cooking or washing dishes. Leave the shower door or curtain slightly open when the RV is parked to encourage natural cross-ventilation. If you are storing clothes or linens, consider using breathable canvas storage bags rather than airtight plastic bins, which can trap ambient moisture inside.

Additionally, perform a monthly inspection of the converted space. Remove your storage bins, check the shower pan for any condensation or leaks from the plumbing behind the walls, and wipe down the surfaces with a mild vinegar solution to kill any dormant mold spores. Taking these proactive steps ensures your extra storage space remains clean, dry, and odor-free throughout your travels.

Converting your underutilized RV shower into a highly organized storage hub is an incredibly practical way to unlock hidden square footage in a small camper. By choosing damage-free, flexible systems like tension rods, slim rolling carts, and reliable moisture-control tools, you can easily customize the space to fit your changing travel needs. With a little planning and the right gear, your camper will feel more spacious, organized, and ready for the open road.
