That mishap taught me to test ideas with photo-realistic mockups before touching a wall. Tiny rooms really do spark big creativity, and today I’m sharing five RV bathroom decorating ideas I actually use with clients—and in my own rigs.Make light, height, and mirrors your best friendsI lean on soft, matte off-whites for walls and keep the ceiling a shade lighter to fake height. Vertical clues—tall grout lines, slim stripes, even a long mirror—stretch the room visually. An acrylic mirrored cabinet doubles daylight without the weight of glass, but measure swing clearances so you don’t elbow it mid-shower.LED strips tucked under a floating shelf create a glow without glare. Just remember in an RV, condensation is a thing—choose IP65-rated LEDs and keep drivers out of splash zones.save pinStick-on surfaces that survive steam and swayPeel-and-stick vinyl tile or SPC planks give you pattern without bulk, and FRP panels are my go-to behind sinks because they wipe clean. I scuff glossy factory walls lightly, prime with a bonding primer, and use an adhesive rated for moisture; that prep stops edges from lifting on hot days.Teak shower mats look spa-ish and dry fast, but oil them so they don’t grey too quickly. And if you’re tempted by cement-look paints, choose a water-resistant topcoat so splashes don’t leave polka dots.save pinSlim storage that doesn’t bruise your elbowsI love an 18-inch rail with S-hooks for razors, loofahs, and a collapsible cup. Magnetic strips tame tweezers and nail clippers, and shallow corner shelves beat bulky caddies. With compact bathroom layouts, every inch matters—keep anything mounted under 3 inches deep so you don’t bump it.Adhesive-backed options avoid drilling; in humid areas, I use VHB tape plus a tiny bead of clear sealant at the perimeter. It’s shockingly sturdy, but give it 24 hours to cure before loading.save pinA controlled pop of pattern and colorPick one “hero” moment—a single band of mosaic behind the faucet, or a bold, peel-and-stick botanical on just the upper third of a wall. The rest stays tonal: sand, oat, or pale grey with matching towels keeps it calm.Textures carry color farther in small spaces. Waffle towels and a ribbed shower curtain add depth without clutter, and they dry quicker—win-win when humidity spikes.save pinUpgrade fixtures, warm the light, and tame moistureA high-efficiency showerhead saves water and feels better than the stock sprayer; pair it with a slim faucet aerator for a smoother stream. I swap cool bluish bulbs for 2700–3000K LEDs—skin looks healthier and the room reads cozy. Before buying, do a bit of quick space mapping to confirm the faucet throw won’t splash the door.Moisture is the silent decor killer. I run the vent fan during and 15 minutes after showers, hang a microfiber towel set for faster drying, and stash two desiccant bags inside the vanity. It’s unsexy, but it keeps sealants, paint, and decals crisp.save pinFAQWhat colors make a small RV bathroom feel bigger?I use warm, light neutrals (soft white, oat, pale grey) and keep contrast subtle. A single darker accent line adds interest without chopping up the space visually.How do I prevent mold and mildew in an RV bathroom?Vent during and at least 15 minutes after showers, squeegee walls, and keep a desiccant bag under the sink. The U.S. EPA notes that controlling moisture and improving ventilation is key to preventing mold (U.S. EPA—Mold and Moisture: https://www.epa.gov/mold).Can peel-and-stick tiles handle RV moisture and movement?Yes—if you scuff, prime with a bonding primer, and use moisture-rated adhesives. Avoid installing near direct heat, and roll seams firmly so edges don’t lift.What lighting is safe in an RV bathroom?Choose IP65-rated LED strips or damp-rated fixtures, and warm them to 2700–3000K for flattering light. Keep drivers and connections out of splash zones and respect 12V/120V wiring standards.How do I add storage without drilling into thin walls?Use adhesive rails, S-hooks, magnetic strips, and door-hung organizers. High-bond tapes plus a bead of clear sealant make surprisingly sturdy mounts.Are real plants a bad idea in an RV bathroom?Not at all—choose low-light, humidity-friendly options like pothos or air plants, and secure pots with putty. If travel is bumpy, go faux for zero maintenance.How can I make the shower feel larger?Go clear on curtains or screens, use vertical tile lines, and add a teak mat to visually extend the floor. A handheld showerhead also helps you angle water away from tight corners.What’s a realistic budget for a mini refresh?$150–$500 covers stick-on surfaces, new hardware, towels, and lighting. Add another $100–$200 if you’re upgrading the showerhead or faucet.save pinStart for FREEPlease check with customer service before testing new feature.Free Room PlannerDesign your dream room online for free with the powerful room designer toolStart for FREE
