5 Small-Space Ideas for RV Trailers with 2 Bathrooms: Smart, real-world tips from a decade-long interior designer to make dual-bathroom RVs feel roomy and luxe

I once had a client who insisted their tiny RV needed a full bathtub and a bidet in separate bathrooms — I almost cried, then redesigned both spaces to actually work. Small spaces force you to be creative: the trick isn’t cramming features in, it’s choosing the right ones and arranging them cleverly. In this piece I’ll share 5 practical design inspirations I’ve used on RV trailers with 2 bathrooms, based on real projects and the occasional client curveball.

1. Split wet and dry zones for better flow

In one of my favorite conversions, I separated the shower into a compact wet room and kept the sink/toilet in a dry zone across the hall. That way two people can get ready at once without stepping over each other. The upside is clear functionality and faster morning routines; the trade-off is you need clever venting and moisture control, which can add a little complexity.

2. Use sliding doors and pocket solutions

Traditional swing doors eat precious swing radius. I specify barn-style sliding doors or pocket doors to reclaim floor space — it’s an inexpensive swap that instantly widens circulation. Be mindful of hardware weight and track noise; choose soft-close systems for a long-term quiet ride.

3. Stack fixtures and smart storage vertically

When floor area is tight, my go-to is vertical thinking: stack a shallow cabinet above the toilet, mount mirrored medicine cabinets, and use recessed niches in shower walls. I once used a tall, narrow linen tower between two bathrooms to share towels — great storage without footprint bloat. The downside is you may need custom joinery to maximize awkward gaps.

4. Choose compact, multi-function fixtures

Dual-flush toilets, corner sinks, and fold-down vanities are lifesavers. In one RV I installed a fold-out counter that doubles as a laundry folding station next to a shower — functional and surprisingly elegant. The trade-off: multi-function pieces sometimes cost more upfront but repay comfort and usability over time.

5. Prioritize ventilation and odor control

With two bathrooms in close quarters, good ventilation makes the space feel fresh and upscale. I always specify quiet, high-capacity vents and consider small inline fans for longer ducts. It’s an often overlooked upgrade that prevents mildew and keeps fabrics happier — you’ll thank me on humid road trips.

Tips 1:

If you want to visualize different layouts quickly, I often mock up options using a room planner to test door swings and storage placements before committing to carpentry. For shared storage ideas, measure every gap — that skinny 6" void is often a perfect spice or cleaning supply niche.

FAQ

Q: What’s the minimum RV size for two bathrooms? A: Practically, you should aim for at least a 30–35 foot trailer to accommodate two functional bathrooms without extreme compromises. Smaller trailers can work but require very compact fixtures and careful planning.

Q: Are two bathrooms worth the space trade-off? A: For families or frequent guests, they’re a huge convenience and can increase resale appeal; for solo travelers, it may be unnecessary extra weight and cost.

Q: How do I control moisture between two bathrooms? A: Use dedicated exhaust fans with backdraft dampers, waterproof finishes, and consider a moisture-resistant paint or tile to minimize mold risk.

Q: Can I install standard home fixtures in an RV bathroom? A: Some can be used, but you’ll often prefer lightweight, RV-specific fixtures designed for limited water and power capacity.

Q: What’s a budget-friendly upgrade that makes a big impact? A: Swapping swing doors for sliding doors and adding a mirrored cabinet can both improve function and perceived space with modest cost.

Q: How do I plan plumbing between two bathrooms efficiently? A: Grouping bathrooms back-to-back or near the RV’s main waste stack reduces plumbing runs and complexity.

Q: Are there accessible solutions for RV bathrooms? A: Yes — low-threshold showers, grab bars, and fold-down seats can be integrated; consult ADA guidelines and RV-specific vendors for compact compliance options.

Q: Where can I find reliable layout tools to test ideas? A: For precise, user-friendly planning, Coohom’s room planner offers quick layout mockups and 3D visualization (source: Coohom case study).
