A 13-foot trailer with a working shower and toilet sounds impossible, but it’s real, and it’s smaller than most people expect.
Anyone hunting for the smallest RV with a shower and toilet usually runs into two different answers, not one clear winner.
The split comes down to towing versus driving, and each path has its own size floor and bathroom style.
Stick around, because the difference between a 13-foot trailer and a 19-foot campervan changes more than you’d think.
What’s the Smallest RV with a Shower and Toilet?
If you’re searching for the smallest RV with a shower and toilet, the honest answer is that there are two winners, not one.
It depends on whether you want something you tow or something you drive.
For towables, the Scamp 13’ Deluxe takes the crown at just 13 feet long, with a full wet bath tucked inside.
For drivable campervans, the Airstream Interstate 19 is the smallest option, measuring 19 feet end to end.
That six-foot gap isn’t random. Towables don’t need an engine or a driver’s cab, so every inch can be devoted to living space.
Drivable RVs have to fit a chassis, engine bay, and cab first. That’s why their smallest RV with bathroom options starts closer to 17–19 feet, never much lower.
How Does a Wet Bath Fits a Shower and Toilet into 13 Feet?
A wet bath is a single sealed room where the shower, sink, and toilet share the same floor space. There’s no separate stall here.
The entire room is waterproofed, so everything gets wet once the shower runs, including the toilet and sink area around it.
A few design choices make this layout possible inside such a tight footprint, working together instead of standing alone:
- Single floor drain: Handles all runoff from the shower, sink, and surrounding surfaces in a single location, eliminating the need for multiple drain lines.
- Showerhead above the toilet: Skips the extra plumbing a separate stall would otherwise require, saving both space and material cost.
- Fully sealed walls: Let water spray freely without damaging anything behind the surfaces, since everything is built to get wet.
Together, these choices free up the space a dry shower stall would normally occupy within an already tight overall footprint.
I’ve climbed into a few of these wet baths myself, and the layout makes more sense once you’re standing inside it.
It feels small at first, but every inch is designed to pull double duty, with nothing wasted on separation walls. Even so, this setup has a real limit, and it shows up fast once trailers shrink past a certain point.
A wet bath only works if there’s enough floor space left for a person to turn around and dry off. That’s not a styling choice manufacturers are making to cut costs; it’s just basic physics at play here.
Below 13 feet, there’s barely room for a human body to move inside the compartment at all comfortably.
That’s the real reason you won’t find a usable smallest RV with a bathroom option much smaller than this, regardless of layout tricks.
Wet Bath vs. Dry Bath: What Changes as RVs Get Bigger
A wet bath combines the shower, sink, and toilet into a single space. A dry bath keeps the shower walled off from the rest of the room.
That separation requires extra floor space, which is why dry baths only start appearing once a trailer reaches about 16 to 20 feet in length.
Here’s how the two layouts actually compare once you put them side by side:
| Feature | Wet Bath | Dry Bath |
|---|---|---|
| Layout | Shower, sink, and toilet share one space | The shower is walled off separately |
| Typical RV length | Under 16 feet | 16–20 feet and up |
| Daily convenience | The toilet gets wet during showers | The toilet and sink stay dry |
| Space trade-off | Saves room for sleeping and storage | Uses up space that other areas would need |
It’s tempting to assume a dry bath is simply the better setup, but that’s not quite right.
A dry bath saves daily cleanup because the toilet stays dry after showers, but the extra space often reduces your sleeping area or available storage.
So it’s less about better and worse, and more about which trade-off fits how you actually plan to travel.
Smallest Towable Trailers With a Shower and Toilet
If towing is your plan, here are the smallest trailers worth considering, ranked from tiniest to slightly larger.
Each one fits a real bathroom inside, and a few pair especially well with smaller SUVs if towing weight is a concern.
- Scamp 13’ Deluxe: At just 13 feet, this fiberglass trailer has a wet bath and a loyal following among long-time RVers. It’s light enough for most midsize SUVs to tow comfortably.
- nuCamp TAB 320 S: A 15-foot teardrop-style trailer that hides a cassette toilet and shower inside a surprisingly tight cabin. Its low profile makes it easy to tow without a heavy-duty truck.
- Casita 16′ Deluxe Spirit: Slightly bigger at 16 feet, with a fully molded wet bath interior. It’s well known in the fiberglass trailer community for holding up well over years of use.
These three cover a solid range, from the absolute smallest option to something with a bit more breathing room inside.
If you’re working with a smaller tow vehicle, the Scamp and TAB are your safest bets for staying within weight limits.
Smallest Drivable Campervans With a Shower and Toilet
If you’d rather drive than tow, these self-contained campervans are the smallest options worth considering, starting with the Airstream Interstate 19 at 19 feet.
Drivable RVs sit a bit higher on the size scale than towables, and there’s a simple reason behind that gap.
Every drivable unit needs to fit an engine and driver’s cab somewhere, which eats into space a towable trailer doesn’t have to give up.
- Airstream Interstate 19: The smallest of the group at 19 feet, built on a nimble van chassis with a compact European-style wet bath inside.
- Winnebago Solis: Sits close behind at around 17 to 18 feet, often considered one of the smallest Class B vans with a full onboard bathroom.
- Winnebago Revel: Built on a rugged 4×4 chassis, favored by off-grid travelers, with a wet bath that holds up well outside paved campgrounds.
These three show how little room manufacturers actually have to work with once an engine bay is even in the equation.
Compared to towables, the floor here simply sits higher, no matter how clever or creative the interior layout gets.
Which Size Is Right for You?
Picking the right size comes down to matching your tow vehicle and travel style, not just chasing the smallest number.
Here’s how your priorities line up against the size brackets covered earlier:
| Your Situation | Best Size Bracket | What You Get |
|---|---|---|
| Midsize SUV, solo or couple | 13–15 feet, wet bath | Lightest tow weight, smallest footprint |
| Larger SUV or truck | 16 feet and up | Access to dry bath options |
| Want the smallest footprint possible | 13 feet | Wet bath, minimal standing room |
| Want more daily comfort | 16–19 feet | Separate shower, less sleeping/storage space |
The smallest option isn’t automatically the right one for every traveler or every trip. A smarter approach is sizing up only as far as your must-have features actually require, nothing more.
Conclusion
Finding the smallest RV with a shower and toilet really comes down to one choice: tow it or drive it yourself.
Towables can shrink down to 13 feet thanks to wet baths, while drivable vans need extra room for the engine.
The size that fits you best depends on your tow vehicle, your travel style, and how much comfort you actually need.

Frequently Asked Questions
What is the smallest RV with a shower and toilet?
The smallest towable option is the Scamp 13′ Deluxe, a 13-foot fiberglass trailer with a wet bath. The smallest drivable option is a Class B campervan, like the Airstream Interstate 19, which is around 19 feet long. Both fit a toilet, sink, and shower into a single compact wet bath compartment.
What is the difference between a wet bath and a dry bath?
A wet bath places the shower, sink, and toilet in a single sealed compartment, so the entire space gets wet when you shower. A dry bath physically separates the shower enclosure from the toilet and sink and is usually found in trailers around 16 to 20 feet long, since separation requires extra floor space.
What is the smallest caravan with a shower and toilet?
Among towable trailers, fiberglass models lead the smallest category. The Scamp 13′ Deluxe, at 13 feet, is generally considered the smallest hard-sided travel trailer with an onboard wet bath shower and toilet, though it requires accepting a compact, shared bathroom space.
What is the smallest RV I can buy with a bathroom?
It depends on whether you want towable or drivable. Towable trailers can go as small as 13 feet with a wet bath. Drivable campervans need extra length for the cab and engine, so their smallest practical size with a bathroom starts closer to 17–19 feet.
