Class B Bathrooms: Wet Bath, Dry Bath, and What You Actually Get

Why there is no dry bath on this list

A dry bath needs two separate spaces where a wet bath needs one: a shower that keeps its water to itself, and a toilet space outside it. In a van that also has to hold a bed, a galley and belted seating inside a cargo van shell, every verified maker in this pool spends that floor space once, on a combined wet bath, or does not spend it on a fixed bathroom at all. That is why the honest headline of this article is an absence. If a listing or a roundup calls a Class B bathroom dry, check where the toilet sits: if the toilet stands in the shower space, it is a wet bath, whatever the headline calls it.

Group one: enclosed wet bath with a plumbed flush toilet

Five verified models give you the conventional RV bathroom in miniature on every floor plan: an enclosed wet bath, a sink or shower fittings as listed, and a flush toilet plumbed to a holding tank that empties at a dump station.

Airstream Interstate and Grech Terreno: the macerator pair

The Airstream Interstate 24GLX has what Airstream calls a space-saving wet bath with a shower and a foot-flush toilet running to an 11 gallon waste tank, emptied by a macerator pump system with electric retract, per Airstream specification page. There is no cassette toilet. The Grech Terreno has a wet bath with a window, a sink and a shower, and a porcelain toilet with a macerator pump running to a 13 gallon black tank, per Grech. On both vans the macerator is the detail to notice: the toilet is plumbed and fixed, and emptying is a pump and hose job at a dump point, not a carry-out container.

Coachmen Galleria and Nova: wet bath on every floor plan

The Coachmen Galleria has a wet bath with a sink and a shower and a porcelain flush toilet running to a black tank on every floor plan, per Coachmen: 19 gallons on the 24A, 24 on the 24FL, 12 on the 24Q and 26 on the 24RB. The Coachmen Nova has a wet bath with a fiberglass shower and a flush toilet running to a black tank on every floor plan: 19 gallons on the 20C and 20D and 10 gallons on the 20RB. Neither Coachmen model offers a cassette on any floor plan, which splits the ProMaster and Sprinter pools cleanly against the Winnebago and Thor entries below.

Winnebago Travato: wet bath, flush toilet, no cassette

The Winnebago Travato ledger line for its bathroom is the bare words wet bath, so the toilet was re-verified in Winnebago 2026 Travato brochure on October 24, 2026 before this article was written. The brochure publishes a full wet bath and black holding tanks of 11 gallons on the 59G and 12 gallons on the 59K and 59KL, and publishes no cassette capacity for the model. Our ledger records the Travato toilet as a foot pedal flush toilet running to that black tank. The Travato does not use a cassette toilet. Its Sprinter sibling, the Winnebago Revel, is the Winnebago with the cassette, which is one of the clearest differences between the two vans.

Thor Sequence and Tellaro, 20L and 20Y: the flush half of a split line

The Thor Sequence and the Thor Tellaro belong in this group on two of their three floor plans. On the 20L and the 20Y, each line has an enclosed wet bath with a gravity-flush toilet running to a black tank of 13.5 gallons on the 20L and 14 gallons on the 20Y, per Thor floor plan specifications. The third floor plan, the 20U, is in the cassette group below, and that split is the single most blurred bathroom fact in this segment: the model name alone does not tell you which toilet a specific van has.

Group two: enclosed wet bath with a fixed cassette

Two Winnebago models, and one floor plan in each Thor line, keep the enclosed wet bath and change how waste leaves it: a sealed cassette that slides out and empties through a pour spout, at a dump station or into a regular toilet, with no sewer hose and no black tank.

Winnebago Solis: cassette on both floor plans

The Winnebago Solis has an enclosed wet bath with a swiveling cassette toilet and a 5 gallon cassette on both floor plans, the 59P and the 59PX, per Winnebago Solis brochure, and there is no black water tank at all. The Solis is also the only van in this pool rated at four as a standard configuration, covered in our sleeps four guide, so it is the one entry here that combines an enclosed bathroom, a cassette and sleeping for four in the same van.

Winnebago Revel: the one published wet bath size in the pool

The Winnebago Revel bathroom in our ledger was manufacturer-only, so it was re-verified on Winnebago own Revel page on October 24, 2026 before this article was written. That page still publishes a shower with wall surround, a wet bath at 31 inches by 26 inches, a swiveling cassette toilet and a cassette toilet capacity of 5 gallons. The Revel is the only verified model whose maker publishes a wet bath size in our ledger, which is why it is the only dimension in this article. The cassette trade itself, capacity against emptying flexibility, is worked through in our cassette toilet guide.

Thor Sequence and Tellaro, 20U: the cassette floor plan

On the Thor Sequence and the Thor Tellaro, only the 20U has a cassette toilet, with a 4.75 gallon cassette in its enclosed wet bath. Thor floor plan specification pages list waste water at 4.75 gallons on the 20U against the 13.5 and 14 gallon black tanks on the other floor plans, and Thor Tellaro brochure states the split outright. If a dealer advertises a Sequence or a Tellaro as a cassette toilet van, ask which floor plan is on the lot, because two of the three are not.

Group three: no fixed bath, stowable shower and portable toilet

Three verified models spend the bathroom floor space on living and gear space instead. None of the three has a fixed wet bath or a black tank. What each has is a shower system that stows away, a portable toilet, and an exterior shower.

Storyteller MODE: Halo Shower and a 2.6 gallon portable

The Storyteller Overland MODE, in Classic MODE OG form, has no fixed wet bath. Storyteller fits a Halo Shower system, a portable cassette toilet with 2.6 gallons of capacity and an exterior shower, per Storyteller specifications. The trade is stated plainly in the rest of the MODE record: the floor space a fixed bathroom would take goes to the living layout, and the van carries its 37 gallon fresh tank inside the cabin, the largest in this pool, paired in our fresh water guide. A buyer who needs an enclosed bathroom should cross this van off early. A buyer who showers outside or at facilities is not paying for a room they will not use.

Remote Vans Aegis and Friday: Cyber Shower and a toilet in the shower box

The Remote Vans Aegis has no fixed wet bath: a Cyber Shower recirculating stowable shower system, a portable Thetford cassette toilet stored in the shower box, and an exterior shower, per Remote Vans. Remote Vans describes the Cyber Shower as recirculating and claims showers of 10 or more minutes on under 3.5 gallons, which is the manufacturer claim recorded in our ledger. The Remote Vans Friday makes the same trade with the same Cyber Shower pattern and what Remote Vans calls a portable cartridge toilet, plus an exterior shower. Neither van has a black tank. Our Remote Vans review covers the rest of that bathroom trade in detail.

Bathroom dimensions: one published size, and the missing ones

Buyers ask for wet bath dimensions more than almost any other bathroom figure, and the verified record is thin. The Revel at 31 inches by 26 inches, re-verified on Winnebago own page on October 24, 2026, is the only wet bath size in our ledger. Coachmen publishes no wet bath dimensions in its specification tables for the Galleria or the Nova. Winnebago Travato brochure floor plan diagrams state no consistent figure for every floor plan, so no Travato size is quoted here. Thor Tellaro brochure graphics carry a 48 inch by 26 inch wet bath figure that cannot be attributed to a specific floor plan from the published material, so this article does not use it. Where a maker publishes no size, this article reports that absence rather than filling it from a dealer page. If the size of the room decides your purchase, measure the specific van, because the published record will not settle it for any model but the Revel.

Models that are not in this table, and why

The Transit-based factory models in our market index, the Coachmen Beyond, the Entegra Coach Expanse, the Thor Palladium and the Forest River Lucent covered in our Transit guide, carry no bathroom attribute in our verified ledger, so no bathroom claim is made for them here. Custom builders such as Sportsmobile build bathrooms to each client layout, so there is no single factory bathroom to tabulate. If the bathroom decides your purchase on any of those vans, verify the bath type and the toilet type on the manufacturer page for the specific model and floor plan before you rely on a listing description.

How to choose a Class B bathroom

Start with the routine you will actually live with. If you want a private enclosed room and a plumbed toilet that works like the one at home, your pool is group one: the Interstate, the Terreno, the Galleria, the Nova and the Travato, plus the Thor 20L and 20Y. If you want that same enclosed room with waste you can empty at a wider range of places, your pool is group two: the Solis, the Revel and the Thor 20U floor plans. If living space matters more than an enclosed bathroom, and you are content to set a shower up and stow it again, your pool is group three: the MODE, the Aegis and the Friday. And if a separate dry toilet space is a hard requirement, no van in the verified factory pool meets it, and that is worth knowing before you shop, not after. Run your short list through the comparison tool, take the match quiz to weigh the bathroom against sleeping, water and budget, and browse the full market index for the listed models outside the verified table.
