8.5×24 Enclosed Race Trailer for Sale | Hunt’s Custom Cargo
$12,400.00
Most people don’t think about the bathroom until they’re two days into an event and booking a hotel room just to shower. Hunt’s builds enclosed trailers with bathrooms for buyers who’ve had that conversation with themselves — race teams, toy hauler owners, and anyone running a multi-day operation who wants to stay on-site and stay comfortable. Browse the inventory below or design your bathroom trailer build to your exact spec.
If you can dream it, we can build it. The right bathroom configuration starts with your size, your use — race hauler, toy hauler, or custom enclosed build — and how far you want to take the fit-out. Don’t settle for a spec that doesn’t match your needs. Work directly with our team to build an enclosed trailer with a bathroom exactly where you want it.
Yes — almost any enclosed trailer can be built with a bathroom. It ranges from a simple cassette toilet tucked into the nose of a race trailer to a full wet bath with a hot shower in a toy hauler or living-quarters build. The bathroom is added during the build, not bolted on after: we frame a sealed compartment, plumb a fresh-water and grey-water tank, and finish it with the fixtures you pick. A bathroom package typically adds a few hundred pounds of loaded weight and a build cost that depends entirely on how far you go — a portable toilet enclosure sits at one end, a plumbed wet bath with a water heater at the other.
Because every unit is made to order, the bathroom option isn’t limited to one model. The most common builds are:
Two things change when you add a bathroom: the price and the loaded weight. Weight is straightforward — water is heavy (about 8.3 lb per gallon), so a 20-gallon fresh tank alone adds roughly 170 lb full, before fixtures and framing. Cost depends on the tier you choose, from a basic toilet enclosure to a fully plumbed wet bath. We break the numbers down in how much it costs to add a bathroom to an enclosed trailer.
A trailer bathroom runs on its own water system: a fresh-water tank feeds a 12-volt pump, the pump pushes water to the toilet and shower, and waste drops to a cassette or a plumbed grey/black tank. Add a small water heater and you have hot showers off-grid. The full walk-through is in trailer bathroom plumbing & shower setup.

Hunt’s Custom Cargo offers several financing options on trailer purchases. You can learn more about each type by choosing an options below.
Factory-built is almost always the better option on a new build. The bathroom is framed, plumbed, and weight-balanced correctly the first time — and it’s covered by the warranty. DIY bathroom kits are cheaper upfront but often harder to install correctly and can void the warranty on a new trailer. See how the plumbing works and build it in from the start.
