If you've been researching pressure washing trailers, you've probably noticed something frustrating: almost nobody publishes prices. "Call for a quote" is the industry standard, which makes it nearly impossible to budget before you're deep in a sales conversation.
We're going to do the opposite. We build pressure washing trailers here in Oregon City, Oregon, and ship them to washers all over the country — and before that, we ran our own pressure washing company for over a decade on trailers, box trucks, flatbeds, vans, and skids. So here are our real numbers, straight from our live catalog, and an honest breakdown of what moves the price up or down.
The short answer
In 2026, a professional pressure washing trailer costs anywhere from about $5,300 for a bare custom trailer platform (no equipment) to $31,000+ for a fully loaded hot water rig. Most washers buying a complete, turnkey cold water setup land in the $17,000–$27,500 range depending on size, machine, tanks, and reels.
Real prices from our shop
- Eagle Series dual axle trailer, bare — $5,319. The custom trailer platform only: dual axle, built to carry water weight safely. This is the route if you already own your machine, tanks, and reels and want a proper foundation under them. Add a ladder rack and you're at $6,061.
- The Portlandian mini trailer (5x8) — $16,999. Our compact single-axle build for washers who want something easy to tow, park, and maneuver in tight neighborhoods. Great starter rig — just know a mini isn't the platform for hauling large amounts of water.
- Custom enclosed 5x8 builds — around $20,000. Everything locked up and out of the weather, wrapped and rolling as a billboard.
- Dual axle soft wash setups (6.5x12) — around $23,000. Dedicated soft wash plumbing, larger tanks, room for the water capacity roof and house washing crews need.
- Eagle Series 6x10 complete setup — $24,700–$27,442. Our flagship turnkey cold water trailer: machine, buffer tank, reels, plumbing, all mounted, tested, and ready to wash the day you pick it up.
- Hot Eagle hot water trailer — $31,294. Everything above plus hot water, which opens up grease, gum, oil, and commercial flatwork that cold water can't touch — and lets you charge accordingly.
What actually drives the price
Two trailers can look similar in photos and be $10,000 apart. Here's where the money goes:
- Hot water vs. cold water. The single biggest jump. A hot box adds thousands, but it's the difference between residential house washing and being able to bid commercial flatwork, drive-thrus, and fleet contracts.
- Machine size (GPM). An 8 GPM machine costs meaningfully more than a 4 GPM — and it also pushes up the size of your buffer tank, hose, and plumbing to feed it.
- Water capacity and axles. Water weighs about 8.3 lbs per gallon. Carrying real water means a dual axle trailer, proper brakes, and a frame built for the load — this is where cheap builds cut corners and where used trailers most often hide problems.
- Reels, plumbing, and layout. Quality hose reels, stainless fittings, and plumbing that's laid out so you can actually work around the trailer all day. This is the stuff you don't notice in a photo and feel on every single job.
- Single vs. dual axle, open vs. enclosed. Enclosed adds cost but buys security, weather protection, and one winterizing advantage: you can run a small Wi-Fi controlled heater inside during freezes instead of garaging the rig.
We might not be the cheapest — here's what to look at before you buy cheaper
Let's be upfront: if you shop around, you'll probably find trailers priced below ours. We're not going to pretend otherwise, and we're not going to tell you every cheaper option is junk — some aren't.
But the one thing you need to be aware of when researching a pressure washing trailer in 2026 is how it's built. Price tells you almost nothing; the build tells you everything. Two trailers can carry the same machine and the same tank and be worlds apart in what they'll cost you over five years. Here's the checklist we'd hand a friend shopping any builder — including us.
Start with the trailer platform itself
- Is it completely custom built? Or is it equipment dropped onto a stock landscape trailer? A purpose-built platform is designed around the water weight, the layout, and the workflow from the first weld.
- Is the framing upgraded — and is the ladder rack a real rack built into the framing, or an accessory bolted on top?
- Is the wood sealed? A wash trailer lives its whole life soaking wet. Unsealed decking rots out from under the equipment.
- Upgraded axles and full-size 15" tires? Loaded water weight eats undersized axles and small tires alive. This is one of the most common corners cut on budget builds.
- Are the lights all LED? Small detail, but incandescent trailer lights on a rig that gets sprayed daily are a recurring headache.
- Is there any warranty on the trailer? If the builder won't stand behind the frame, that tells you what they think of it.
Then get into the actual build quality
- Tank strapping. Some trailers ship with really cheap tank strapping systems — and a shifting tank full of water is not a small problem.
- Fittings and hardware. Is the builder using all stainless? On our builds, every fitting and every bolt is stainless or high-quality poly Banjo. Anything less starts corroding the first season.
- Wiring. Is it upgraded USA-made marine-grade double-insulated wiring? A pressure washing trailer is a wet, vibrating environment — automotive-grade wiring in split loom doesn't survive it.
- The soft wash system. Is it a designed system, or something cheap thrown together to check a box on the spec sheet?
- The pressure washer. Is it an off-the-shelf cheap machine? Is it pull start or electric start? You'll feel that answer 30 times a day.
- The plumbing. A lot of builders use cheap plumbing — it's invisible in photos and it's where "great deal" trailers bleed money in repairs. We use Banjo throughout.
- The hose reels. Cheap reels with steel manifolds rust from the inside out. We run full-frame aluminum reels with 316 stainless steel manifolds.
We'll be straight with you: most of the things on this list are things we do that a lot of other trailers on the market don't — that's a big part of why we're not the cheapest. But the list is still the list, whoever you buy from. Every one of these choices affects long-term reliability, and cutting corners on the front side only costs you on the backside if you don't do your research and buy cheap.
The costs nobody mentions
Budget past the trailer itself: a tow vehicle that can legally and safely pull a loaded rig, trailer registration and insurance, and somewhere secure to park it at night. If you don't have secure parking, solve that before you buy — or consider a truck skid instead. We covered that whole decision in our skid vs. trailer vs. van guide.
Is a cheap used trailer the better math?
Sometimes — but be honest about what you're buying. A $10,000 used rig with a tired machine, undersized axles, and mystery plumbing can cost you more in downtime than the savings, and downtime in this business is cancelled jobs. If you go used, have someone who knows pumps and plumbing look at it first. (We see the aftermath come through our shop regularly.)
Making the number work
Every trailer that leaves our shop comes with free hands-on training and a lifetime frame warranty, and we offer financing — on a working rig, a monthly payment is often covered by the first couple of jobs each month.
