Convert a Cargo Van into a Mobile Pet Grooming Salon
Cargo Van, Sprinter, or Step Van → Mobile Pet Grooming Salon
Mobile grooming is the fastest-growing corner of a pet-care market that keeps compounding: the mobile pet grooming service market was about $1.71 billion in 2025 and is projected at $1.87 billion in 2026 on its way to $3.10 billion by 2034, with the mobile segment specifically expanding 12 to 15 percent a year as owners pay a premium for at-home service. A single well-built van can bill $75,000 to $200,000 a year at $50 to $100 per appointment with no storefront rent. But a grooming van is not a camper with a tub in it — it is a self-contained plumbing, electrical, and climate-control system carrying live animals, and the two things that sink amateur builds are payload weight and a generator that cannot run the dryer and the air conditioning at the same time.

Steps
Choose the Vehicle by Payload, Not by Floor Space
Every decision in this build traces back to weight. Water weighs 8.34 pounds per gallon, so a 50-gallon fresh tank plus a 30-gallon gray tank is more than 650 pounds of liquid alone before you add a hot water heater, a generator, a steel tub, cabinetry, equipment, and a groomer and a dog standing in the back. It is genuinely easy to build a van that is illegal and unsafe to drive. Start by reading the door-jamb sticker for GVWR and the front and rear GAWR, weigh the empty van at a truck scale, and subtract to get your real payload — then budget it line by line and keep 15 percent in reserve. In practice that pushes most builders to a high-roof, extended-length three-quarter-ton or one-ton van (a Sprinter 2500/3500, Transit 350, or ProMaster 3500) or a step van, and away from the half-ton cargo vans that look affordable on the lot. Interior height is the other hard requirement: you will stand and bend over a tub for eight hours a day, and a low-roof van guarantees back injuries and a short career. Prefer a diesel or a heavy-duty gas drivetrain if you will run hills or a heavy build, check that the chassis can accept the alternator or generator you plan on, and inspect any used van for rust in the floor pan and rocker panels, because you are about to introduce a permanent water source into that vehicle. Buy the van before you design the layout, and design around its actual measured interior.

Handle the Business, Licensing, and Insurance Groundwork First
There is no national pet groomer license in the United States, which misleads a lot of new operators into thinking the business is unregulated. The requirements are real, they are just local. Form an LLC and get an EIN, then obtain a general business license in every municipality you intend to operate in — mobile businesses frequently need a separate license or a mobile-vendor permit in each city on the route, not just your home city. Check three specific things that catch mobile groomers. First, water and waste: many jurisdictions regulate where gray water may be discharged, and dumping soapy, hair-laden wash water into a storm drain or onto the street is an environmental violation almost everywhere. Plan for a holding tank and a legal disposal point — your own sanitary sewer cleanout, an RV dump station, or a commercial facility — and keep records. Second, zoning and parking: some residential districts restrict commercial vehicles operating curbside or running a generator, and HOAs frequently do. Third, insurance, which is the one that ends businesses. You need commercial auto — a personal auto policy will not cover business use and will deny the claim — plus general liability, and animal bailee or professional liability coverage for injury to a pet in your care, which general liability specifically excludes. Add workers' compensation if you hire, and inland marine or equipment coverage for the build-out itself, since it is worth more than the van. Sort all of this before the build so your insurer can quote the finished vehicle.

Design the Floor Plan and the Weight Distribution Together
The proven mobile grooming layout is a straight-line workflow: a rear or side entry with a ramp or steps for dogs who cannot be lifted, then a bathing station with the tub, then a grooming table, with storage and the mechanical bay separated from the wet zone. Put the heavy items — fresh water tank, gray tank, hot water heater, batteries, and generator — low and as close to over or ahead of the rear axle as the chassis allows, and split fresh and gray so the load does not migrate rearward as the day goes on. Keep the wet zone genuinely wet: a welded or seamless one-piece pan under the tub, coved seams, and a floor that drains toward it so nothing wicks into the subfloor. Everything else needs to be reachable from where the groomer stands with two hands on a dog, which is the single test most homemade layouts fail. Measure the working triangle for real — tub lip height around 30 inches so you are not lifting from the floor, table height set to the groomer, and clearance to swing a 60-pound dog around without hitting a cabinet corner. Draw it full scale on the shop floor in tape and walk it before you cut anything. Finally, plan the service access now: pumps fail, heaters fail, and a beautiful build with a water pump buried behind screwed-down cabinetry costs you a full day of revenue every time it needs a five-minute fix.

Build the Water System — Fresh, Hot, and Gray
The full water system typically runs $1,200 to $3,500 depending on tank size and component grade, and it is the heart of the vehicle. Size the fresh tank to the day you actually plan to work: 40 to 60 gallons covers roughly six to eight average dogs, and running out mid-route means driving to a fill point and losing an appointment. Use potable-rated tanks with baffles to stop water from sloshing and destabilizing the van, strap them down to structural mounts rather than to plywood, and plumb a fill port and a vent on the exterior. A 12-volt demand pump with an accumulator gives steady pressure without cycling, and a sediment and carbon filter on the inlet protects the heater and improves the wash. For hot water you have two paths: a small tank-style RV water heater, which is simple and reliable but limited in capacity and slow to recover, or an on-demand propane or diesel unit, which gives essentially unlimited hot water but adds a fuel system, combustion venting, and a carbon monoxide detector as a non-negotiable safety item. Whichever you choose, size the gray tank to match or exceed the fresh tank so you never have to choose between finishing a dog and finding a dump station, and fit the tub drain with a real hair trap because dog coat will clog a gray system faster than anything else on the vehicle. Winterize if you work in freezing climates: heated tanks and heat tape on lines, or a documented drain-down routine at the end of every cold day. Use PEX with proper crimp fittings, pressure-test the whole system to well above operating pressure, and leave it under test overnight before you close up any wall.

Size and Install the Power System Honestly
This is where most self-built vans come up short, because groomers underestimate simultaneous load. A high-velocity force dryer draws a lot of current, and you will frequently be running the dryer, the water heater, the lights, the vacuum, and the air conditioning at the same time on a hot afternoon. A portable inverter generator in the 2,000 to 3,500 watt class — a Honda EU2200i or Generac GP3500iO, both common starter choices — will run a modest single-dryer setup but will trip the moment you add climate control. Full-service mobile grooming units generally run a commercial generator in the 7,000 to 8,000 watt range, such as a Cummins Onan 7000 delivering about 58 amps or an 8000 diesel delivering roughly 66 amps, permanently mounted with its own fuel supply and an exhaust routed well away from the intake and the working area. Budget $3,500 to $7,000 for the generator and electrical package. Build an actual load table before you buy: list every device, its running watts and its surge watts, and the worst realistic combination, then size to that with headroom. A lithium battery bank plus a pure sine inverter is an increasingly popular hybrid — the batteries run lights, pump, and fans silently so the generator only fires for dryers and air conditioning, which cuts noise complaints, fuel burn, and hours on the generator considerably, and quiet operation is a genuine selling point in residential driveways. Have the AC side wired by a qualified electrician: you are combining 120-volt power with a water-filled steel tub, so GFCI protection on every wet-zone circuit, a proper bonding and grounding scheme, marine-grade tinned wire, and sealed connections are safety requirements, not upgrades.

Install Climate Control and Ventilation — This Is a Life-Safety System
Treat heating, cooling, and air movement as the most important safety system in the van, because a dog left in an uncooled vehicle can die in minutes and it is the fastest way to end a business. Budget $3,000 to $5,000 for the climate package. You need real air conditioning that works with the engine off, which means a rooftop RV unit or a 12-volt DC mini-split running off the battery bank, sized to a metal box sitting in full sun with a heat-producing dryer inside it. Add a heater for winter work — either a diesel or propane air heater or an electric unit — since a wet dog in a cold van is just as much a welfare problem. Insulate the walls, roof, and floor properly with closed-cell foam or equivalent, including a thermal break at the metal ribs, both to hold conditioned air and to control condensation, which will otherwise rust the van from the inside. Ventilation does separate work: roof vent fans and an exhaust path pull out the enormous volume of hair, dander, and shampoo aerosol a dryer throws into the air, protecting the groomer's lungs as much as the dog's. Fit a temperature monitor with a remote alarm to your phone, plus a carbon monoxide detector if you run any combustion appliance or generator, and a smoke detector and fire extinguisher. Many operators also add a second independent temperature alarm — redundancy here is cheap, and the failure mode is not recoverable.

Fit Out the Working Interior: Tub, Table, Dryers, and Safety
Now build the salon. A complete professional equipment package runs roughly $8,000 to $12,000. The tub is the centerpiece: a stainless steel walk-in or side-entry tub sized for the largest dog you will accept, set at a working height so you are not bending to the floor, with a non-slip surface, a removable ramp or door for seniors and large breeds, a handheld sprayer on a long hose, and a recirculating or high-velocity bathing system if you want to cut bath times. A hydraulic or electric grooming table runs $800 to $2,000 and pays for itself in avoided back injuries; bathing systems run $1,500 to $3,500; dryers, clippers, shears, and hand tools add $2,000 to $4,000. Mount everything for road travel — the van is a moving vehicle and an unsecured dryer becomes a projectile — using through-bolted brackets into structure, latching cabinet doors, and drawer slides that lock. Use marine-grade non-slip flooring with coved edges up the walls so the wet zone can be hosed and squeegeed, and choose finishes that survive daily disinfection. Light it far better than you think you need: high-CRI LED lighting at the tub and table is the difference between a good haircut and a callback. Then the animal-safety layer, which is what separates a professional build from a hobby one: grooming arms with quick-release loops and a no-fly harness, a latched entry so a startled dog cannot bolt into traffic, kennel or holding space if you handle more than one dog, sharp-tool storage out of reach, a first-aid kit for both species, and a hair-containment plan so the vacuum and drains do not clog daily.

Weigh It, Inspect It, and Launch the Route
Before the first client, take the finished van fully loaded — full fresh tank, full fuel, all equipment, and you in the driver seat — back to a certified scale and confirm you are under GVWR and under both axle ratings. If you are over, fix it now by downsizing the fresh tank or relocating mass, because an overloaded van brakes badly, wears out tires and suspension, and voids insurance claims. Then run a shakedown: pressure-test the water system again under road vibration, groom a few friends' dogs for free to find every reach and workflow problem, and verify the generator holds up with dryer and air conditioning running together on the hottest day you can find. On the business side, price for the model rather than copying a storefront: mobile appointments realistically bill $50 to $100 and up depending on breed, coat, and market, and the economics come from route density, not from volume — cluster appointments by neighborhood so you are not burning an hour and a tank of fuel between dogs, and build recurring 4-, 6-, or 8-week standing appointments, which are what turn this into predictable revenue. Use grooming-specific booking software with online scheduling, deposits, automated reminders to cut no-shows, and route optimization. Market where pet owners already are: local Facebook groups and Nextdoor, veterinary and pet-store referral partnerships, and the van itself, which is a rolling billboard parked in a different driveway every hour and is the single best marketing asset the business will ever own. Wrap it well, keep it spotless, and track fuel, water, supplies, and maintenance per appointment from day one so you know what a dog actually costs you to groom.

Permits
Business License and Mobile Vendor Permits
Form the entity and obtain a general business license, then check every municipality on your route — mobile businesses commonly need a separate mobile-vendor or itinerant-business permit in each city they operate in, not only where they are based. Some jurisdictions also require a local animal-establishment or kennel-type permit for grooming, and a few states license groomers directly. There is no federal pet grooming license, so the entire requirement set is state and local.
$600
Wastewater Discharge / Gray Water Disposal Approval
Soapy, hair-laden wash water cannot legally be discharged to a storm drain, a street, or a client's yard in most jurisdictions. You need a holding tank and an approved disposal point — a sanitary sewer cleanout, an RV dump station, or a commercial dump facility — and some cities require registration or a discharge permit plus disposal recordkeeping. Confirm the rule in each city on your route before you operate there.
$350
Commercial Vehicle Registration and Weight Compliance
The finished van must be registered for commercial use and must operate under its GVWR and both axle ratings when fully loaded with water, fuel, equipment, and occupants. Weigh the completed build at a certified scale. Depending on state and final weight, commercial plates, a DOT number, or additional inspection requirements may apply, and an overloaded vehicle is grounds for an insurance denial after an accident.
$500
Insurance Package: Commercial Auto, General Liability, Animal Bailee
A personal auto policy will not cover business use and the claim will be denied, so commercial auto is mandatory. Add general liability for third-party injury and property damage, and animal bailee or professional liability for injury to a pet in your care — a coverage general liability specifically excludes. Include equipment or inland marine coverage for the build-out, and workers' compensation once you hire. Quote the finished vehicle, not the empty van.
