Mobile Pet Grooming Van Conversion: Layout, Cost, and Water Systems
A practical 2026 guide to mobile pet grooming van conversions: real cost ranges, floor plan layouts, water and heating systems, electrical sizing, and build timelines.
A turnkey mobile pet grooming van conversion in 2026 runs roughly $28,000 to $65,000 in build cost on top of a $35,000 to $60,000 cargo van, so most owners land at $65,000 to $120,000 all in. Budget builds (used van, partial DIY) start near $45,000 total, while high-end rigs with hydraulic lifts and dual heating push past $130,000.
Those numbers cover the conversion work itself: the grooming tub and plumbing, fresh and gray water tanks, a water heater, electrical and battery bank, climate control, lighting, cabinetry, and the grooming table. At Vanaholic, we have built mobile service rigs across Southern California since 2014, and grooming vans are one of the trickiest because they pack plumbing, heating, and high electrical draw into a small box on wheels. This guide breaks down what actually drives the cost, how to lay out the interior, and how to size the water system so you do not run dry at the third dog of the day.
What does a mobile pet grooming van conversion cost in 2026?
The honest answer depends on three things: the van you start with, how much of the work you do yourself, and whether you want hot water and full climate control (you do, in Orange County summers and high-desert Inland Empire heat).
Here is a realistic 2026 breakdown for a professional shop-built conversion on a mid-size cargo van such as a Ford Transit 148 or RAM ProMaster 159.
| Build component | Budget | Mid-range | High-end |
|---|---|---|---|
| Grooming tub (stainless, with ramp) | $1,200 | $2,400 | $4,500 |
| Fresh + gray water tanks and plumbing | $1,800 | $3,200 | $5,500 |
| Water heater (propane or electric) | $700 | $1,500 | $2,800 |
| Electrical: battery bank, inverter, charging | $2,500 | $6,000 | $12,000 |
| Climate control (AC + heat) | $2,000 | $4,500 | $8,000 |
| Cabinetry, table, flooring, walls | $3,000 | $6,500 | $11,000 |
| Lighting and ventilation | $800 | $1,800 | $3,200 |
| Labor and install | $8,000 | $16,000 | $28,000 |
| Conversion subtotal | ~$20,000 | ~$42,000 | ~$75,000 |
Add the van itself. A clean used Transit or ProMaster with 60,000 to 100,000 miles runs $28,000 to $42,000 in 2026, while a new cargo van is $45,000 to $62,000 before upfit. A fully financed new rig with a mid-range build typically pencils out around $95,000 to $110,000.
Where the money actually goes
- Electrical is the silent budget killer. A grooming van runs a dryer (1,800 to 4,000 watts), a water pump, lights, and AC. Doing that off-grid for a full day means a 280Ah to 600Ah lithium bank, a 3,000W inverter, and DC-DC charging. That single subsystem is often $6,000 to $12,000 installed.
- Hot water is non-negotiable. Dogs do not get clean in cold water, and clients notice. A propane on-demand heater or a 6-gallon electric tank with recovery is worth every dollar.
- Labor scales with plumbing and electrical complexity. A simple shelving upfit is 30 to 50 hours. A full grooming conversion is 120 to 220 shop hours, which is why labor dominates the table above.

What is the best layout for a grooming van?
The goal is a clean workflow loop: dog enters, gets bathed, moves to the table for drying and styling, then exits. Cross-traffic and backtracking waste time and stress the animal. Most efficient grooming vans use one of two layouts.
Galley layout (most common)
The tub sits at the rear over the back axle (lowest floor height, easiest dog entry), with the grooming table running along one side wall and cabinetry along the other. Water tanks live under the tub or under the table. This works in 148 to 159 inch wheelbase vans and is the layout we recommend for most single-groomer operations.
Side-entry layout
The tub mounts behind the side sliding door so dogs step in from the curb rather than the rear. This is friendlier for large or anxious dogs and for parking on narrow Los Angeles streets, but it eats into usable wall space and usually needs a longer van.
Key layout rules that hold across both:
- Keep the tub low and near an axle to minimize step-up height and keep weight centered. Loaded water tanks are heavy (more on that below).
- Put the dryer and electrical panel away from water. Separate the wet zone from the power zone with a solid bulkhead or cabinet run.
- Plan for a 30 by 48 inch table footprint plus standing room. A groomer needs to move around the animal.
- Ventilate aggressively. Hair, dander, and humidity build fast. A roof fan plus a powered intake keeps the box breathable and protects your electronics.
If you are still deciding between a Transit, ProMaster, or Sprinter, our breakdown of van types and platforms compares floor height, payload, and interior width, all of which directly affect grooming layout.
How does the water system work in a grooming van?
This is where grooming vans differ most from a camper or work van. You need fresh water in, hot water on demand, and gray water captured for legal disposal. You cannot dump dog wash water onto the street in California.
Tank sizing
A full grooming day is typically 4 to 8 dogs. Plan on 8 to 15 gallons of fresh water per dog including the final rinse, so a single-groomer van wants:
- Fresh tank: 35 to 60 gallons
- Gray tank: equal or slightly larger than fresh (always size gray at least as big as fresh, since you capture everything you use plus shampoo)
Remember that water weighs about 8.3 pounds per gallon. A combined 100 gallons of fresh and gray is roughly 830 pounds, which is a serious chunk of your payload. This is why tank placement low and over the axle matters, and why platform payload (covered on our van types page) is a real constraint, not a footnote.
The plumbing chain
- Fresh tank feeds a 12V or AC water pump (3 to 5 gallons per minute for good rinse pressure).
- Pump feeds the water heater, which feeds a single mixing faucet at the tub.
- The tub drains through a hair trap into the gray tank.
- Gray empties at an approved dump station or shop utility sink.
Heating the water
| Heater type | Up-front cost | Pros | Watch-outs |
|---|---|---|---|
| Propane on-demand | $700 to $1,400 | Endless hot water, low electrical draw | Needs propane storage, ventilation, annual inspection |
| Electric tank (6 gal) | $400 to $900 | Simple, no gas, no combustion venting | Big battery draw, recovery time between dogs |
| Hybrid (electric + engine heat) | $1,500 to $2,800 | Efficient, fast recovery | More complex install |
For a busy van running 6-plus dogs a day, propane on-demand is the workhorse choice. For a lighter schedule or a no-gas preference, a 6-gallon electric tank paired with a strong lithium bank is fine.
A heads-up on lead times: in 2026, quality grooming tubs and on-demand heaters often carry 2 to 6 week lead times, and custom stainless tubs can run 8 weeks. Order long-lead items before your build slot opens so they do not stall the project.
How long does a grooming van conversion take?
From greenlight to keys, plan on 4 to 10 weeks of shop time for a professional build, plus parts lead time on the front end.
- Design and planning: 1 to 2 weeks (layout, electrical load calc, tank sizing)
- Rough-in (electrical, plumbing, insulation): 1 to 3 weeks
- Cabinetry, tub set, finish: 2 to 4 weeks
- Commissioning and leak testing: a few days
DIY builds realistically take 3 to 6 months of weekends, and the plumbing and electrical are the parts most owners underestimate. If you are running a business, shop time usually pays for itself in faster revenue and a rig that passes inspection the first time.
What about electrical and power for the dryer?
The dog dryer is the single largest load in the van. A high-velocity dryer pulls 1,800 to 4,000 watts. Running that plus a water pump, lights, and AC off-grid for a full day requires real capacity.
A typical mid-range power system we install for a grooming van:
- Battery: 300Ah to 400Ah lithium (LiFePO4)
- Inverter: 3,000W pure sine
- Charging: DC-DC charger from the alternator (40A to 60A) plus shore power inlet for overnight top-off
- Optional: 200W to 400W rooftop solar to extend runtime
Some high-volume operators skip the big battery and run a quiet inverter generator or a secondary underhood alternator instead. Both are valid; the right call depends on how many dryer-hours you run per day. We size the bank from your actual dog count and dryer wattage rather than guessing, the same approach we use on our commercial van upfits for fleets.
Frequently asked questions
Can I convert a used van, or do I need a new one?
A used van is the smart budget move, and most grooming vans start life as used cargo vans. Aim for a Transit, ProMaster, or Sprinter under 120,000 miles with documented service and no rust in the cargo floor (rust under future water tanks is a real problem). Have the drivetrain inspected before you commit, since the conversion will outlive several engines if the base is sound.
How much does just the water system cost to install?
Tanks, pump, plumbing, hair trap, and a water heater typically run $2,500 to $8,000 installed depending on tank size and whether you choose propane or electric heat. The tub itself is separate, usually $1,200 to $4,500. Bundling it into a full build is cheaper than adding it later.
Do I need permits or special plumbing for gray water?
Yes. California requires you to capture gray water and dispose of it at an approved location, and many cities require a business license and health or environmental sign-off for mobile pet services. We build the gray system to capture everything, but confirm local rules with your city before you operate. Our specialty services team can advise on compliant tank and disposal setups.
Will the floor handle the weight of full water tanks?
It will if the system is engineered for it. A combined 100 gallons of water is roughly 830 pounds, so tanks must sit low and over an axle, and the build has to stay inside the van's payload rating. This is exactly why platform choice matters and why we run a payload calculation before finalizing tank size.
Can I start with a partial build and add the tub later?
You can, but it usually costs more in the end. Plumbing and electrical run cleaner when designed together. If budget is tight, a better path is a complete but simpler system (smaller battery, electric heater) that you upgrade later. Our van kits and van build options include tiers built for exactly this kind of staged investment.
How do I keep the van cool while grooming in summer?
You need real AC, not just a roof fan, for Inland Empire and inland Orange County summers. Most grooming vans run a 12V or shore-powered air conditioner plus aggressive ventilation to manage heat from the dryer and the dogs. We size cooling alongside the electrical system so the AC and dryer do not fight over the same power.
