Turning a regular van into the dream van you have in mind is an exciting adventure. But what's your reason for joining over 3.1 million van lifers in the United States? Epic road trips, working from different locations, or are you tired of paying rent for a tiny apartment?
Whatever your reason is, building your dream van means you'll be making dozens of decisions that will affect your comfort, safety, and wallet. It starts from choosing the right van to picking materials to deciding who's doing the work.
All it takes is a clear plan.
So if you're serious about building your dream van, here's a step-by-step guide to help you make smart choices.
Start with the Right Van
The first and most important move in building your dream van is selecting the right camper van. So, ask yourself these questions. Are you traveling/living solo or with someone? Do you need to stand up inside? Will you be living full-time or just on weekends?
The answers will help you come up with what kind of camper van model you’ll need, a Mercedes van or another model, as well as the size.
You’ll also need to decide if you want a used van or a completely new camper van. Expect to pay up to $10,000 for a used van and $53,125 to $80,000 or more for a new van, depending on the model.
Plan Your Layout
Now that you know the kind of camper van you want, the next thing is deciding how to build your camper van layout that'll work for your life.
What do you need inside your camper van? Do you need a workspace for remote work? Will you shower inside? Will you be cooking elaborate meals or just heating up canned food?
List out your must-haves, for example, bed, storage, power, and water. Then add nice-to-haves: a shower, a toilet, a big fridge, and a workspace. Your van conversion process should focus on essentials before luxuries.
Use paper or free apps to sketch your camper van layout, thinking about where everything will go before you start building.
Here are things you need to consider when building your camper van layout.
Don’t Hit the Road Without These Camper Van Items
Water and Plumbing
You’ll need fresh water tanks to hold clean water for drinking, cooking, and washing. Then, a gray water tank to collect used water from sinks and showers.
Install a quality electric water heater for a reliable shower setup and consistent hot water in your taps.
Here's a breakdown of what your camper van plumbing water system may cost.
-
Freshwater tank (10-30 gallons): $50-$200
-
12V water pump: $50-$150
-
Gray water tank $50-$150
-
Drain valves & fittings (small scale): $20-$600
-
Electric water heater $250-$600
-
Professional installation & wiring: $300-$700
-
Shower pan/drain kit: $100-$250
-
Waterproof wall panels or shower curtain: $50-$150
Beds and Living Space
Your camper van bed can be a fixed or convertible one. Think about whether you want a couch during the day and a bed at night.
A basic DIY fixed bed costs about $300 to $600. For a custom professional install, you’ll pay between $1,000 and $2,000 or more depending on the company and location.
For a convertible, a DIY will cost you up to $600, while a professional install will cost you between $1,000 and $1,800 or more.
Add finishing touches like curtains, cushions, and lights to make your van feel at home.
Insulation
You'll want to stay warm in the cold and cool in the heat inside your camper van. You have options such as sheep's wool, foam boards, and spray foam. Don't forget vapor barriers.
Be sure to install a special vapor barrier between the insulation and interior walls to prevent trapped moisture, which can lead to mold and rust.
Expect to spend between $300 and $2,000+ for insulation. The price depends on your choice of materials, the size of your camper van, and whether you opt for a DIY or professional installation.
Walls and Floors
After insulation, add wood panels or other materials to the walls. You have options such as pine tongue and groove or plywood.
Install your flooring next. Choose from vinyl planks that handle water spills and look like real wood or laminate, which costs less, but water damage ruins it.
The cost for these two largely depends on your choice of materials, design choices, and whether you opt for DIY or professional installation. Expect to spend $300 to $5,000 for walls and $200 to $1,200 for floors.
Windows and Ventilation
We know it'll sound scary as a first-time camp van builder, but you'll need to cut holes for windows or roof vents to create airflow, or your van will feel stuffy fast.
Roof vents pull hot air out while windows let air in. This creates airflow that prevents condensation.
The prices for windows rely on type and quality. Expect to pay $400 to $1,800. For ventilation, you’ll pay $400 to $1,000.
Kitchen and Storage
Your campervan kitchen can be basic or fully loaded. It depends on your cooking habits and budget.
Kitchen options include:
-
Built-in stove with two or three burners. These cost about $78-$300
-
Mini-fridge or 12V compressor fridge. It may cost you about $179-$1,100
-
Sink with running water and proper drainage $50-$1,500
-
Counter space for food prep and storage. For this, the prices will vary depending on your type of wood and finish.
Here's where you also figure out your storage options.
Your storage can go under beds, in cabinets, in overhead compartments, or behind front seats. Use soft-close hinges and locks to keep things secure while driving.
Think about weight distribution. Heavy items like water and batteries can sit low and centered. Light items like clothes can go in overhead cabinets.
Electrical and Power Systems
Last but not least, what it really takes to build your dream van is powering your van. Get this wrong and you'll sit in the dark with dead batteries.
For reliable power in your camper van, your electrical system needs several parts working together.
-
Solar panels charge batteries during the day ($500)
-
Deep cycle batteries store power for nighttime use ($153)
-
Inverter changes 12V battery power to 120V household power ($250)
-
A charge controller prevents batteries from overcharging ($100 to $615)
-
Fuse box and wires distribute power safely ($150+)
Size your system based on actual power needs, not guesses.
