How Long Does a Van Conversion Take?

The Honest Answer

A professional van conversion takes 6 to 16+ weeks depending on the scope. That surprises some people — they see YouTube videos of weekend builds and think a full conversion should take a month. But building a van that's safe, reliable, and finished to a standard you'll be happy with for years takes real time. Cutting corners on timeline means cutting corners on quality, and we don't do that.

Here's how timelines break down by build tier, what happens during each phase, and what factors actually push timelines longer.

Timelines by Build Tier

Basic Builds: 6-8 Weeks

A basic build ($30K-$50K) includes insulation, flooring, a bed platform, a kitchen with a cooktop and sink, a 12V electrical system with solar, basic plumbing, and a vent fan. The layout is functional and straightforward — fewer custom elements, standard material choices, and a simpler electrical system.

Six to eight weeks covers demolition and prep, insulation, framing, electrical rough-in, plumbing rough-in, interior buildout, systems installation, testing, and cleanup. Some basic builds finish closer to 6 weeks; others push toward 8 depending on van condition and specific design choices.

Standard Builds: 8-12 Weeks

A standard build ($55K-$75K) adds complexity: a larger electrical system with more solar and battery capacity, a diesel heater, hot water, upgraded cabinetry with soft-close hardware, better finishes, and more custom design work. The kitchen is more functional, the lighting is more thoughtful, and the overall fit and finish is a step up.

The extra time comes from more systems to install and integrate, more custom woodwork, and more time testing everything. A diesel heater installation alone adds a day or two between mounting, fuel line routing, ducting, and testing. Hot water plumbing adds another day. These things compound.

Premium Builds: 12-16+ Weeks

A premium build ($80K-$120K+) is where the craftsmanship really shows. Custom cabinetry with fine joinery, high-end finishes, larger electrical systems with advanced monitoring, multi-zone heating, a full bathroom, and design details that take time to execute well. The systems are the same as standard in most cases — the difference is how everything is built and finished.

Premium timelines are longer because precision takes time. Fitting a custom cabinet with perfect reveals and alignment takes longer than building a functional box. Routing wiring so it's invisible takes longer than running it along the wall. Sanding and finishing to furniture quality takes longer than a basic clear coat. There's no shortcut for this kind of work.

What Happens During Each Phase

Every build at our San Diego shop follows the same general sequence. Here's where the time goes:

Week 1-2: Demolition, Prep, and Insulation

We strip out the factory interior (carpet, plastic panels, headliner), clean and treat the metal, address any rust, and insulate the entire shell with Thinsulate (walls and ceiling) and XPS foam (floor). This is the foundation of the build — rushing insulation leads to condensation problems, poor thermal performance, and issues down the road.

Week 2-4: Framing, Electrical, and Plumbing Rough-In

We build the interior framing (wall furring strips, ceiling structure, floor subfloor), then run all electrical wiring and plumbing lines before the walls go up. This is like the framing and rough-in phase of building a house — everything behind the walls gets done now because once the walls are paneled, you don't want to tear them open again.

Electrical rough-in includes running wire for every light, switch, outlet, fan, fridge, heater, and solar connection. Plumbing rough-in includes fresh water lines, grey water drain lines, and hot water routing if applicable. All of this is planned before a single wire gets pulled.

Week 3-6: Interior Buildout

This is where the van starts looking like a van. Wall paneling goes up, flooring goes down, the bed platform gets built, the kitchen cabinetry is fabricated and installed, the bathroom (if applicable) gets framed and finished, and all the visible woodwork takes shape. This phase overlaps with electrical and plumbing work — we install outlets, switches, and fixtures as the walls and cabinets go in.

Cabinetry is the most time-intensive part of the interior. Every cabinet is custom-built to fit the van's specific dimensions. Nothing is off-the-shelf. In premium builds, this phase alone can take 3-4 weeks because of the precision involved.

Week 5-8: Systems Installation and Integration

Now the major systems get installed and connected. The electrical panel goes in, solar panels mount to the roof, the battery bank gets wired, the inverter and charge controllers are installed, the diesel heater gets mounted and ducted, the water pump and tank get plumbed, and the fridge, stove, and sink get their final connections.

Integration is key here. Everything has to work together — the solar charges the battery, the battery powers the inverter, the inverter runs the outlets, the outlets power your devices. If one connection is wrong, the whole chain breaks. We take time to route wiring cleanly, label every circuit, and document the system for your reference.

Final 1-2 Weeks: Testing, Finishing, and QC

Before handoff, we test every system. Electrical circuits get load-tested. Plumbing gets run and checked for leaks. Propane connections are pressure-tested. The diesel heater runs through a full heat cycle. Solar charging is verified. Every light, switch, outlet, fan, and pump is confirmed working. We check fit and finish on all cabinetry, trim, and visible surfaces.

This phase catches issues before you do. It's easier to fix a loose connection in the shop than on the side of a highway in Utah. We don't skip or rush this phase, and it's one of the reasons our build process includes a dedicated testing step.

What Actually Causes Delays

Timelines shift. Here's what pushes them:

Materials and Parts Lead Times

Some components have lead times. Specialty appliances, specific fridge models, custom windows, or particular electrical components sometimes take 2-4 weeks to arrive. We order materials as early as possible — usually before the van arrives at the shop — to minimize this. But supply chain delays happen, and when a critical part is backordered, it can push the timeline.

This is one reason we collect the 50% commencement payment 30 days before the van arrives. It gives us time to order everything and have it in hand when the build starts.

Design Changes Mid-Build

Changing your mind during the build costs time. Moving the fridge to the other side of the kitchen after the plumbing is roughed in means redoing plumbing. Adding a window after the walls are paneled means cutting, framing, and finishing. We encourage finalizing your design during the planning phase so the build itself stays on track.

Small changes (different cabinet hardware, a different paint color) are easy. Structural changes (different layout, added bathroom, different bed configuration) can add days or weeks.

Van Condition

A new cargo van with no issues is straightforward. A used van with rust, previous damage, or aftermarket modifications that need to be removed or corrected takes more time upfront. We inspect every van before the build starts and flag anything that needs attention. Rust repair, in particular, can add a week if it's extensive.

Shop Capacity

Like any build shop, we schedule projects sequentially. If a previous build runs long, it can push your start date. We communicate proactively about scheduling — if there's a delay, you'll know about it before it impacts your timeline. This is also why booking your build slot with a deposit early gives you priority on the calendar.

Custom Features Take Custom Time

Anything one-of-a-kind takes longer than something we've built before. A custom sliding table, a murphy bed mechanism, a unique storage solution, or an unconventional layout all require design time, prototyping, and iteration. These features are part of what makes your build yours, but they add to the timeline. We'll always tell you upfront when a custom feature will impact scheduling.

Why You Can't Rush a Good Build

Speed and quality are at odds in van conversion. Building faster means less time for precise cuts, careful wiring, thorough testing, and quality finishing. Rushed builds have more callbacks, more problems on the road, and more things that need to be redone later.

We've seen vans from other shops where the builder clearly rushed. Wiring that's not secured properly. Cabinets with visible gaps. Plumbing that leaks within weeks. Solar connections that corrode because they weren't sealed. These problems stem from insufficient time, not lack of skill.

Our approach is straightforward: we tell you how long the build will take based on the scope, and then we take that time. No shortcuts, no promises we can't keep.

How We Keep Projects Moving

Staying on timeline requires planning, not hope. Here's what we do:

• Pre-order materials. We order long-lead items weeks before the van arrives so they're on hand when we need them.
• Finalize design before building. Every detail is approved during the planning phase. No guessing during construction.
• Progress updates. We send you photos and updates throughout the build so you see what's happening and can flag concerns early.
• Sequential workflow. Each phase feeds the next. Insulation before framing, framing before wiring, wiring before walls. No skipping ahead and backtracking.
• Buffer for unknowns. Our timeline estimates include padding for the unexpected. We'd rather finish a day early than a week late.

Planning Around Your Timeline

If you have a target date — a trip, a lease ending, a life change — tell us during the consultation. We'll be honest about whether your timeline is achievable for your build scope. If it's tight, we can discuss simplifying certain elements to hit the date, or we can adjust the start date to give the build the time it needs.

The best approach: reach out to us 2-4 months before you want the build to start. This gives us time for consultation, design, scheduling, and materials ordering before the van ever arrives at the shop. For a look at what the overall build investment looks like, see our van conversion cost page.
