How long does a van conversion take?

What really sets the clock on a van conversion

As a rule of thumb, most builds land between six and twenty four weeks, but that range widens or shrinks based on scope, parts availability, and shop workflow. Asking how long does a van conversion take is like asking how long it takes to renovate a home; complexity and coordination decide everything. A thoughtful plan, quick decisions, and a realistic parts plan are the backbone of an on time handoff.

The platform matters. Mercedes Sprinter, Ford Transit, and Ram ProMaster each bring unique packaging, wiring, and mounting realities that influence design and install speed. A build that uses pre engineered components and proven layouts tends to move faster than one that requires one off fabrication and custom cabinetry.

Parts lead times shape the middle of the schedule. Electrical gear, lithium batteries, inverters, heaters, windows, roof fans, and specialty hardware may have multi week backorders during peak season. Smart builders sequence work so that interior framing, insulation, and wiring progress while waiting on long lead items.

Typical timelines by build type and scope

Time estimates below assume the base vehicle is in hand and ready for work. Add any additional time for vehicle procurement and transport.

• Starter interior refresh, no major power: four to eight weeks
• Partial upfit with cabinet kit, roof fan, basic power: six to ten weeks
• Adventure build with hot water, solar, heat, and a full galley: ten to sixteen weeks
• Full custom with shower, high output electrical, and custom metal work: twelve to twenty four weeks

Key project stages and common durations:

• Discovery and design: two to four weeks for measurements, layout, and selections
• Engineering and documentation: one to three weeks for wiring diagrams, weight planning, and ventilation paths
• Ordering and kitting: two to six weeks depending on supplier queues
• Fabrication and carpentry: four to ten weeks based on complexity and finish level
• Electrical and plumbing integration: two to five weeks, including testing
• Finish and detail: one to three weeks for trim, soft goods, and coatings
• Shakedown and quality checks: one to two weeks of functional testing and road validation

Platform and layout choices

Choosing a layout that aligns with the van’s wheelbase and roof height reduces surprises. High roof vans speed interior work by improving access and fitment for cabinets and showers. Short wheelbase platforms build faster but carry tighter packaging and tank size tradeoffs.

Electrical and climate systems

High capacity lithium banks, secondary alternators, air conditioning, diesel heaters, and induction cooking extend timelines due to wiring complexity, airflow routing, and calibration. The time is well spent when it prevents voltage drop, nuisance trips, and noise issues later on.

Fabrication and finish level

True custom metal work and hand built cabinetry add weeks but deliver a tailored fit and quieter cabin. Prefinished laminates install faster than hardwoods. Sprayed coatings and cure times must be scheduled to avoid bottlenecks.

How to keep a van build on schedule

You can influence time more than you think by tightening the front end of the process and staying decisive during production.

• Lock the scope early: Approved drawings and a frozen features list keep change orders from resetting the schedule
• Preselect materials: Confirm appliances, finishes, fabrics, and fixtures before parts are ordered
• Be flexible on brands and colors: Accepting equivalent components can bypass backorders
• Choose proven layouts: Known patterns enable faster install and fewer revision cycles
• Approve fast: Quick feedback on design checkpoints prevents idle time in the shop
• Avoid peak season starts: Spring and early summer see strained supplier capacity
• Plan time for testing: A thorough shakedown avoids follow up visits and protects trip dates

How long does a van conversion take if you already own parts

Bringing your own components does not always shorten timelines. Shops still need to validate compatibility, warranty implications, and safety standards. When parts arrive incomplete or mismatched, the schedule can elongate. A consolidated parts kit with clear specifications improves predictability.

What can extend the schedule

• Late stage design changes that affect wiring or plumbing paths
• Additional rust remediation or body work discovered during tear down
• Rework when items are temporarily installed without final hardware
• Delivery delays for custom glass, roof racks, or specialty fasteners

What you should expect at handoff

A real handoff includes a walkthrough, labeled panels, documentation, and a test drive. Quality shops provide system schematics, maintenance intervals, and safety checklists. Plan time to camp locally for a night and report any small adjustments after first use.

Planning your timeline around real life dates

Back into your target adventure date with buffers. If you need a completed rig by early June, aim for April for substantial completion and allow a few weeks for shakedown, registration updates, and insurance notes. Airline and lodging plans are easier to book once the van clears the testing stage.

If you are financing the platform, work with lenders early so the vehicle is titled and ready to enter production. If you are chasing a specific model or trim, begin sourcing months in advance to avoid starting your build late.

Where OZK Customs fits into the timeline conversation

While the guidance above stands on its own, an experienced builder brings structure to each step. Our team sequences design, procurement, fabrication, and validation so the schedule remains visible and accountable. We prioritize reliable power, safe plumbing, clean wiring, and durable finishes, then verify them under real road conditions around Northwest Arkansas before handoff.

If you are exploring layouts and finish levels, see our recreational vans for examples of scope and features that pair well with different timeframes:

• Explore our recreational vans at recreational vans
• For a ground up approach, review a custom van build
• If you prefer finance friendly options, browse Mainstream vans

When you are ready to move from research to dates on a calendar, we will define scope, confirm parts, and assign a slot that fits your season. That is how you answer the question how long does a van conversion take with confidence rather than guesswork.

Tell us when you want to hit the road and what you must have on day one. We will map your build to a clear schedule, line up parts, and deliver a rig that is tested, documented, and ready for your first night out. Fill out the form to reserve your place in our production queue.
