One of the most common questions we get at Beachside Custom Vans is “How long will my van conversion take?” It’s a fair question – you’re making a significant investment and need to plan your timeline. After completing over 200+ van builds in Jacksonville, Florida, I can give you some real-world insights into van conversion timelines.
The short answer? It depends. But let me break down the realistic timelines based on what we see in our 5,000 sq ft shop every day.
Quick Timeline Overview
DIY Builds: 6-18 months (working weekends)
Professional Full Build: 8-16 weeks
Spec Model Build: 6-10 weeks
Small Jobs & Upgrades: 1-7 days
Now let’s dive into the details.
Professional Van Conversion Timelines
Full Custom Builds: 12-16 Weeks
When someone comes to us for a completely custom van conversion, we’re typically looking at 12-16 weeks from start to finish. This timeline includes:
- Week 1-2: Design phase and ordering materials
- Week 3-4: Insulation, electrical rough-in, and plumbing
- Week 5-8: Wall panels, ceiling, and cabinetry construction
- Week 9-12: Installation, electrical finish work, and plumbing connections
- Week 13-16: Final details, testing, and quality control
Why does it take this long? A custom van conversion involves hundreds of individual components that need to be precisely measured, cut, and installed. Our team of five specialists (Jonathan, Brad, Terry, Darren, and Andrew) each handle different aspects of the build, but certain tasks can’t be rushed.
For example, our woodworker Darren spends 2-3 weeks just on cabinetry for a full build. Edge banding, assembly, and finishing work all take time when you’re creating custom pieces that fit perfectly in a curved van interior.
Spec Model Builds: 6-10 Weeks
In 2025, we pivoted to offering spec models – standardized layouts that we’ve perfected over multiple builds. These take significantly less time because:
- All panels are pre-designed in Fusion 360 and cut on our CNC router
- We know exactly what materials to order
- The workflow is streamlined since our team has built the same layout multiple times
- No design revisions or custom modifications
We’re currently running two spec van builds alongside our custom projects as test runs, and the efficiency gains are dramatic.
Small Jobs: 1-7 Days
Not every project is a full conversion. We also handle:
- Window installations: 1-2 days
- Roof vent and fan installs: Half day to 1 day
- Electrical system upgrades: 2-3 days
- Exterior accessories: 1-3 days
- Air conditioning installs: 2-4 days
Jonathan handles most of these smaller projects and will be taking them over completely after he graduates from UNF in May 2025.
DIY Van Conversion Timelines
If you’re tackling a DIY conversion, expect a much longer timeline – but that’s not necessarily a bad thing. Most DIY builders work evenings and weekends, which naturally extends the process.
Realistic DIY Timeline: 6-18 Months
Weekend Warriors (8-12 hours per week): 12-18 months
Dedicated DIYers (20+ hours per week): 6-12 months
Full-time DIY (rare): 3-6 months
The wide range comes down to experience level, tool availability, and how much help you have. First-time builders always take longer than expected.
Common DIY Timeline Killers
- Analysis paralysis: Spending months planning instead of building
- Tool acquisition: Realizing you need tools you don’t have
- Skill learning curve: YouTube University takes time
- Rework: Fixing mistakes adds weeks to the timeline
- Weather delays: Working in driveways or garages limits progress
Factors That Affect Van Conversion Timeline
1. Van Platform Choice
Mercedes Sprinter: These typically take longer due to more complex electrical systems and tighter tolerances. Quality is worth it, but expect an extra 1-2 weeks.
Ford Transit: Our most efficient platform. Great proportions and easier electrical work.
RAM ProMaster: Budget-friendly but requires more creative solutions for certain installations.
2. Complexity Level
Basic Weekend Setup: Bed platform, 12V fridge, simple electrical (2-4 weeks professional, 2-4 months DIY)
Mid-Level Build: Full kitchen, bathroom, proper insulation, solar (8-12 weeks professional, 6-12 months DIY)
High-End Luxury: Custom everything, lithium systems, composting toilet, water heater, etc. (12-16 weeks professional, 12-18 months DIY)
3. Seasonality and Scheduling
In Florida, we’re lucky to work year-round, but we still see seasonal patterns:
- Winter months: Our busiest time (December-March)
- Summer: Slightly slower, better for DIY outdoor work
- Hurricane season: Potential delays if we get hit
Currently, we’re booked about 3 months out, which is much better than our historical 6-12 month backlog.
4. Material Availability
2024 taught us a lot about supply chain challenges. We now keep more inventory on hand, but certain specialty items can still cause delays:
- Custom-sized lithium batteries: 2-4 week lead time
- Specialty van windows: 3-6 week lead time
- High-end appliances: 1-3 week lead time
How We Keep Projects On Schedule
Pre-Construction Planning
Before we touch a van, we spend serious time planning:
- Complete material list and ordering (Terry handles this)
- Detailed cut sheets for our CNC router
- Electrical diagrams and component layout
- Clear milestone schedule
Workflow Optimization
Our team works in parallel when possible:
- While Brad handles exterior modifications, Terry can rough in electrical
- Darren builds cabinetry while Andrew preps wall panels
- Final assembly brings everything together
Quality Control Checkpoints
We’ve learned that catching issues early saves time later:
- Electrical testing before wall installation
- Plumbing pressure tests before finishing
- Final systems check before delivery
Setting Realistic Expectations
Here’s the truth: every van conversion has surprises. Even with our experience, we budget extra time for:
- Hidden rust or damage: Adds 2-5 days
- Custom modifications: Mid-build changes can add weeks
- Component failures: Sometimes parts arrive damaged
- Weather delays: For exterior work
Tips for Managing Your Timeline
If You’re Going Professional
- Book early: Good shops are booked months ahead
- Be decisive: Design changes mid-build add time and cost
- Plan for delays: Don’t book your cross-country trip the day after pickup
- Stay involved: Regular check-ins help catch issues early
If You’re Going DIY
- Start with a solid plan: Measure twice, cut once
- Buy tools first: Don’t halfway through realize you need a jigsaw
- Practice techniques: Test your skills on scrap material
- Accept imperfection: Done is better than perfect
- Get help: Some jobs really need two people

- Trying to save money on professional help for complex systems
- Not having proper tools for DIY builds
Time Savers
- Clear vision from the start
- Quality components that work the first time
- Proper planning and material ordering
- Working with experienced professionals
- Standardized layouts (spec models)
The Future of Van Conversion Timelines
Looking ahead to 2026 and beyond, I see timelines getting more predictable:
Technology Improvements
- Better design software reduces errors
- CNC automation speeds manufacturing
- Improved component quality reduces failures
Industry Maturation
- More standardized layouts and components
- Better supplier relationships and inventory
- Experienced workforce
Our 2026 Goals
We’re aiming to:
- Reduce spec model builds to 6 weeks consistently
- Build and sell 100 vans (mix of spec and custom)
- Focus more on systems and less on custom everything
The Bottom Line
A professional van conversion typically takes 8-16 weeks, while DIY builds range from 6-18 months. The key is setting realistic expectations and planning accordingly.
At Beachside Custom Vans, we’ve learned that rushing leads to mistakes, and mistakes cost more time than patience. We’d rather deliver a van that’s done right than one that’s done fast.
