What order should I convert my van in?
Start with insulation and flooring, then electrical rough-in, plumbing rough-in, wall paneling, cabinetry and furniture, and finally finish work like countertops and trim. Solar and roof vents should go in early since they require roof cuts before interior panels are up.

A professional van conversion typically takes 6-16 weeks depending on scope. Basic builds run 6-8 weeks, standard builds 8-12 weeks, and premium builds 12-16+ weeks. DIY conversions often take 3-12 months depending on experience and available time.
How much does it cost to convert a van?
Professional van conversion costs range from $30,000 to $120,000+ for labor and materials (not including the vehicle). Basic builds with functional electrical, plumbing, and livability run $30K-$50K.
