The walls and ceiling define the character of your van's interior. From warm cedar planks to clean white panels, your choice here sets the tone for the entire space. Here's what works best and what to avoid.
Before you pick materials, think about what's going behind your wall and ceiling panels. Once they're installed, getting back to wiring, insulation, or plumbing is a pain. So plan these things out first:
Also think about how your walls interact with your furniture. If a cabinet runs floor-to-ceiling against a wall, you might not need a beautiful finish behind it - plywood or even bare insulation might be fine behind furniture that covers the wall permanently.
The Instagram-famous van build look. Cedar is most popular because it smells great, resists moisture naturally, and has a beautiful grain. Pine is cheaper but should be sealed with polyurethane to protect against moisture.

The downsides:
Thin plywood (1/8" or 1/4") cut to fit your wall sections. One of the most practical choices - lightweight, affordable, and it bends to follow the curves of your van. Can be painted, stained, or whitewashed for different looks.

The downsides:
Plastic wall panels designed for wet environments. Available in white, wood-look, and other finishes. Completely waterproof, easy to clean, and lightweight.

The downsides:
Rigid foam or plywood covered with upholstery fabric or marine vinyl. Common in professional builds and high-end DIY builds. Creates a soft, finished look that hides imperfections.

The downsides:
Ceilings are trickier than walls because of curves and because weight matters more (everything is fighting gravity). You also want a light-colored ceiling to make the space feel larger and brighter.
Color matters more than material: A white or light ceiling makes a van feel significantly more spacious. Even if you use wood walls, consider a white ceiling. The contrast between warm wood walls and a bright white ceiling looks great and opens up the visual space.
Use a quality latex paint or a stain + polyurethane combo. Primer is important on raw plywood - it prevents the wood grain from showing through paint and reduces the number of coats needed. Two coats of paint over primer gives a clean, durable finish.
Cedar can be left natural (it still benefits from a clear coat for moisture protection). Pine should be stained and sealed. Many builders use a whitewash technique on pine for a bright, beachy look that's less expensive than cedar but more interesting than painted plywood.
Use satin or semi-gloss finishes rather than flat/matte. They're easier to clean and more moisture-resistant. Light colors make the space feel larger. Do your painting before installation when possible - it's much easier to paint panels on sawhorses than overhead in a van.
Areas around your sink, near door openings, and anywhere water might splash need extra attention:
Budget build: 1/4" luan plywood everywhere, painted white. Lightweight, cheap, and surprisingly good-looking. Total cost for walls and ceiling: $50-100 in materials plus paint. This is what I'd recommend for most first-time builders.
Mid-range build: Tongue and groove cedar or pine on the walls, painted white plywood ceiling. This gives you the warm wood look on the walls where you see and touch them most, while keeping the ceiling light and bright. Total cost: $200-500.
Premium build: Cedar T&G everywhere, fabric-wrapped panels for accent areas, PVC in wet zones. Total cost: $500-1,200.
Whatever you choose: light-colored ceiling, waterproof materials in wet areas, and don't forget to plan your electrical before closing up walls.
