After years of installing every shower stall on the market — and warrantying too many cracks, leaks, and rust spots — we started spec'ing our own. The Vankea 28" is the size most 144" Sprinter builds and tight ProMaster layouts end up choosing. Roomy enough to stand and turn in, narrow enough to leave wall space for the kitchen, closet, and bench you actually need.
Why we put this in our own builds
Most van showers fail in the same places. Fiberglass cracks from road vibration. Plastic stalls warp. Sealant lines split after a season of travel. We got tired of warrantying other people's products, so we built one we trust.
Aluminum panels, not fiberglass. Won't crack from vibration. Won't rust.
Powder-coated finish. Easy to wipe clean. Doesn't grow mold the way porous surfaces do.
Telescoping height. Adjusts to fit standard and high-roof builds — 73" at minimum, taller when extended.
Rear plumbing cavity. Water lines hide inside the wall, so the finished bathroom looks clean — not like a DIY project.
Flat-packs for shipping, bolts together with the included hardware. No custom fabrication.
Light. 53 lbs vs. 150+ lbs for comparable fiberglass units. Your van's payload thanks you.

Maintenance & care
Wipe down after each use to keep the powder coating fresh.
Use: Mild soap, dish soap, or Simple Green
Avoid: Bleach, abrasive scrubbers, citrus-based cleaners — these will dull the finish over time
Regular wipe-down prevents soap scum and extends the life of the finish
