Our most complete, highest-capacity campervan water system - built for full-featured, off-grid van conversions.
 
The Premium Van Plumbing Kit is engineered for serious DIY builders and professional converters who require maximum flexibility, extended pipe runs, and advanced system zoning.
 
Designed to support complex layouts - including indoor and outdoor showers, dual sinks, hot water heaters, and higher daily water usage - this kit provides expanded pipe lengths and additional isolation valves for larger vans and demanding builds.
 
If you’re building a fully off-grid campervan with high water demand and multiple fixtures, this is the ultimate all-in-one plumbing solution.
 
🔧 Why We Use This Premium Kit
This configuration represents the highest-spec freshwater system layout we implement in premium van conversions.
 
It’s built for:
• Multi-outlet campervan water systems
• Indoor and outdoor shower setups
• Integrated gas or electric water heaters

This is not just a plumbing kit.
It’s a structured, expandable, professional-grade water system.

This kit is designed for premium van conversions where plumbing flexibility, service access, and long-term reliability are non-negotiable.
