Upgrade your composting toilet system with the S1 Dry Flush Adapter Kit, designed to transform your Cuddy or Cuddy Lite into a fully sealed S1 Dry Flush toilet system. If you’ve been eyeing the S1 Sealing Toilet but already own a Cuddy, this adapter kit provides an innovative way to upgrade your existing setup.
The S1 Dry Flush system seals waste in individual liners after each use, helping reduce odors while providing a cleaner and more convenient toilet experience for overland travel, van life, RV use, and remote camping.
This kit includes the core components needed to convert your existing Cuddy unit to the S1 sealing system, including the sealing mechanism, solids bin, battery pack, and control panel assembly. Once installed, the system allows you to operate the sealing function with the integrated control panel for simple and hygienic operation.
The S1 Dry Flush Adapter Kit is currently available for preorder with an expected delivery date of February 2026.
If you already own a Cuddy or Cuddy Lite and want the convenience of a sealed waste system without replacing your entire toilet, this upgrade kit offers a powerful and flexible solution.
