CompoCloset™ | S1 Dry Flush Sealing Toilet

The CompoCloset™ S1 Dry Flush Sealing Toilet is a compact, self-contained toilet designed for boats, RVs, campervans—and even as a tidy bedside commode at home. It delivers a clean, waterless, chemical-free experience with push-button sealing that keeps everything hygienic, fresh, and out of sight. The built-in urine diverter means fewer “flushes,” less plastic, and no need to bag liquids, making day-to-day use simple and cost-effective.

✅ Green Sticker Compliant (Plumbers, Gasfitters, and Drainlayers (Self-Contained Vehicles) Regulations 2023)

Unique in the category: the S1 is the world’s first urine-diverting dry-flush (sealing) toilet—separating liquids from solids before heat-sealing the solids. Choose liners made from either compostable film or recycled plastic to suit your disposal preferences.

S1 Design Features:

• Push-button, battery-powered heat-seal mechanism; simple to use, no chemicals required
• Urine diversion reduces bag use (no more “paying to pee”) and keeps things drier and fresher
• Discreet containment and simple management: solids are sealed in small liners for easy, hygienic emptying
• LED urine-level indicator for timely, mess-free emptying
• 6.5L Liquids Chamber
• 15L Solids Chamber
• Power & runtime: internal rechargeable 12 V battery for sealing (50+ seals per charge) and a 9 V battery for the LED indicator
• Portable, low-profile design with side handles
• Low-cost, eco-friendly liner options: your choice of compostable liners or recycled-plastic liners

The S1 dry-flush toilet offers a hygienic, odour-free, low-maintenance solution for travel, tiny spaces, and bedside commode convenience. Its sealed-liner system keeps contents discreetly out of view—ideal where privacy and ease of care matter—while urine diversion cuts plastic use and extends time between empties.
