one does its due diligence. We urge you to look around the web and compare our systems with others. You will find that our Waterless No-Flush urinals are the least expensive. Urinals start at $248, EcoTrap inserts/cartridges at only $7.75. They are the least expensive to operate plus we offer the most models on the market. Materials are our traditional and best selling HPC (High Performance Composites) as well as standard ceramic. HPC models also can be made in any color (5 units minimum).
