Modulo Clean is the world’s flattest shower drain (making it perfect for renovation projects) and it requires almost no cleaning! Thanks to its improved siphon with our Dryphon® technology, it is now more powerful and convenient. The Dryphon® has a high-tech silicone valve that blocks any odour from the waste piping, without the use of water. This provides higher drainage capacity and requires less maintenance. In addition to our Dryphon® technology siphon, Compact Clean includes a conventional water seal. Choose your ideal option .
