I used to have long hair, lived together with long haired people and had to clean the shower way too often. I was always annoyed by the useless shower drains, that are always blocked with hair.  Those days I moved several times, and after the third apartment and the third type of drain, I found out that all shower drains have the same problem.

So, I sat down and solved the problem. The first patent was filed in 2010. After seven years of development and preparation, I founded the Freilauf company in summer 2016 and started to organize the production. Since  2019 the Freilauf shower drain is on the market.
