The owner of a vacation home or apartment knows the scenario. He opens up for a weekend and everything is clean. He returns two to four weeks later to a stench in the basement, bathroom, and garage. The traps dry out while the place is empty. Green Drain™ is a solution you install once and forget for five years.
A holiday house on the coast, a let apartment in the city, a basement flat, a garage with a floor drain — everyone knows the smell that greets them on the way back in.
According to DZS data, in 2024, Croatia has 1.2 million permanent beds in commercial accommodation and 448,000 rooms and camping sites. A large portion of this consists of private renters — owners of apartments, houses, and vacation homes who face the same seasonal problem.
