Meet our taps
A water cooler or Syrup Bar in your hotel brings with it a sustainable and high-quality service. Read more about the benefits.

Your guests can tap their own unlimited filtered, cold and sparkling water. You don't have to put single-use plastic bottles in the hotel room. This saves on procurement costs and contributes to a unique guest experience. You also have fewer logistical operations, such as storage and packaging. This saves a lot of lugging crates around and you no longer have to charge a deposit.

Of course, the most important thing is to make your hotel more sustainable. With our water dispensers, you drastically reduce your footprint and ensure a cleaner planet.

Say goodbye to unnecessary packaged water. Personalized water carafes allow your guests to use the various water taps at any time of the day.

In addition to offering water to your guests, it is also important that your employees drink enough water. A cold water device such as a water tap in the workplace encourages them to drink enough. This will increase the ability to concentrate and you have less chance of staff absenteeism.

With a lemonade tap also called the Syrup Bar, you have the alternative to traditional soft drinks and juices. With refreshing lemonade syrup, you can provide your hotel guests with healthier and natural soft drinks. Without unnecessary packaging and transportation. So you save time, money and reduce C02 emissions.

The taps use a water filter to provide you with clean water. In addition, the taste will be purer and extend the life of the water cooler. This is because of the limescale regulating function.
The bamboo we use for our Zereau Drinks water taps offers sustainable advantages over other materials. This is because bamboo grows at a tremendous rate and requires very little water. Furthermore, our supplier of bamboo conducted an LCA and C02 footprint study together with Delft University of Technology and INBAR. The report showed that all solid bamboo products are C02 neutral over the entire life cycle. Perfect material for a sustainable water tap.
