A combinitase is a hybrid of a sink and a regular toilet. Water from the sink above the toilet enters the cistern. The pros are obvious:

  • Saving water. Up to 25%! You washed your face, but the water did not disappear, did not immediately go down the drain. After filtration, it entered the toilet bowl and was reused.
  • Saving space. Often there is simply nowhere to put a sink in a cramped bathroom. And you need to wash your hands after using the toilet, you remember it well from childhood. Kombounitaz solves this problem by combining two types of plumbing.

The design of the combinitases can be different. There are the most compact models in which the sink is located directly on the tank and becomes its lid.

All models of combinitases, regardless of design, have two necessary parts:

  • Filter. The water from the sink doesn’t just go straight into the toilet cistern, it is cleared of soap and dirt. So there will be no unpleasant smell, during the drain the water is already clear. It is clear that not drinking, but purified.
  • Automatic control system for water overflow. Control takes place through a filter. You can calmly wash your hands for a long time, shave, without fear of flooding the bathroom. When the tank is full, the system will automatically stop the water flow.

Important! There is always a system for the usual supply of water to the toilet. You may not have enough water from washing your hands from the sink to fill the tank. In this case, she will act in the traditional way..
