The bathroom is one of the most important aspects of any residential or commercial building. Therefore, you should think of every feasible way to make it not only comfortable but also highly functional, elegant, and spacious. Investing in high-tech toilet fittings and flushing systems such as concealed cisterns and WC flush valves are a better decision in today’s world.

A concealed tank toilet creates a sense of spaciousness in the bathroom and makes it appear opulent. The toilet flush or actuator, as well as the WC, are the only visible pieces of a concealed cistern, with the rest concealed behind walls or in a cabinet. Only the flush buttons are visible because the toilet bowl appears to be linked to the wall. The exposed cistern, on the other hand, has the top tank visible from the outside and is positioned at the back of the toilet bowl.

Due to its affordability, an exposed cistern is the most prevalent form of toilet found in households and offices. A concealed toilet, on the other hand, is one of the modern bathroom concepts that is gaining traction among bathroom enthusiasts.

Depending upon your requirements, this article will give you the best alternatives in the market with German technology and also highlight their advantages & tech specs.
