Round Alfa cistern by Spek, suitable for wall installation. It is supported on the wall and at a height of approximately 1.5 meters above the toilet bowl. It is usually found in old buildings where the corresponding pipes for connection exist. The water is emptied with a button located at the bottom.

It is high pressure, which means that the water falls forcefully into the toilet bowl and has high pressure. For this reason, it has a smaller water capacity compared to a low-pressure cistern, as the water requirement is not as high.

It is made of plastic, which is a much more economical solution compared to porcelain. It is highly resistant to moisture and also has great durability over time.
