Most people have little thought about choosing a cistern for their toilet. Perhaps they can simply have the toilet installed by an installer or quickly buy the products that are currently in stock at the hardware store. But if you value the ecological use of water in your toilet or have to take special spatial conditions into account, you will quickly face difficult decisions:

– Where can you mount a sink in a narrow toilet?
– How can you use a toilet with gray water (process water)?
– Do I need an installer for the assembly?

You know this problem: you would like to have a sink in your toilet, but simply can't find a place for it. Because even the sinks with the smallest depth usually protrude more than 20 cm into the room - and are then also expensive.

With the combination cistern from GRANDESYS you no longer have to search for small sinks and complicated mounting options in your toilet. Because it is integrated in the cistern, the washbasin does not take up any space. And thanks to the compact dimensions of 38 cm in width and 17.5 cm in depth, the combination cistern fits in every toilet.

Could your guest toilet need a washbasin? Then try that GRANDESYS Combination cistern and convince yourself of our unique solution.

In Central Europe, this topic is not given a lot of thought, as there is no water shortage in most places. In other countries, however, water is precious and the use of gray or industrial water is necessary.

But what is gray water anyway? As the name suggests, gray water is no longer entirely clear. It is always produced when drinking water is used for washing, for example when showering, washing clothes or washing hands in the sink. Simply throwing it away would be a shame, because this water is ideally suited for use in the cistern. But anyone who has ever tried to catch it in a tub and fill it up later knows how difficult it can be to behave ecologically correct.

This is exactly where the concept of GRANDESYS Combination cistern. The combination of wash basin and cistern means that the water is always used twice: first for washing hands, then for rinsing. A person in Central Europe uses around 2-3 liters of water a day to wash their hands. The potential of saving water in a 2-person household with the GRANDESYS The combination cistern therefore holds up to 2,000 liters of drinking water per year.

In order to be able to offer our cistern as cheaply as possible, we rely on international standard dimensions: 1/2 inch for the water inlet and 50 mm diameter for the downpipe. Any adapters for these connections can be bought in any hardware store. A suspension for the cistern and suitable screws and dowels are included in the product scope. The installation of the cistern is quick and easy - and the right wash basin is included.
