It's incomprehensible why Geberit doesn't offer a larger tank as an accessory. That would be a piece of cake - and Geberit could even earn money with it! The appliance would just be a few centimetres higher, which would bother very few people.

Hello,
Bought this product perfect except for water tank.. Now Fixed issue with 12 liter tank.,
You need the following,
Electrical Horizontal water float, when tank is full the float is up and breaks the electrical circuit.
5v DC water pump,
Water tank, as large as you like.
USB Power bank.
2 Jobs need to be done on original tank, Drill hole near top for water float to go in Horizontal leave room so the float does not touch the lid, and another small hole for the water pipe.
Now my tank fills automatically every time the float drops down, the circuit is closed and it starts the water pump.
You can buy the float by Digitec and the other stuff any where else.
Now only fill my tank every few days...
Other wise perfect product,, I would recommend, plus I did contact manufacture but they informed me there is no option to expand tank at all....
