We are about to start construction. In the basement, there will be a washing machine and a condenser dryer, as well as a small handwashing basin, which will probably be used only very rarely. The architect is now asking whether we want to install a sump pit with a pump or a prefabricated plastic unit called a "Jung Baufix," with the trend leaning toward the Baufix. The floor drain is already integrated into the lid of the Baufix.
Does anyone know this system? I can get the parts for the sump pit cheaper through a company, but it has higher installation costs than the Baufix. The Baufix is available in 50, 100, or 200-liter (13, 26, or 53 US gallons) sizes. Does anyone know if the 100-liter (26 US gallons) size is sufficient for the above application? Or would it be better to choose a larger size so the pump doesn't have to run as frequently?

We installed a sump pump decades ago as a retrofit.
Here is a brief description of how it was done.
Since the basement floor was only a few centimeters (1 inch) of concrete, it was easy to carry out.
Simply dug a hole estimated to be about 1 x 1 x 0.9 meters (3.3 x 3.3 x 3 feet). Pipes from the sink, washing machine, existing basement drain, and a piece of pipe (for the hose to the wastewater line) were laid to the hole. Formwork was placed, and concrete was poured. After it was finished, the formwork was removed, a wastewater pump was connected via hose to the wastewater line, and the pump was placed on a brick in the sump. The hole was then covered with a galvanized walk-on plate, and the job was done.
Depending on how much laundry is done, sludge should be removed after a number of years. To do this, just place the pump in the sludge and pump it out with plenty of water.
With this size, it is even possible to enter the hole if necessary.
Construction costs were not particularly high.
Since you have to plan an appropriate opening in your floor slab anyway, I would not use it for an expensive and relatively small Baufix, but rather make a sump pump.
But that is just my opinion.
I don’t understand why the installation costs of the sump pump are higher than those of the Baufix.
