We have our bathroom renovated and made us an elegant faucet from Villeroy & Boch. Unfortunately, the water jet was not what you would expect from a designer faucet. The size of the mixing nozzle is unfortunately exotic and not to be found in the construction market. So I ordered from Amazon. The new nozzle was screwed and the result was a soft water jet. Our tap water is of high quality and not at all calcareous. Mixing nozzles can be unscrewed easily even after prolonged use. Due to the relatively high price, there is only 4 stars. Against the plastic material I have no objection. Previously, these parts made of metal, but the rotten lot faster in my estimation.
