The poece that regulates the temperature of the water is very solid, and heavy, so it feels very strong and stiff, the other parts, are mostly made of plastic, however that’s the case for most showers in my country so it’s not surprising, what’s surprising is that there also are metal parts, quite a few which is nice. And it’s nice that it comes with the 2 adapters so i don’t have to go buy them. At the moment i haven’t installed but i’ll leave another review after installing it.
