    90s Grohe & Hans Grohe WERE high quality in the late 1980s, but got "competitive" more plastic..In the early 90s.  I'm a Kohler guy or some of the real high end stuff like Dorn Beach and custom brass places.  Mad Dog 🐕

    The race to the bottom is about over. Its all junk. We installed a couple of Rohl rough in valves last week. No instructions, no markings to indicate depth in the wall.

    Moen is complete garbage.

    Kohler isnt much better.

    Symmons shower valves. So far so good. Have repaired and installed thousands. They are the inventors of anti-scald technology that all other companies use now. Not exaggerating. Use them with confidence.

    I have installed Grohe Rapido and haven't had any problems. There are a bunch of videos on You Tube to help you do it correctly.
    Plastics have become an important method of keeping prices low and competitive. You can thank your local inflation creator for the trending 'make it cheaper' and give it a one year warranty business model. Expected replacement???--One Year and a Day!
