Our shower mixer unit failed in the guest bathroom, and as it was installed behind a tiled wall I was looking for ways to not open up the wall too much - There was pretty much no way to replace the tile. Although this is not a simple installation, you might want to bring in a plumber if you aren't quite handy with your tools, it also isn't really too complicated either. Replacing the mixer would have been a lot more work, so that was a huge plus point for me. This is made with good quality materials for the price point, it works very well, and with minimal effort, we have a fully functioning guest bathroom again. And one that came with a much better shower system than previously.
