GROHE 35026000 Grohflex Universal Rough-In Box for Bathroom & Kitchen Faucet Installation - Durable Plumbing Fixture for Easy DIY or Professional Use

Very happy with the quality and function of this rough-in box. The problem I had when I started, as a novice homeowner, is figuring out what the heck I needed to use for my shower. I will not claim to be an expert, but I will say with a high degree of certainty that this rough-in box works well for my shower-only, when coupled with the GrohFlex controls that you also have to buy. Keep in mind that while the choices of fixtures seem endless, there is really only a few choices or designs of controls that work with this particular rough-in box -- I think.The documentation and directions that come with the box are poor to non-existant. As a novice homeowner, with zero experience with shower fixtures, I did manage to install it easily. I posted a video of my novice perspective on YouTube. I will put the like below, but not sure whether it will work. If not, search "novice GrohFlex installation" and it should come up on top of the page.https://youtu.be/QYcpjk5TZjI
