GROHE 35601000 35601 Npt US Universal Rough-in

Good price for a quality product, with lots of instructions. We still had to watch the youtube video though.

This is a review of Grohe 35601000 Rapido Smartbox Universal Rough-In Box I am installing this shower control unit in my housekeeper’s bathroom (Figure-1). It is the GROHE 24110000 Grohtherm Single Function 2-Handle Thermostatic Trim, Starlight Chrome. In order to do that, I needed the corresponding rough-in box. This particular model works with several models of Grohe shower controls. Note: Unless you have some plumbing experience, and the right tools, I would recommend having a professional plumber install it for you. The Unit (Figure-2) The unit itself has: • 3 outlets 1/2-inch female • 2 inlets 1/2-inch female, for hot/cold water supply It fits into a hole with a diameter about 5.5 inches (13.9cm) Once the unit is through the wall, and properly mounted, you can attach the input water lines, and up to three output devices. The unit can be mounted on solid and dry walls (Figure-3). As you can see, I had to remove the drywall in her closet to get to the plumbing. I plan on installing a door there for easier access. I then cut an access hole into the shower, poked the unit through, and mounted it to the back with a piece of particle board. I have roughed-in the plumbing, but have not yet connected it In this image, you can see the unit coming into the shower (Figure-4). Okay, it looks pretty messy; however, the type of shower construction used on this old shower made it almost impossible to cut a perfectly round hole without damaging the surrounding tiles. The good news is that this rough-in box is very versatile and forgiving. Once I do of bit of retiling, and add the trim piece, you will never know. And, that is this end of this review, because it is all about the rough-in box; not the shower controls. But I will say this… It is designed in an almost intuitive way, and very well built. I take my hat off to the designers at Grohe. FYI: On the seller’s page is an excellent video on this product and its installation. Happy Plumbing.

super easy to install once you understand it they have instructions and videos on installing and works perfectly .

Hello, I need to return this item because it does not have Australian WaterMark approval, and my plumber will not install it. Please approve the return and refund.

Love this type of water mixer. Pressure is good
