hansgroheRough, iBox Universal Plus with Service Stops, ¾", 01850181

Necessary if you install a thermostatic controller. Here is the retrofitted from Alt Shower who have Delta plate. It is very high quality and make sure you hire someone who knows the trade.

We recently remodeled 3 bathrooms and we are so happy with all the Hansgrohe product.This iBox is genius... To fully appreciate it, you'll need to watch a video at the Hansgrohe website where they animate this iBox for various configurations. It is just plain genius. Hansgrohe made it simple that this is the only thing you use for shower / tub connect... you want a shower only, use the iBox... you want a shower / tub combo, use the iBox... you want a hand-held shower and jets on the wall, use the iBox. You get the idea.Installation is easy but requires attention. Because this is German/European, they do things a little differently than us Americans, and thus your American (I'm assuming) contractor / plumber.First, you have to make sure that it is installed in the proper position... Although it can rotated 180 degrees without consequence, it cannot be rotated 90 degrees. There is actually the word "Top" on top, which my contractor missed. He installed the top to the right instead, so he had to re-do it.Second, all the connections are screwed / twisted on instead of solder like other brands. You'll melt the plastic if you use solder nearby! My contractor soldered all the pipe (short segment) and 90 degree bend connectors elsewhere first, and then twisted them on... this iBox looked like an octopus (with 4 legs instead of 8) when it was installed. Then you can solder those connectors to your water supply / shower / tub outlet. Or you can skip all the copper pipe and use PEX tubing instead.I bought 3 of these and am very happy. I would highly recommend watching the video at Hansgrohe website multiple times, they explain the installation and waterproofing well.

We needed to replace a 12-year old Pegasus shower body (from Home Depot) that was leaking and wanted to go with something of higher quality. Looking at the trim options from Hansgrohe, as well as reviews, we decided to go with this German brand. This valve assembly is very solid and works well so far.Our plumber recommended Delta but we couldn't find trim and faucet options that we liked. When he installed this one from Hansgrohe, he said he's pretty sure that actual cartridge *IS* made by Delta so win, win?What sealed the deal for us was Amazon's pricing which is much lower than the local plumbing supply stores. Time will tell as to whether this holds up better than the Pegasus but I am optimistic.

Every plumber I spoke too had the same response, it's the best.

Our contractor (who has his plumbing license) screwed up the installation because he didn't read the directions! We ended up having to cut out the wall behind the shower (in a closet in the adjoining bedroom) to fix a leak. If you follow the directions, this is a DIY project for the homeowner who can sweat solder copper fittings. The box IS marked TOP, but its hard to see the large letters because they are embossed as part of the shell with no paint or anything to create contrast, so pay attention to that. Also, make sure you install the box absolutely LEVEL according to the directions. This is especially important if you have, for instance, 2 levers on your trimplate placed either horizontally or vertically next to each other.

Ingenious design and method of installation but a bit complex and somewhat difficult to understand the directions.

Good design but it is tricky to install. It does not come with 3/4" to 1/2" converters.Plumber didn't want to use elbow brass fitting as they will be hard to fix at the proper direction.He used a converter then soldered elbows. This one is imported from Turkey, lacks the gasket. Had to improvise and adapt a schluter gasket by heating it to fit.

The iBox is perfect. I wish I knew about this product years ago. A must! Such a wonderful product it's a shame that I have to hid the box :)
