Review on Hansgrohe 1850181 iBox Universal Plus with Service Stops - ¾" Upgrade, 4-Inch Required Rough - 01850181 (3/4-Inch) by Benjamin Michels

I like this product! This is my first time using hansgrohe and I will not use anything else. I have a rain shower and attached hand held shower head with PEX and bought an S&E thermostatic overlay with volume control with a switch to use both at the same time (one of the VERY few manufacturers that can). I can't wait to use it. Make sure that the two shut-off valves are closed (slotted screwdriver notch points up/down). I hooked up 3/4 PEX for hot and cold water directly to it because I wanted good pressure on both shower heads once we started using them.
