Bad service.

System is difficult to install. Service of Build and guidance of Build is minimal and unprofessional.

A great all-in-one valve

You can’t ask for more when you have a thermostat with built in volume control, which is very solid and reliable

Horrible design

Was very flimsy and design isn’t good. The button is flimsy and feels like it will break. Regret buying this. Will return it.

It was easy to install Grohe BAU COSMOPOLITAN BATTERY POWERED SINGLE HOLE TOUCH, it looks beautiful & elegant

Slim and Lovely

A very slim and modern approach to separately managing shower volume and temperature. Other systems are bulky (Delta TempAssure, for example) although more traditional in design.

Grohe is a really nice quality smart control. The single valve controller allows you to separately control the water temperature and flow rate. It’s great that you can set the temperature knob how you like it and turn the water on off using a button.

Beautiful brushed nickel matches my other brushed nickel fixtures. Not yellow or brassy! This is a extremely well made professional grade thermostatic mixing valve. You get the valve body and the brushed nickel trim. Don't forget you need to order the Grohe "Smartbox" separately - the description gives the part number. You also can order service shut offs separately and install them into the valve body - I suggest you do, as that lets you (or the next owner, or a plumber) turn off the water supply right at the valve to work on it if needed. Way easier than shutting water off to the whole house or searching for a buried shut-off valve.

So it's time to remodel that old shower. Now is the time to switch over to the newest tech in water delivery systems. This advanced mixing system gives a whole new world of control over your shower/bath experience. Set your water temperature and pressure, lock it in and from that point forward a single push of the center button delivers that exact setting every time. Install gains some difficulty only due to the unfamiliar way it is constructed. Recommended for those with some plumbing experience otherwise contact Home Depot for installation support.
