Grohe 29141000 Grohtherm SmartControl Thermostatic Trim, Starlight Chrome

Great product, excellent quality, it’s an EXPERIENCED installers DREAM....(I am a “plumber/contractor”)If you do it once, you will never look at it as a “challenge” again.The superior German engineering shines through on every bit of this valve.The Grohe rapido box required (pt# 35601) to install this 3 way diverter valve is where the whole job comes together.A 2x4 Wall with the the center stud notched to receive a 1x6” piece of pine Board is all you need to secure the rapido rough box.Level it, Screw it, done... easy.Connect the water with 3/4 full size female adaptors (if you can)... Bring 3/4 to the inlet of this valve.... period..(my recommendation) The stability/volume of flow when running all ports at once will really be worth it..I’m at a cumulative 3 fixture 10 gpm flow rate @ 55 psi street side water pressure.I have all grohe shower heads with 2 max flow ratings at 2.5 gpmEuphoria cube (shower head)Grohe mono 310 (shower head ceiling)Plus a grohe “cube” spray at 1.75 gpm.All purchased on Amazon.Tile redi shower pan 32x60 w lineal drain also purchased on amazon(Tile installer notice)Tile cut dimensions should be cut very tight to this box. The trim is not very large, and you will see a cut that is spaced any further than 1/4” away from the blue rapido box. Trust me on this! See pic..Avoid the integral stops if you can..They are cheap plastic, and not worth what a few ball valves can do in an access panel or basement access.Installing the the valve internals into the body is straight forward. Just take your time..make sure the volume knob splines get trimmed to the face of the orange jig caps, no more, no less..I’ve installed 100’s of showers, I used to only recommend the symmons temptrol, but now I recommend this valve for high end applications only.It’s very durable, and when piped correctly you will be impressed with the volume of flow and pressure this valve can produce.Your only problem following this install should be the annoyance of running out of hot water!

One of my valve cartridges was bad out of the package, and the whole unit was installed in my wall making a return impossible. So I had to call Grohe customer service to get the cartridge replaced.They picked up the phone immediately with no hold time whatsoever. After confirming a few basic details, they quickly shipped me a new valve cartridge with absolutely no hassle. For this sort of product customer service is super important since you can’t tear it out once it’s installed, and these guys are easily the best at that.As for the product, it works exactly as advertised. I just wish they had clearer instructions on how to calibrate the temperature, but there are some good YouTube videos on that and it’s very easy once you know that you simply need to pry out the grey inner piece till it’s free from the dial, then rotate the temperature valve with a screwdriver until it is set up the way you want it. Then simply push the grey piece back in.

We love the simplicity of this product, controlling water with a push of a button;)Water pressure is also easy to adjust by turning the knob and there is enough pressure for all faucets to work simultaneously.

Had to replace a mainstream US-brand shower valve that was leaking and stuck. Chose to add a handheld shower at the same time. The Grohe products are great quality and engineering. The shower controls are intuitive to use.The only deficiency that I'd like to point out is that their YouTube installation videos do not reflect the same product version that I received. Make sure to follow the printed instructions that ship with the parts. Learned it the hard way.

I knew this was the diverter/controls for me the minute I laid eyes on it: all in one -- not multiple knobs and temp controls -- and thank the lord, no pull-up diverter on the tub spout (my old set up never really worked correctly and broke twice in 9 years). The Grohe is BEAUTIFUL, flexible, and simple to operate. I'm very happy with mine.Now comes the "But..."1) Be warned, installation is NOT for amateurs. My very experienced plumber even said it was really fussy and complicated to put together -- lots of springs and little pieces to get in place on the trim side. I looked at the exploded schematic and it made my head spin.2) I had a a mishap with the valve (ahem, it involved a "helpful" man, a drill, and installing shelves in the linen closet behind the shower). After several panicked phone calls to plumbing supply places, a got confirmation direct from Grohe that the valve and the trim only come as one unit. You cannot buy just the valve or just the trim. So be aware, if anything happens to one part, you're going to have to pay another $400+ for the whole component. OUCH.I'm giving it 4 stars only for price, the fact you have to buy the Smartbox separately, and replacement parts are all or nothing.Otherwise I'm pretty sure it's the fanciest and nicest thing in my whole house.

Es buenísimo para la ducha, fijas la temperatura y solo tras un botos, para ducha, canilla o duchador de mano. Es Grohe!!

I ordered two of these from two different sellers. I could not figure out why when I finally was able to install this one why it would not fit properly. As seen in the picture, this unit arrived with volume stems way shorter than they are supposed to be. One on the right is the one that came with this unit vs. the one on the left that came from a different seller. Only resolution I can find is to order an extension kit from Grohe for $115.00! Not sure if this was a returned item and that is why the stems were so much shorter (they do get cut during install specific to the depth of the rough-in) or if they are just shipping an inadequate product. Buy elsewhere or confirm when it first arrives that you got the correct size for these or you will be in my situation!
