GROHE 29142000 29142 Square US Thm Smartcontrol 3

Very impressed. Replaced my old shower valve with this excellent shower valve and surprised at how much better this is. Easy to install, simple operation with great control of temperature and flow rate. The quality represents great value. I'll stick with Grohe in future.

Purchase on Amazan since local grohe dealer do not bring in three way control. At first i was hesitant to buy from Amazon wondering would the product would be okay. But my fear was unfounded and ordered. Because i knew if any thing wrong i can always return, as Amazon is not like other online. Its true. I got it although i paid little more. Very happy. Lical plumber did the installation works wonderful

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 gpm Euphoria 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 the easiest installs for a shower valve in the market. Well thought out as it fits to any rough in depth. Seals perfectly and the final product is great. Highly recommended

My plumber is not able to install the thermostat dial because the grey part given is too short. According to plumber, I need the longer one and the part given is short. Apparently, I need part C. This item is not cheap on its own and it is purchased with the Smartbox. Please help me resolve and send me the right part. I don't want to give you a low rating really cause you have not denied me assistance yet. But I need to give some rating to get this message to you.
