The description says 1 box and 1 of each part.There is a total of 4 screws, and 8 plastic parts.Overall ok. Seriously over priced. Would be a great item to be included in the over priced valve kit. Or at least updated instructions advising if you go past a certain point on the valve rough in you need this kit.

This is a genuine OEM part and it worked fine so I have to rate it well. The one star off is a reflection on Grohe charging an exorbitant amount for a few pieces of plastic. Absolutely ridiculous.

Title says it all. I had to have this product but didn’t know it until we went to install the trim. We followed the depth guidelines on the rough in box. They should have marked what depth the regular kit works with. Too expensive for what it is….

So, I spent +-$1000 on the state of the art Grohe shower system and despite my plumber and tiler doing good work, we just ended up short of space and needed this kit. You'd think Grohe would offer this kit at a reasonable price to support their valuable clients, but I feel like they knew we were screwed and took advantage of us by charging $110 for 4 screws and a couple of plastic extenders. Really??? $110??? That's the thanks we get?

... if you need it, you need it ... my install was 1/4" too deep so I needed the extension kit ... better too deep than too shallow I guess.

Quando il corpo del miscelatore termostatico viene installato troppo internamente al muro questo kit accessorio è molto utile e fondamentale. L'unico problema è il prezzo decisamente esagerato.

Because of the hieroglyphic installation manual, many first timers make control box depth errors causing you to by these ridiculous over priced pieces of plastic. It's sickening!

Es un producto original de grohe , y es un kit opcional pero a la vez imprescindible para poder montar el sistema de ducha que ya de por si es carisimo y no tinen el detalle de adjuntar los 4 tornillos y los 4 plasticuchos paea poder realizar el montaje completo en cualquier circunstancia. Facil de montar para manitas pero no muy recomendable para aficionados.

This item works, can finally use my shower as intended. But it is very expensive for a few pieces of plastic and some screws.

Je ne peux que mettre 5 étoiles. L'article correspond à ce qui est décrit. C'est bien pour 3 boutons. La photo pourrait le montrer et la désignation plus claire, mais oui, c'est pour 3 commandes maximum. Une fois installé, tout fonctionne parfaitement. Après, on est d'accord, le prix est prohibitif. Sur le site Grohe, il est à plus de 90€ !!! Heureusement, ce magasin en ligne le propose à un prix plus raisonnable. Mais c'est toujours trop cher. Ça ne devrait pas couter plus de 10€, mieux ce kit devrait être fourni d'origine. C'est pas la faute du vendeur qui a livré très rapidement, c'est GROHE qui exagère.
