Question: Is this suitable for exterior shower installation?
Document: The description of this product was somewhat misleading. the product was incomplete, missing screws, and without mention of it being sold without the wall housing, which, usually when purchasing a comparable item at a plumbing supply, is included in the price of the item. The low price reflects this omission.
The Ibox (the valve in the wall) was a pain to install b/c it is plastic and you can't solder next to it. The online videos are little help either as they are in german and don't use copper pipe that has to be soldered.The handle itself is great though. Just turn to the right and it's the perfect tempeture every time.Looks nice too!
Answer: no
