This shower is amazing! It's the best shower you'll ever try. I bought it understanding that installation can be challenging after reading the review posted above by Dale above. Because the shower is made for use in Europe, it will not fit US plumbing without special adapters. Dale posted the following in answer to another user's questions which explains it well:"[Two adapters--one for cold and one for hot--are] required to transition between 1/2" NPT (US thread configuration) to 1/2" G (European thread configuration). The German dealer cannot sell this part to US customers... The Grohe part number is 124629 and can be purchased from the Grohe US customer service center."My experience was diffferent. I was unable to buy the adapter part from Grohe USA--they told me they have no way to sell parts directly to US customers. But eventually Build.com was able to offer the part for sale for me when I called and gave them the Grohe part number (one box contains the two adapters, evidently). I believe the cost was $140. However, before I learned about that option, I purchased two 1/2" male NPT thread to 1/2" female G thread adapters here on Amazon. They were only $20 each, and worked perfectly for my shower installation.2019 UPDATE: We continue to LOVE this shower. I have had a question or two, but since the shower comes from Germany it is not supported by Grohe USA. However, the seller, "bath24 German Sanitary Shop" has been awesome. They have been extremely helpful, and promptly responsive to any questions I've had. Best shower ever!
