Question: Is the handheld shower plastic?
Document: Beautiful, efficient. I'd give it 5 stars but the hand shower is plastic. For this price not only should it be ALL metal but it should get up in the middle of the night and make me a peanut butter and jelly sandwich.
It's not like an aerated faucet, it just makes it feel like a lot of water when it isn't really. Couple that with the big diameter of the main head and you've got an outstanding shower. I will recommend this to anyone who asks.
In any event, whatever minor frustrations I felt disappeared the second I stood back and looked at this handsome shower in place - and then once I turned it on all was perfect - it's terrific - but the install requires careful attention.
I enjoy the rainshower head and my wife uses the hand wand.One IMPORTANT word of advice. If you start off using one shower head and want to switch to a different one, step out of the spray of water before changing them over. The cold water still in the line to the other shower head will give you a heart attack!
The shower works great and looks even better. The installation instructions are terrible though. Even the list of required tools at the beginning is missing needed tools. The step by step instructions leave things out and you need to study the pictures to make sure you don't forget a gasket or something else. I like that you can set the temp and never touch it again. The other handle lets you select OFF, rain head, and hand wand.
This is the best shower I've ever stood under! High end hotels, multiple houses, you name it, this shower beats them all. The build quality is first class. The mixer is really solid, the fittings onto the wall stub-out are neat and fit really well, the riser and showerhead all go together perfectly.The main rainfall head is absolutely fantastic. I end up running it at less than wide-open a lot of the time as it feels like so much water.
The rough-in instruction for this are VERY precise and the kit comes with a wonderful spacer to hold everything in place. That said, there is exactly zero room for error. NOTE - (not included in the instructions) - Following buildout and tiling etc the end of the Exposed Thermostatic Basic Set must sit at 3/4&#34; from the finished wall.
God bless the plumbers referenced in the other reviews here that report zero issues on installation of this impressive and solid unit. It really is a work of art and the streams from both heads are just wonderful. I did the install myself. I'd consider myself an exceedingly capable home DIYer. I've renovated a number of homes, and installed a number of showers/baths etc etc.
Anyway - on to the install - all went well, though again lots of care must be taken to be exceedingly compliant with the directions, a 1/16 here or there can cause issues. In my unit the lock-nut for the showerhead was ceased in place - meaning I could not remove it to slip it onto the horizontal line. I tried 3 different allen keys to try to get a good fit but in the end the head stripped.
Answer: yes
