I live in a very hard water area, the reason for the demise of my last shower, and did not want to pay a lot of money just to have another unit fur up. Could not believe how inexpensive this one was, a third of price of the one it replaced, that I had bought a replacement heating vessel for at about the cost of this Triton a couple of years ago. Anyway delivery was quick and feedback from the senders good, easy to fit just went onto the old water pipe that sticks out from the wall with two compression elbows and the electrics just the same as changing a plug. The only thing I can not comment on is the head rail, flexible hose and shower head as I left my old one in place and did not even unpack the new one to look at it. Works well, does a fine job, I would recommend this shower to anyone and think that anybody with basic DIY skills should have no trouble fitting this cheap but well built unit.
