If youre looking to upgrade the look of you shower area, this is it. Very sleek looking product and works exactly like you want it to. I cant speak to the install process on an existing bathroom because we installed in a complete gut job renovation project and routed all of the plumbing accordingly. Super easy to install though with the plumbing roughed in. The amount of options for waterflow is fantastic. We wanted to have multiple jets and options for the shower but didnt want to route plumbing everywhere - this is the solution. Super easy hook up, ease of use with the built in diverter, youll be experiencing heavenly rainfall showers in no time!
