About 4 years ago we decided to add a completely new bathroom downstairs. The toilet connections already existed but the shower and sink lines did not. We had these guys come in and install the toilet and shower connections as well as a stop valve on the main sewage line to stop overflow as we have a guest house on the line behind the main house. Overall the shower does work great, but the sink has some problems with the hot water and the overflow valve did not work on our last blocking of the sewage line as mentioned in another review. Otherwise though the setup does seem pretty nice.
