Review on 🚿 Duttao DT5611-ORB Drill-Free Slide Bar Combo with 5-Function Showerhead and Handheld Shower, Oil Rubbed Bronze – Certified for UPC, IPC, ASME A112.18.1/CSA B125.1 Standards, WaterSense Certified by Wendy Backous

Usually you have to lay the lines for the switching/connection valve and from there to the main shower head and the hand unit. You simply screw the entire unit onto the existing shower rail and you're done! It has a built in switch button so you can choose whether water comes out of one or both heads. However, I highly recommend screwing the base permanently rather than using the supplied adhesive. Otherwise you risk the glue coming loose and the stem that connects the handle to the shower head stem breaking, as the connection point appears to be made of plastic which can break fairly easily if twisted too much. However, if you bolt it down permanently with the included bracket, it should hold up pretty well and stay strong for a long time. We have thoroughly enjoyed it for the past 3+ months of using it. My kids especially like it because they are small and it allows them to have the water closer to them.
