Precision engineered in Canada, Riobel own the patent to the revolutionary R23 thermostatic / pressure balance valve, which is used on all of our 1244 and 323 shower kits. This innovative design offers the best of both worlds: stabilising water pressure for steady temperature performance even in the event of a 50% drop in pressure. Temperature control, flow control and divert options are all controlled from the same beautifully designed trim, making it effortless to use and guaranteeing a luxurious shower experience every time.

The R23 valve is enclosed in an Installation Box to provide extra protection against water leakage. The addition of a rubber membrane creates an additional seal between the wall and the valve. The R23 with Installation Box can be pre-installed, providing flexibility to select and fit the shower kit later.
