    Quick and easy install
    [This review was collected as part of a promotion.] Love this brass body makes it feel like excellent quality. The install was easy to do and wasnt confusing, pretty simple setup but works like a dream conoared to the one i had in there before. The test worked well so i moved to install my trim.

        Excellent shower valve body of great quality
        [This review was collected as part of a promotion.] This American Standard shower valve body is easy to install for the rough-in assembly when remodeling a shower. The male threaded ends makes it easy to to atrach female fittings or to do the other way of sweating in pipe on any of the ends. So the balve body gives you two different ways you could go about installing the valve body assembly. The brass assembly is very strong and durable, not of cheap quality at all. I have installed many valve bodies like this one before ss a professional plumber and it is one of the best ones you could get, especially with the different ways there are to install it. The lock in plug is good to have instead of putting the actual cartridge in to.make it easier for rough-in plumbing inspections. American Standard has always made great products, and this is judt another one of the high quality excellent products that they make.

            Quality made
            [This review was collected as part of a promotion.] Looking forward to years of reliable preference from this quality made universal shower valve. The product is made of brass with great accuracy on each thread insuring years of No- leak service usage.

              Excellent solid brass flash shower rough in valve
              [This review was collected as part of a promotion.] Solid construction. Well built and beautifully packaged. Operates with ease and precision. The solid brass components were clean and burr free in regard to the threads. Easy to install. The flow valves worked well, no catch when switching from hot to cold, on to off.

                Good function, but packaging needs some work
                [This review was collected as part of a promotion.] This valve works well when paired with my Edgemere Trim kit. Installation was made more difficult in that the plastic wall guide was damaged in shipping. The ceramic valve works smoothly, with no "flex" at the stop. Definitely a quality build and will likely last for some time.

                    Quality material and fit; stress-free installation
                    [This review was collected as part of a promotion.] So very pleased how stress-free and simple it was to install the Flash shower valve with my shower faucet kit when I upgraded my bathroom with a more modern design. The quality and fit and finish of the water inlet and outlet is of the highest quality. The high brand quality provides me with reassurance that it will last forever and not cause any problems down the road.

And seems to deliver amazing water pressure at uniform temperatures, unlike other brands this product was built using high-quality materials and should last a very long time!

                          [This review was collected as part of a promotion.] This neat little valve works perfectly with all the other compliments of the rain shower system to create the perfect amount of water flow through the shower head to create the desirable amount of water for your shower.

                            [This review was collected as part of a promotion.] Fits perfectly on the faucet that we received. This was an extract fit and we couldn’t be happier with how it looks in our brand new bathroom. Works perfectly as described and a necessary piece to the new shower.
