I had to return this as well, it was for a system that had multiple shower heads, I just used the one that came with the faucet handle.

I did not know Wayfair sold plumbing rough in and they beat any other price online and in stores!

Worked perfectly for our master shower.

price is great for this item

I have replaced this valve five times in as many years. Most recently, I purchased one in March 2025, and it failed in December 2025 (barely nine months later). The failure mode is identical every time: it works well for the first few months, then gradually delivers less and less hot water. I am confident the issue is the cartridge. If I starve the valve by turning on cold water at my tub (which is upstream), I immediately get full hot water again because there is no cold water available to mix. Each time I replace the cartridge, full hot water is restored. I was able to get one cartridge replaced under warranty about four years ago. Every other replacement has been out of pocket. I have attempted to obtain warranty replacements for the others, but I am consistently given the runaround, and the warranty is never honored. Compounding the issue, the shower handle assembly is clearly not designed to be disassembled as many times as required to address this problem. On one occasion, the handle set screw seized and had to be drilled out, then re-drilled and re-tapped for a larger size (which has since begun stripping again). On another occasion, the temperature limit cap (located on the tip of the cartridge) could not be removed and also had to be drilled out. This shower cartridge has been an absolute nightmare. The amount of time, effort, and money I have wasted is completely unreasonable. Delta should be ashamed to sell this product. It is clearly a flawed design, and there appears to be no viable alternative within their lineup. In hindsight, it would have been cheaper to open the wall and replace the valve with a different brand rather than continue replacing cartridges. At this point, I will have to absorb that cost as well.
