Best Rough Plumbing Valves of 2025

"I found this valve to be a great replacement for my old, problematic one. I was relieved that I didn't have to replace it after all. Using white vinegar to clean the old valve saved me from expensive plumbing work!"

"I appreciate the soldering options with this valve. It allows me to control the installation depth perfectly. The quality is impressive, and I plan to switch out all the valves in my house to Delta."

"Initially skeptical due to the price, I was pleasantly surprised. Several plumbers agreed on its great quality, and it fits various affordable trims. I hope they continue producing this model for years!"

"I find this Delta valve body to be THE STANDARD for shower valves thanks to its great build quality, packaging, and instructions."

"I installed the shower valve body, but it started leaking after a few uses. Even though I followed the instructions carefully, the valve doesn't seem to seal properly. I'm really disappointed with the quality and can't recommend it based on my experience."

"I purchased this and received it next day as I couldn't find it anywhere else without waiting 2 weeks for delivery. None of the box stores had them in stock, and it was the same price."

"I loved the idea of being able to isolate water from the cartridge directly from the valve instead of shutting off the water to my house. They are easy to use and access. The finish on this valve is superb, and everything was smooth and clean."

"This kit did not include the service stop hardware. If it was supposed to be included, it was missing from my order."

"I've always found Delta products to be well made, and this valve is no exception. My contractor installed it easily, but I could have done it myself."

"I chose this valve for its great water pressure and beautiful diverter functionality. The one-piece design for mixing and diverting works perfectly."

"This valve is perfect for my zero entry shower remodel. I love being able to use a handheld shower on a grab bar. Just remember to use the same brand trim for the diverter!"

"I purchased this valve for our guest bathroom and had a contractor handle the installation. Although we don't use this bathroom daily, the valve works well when we do. It's easy to operate and adjust the temperature. I hope it lasts for many years, so I’m giving it a 5-star rating!"

"As a plumber with over 30 years of experience, I can confidently say that the Moen PosiTemp shower valve is my favorite. It has a low failure rate and is easy to repair. Plus, the customer service is excellent, providing replacement parts quickly. The only thing to watch out for is the integral stops; they might not always align correctly. Still, I think it's worth 5 stars."

"I didn't know about temperature control mixing valves until renovating my bathroom. The new plumbing code requires these to prevent burns. The rough-in valve works great with the Posi-temp valve trim kit. I had no issues during installation, and the temperature control is excellent, providing peace of mind."

"I learned a lot from others' reviews, so I wanted to share my experience with my recent bathroom remodel. I found that anything behind the wall is crucial, as failures can lead to significant costs and headaches. I decided to build my own set instead of going for a cheaper option. I chose the MultiChoice Universal Integrated Shower Diverter Rough, and it operates smoothly. Although I only have two shower applications, I appreciate the functionality of my setup."

"After having another one of these for 8 years, I can say it works flawlessly. Despite living in an area with high lime water, I haven't experienced any issues. My wife can turn on various appliances without affecting the shower temperature, which is a huge benefit. Although the cost is high, the lifetime warranty gives me peace of mind."

"I bought this valve for my basement finishing project, and it was installed by my plumber. Initially, I faced a defect with it. However, I later discovered that the problem was in the cartridge that came with the Delta control face unit. An O-ring was broken, preventing the water from turning off. Luckily, I figured it out without having to remove the valve. I recommend checking the cartridge O-rings before installation."

"Installation was straightforward. I made sure to follow the instructions to flush the valve and prevent leaks. I mounted the valve on a 1x4, which gave me about 1/4” space between the handle and trim. The flow is comparable to my old two-handle faucet and it’s been working great. I also appreciate how easy it is to service if needed!"

"I replaced a Delta valve at my daughter’s house and found Moen to be a breeze to install. The replacement cartridges are much simpler to handle. Moen has become my go-to brand for plumbing valves; I’d give them a 5-star rating if I could guarantee a 6-year problem-free experience!"

"After replacing a leaking shower valve for a friend, I realized that accessing the valve was the biggest challenge. The old valve was leaking, but with the right tools, I was able to replace it with a solid unit that works great now. The water flow has vastly improved, and my friend is very satisfied!"

"I needed to control three outlets, and the 6 setting valve is perfect. It diverts water quickly and feels very solid without any loose knobs. I'm really pleased!"

"I found this valve to be well made with solid brass construction. It came with great instructions and was easy for me to install. Definitely good value for the money!"

"Installation went smoothly. The brass body is solid, and it was easy to assemble. I appreciate the high flow rate and clearly marked connections."

"I've been using Delta diverters for 12 years on my renovation projects, and I can't recommend them enough. They offer a great selection of trim packages and are of excellent quality."

"I recently tackled a shower installation, and while I had to knock out a tile wall, once I got to the plumbing, the installation was straightforward. So far, there have been no leaks after a month of regular use!"

"I needed a tub/shower body for my basement renovation. After receiving the correct model, installation took about 15 minutes, and I found it incredibly easy to use. The packaging was even recyclable, which I appreciate!"

"I found the quality of the brass rough-in fantastic. It has integral stops, which is convenient because I don't need to shut off all the water in the house for repairs. I easily connected it with Copper, PEX, or threaded pipe. Just a tip: make sure to remove the stops before soldering to avoid damage!"

"I did my homework with the documentation included in the trim kit. The valve cartridge I discovered has part # M954803, and it works perfectly. The valve feels solid and has no wiggle at the stop, which I really appreciate. I hope this information helps others since the documentation could be better!"

"I love American Standard products! I had a Grohe valve that didn’t fit my existing setup, but luckily, the American Standard valve was a perfect match. I’ve even replaced all my toilets with this brand, and I couldn't be happier."

"I am absolutely thrilled with the rough in valve I installed in my bathroom. The quality is evident from the start - it's robust, well-designed, and built to last. The installation was surprisingly straightforward, and the comprehensive instructions made the process a breeze. Since its installation, the valve has performed flawlessly, delivering consistent water pressure and precise temperature control. It has significantly enhanced my daily shower experience, making it more enjoyable and efficient."
