M-core is a shower design for your time. This valve system is simpler and faster to install and offers additional functionality with desired style choices to create an ideal shower environment. Moen has conducted extensive research to create M-core, and what drives the design is a passion to make the workday more streamlined for plumbers, and to give more freedom in showering functionality and design for both new construction and remodel projects. Homeowners and designers will enjoy M-core's improved style and finish options, including perfectly matching mixing and transfer trim, and refined details that provide the finishing touches to a dream bathroom. Once installed, M-core valves, with new 3-series trim, have pressure-balancing capabilities designed to control temperature fluctuations in the event of water pressure changes in the home. They also feature volume control, allowing you to adjust the flow of water.
I would give 5* for this product as I love the look and feel and it works great, but it arrived with a missing screw. Wayfair was very understanding and offered us a partial refund or store credit. This faucet lifts to control the volume (water flow) and turns left and right to control the temperature. Many shower faucets only allow temperature control so if you want flow control as well, this is the one for you. This product is the trim only, i.e. the part that you see and use every time you shower. It does not include the valve (piece that goes inside the wall). You have to buy the valve separately which costs around 60-70 depending on where you get it from. Make sure you get the correct valve. It must be a Moen valve but not all Moen valves will work. For this faucet you need a M-core 3 series valve with 3 ports (if not connected to a bath) or 4 ports (if connected to both a shower and a bath). You also want to make sure you select a valve with the right connection type (PEX vs CCIPS). Your plumber should be able to help you select the right valve but Wayfair should add this information on the product’s description page. Otherwise it’s a great product of great quality with a lifetime warranty.. Anonymous. Sat May 03 2025
