Best Shower Valve


The shower valve is the component of a shower that controls water temperature, and the slightest movement one way or the other can be the difference between scalding and frigid. Choosing the wrong valve—or worse, a low-quality product—can result in a poor fit and may lead to leaks. Shoppers also want the valve to suit their style and moderate temperature to meet their specific needs.

Whether it’s a simple replacement, a valve that ties in with a smart device, or even a vintage-looking setup, keep reading to find shopping tips and a model that will work for almost any situation.

What to Consider When Choosing the Best Shower Valve 

Believe it or not, there is more to a shower valve than simply twisting a knob and letting the water flow. The following are some of the most important considerations to keep in mind when choosing the best shower valve.


Generally speaking, there are three basic types of shower valves: diverter, thermostatic, and pressure balancing. They each work differently so be sure to understand them before purchasing a shower valve.

  • Diverter valves are very simple, as they choose the direction the water flows. These valves are in control of whether the water will exit the wand or the shower head. Diverters are typically simple to install as well.
  • Pressure-balancing valves can sense a drop in hot or cold water pressure and adjust the opposite pressure to match and maintain a constant temperature. For instance, if someone flushes a toilet and the cold water pressure drops, it will automatically change the hot water pressure to match and maintain the same temperature.
  • Thermostatic shower valves work similarly to the pressure-balancing valve except that they maintain temperature, not balance. These valves have basic thermostats within them that allow the user to adjust the water temperature more accurately and with better consistency.

There are also stand-alone shower faucets with individual valves for hot and cold water. These valves are much simpler, though often more expensive. Also, the term “rough-in” refers to the shower valve body itself, which the plumber installs during the rough-in phase of construction. It doesn’t have trim kit components installed, such as the ring plate, handle, or any other finished fixtures.


Shower valves have varying numbers of outlets. Since each of those outlets will feed a fixture, it’s important to have the right amount.

For example, folks with a simple shower head can get away with a shower valve that has just one outlet. Those with a shower head and spout will need two outlets. Those with body jets will require three outlets, and so on.

It’s best to come up with a plan for the shower before choosing the shower valve. This will ensure that there are enough outlets for the plan at hand, allowing DIYers to build the shower of their dreams.


Shower valves are typically tucked behind a wall somewhere with relatively limited access. For that reason, it’s important to ensure that any valve chosen features durable materials that will last for years.

The best material for plumbing fixtures is almost always brass; it’s durable and doesn’t rust. Next, look for copper shower valves. Worry less about plastics and more about the metal materials housing the cartridges that adjust the temperatures.

This Hansgrohe can supply multiple shower outlets, including a shower head, tub spout, and a handheld shower wand. Plus, the PVC housing was designed to help reduce in-wall vibrations and noise as well, allowing for a quiet and relaxing shower. However, it does require a trim kit.

Best Bang For The Buck

Best Shower Valve GROHE

The Grohe Pressure Balance Rough-In Valve is a worthy contender for anyone on the hunt for a quality shower valve at an affordable price. This pressure-balance valve works with any Grohe trim kit. It comes with two inlets for hot and cold water and two outlets for a shower head and a tub. For those who prefer to use just the tub spout or shower head, however, there’s a plug to seal off the other outlet.

This shower valve has a wide range of temperature adjustability, rotating 265 degrees between handle stops so users can make small adjustments. It also has built-in check valves to prevent back-feeding hot or cold water into the other line. For maintenance, the Grohe features two built-in shutoffs for working leak-free within the wall. Keep in mind that it does require a trim kit.

  • Outlets: 2

The Moen Smart Shower Digital Thermostatic Valve lets users adjust shower temperature digitally from their phone when paired with a Moen Shower Smart Controller. This shower valve has 0.5-inch inlets and outlets, and it will work with both the tub spout and shower head (or a handheld shower in place of the spout). It also comes with a 30-foot-long data cable and the power-supply unit, though users can upgrade to a battery backup separately, as well.

While a controller is sold separately, the S3102 is the foundation to build a smart shower system on. It uses thermostatic valves to adjust for consistent temperature, and it installs easily in a standard 2×4 stud wall.

Best with Showerhead

Best Shower Valve Delta

Whether upgrading an old shower or installing a new one, consider the Delta Faucet Ashlyn Single-Handle Shower Faucet. As a complete kit, it includes the necessary components to revamp current shower trim, including a pressure-balance valve, a shower head, a tub spout, and hardware. It comes in four different finishes—bronze, matte black, stainless, and chrome—to suit the decor of the bathroom.

The Delta Faucet rough-in valve itself features universal 0.5-inch inlet and outlet fittings, allowing users to replace most older valves without coupling up or down in pipe size. The pressure balance works to maintain a set temperature within plus or minus 3.6 degrees, eliminating the negative effects of flushing toilets or using washing machines. Do note that this valve only features one outlet, however, so it’s only suitable for showers.

Product Specs

  • Type: Pressure balancing
  • Outlets: 1
  • Material: Brass


  • Available in multiple finishes
  • Universal fit for simpler installations
  • Maintains temperature within 3.6 degrees


  • Only 1 outlet

Best Shower Arm Diverter

Best Shower Valve Brass

Showerhead valves can be finicky, especially if a home has hard water. If a diverter valve isn’t working as it should, it may be time to upgrade to the Brass Shower Arm Diverter Valve from Mingor.

For users who don’t already have a separate shower wand, this diverter valve allows for an easy installation, as it threads onto the pipe behind the shower head. When the handle is 180 degrees backward, all of the water will flow to the wand. When it’s 180 degrees forward, all the water will exit through the shower head. At 90 degrees, it mixes both outlets equally.

One-piece brass construction makes this model long lasting and durable against hard water situations. It comes with the necessary O-rings for installation and is available in three finishes to match chrome, brushed nickel, or oil-rubbed bronze shower trim. Keep in mind that this valve doesn’t mix hot and cold water, however, so a basic shower kit is still necessary.

Product Specs

  • Type: Diverter valve
  • Outlets: 2
  • Material: Brass


  • Available in 3 finishes
  • 3-position handle for shower, faucet, or a mix of both
  • Durable 1-piece brass construction


  • Only a diverter valve—it does not mix temperature or balance pressure

Get the Mingor shower valve on Amazon.

Best For Outdoor Showers

Best Shower Valve EXFLO

Kids forgetting to turn off an outdoor shower can turn into a disaster for the wallet, and it’s especially bad for those on well water or living under drought conditions. This stand-alone EZ-Flo self-closing shower valve installs directly in line with an existing shower head and will operate as long as there is tension on the pull chain. After releasing the chain, it shuts off and conserves water, making it ideal for homes in areas prone to drought or with older well systems.

Brass construction and chrome finish make it a durable choice for outdoor applications. The 0.5-inch inlet and outlet make it a direct installation for most water-supply pipe fittings.

Pro tip: Be sure to drain the outdoor shower’s pipes before winter sets in. Install a catch to hold the pull chain open as well, to lessen the chances of a pipe bursting.

Product Specs

  • Type: Stand-alone
  • Outlets: 1
  • Material: Brass


  • Automatically shuts itself off
  • Universal 0.5-inch threads
  • Protects drought-prone areas


  • Needs a hook to catch the chain to prevent freezing

It comes in several finishes, including chrome, matte black, brushed nickel, and antique brass.
