This Hansgrohe iBox can supply multiple shower outlets, including a shower head, tub spout, and handheld shower wand. Its PVC housing was designed to help reduce in-wall vibrations and noise, allowing for a quiet and relaxing shower. However, it does require a trim kit, so you'll need to buy and [install shower valve trim]() separately. **Get the Hansgrohe shower valve at** [**Amazon**]()**,** [**Lowe's**]()**,** [**The Home Depot,**]() [**Build With Ferguson**]()**, or** [**Hansgrohe**]()**.** The Grohe Pressure Balance Rough-In Valve is a worthy contender for anyone on the hunt for a quality sThe Grohe Grohsafe pressure-balance rough-in valve is a worthy contender for anyone on the hunt for a quality shower valve at an affordable price. It has 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, there’s a plug to seal off the other outlet. This pressure-balance valve works with any Grohe trim kit, though no kit comes with purchase. 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. **Get the Grohe shower valve at** [**Amazon**]()**.** Dialing in the perfect temperature is now easier.

It uses a thermostatic shower mixer valve to adjust for consistent temperature and installs easily in a standard 2x4 stud wall. 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 necessary power supply unit, though users can also upgrade to a separate battery backup if desired. **Get the Moen shower valve at** [**Amazon**]()**,** [**Lowe's**]()**,** [**The Home Depot**]()**,** [**Build With Ferguson**]()**, or** [**Moen**]()**.** Whether upgrading an old shower or installing a new one, consider the Delta Faucet Ashlyn shower faucet. This pick is sold as a complete kit, meaning 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—Venetian bronze, matte black, stainless, and chrome—to suit your bathroom's decor. The 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. Its pressure-balance functionality maintains a set temperature within plus or minus 3.6 degrees, eliminating the negative effects of flushing toilets or using washing machines. This valve only features one outlet, however, so it’s only suitable for showers. **Get the Delta Faucet shower valve (various finishes) at** [**Amazon**]()**,** [**Lowe's**]()**, or** [**Wayfair**]()**.** Shower head valves can be finicky, especially in homes with hard water. If your diverter valve isn’t working properly, it may be time to upgrade to this model from Mingor-Style, which features durable one-piece brass construction that can withstand hard water situations. It comes with the necessary O-rings for installation and is available in four finishes to match chrome, brushed nickel, matte black, or oil-rubbed bronze shower trim. 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. Keep in mind that this valve doesn’t mix hot and cold water, however, so a basic shower valve kit is still necessary. **Get the Mingor-Style shower valve at** [**Amazon**]()**.** Kids forgetting to turn off an outdoor shower can turn into a disaster for the wallet, and it’s especially bForgetting to turn off an outdoor shower can be disastrous, especially for those using well water or living under drought conditions.

After releasing the chain, it automatically shuts off to conserve water. This valve's brass construction and chrome finish make it a durable choice for outdoor applications. It features a 0.5-inch inlet and outlet, allowing for direct installation of most water-supply pipe fittings. Pro tip: Be sure to drain the outdoor shower’s pipes before winter and install a catch to hold the pull chain open to lessen the chances of a pipe bursting. **Get the EZ-Flo shower valve at** [**Amazon**]()**,** [**Lowe's**]()**,** [**The Home Depot**]()**, or** [**Walmart**]()**.** TThose looking for a stylish upgrade for a clawfoot tub or luxury shower should check out the Kingston Brass wall-mount tub faucet.

It has two stand-alone valves for adjusting to the perfect temperature and features a built-in tub spout with a 59-inch shower wand that rests on the spout. It comes in nine finishes, including chrome, matte black, brushed nickel, and antique brass. Though this model looks charmingly old-fashioned on its surface, it still features a durable all-brass body (regardless of finish) and drip-free quarter-turn valve cartridges, helping to avoid the small leaks for which older tubs are notorious. **Get the Kingston shower valve (various finishes) at** [**Amazon**]()**,** [**Wayfair**]()**,** [**Build With Ferguson**]()**, or** [**Kingston Brass**]()**.** ## [Jump to Our Top Picks](<#recap>) ![shower valves in a white bathroom ]() *Photo: Amazon* ## How We Chose the Best Shower Valves To create a list of the best shower valves, we performed extensive product research, drew upon our team's DIY plumbing knowledge, and spoke to Sam Chmielarski, licensed plumber and owner of [Full Flow Plumbing and Drainage](). After identifying dozens of potential options, we narrowed our recommendations to just seven based on features, materials, and overall value. The resulting list is made only of models we'd feel good installing in our own homes and suggesting you use in yours. ## What to Consider When Choosing a 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. ### Type Generally speaking, there are three basic types of shower valves: diverter, thermostatic, and pressure-balancing. Each works differently, so it pays to understand them before purchasing one. - Diverter valves are simple devices that control the direction in which the water flows, such as through the wand or out the [shower head](). Installing a shower diverter valve is typically relatively easy. - 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, a pressure-balancing valve will automatically change the hot water pressure coming from the [water heater]() to match and maintain the same temperature. - Thermostatic shower valves work similarly to pressure-balancing valves, except they maintain temperature, not balance. These valves have basic thermostats within them that allow the user to adjust the water temperature more accurately and consistently. There are also stand-alone [shower faucets]() with individual valves for hot and cold water. These valves are much simpler, though often more expensive. It's also important to know that the term “rough-in” refers to the shower valve cartridge itself, which the plumber installs during the rough-in phase of construction. A rough-in valve won't have trim kit components, such as the ring plate, handle, or other finished fixtures. ### Outlets Shower valves have varying numbers of outlets. Since each outlet will feed a fixture, having the proper number is important. For example, folks with a simple shower head can get away with a shower valve with 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 enough outlets for the plan at hand, allowing DIYers to build the shower of their dreams. ### Material 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. ## FAQs If you still have questions about choosing the best shower valves, the following answers to common questions should help. ## Author Tom Scalisi is a freelance writer, author, and blogger with a passion for building.
