The shower valve is an essential part of your shower system and can make or break the whole experience. It controls the flow of water through the shower head, so your shower’s performance depends heavily on the valve behind the wall.
Because the valve sits behind the wall, it is easy to overlook and hard to fix later, so it pays to choose carefully. Below we compare nine shower valves, from simple universal valve bodies to pressure-balancing, thermostatic and digital models, and then walk through a full buying guide and a step-by-step guide to replacing a valve.

Best Shower Valve Buying Guide
A shower valve controls how much water reaches your shower and gives you control over temperature and flow. Valves come in different builds to suit different needs, and the way a valve regulates flow can differ from make to make. That is why it helps to know the key facts before you choose.
What Is a Shower Valve?
Whenever you take a hot shower, a sudden blast of cold or scalding water can catch you off guard. That thermal shock can cause falls and serious injuries, which are especially dangerous for older people and people with disabilities. Children are also vulnerable to scald burns because their skin is thinner than an adult’s.
A shower valve helps prevent that. It regulates the water, minimizes fluctuations in flow and temperature, and delivers a steady, comfortable stream.
Things to Consider When Buying a Shower Valve
You will use your shower valve every day, so it should meet all your requirements. Think about these points first.
Type of valve.
- Thermostatic valves are ideal when you want water at a constant temperature. They are designed to eliminate the fluctuations caused by flushing a toilet or running a tap elsewhere in the house, which protects you from thermal shock and scalding. A two-handle thermostatic valve uses one handle for temperature and one for on/off; once the temperature is set, it stays the same each day until you change it. Most also include an anti-scald device, which makes them a good choice for families with children. A three-handle thermostatic valve adds a second outlet control, which is useful if you want a body jet alongside the main shower head.
- Pressure-balance valves maintain steady water pressure by compensating for fluctuations in supply, so the output stays steady even when another fixture is used. They are well suited to homes with unsteady water flow.
- Manual valves are the most common type. A single handle controls both temperature and flow, like a mixer tap. They do not compensate for changes in water temperature, so they carry a greater risk of thermal shock and are not ideal for households with children.
Design and finish. Valve trims come in many finishes and designs, from basic to elaborate, so you can match almost any bathroom style.
Size. Valves come in a range of sizes, so choose one that suits both your bathroom space and your shower system.
Budget. Price depends on functionality, build and appearance. Valves with longer warranties tend to cost a little more but give better peace of mind. Super-cheap valves can break easily or be faulty, so it is usually better to avoid them.
How to Mount or Replace a Shower Valve
Installing or replacing a shower valve is not too complicated when the pipes are copper or plastic. If your home has very old galvanized steel pipes, get professional help. Replacing a valve has two phases: removing the old one, then installing the new one.
Removing the old valve
- Remove the handle. In most valves a screw sits beneath the handle cap. Remove it with a screwdriver, or an Allen wrench for some makes, and the handle comes off.
- Remove the trim plate. A couple of screws hold the escutcheon plate. Unscrew them and pull it off, cutting away any caulk with a utility knife first.
- Open the wall. Make an access hole large enough to remove the valve, but keep it as small as possible.
- Remove the valve. Depending on the model you may need to cut the old valve out with a copper tubing cutter or mini-hacksaw. Make sure the water supply is completely turned off first.
Installing the new valve
Once the old valve is out, clean solder and burrs off the copper pipes with sandpaper, then follow these steps.
- Separate the valve. Remove the housing and plastic cartridge so they are not damaged during soldering, and put the cartridge back afterward.
- Make any adjustments. Depending on the model, adjust the valve before it goes into the wall, and cap it properly. Follow the instructions in the manual for soldering copper.
- Position the valve. Placing it in the wall can be awkward, so work carefully. Tie a thread or wire to the valve so you can retrieve it if it falls into the wall.
- Solder the connections. Be alert to avoid starting a fire, and keep a spray bottle or fire extinguisher nearby, especially if this is your first time soldering. Work on one joint at a time and use a mirror to check the back of each joint.
- Let it cool. Let the solder and pipes cool before reinstalling the cartridge, then turn on the water and check the valve and the shower riser for leaks.
- Finish up. Screw the trim plate back on, refit the handle and make sure everything is tight.
Thermostatic Shower Valves Explained
Many different valves are on the market, from simple slider-rail kits to fixed heads, body jets and massage jets, so decide which features you want before you choose.
- Twin shower valve: controls a single shower function, either an overhead shower or a slider-rail kit, but not both at once. It has two handles, one for temperature and one for flow.
- Twin shower valve with diverter: lets you switch the water between two shower functions, such as an overhead shower and a slider-rail kit. One handle controls temperature and the other controls the diverter.
- Triple shower valve: supplies two functions at the same time, such as an overhead shower and a slider-rail kit. One handle is for temperature and the other two are flow controls.
- Triple shower valve with diverter: can supply three functions, such as an overhead shower, a slider-rail kit and body jets, with handles for flow, the diverter and temperature.
Concealed or exposed? A concealed valve hides all its working parts, usually behind the wall, for a clean, fresh look. An exposed valve leaves the parts visible, which can make a feature of them. The choice is purely a matter of taste.
The Benefits of Thermostatic Valves
A thermostatic valve lets you set the temperature yourself and keeps the flow steady, which is a real advantage if you have small children or older people in the family. For valves it is usually better to invest a little more in higher quality, because the valve will last longer, and a thermostatic valve is a particularly good choice for the whole family.
