Understanding Shower Valves
Shower valves might seem relatively simple but they have some unique features that set them apart from each other. You might also see some technical terms and jargon that you haven’t heard before, such as:
- Rough-in valve: Every shower valve is equipped with a rough-in valve. It is the part that connects to the hot and cold water supplies (4).
- Mixing valves: Technically called “thermostatic mixing valves (TMVs)”, these components mix hot and cold water to achieve the desired temperature and keep it consistent throughout your shower (5).
- Inlets and outlets: Any connection that channels water must be watertight to prevent leaks. This means shower inlets and outlets must fit perfectly into your existing plumbing. The tapered threads come together to form a watertight seal (6). Ensure the size (for example, a 0.5-inch inlet) matches what you currently have.
Shower Valve Types
Thanks to technological advancements, there are now several types of shower valves to choose from. There are benefits to each of these types, with your main options being:
Digital Valves
Digital valves are very user-friendly and offer precise temperature control thanks to their digital displays. They allow you to adjust various aspects of your shower using a control panel rather than a traditional handle. This includes pressure, temperature, and which outlet you want to use if your shower has multiple.
These shower valves are among the most advanced you can buy and usually feature cutting-edge technology. Unsurprisingly, this also means they are more expensive than conventional shower valves.
They can also require extra installation work such as new electrical wiring in order to use the shower panel. You might need to purchase specific new faucets or shower heads that are designed to work with digital valves.
Pros
- Perfect for anyone who enjoys modern technology
- Very user-friendly
- Enables you to pre-program your shower
- Some digital valves can be controlled remotely
Cons
- Expensive
- Must have a compatible shower head and other parts
Thermostatic Valves
Thermostatic valves have two handles. One handle controls the water pressure, while the other adjusts the temperature.
An element (usually wax) inside the valve responds to heat. If the cold or hot water supply is interrupted, the shower is automatically shut off to prevent a sudden blast of scalding hot or freezing cold water (7).
Some models also allow you to manually set a maximum water temperature in case your hot water is particularly hot or you simply don’t enjoy very warm showers.
If you find your current shower unpredictable in terms of water temperature, a thermostatic unit is an ideal solution. They bring consistency to your time spent showering.
Pros
- Prevents hot and cold bursts if the water supply is interrupted
- Safe for everyone thanks to temperature regulation
- Provides consistency while showering
Cons
- Lacking in features compared to more advanced types
Pressure-Balancing Valves
Pressure-balancing valves have a single handle that controls both water volume and temperature. A disc or piston inside the unit maintains consistent pressure even when a water outlet is used elsewhere in your home.
This prevents the familiar feeling of a sudden blast of hot water whenever someone flushes the toilet. Some models also feature limiters to ensure the water flow can’t become uncomfortably or dangerously hot (8).
This valve type is ideal for homes with multiple residents. It should keep your shower consistent, whatever the other members of your household are doing.
Pros
- Ideal for homes with inconsistent water pressure
- Helpful for large households
- Can be equipped with limiters to prevent scalding
- Maintains a consistent flow rate
Cons
- Designed to regulate pressure, not temperature
Diverter Valves
Diverter valves are designed for bathtub-shower combinations and multiple shower heads. They determine which outlet or outlets the water is allowed to flow from.
If you have more than one shower head, such as a rainfall head and a handheld, a diverter valve is essential to prevent water waste and maintain sufficient pressure. Diverter valves can be either pressure balancing or thermostatic.
Pros
- Necessary for multi-attachment showers and shower-baths
- Choice of pressure-balancing or thermostatic
- Usually less expensive than other types
Cons
- Some multi-attachment models will reduce water pressure
Shut-Off or Stop Valves
Shut-off valves or stop valves allow you to immediately stop the water flow by pressing a button or flicking a switch. They can be very helpful if you are trying to reduce water waste, as you can temporarily pause your shower without needing to turn it off entirely.
This is also helpful if you have a small shower enclosure and usually need to turn off your shower if you want to apply shampoo or other products without accidentally rinsing them off.
Pros
- Eco-friendly
- Simple to use
- Ideal for hard-to-adjust showers
- Inexpensive
Cons
- Doesn’t regulate temperature or pressure
What to Look for in a Shower Valve
Before you start shopping for a shower valve, there are some important things to keep in mind, whatever type you choose.
Size
Ensure your chosen shower valve will fit into your shower enclosure and that it is an appropriate size for your bathroom. You can compare its measurements to your current model to get a better sense of its relative size.
Connection
For straightforward installation, make sure the shower valve will connect to your existing plumbing. Most modern plumbing appliances use standard connectors, so this shouldn’t be an issue but it is important to check.
Type
Consider your specific needs when choosing your shower head type. If you want consistent water temperature, choose a thermostatic shower valve. For the most precise control, a digital shower valve will be ideal.
Manufacturer
Some shower valves require shower heads from the same manufacturer, especially advanced models such as digital valves. If you want to replace your shower valve while keeping the rest of your setup, consider choosing the same manufacturer as your existing unit.
Material
Choosing the right material can be the difference between a shower valve that lasts a couple of years and one that lasts several. Brass, stainless steel, aluminum, copper, and bronze are all reliable metals (9).
Installation
If you intend to install the shower valve yourself, try to choose a model with relatively easy installation. Valves with concealed parts are usually more complicated as you will need to cut into your wall.
Warranty
Shower valves need to be durable enough to cope with constant water pressure. A long warranty is usually a reflection of a shower’s durability, and you will be protected if anything does go wrong with it.
FAQs
Can a Shower Valve Cause Low Water Pressure?
Showers with a single control have a volume valve determining how much pressure is applied. Because of its complexity, this component can, with time, have an effect on the water flow through your shower. In many cases, replacing it is the only choice for repairing it.
Suppose you are having issues with a shower that has a single control. So, it’s recommended you call an experienced plumber to determine whether or not this replacement is required.
How Often Should Shower Valves Be Replaced?
A shower valve will need to be replaced once every four or five years, even if you live somewhere with hard water.
How Much Does It Cost to Replace a Shower Valve?
According to Upgraded Home, the expenses for installing a shower valve can range anywhere from $375 to $575 on average.
Suppose you want to know the hourly rates in your region. In that case, acquiring estimates from many different plumbers is a good idea. That way, you’ll know what kind of expenses to anticipate.
It’s feasible to complete the task on your own. But, if you don’t have a considerable amount of experience, it is highly recommended that you hire a plumber.
Can You Replace a Shower Valve Without Removing Tiles?
You can replace a shower valve without removing the tiles only if there is another way to access the wall behind those tiles. When the plumber arrives, they will inspect the issue and decide the optimum entrance point for replacing or repairing the shower valve.
Although the plumber will take caution to cut or remove only the necessary tile, you may still have to do minor tile restoration work if the opening is particularly large.
The plumber may install an oversized escutcheon to hide the enlarged hole in the tiled wall, a solution that works for most tile restorations.
Do I Have to Replace the Valve When Replacing My Shower Faucet?
If your shower faucet is leaking, your bathroom needs updating, there are mineral deposits, or you just want to update the look, you should consider replacing the valves simultaneously. In addition to driving up water bills, a leaking valve can cause the surrounding wall to deteriorate.
Are Moen and Delta Shower Valves Interchangeable?
Moen and Delta shower valves are not interchangeable because they use different types of fittings.
The cartridge mechanism also distinguishes Delta shower valves from the Moen ball system. Because of this, you can’t just switch out one type of valve for the other without risking harm to the pipes or the valve itself.
If your shower valve is broken and you have a Moen or a Delta model, it’s best to replace it with the same brand and model to keep your plumbing working smoothly.
