Tips on Buying a Shower Valve

Shower Trim vs. Shower Valve 

A lot of homeowners assume that the visible part of their shower controls everything. The shower trim is the external parts of your shower, like the handles and escutcheon plate. However, the shower valve is actually hidden inside the wall, and it has a very important function. Some people assume they can swap out trim pieces and don’t consider the valve at all. Some trims are designed to work with multiple valve models, but they aren’t all universally compatible. If you’re replacing the trim, you’ll need to check whether your current valve will support it. Otherwise, you’ll need to replace both components.

What Does a Shower Valve Do?

Your shower valve regulates the mix of cold or hot water and determines the pressure. Knowing what type of valve you have will make it easier to purchase the right items. There are a few varieties available:

• Pressure-Balancing Valves: These keep the temperature stable by adjusting the ratio of hot and cold water when there’s a change in pressure. It prevents scalding or freezing when someone flushes the toilet or uses the sink.
•  Thermostatic Valves: These allow you to set the water temperature, so it remains constant even if other water sources are used. They offer better control and are preferred in homes with multiple people using water all at once.
• Diverter Valves: These direct the water from the tub spout to the showerhead, or between several shower outlets.

Shower Trim and Valve Compatibility 

A common mistake is assuming that all shower trims are interchangeable. They aren’t. Manufacturers design trims to fit specific valve models, and different brands will have unique connection styles. If you try to install a trim kit that isn’t meant for your valve, it won’t fit. Before you buy shower trim, check the brand and model of your valve. If you don’t know what that is, then the trim plate may need to be removed so you can look at the valve body. Some manufacturers print identifying information on the valve itself, and others have unique markings that match certain trim designs. If you’re installing a new valve, then you’ll need to make sure you choose a compatible trim kit from the same manufacturer.

Do Brands Matter? 

Yes, brand is very important when selecting a shower valve. Major local plumbing companies design their valves with proprietary specifications, so one trim and valve might not work with another’s. Sticking with a reputable brand will make sure that all replacement parts will be available in the future. Some of the most reliable shower valve manufacturers include Kohler, Grohe, Delta, and Moen. If you already have a valve installed and want to upgrade the trim only, it’s best to stick with the same brand so that everything is compatible.

Choosing the Right Finish 

While functionality is the top priority, the finish of your shower trim will affect the look of your bathroom. Shower valves and trims come in a variety of finishes, like:

• Chrome: A popular choice thanks to its price and easy maintenance.
• Brushed Nickel: Gives a softer, modern look that resists fingerprints and water spots.
• Matte Black: Perfect for a contemporary look that makes a bold statement.
• Oil-Rubbed Bronze: Great for traditional or rustic aesthetics.

When choosing the right finish, consider whether it will match your other bathroom fixtures. Making everything cohesive will prevent mismatched metals from clashing.

How Many Handles Do You Need? 

Shower valves come in single-handle and dual-handle options. Here’s how each style can benefit you:

• Single-Handle Valves: These control the water flow and temperature with one lever, so they’re easier to use and install. They work best for minimalist bathrooms and households with elderly individuals or young children who need simple controls.
• Dual-Handle Valves: These will provide separate controls for hot and cold water, and provide more precise temperature adjustments. They also take up a little more space and require a larger installation area.
