Shower Valve Type
First of all, it is essential to determine what type of bath valve you need, as different types can be found. Some of these include, in general, the:
Diverter Valve: The divert valve is a good type to choose if you already have a bath that has a faucet but you wish to have a soothing bath rather than a shower. The shower valve sends water toward your shower head because it sends it from the faucet.
Pressure Balancing Valves: These valves ensure that your water circulating load remains constant without fluctuating both from full stream of water and then to a gradual stream or the other way round.

Thermostatic Shower Valves: These valves prevent the temperature of the water from changing while you shower, even if someone is operating different faucets in the same house.

Number and Size of Outlets
Shower valves usually come with 1, 2, or even 3 outlets. Meanwhile, with models which have a shower valve with one outlet, you can operate an overhead shower. Meanwhile, a valve with two outlets can make it possible to add a side rail. And with a valve with three outlets, you can have an overhead shower, body jets, and a shower with a slide rail.

Before selecting your bath valve, make sure it uses high-quality materials. The product must also have a stable development to last you for an extended time. The most used materials are welded metal, copper, and brass. Models with cheap plastics should be avoided. Whatever your selection, make sure the valve is protected from corrosion and heat. A chrome polish can offer aesthetics and function against corrosion.
Not all shower valves are universally designed so you have to ensure you’re choosing a valve compatible with your plumbing outlet. You can’t mix manufacturers when it comes to rough-in and trim valves. Hence, the trims cannot be interchanged. While the best shower valve to choose is that with a universal trim, many brands don’t ensure this. Some can only be used to replace their type of valve. However, some models are compatible with a single and double thermostatic cartridge.
Trim is used to referring to the visible and decorative part of the shower or combo faucet set. It can include your tub spout, showerhead, handle and control. Some bath valves include handles, trims, and various accessories. In case you opt to choose valves that have a chord, check if the chord is easy to use.
Warranty coverage is important as these items can be expensive. Some models in packs come in several hundreds of dollars, but there is no way to assure users of the product quality except by offering warranty coverage. The warranty coverage for this type of product can span 1 to 10 years. A lot of models come with a lifetime warranty, however.

How to Install a Shower Valve
Before you start the installation, ensure that all the valve openings are covered to avoid debris from getting inside while you’re working on the supply lines.

Water pipes with cold and hot water must be fixed in the panel or wall to avoid movements after installation and to support your valve.
The installation is easier as explained. In other words, all you need to do is remove the existing shower valve that requires replacement. Then, disassemble the new valve.
