A shower valve is a device that regulates the flow, temperature, and supply of water to the shower head. It functions similarly to the water basin’s faucet.
Shower valves come in various sizes ranging from 1/2 to 2 inches, each with its own set of advantages and disadvantages. The most popular sizes are 1/2-inch and 3/4-inch valves, which in most situations offer adequate performance.
In this post, we’ll compare both shower valves, their differences, and their advantages and disadvantages.
Differences Between 3/4 And 1/2 Shower Valves
The primary difference between a 3/4-inch and a 1/2-inch shower valve is the amount of water supplied and the rate at which it is supplied. A 3/4-inch shower valve will deliver more gallons of water per minute (GPM) than a 1/2-inch valve. Other differences between the two are as follows:
Similarities of 3/4 and 1/2 inch Shower Valves
The 3/4 and 1/2 shower valves share some similar characteristics. Both allow for controlled water flow to the shower head. Both valve types can have one, two, or three outlets and can be made of PEX or copper tubing.
Advantages and Disadvantages of 3/4″ and 1/2″ Shower Valves
|1/2 inch||The main advantage of a 1/2-inch shower valve over a 3/4-inch shower valve is that the smaller orifice allows it to fit better in bathroom fittings, especially if there are many outlets.||1/2-inch shower valves are more expensive.|
|It is more resistant to high water pressure than 3/4-inch shower valves.|
|3/4 inch||A 3/4-inch shower valve retains more water.||They can’t handle as much water pressure as the 1/2-inch shower valves|
|It is generally cheaper than a 1/2-inch shower valve.||The water supply can be too much, especially in homes where the valve serves just one outlet.|
Which is the best option for your bathroom (3/4 or 1/2 inch)?
There are several factors to consider when selecting a shower valve. The first consideration is the size of the shower. The most common shower valves are 1/2-inch in size, but 3/4-inch valves are also available. The water pressure comes next. Most homes in the United States have water pressure ranging from 40 to 80 psi. 1/2-inch valves perform better with high-pressure water. Finally, consider your bathroom’s design. A 3/4-inch valve will look better in a modern or contemporary bathroom.
How to know what size shower valve you need?
Your bathroom fittings will heavily influence your choice of a shower valve for your bathroom. Most shower and tub faucets use 1/2-inch supply pipes. Ideally, it would be best to look for a 1/2-inch valve to go with it. The same should apply to a 3/4-inch arrangement. The pipe material will also determine the size of the valve to purchase. For example, a 1/2″ PEX pipe is not the same as a 1/2″ copper pipe; PEX is smaller and more commonly used.
