If you're looking to install body jets in your shower, you might be wondering how many you need. The answer depends on a few factors, including the size of your shower and how much coverage you want.
Generally speaking, most showers will have four body jets installed - two on each side. This provides good coverage for the average sized shower. If you have a larger shower, or if you want more coverage, you can always add more body jets. Just keep in mind that each additional jet will require its own water line, so installation can get more complex (and expensive) the more jets you add.
Ultimately, it's up to you to decide how many body jets you need for your shower. Just make sure to consider all of the factors involved before making a final decision.
