I've taken a lot of showers over the past couple of weeks. When testing a showerhead system, I look at a lot of factors: The diameter of the face, the gallons-per-minute output, the number of settings, the materials, the design and more. We also run an anecdotal test on the water flow, water pressure and power of the spray pattern with dried egg yolk. More than anything, I showered and noted how each shower experience felt.
I leave each model installed for a couple of days so I can take a variety of showers. During the first shower with a new shower system, I'm paying close attention to each spray pattern and how they feel, but I also want to shower when I'm not thinking about it as much. With each model, I shower when I'm groggy in the morning and do a post-workout shower to cool down.
After every shower, I take notes on the shower experience. Was it firm, relaxing or both? Was the showering experience intense enough to get the soap and shampoo off quickly or did I have to change settings? Is it easy to change settings?
For the egg test, I brushed egg yolk onto a cutting board and let it dry for 24 hours. Then I held the board 20 inches from the showerhead while it ran for 10 seconds and noted how much yolk was removed. I ran this test for each setting on each showerhead. Most only removed a little yolk if any, but a few settings proved weaker or stronger relative to the rest.
Different showers check different boxes, but at the end of the day, what mattered most to me was the actual showering experience. None of the models I tested were terrible, but a few rose above the rest and cleaned up the competition.
