What Size Pex Drop Ear Do I Use For Shower Installation?

The size of the pex drop ear usually depends on the fixtures you purchase for shower installation. 

Fixtures such as rain Head or hand held in your shower build have particular fitting.

The fitting is used to attach the shower head hose to the wall. This fitting thread onto a pipe that needs to be fixed below the tile surface by 1/4th to 3/4th inches. 

In order to install body sprays, the pipe nipple must protrude 1/2 to 5/8 inch beyond the tile’s surface (then an escutcheon plate covers the opening). 

The rain head threads into the (female thread) drop-elli which should be below or even with the tile’s surface.

That’s the reason size depends on fixtures, but it is best to use 100% silicone sealer around the hole, after that you can put escutcheon plate cover on.

Generally, the wider the tubing should be, the farther the manifold is from the fixture. That’s the reason 3/4 lines are okay for 250 lengths. 

1 2 pex is fine enough for shower if you require 4.5 gpm (gallons per minute), and your pipe is less than 93 feets. 

Now, depending on your requirements and restrictions, 1 2 pex size can be okay for shower.
