Shower pressure difference (Identical Showers)

[Teknet]

Hi guys…

I have a megaflo unvented cylinder so I am on mains pressure which is pretty good. I’ve got 2 showers upstairs which are both new and both have identical Grohe shower bar sets with new heads and hoses etc.

I have noticed that one of the showers has really vigorous pressure when you open it fully, however the other one is about 20% less.

Is there a reason why this might be? I don’t know if this makes a difference but the better shower is a lot closer to the megaflo cylinder than the other one?

Thanks

Which one if any is most used

Both the same tbh

Depending on available dynamic pressure, the length of the run and number of bends then one shower could flow less than another.
