Bathroom fixtures: How many can be supplied by 3/4" PEX

[PrecisionPlum]

Situation: Failed copper feed for two bathrooms back to back
The least intrusive repair is to thread 3/4" PEX down to the basement
Supply pressure is a solid 50psi

Question: Will one 3/4" PEX adequately supply two bathroom groups?

Note: The concern is about pressure changes when both bathrooms are in use.
I.e. Shower in use & WC flush.

Thank you for your response.

How high above the meter is this bathroom?

Technically no, but it’s done everyday.

How high above the meter is this bathroom?

Approximately 18'. The meter is in the basement, and it is a second floor bathroom.
Add another 6' or so if you want to get to the top of the shower head.

3/4" won't quite do it. In order to say for sure there are more specifics that need to be cleared up, but most likley not. Use 1"
