Preferred minimum pressure at furthest fixture

[Rossn]

Are there any rules of thumb about the preferred minimum pressure at the furthest fixture (in my case, a 3/4" bathroom)? Standard flush tank toilets. I believe the 2015 IPC calls for 20psi for thermostatic mixing valve showers, etc, but that cannot be a great experience.

What's the preferred minimum pressure?

The middle chart I use is 40/60 PSI

Perfect, and thanks so much. Sounds like 40-45psi at the furthest fixture should be acceptable.

Funny think is IPC 2015 shows 30-39, 40-49, and 60+. I think they have a typo.
