Adding a Third Bathroom

I'm planning to add a third bathroom to the 2nd floor of my house. Currently the main branch supplying the house is 3/4". The line coming into the house before the meter is 3/4". If I'm reading the pipe size charts correctly, it appears that the branch after the meter should be 1". Is this correct? I came up with 32.5 fixture units for the entire house including the fixtures for the new bathroom.

1 Bar Sink
1 Bath/Shower
1 Clothes Washer
1 Dishwasher
2 Hose Bibs
1 Kitchen Sink
1 Laundry Sink
3 Bathroom Sinks
2 Showers
3 Toilets

Thanks!

3/4" wouldn't meet code here. A very good chance 1" is fine. But, we need to know the pipe distance, static water pressure, along with any significant elevation change.

The 1" after the meter sounds about right if you are within 80 feet and normal pressure.

Does what I have now meet code? Take away 1 sink, 1 shower, and 1 toilet from my original post.

I'm wondering if I can get away with branching from the meter rather than replacing the existing 3/4 line. The run to the furthest new fixture would probably be about 60-70 feet.

Three bathrooms will still require a 1" line on the cold side.
You can also add more 1/2 and 3/4" lines to the mix.

So will this work?

I'm back again. I put this on hold for while, but now I'm ready to get back into it.

Will this fly?

-Change supply line to 1" at the meter.
-Keep the existing 3/4" cold line in place, but now branching off the new 1" line.
-Keep the existing 3/4" hot line running to water heater and to existing fixtures in place, but branch off the new 1" line.
-Branch off the 1 inch line with new 3/4" for cold line to new bathroom
-Branch off the 3/4" hot line with new 3/4" after the water heater for the hot line to the new bathroom.

So… let's recap.

1" from meter
3/4" cold branch to existing run
3/4" cold branch to new bathroom
3/4" hot branch to water heater
3/4" hot branch after water heater to existing run
3/4" hot branch after water heater to new bathroom

Does this make sense - I've attached a drawing...

Looks good to me.
