I am adding a bathroom in our basement and all is going fine, but...I am wondering how big a supply line is needed. We currently have a 1 inch supply coming into the house, and it splits into 3/4 inch to the hot water heater and 3/4 inch to the rest of the house. The new bathroom supply will go to a toilet, sink and shower as well as a pre-existing hose bib on the outside. Will splitting another 3/4 inch line from the 1 inch house supply to the bathroom be too much? Do I dare just use the 1/2 line that currently goes to the hose bibb? What do you all suggest?

How many fixtures do you plan on using at the same time?

What is the available pressure.

If one is going to shower and water the garden and use the dishwasher and someone decides to take a bath you may have a problem with pressure drop.
