My former contractor (who I fired)built me a new bathroom with tub, shower, toilet and double sinks.To feed water to all of these fixtures, he used a half inch pex tube which he tapped into the cold water line from the kitchen sink as a source. Obviously a cobb job. My new contractor wants to run a 3/4 inch line from our main water line into the bathroom. However, this will be very expensive because everything is closed up. My question is this: Can we use the exsisting 1/2 inch line and simply disconnect it from the kitchen sink and connect it to our main water supply? Would that create enough pressure for a full bath?

If you are going to stay with 1/2", just leave it connected the way it is. It won't make any difference.

if you can get to the water lines from below, you can run each cold back to a manifold at the water main and each hot back to a manifold at the water heater.

Even with a 1/2" pipe you should have plenty of pressure to run a fixture in the new bath. If not you have other problems also.
