I am installing a bathroom in my basement which include a sewage waste pump. The pump is 1/2 horse and rated at 19.4 amps normal running. Would it be too much if I was to hook the sewage pump, a gfci outlet (for shaver or hair dryer) two lights fixtures and an exhaust fan to 1 20amp breaker? The most that would be running at one time would be the two lights, exhaust fan and the sump while taking a shower.

I had put that the sewage pump normal operating amp are 19.4 and it should have said 9.4

Yes, a single 20A circuit should be able to support all those loads.

But you need to check with your local code -- somethings things like bathroom pumps are required to be on a circuit of their own.

You might consider running a #14-3 cable to the bathroom, from 2 15A breakers, and having 2 separate circuits in the bathroom. That gives you some leeway for any future additions.

The bathroom needs to have a 20 amp circuit for the receptacle.

And if this is the only bathroom that circuit feeds then lights and fan can also be on it.

But you could do what Tim suggest (a multiwire circuit) with #12 (20 amp).

As I read the code, since the pump draws less than 50% of the circuit rating and it is installed in a bathroom then it can be on the bathroom circuit.

But local codes might have amended this.
