I am currently building a new home which has 2 1/2 bathrooms and I need help with the wiring. There seems to be some differing opinions on the best approach. I don't know whether I should wire receptacles from multiple bathrooms on one circuit, or dedicate one circuit for an individual bathroom and include the lights/fan. Is one method better than the other? What should determine which option to choose?

Re: Bathroom Circuits

For a better job, I like to run a 20amp to each bathroom..All bases seem to be covered that way (for now and future). You wont have to worry about 2 hairdryers running at the same time (15amp each) and all the other little accesories that are out there. Of course, watch the total load with the lighting.
 
Re: Bathroom Circuits

The master bath will have a light in the walk-in closet, one over the shower, one in the separated toilet area, one in the center of the bathroom, and vanity lights. Sound OK? Thanks for your help.

Are you wiring the home yourself?

Are you asking about how to design the system for some one else to install?

It would all come down to what YOU want to have installed. Either way you have mentioned would be code compliant.

Considering the amount of lighting (you didn't mention an exhaust fan) I would use two circuits. Run a 12/3 instead of a 12/2 and split the lighting and power. Many building codes will require an exhaust fan if a separate toilet room is built without a window. I would put that on the circuit with the lighting. Also if another bathroom is in close proximity you could feed the lighting in that one too from the same circuit depending on your total lighting load.
 
Re: Bathroom Circuits

Personally i prefer dedicated circuit per bath room.From labor standpoint i think its faster.That way bathroom can be finished fast taking care of receptacles and lights.Running 12-3 would also be great idea as you could get hall lights,livingroom ,etc from the extra circuit.Just not bedrooms.I would give thought to the wattage of the lights.And have had bathrooms that needed 3 circuits

For those that use the dedicated circuit idea,do you think it's a good or bad idea to protect the lights on the load side of gfci ? I know not required by nec.Doing it adds safety from shock but at same time puts us at risk of being in the dark and in a tub or shower.

Re: Bathroom Circuits

I would put m. bath receptacles and shower light on load side, one circuit. 2nd and 1/2 bath recpticals one circuit with gfi in 2nd bath. the 1/2 bath receptacle will not be used much outside of a night light. and the lights and fans on with other gp lighting circuits. 14-2 is easier to work with on lights. and less likely to over fill boxes.

This appears to be a DIY thread, and as such not permitted by the forum rules, so I am closing it. Normally I would contact the original posted by PM, but he has chosen to disable that function.
