Bathroom receptacles.

I have an addition being added on to an existing residence.

There are 4 bathroom vanities each having a sink and small make up area . 8 receptacles total.

The space is in conjunction with 4 new bedrooms each being for children currently aged 9-14.

Would it be wise to dedicate a circuit to each bathroom space?

Area is second floor and wil be inaccessible once it’s finished.

Seems overkill to pull 4 home runs but then all 4 girls using blow dryers and other hair accessories at the same time seems likely.

Home runs are long, opposite end of house and not an easy path .

Thoughts?
 
I would try and talk them into dedicated for all.
If they don’t bit o well.
If your bidding just suggest what you want after you quote them the least costly option.
If it was my house I would run to each just cause it make me feel good lol

Plus do what Bill said will save you time and headaches down the road

I would give each sink/make-up area a circuit, meaning four circuits.

One girl isn't likely to use both areas at the same time.

I would use standard 12-2 instead of 12-2-2 for better heat dissipation.

Better yet, pull larger wire and add a subpanel. That would give you shorter HR and a place for anything in the future.

No physical location for a sub panel. That was my first thought.Only place code compliant would be in the hallway and owner said no to that. There are clothes closets but code prohibits that.
 
Use 210.11(C)(3) to indicate each bath be on its own circuit and allows for the bathroom lights and fan to be included with it in each single bathroom. Even connecting 2 of the baths would be pushing it with blow dryers operating simultaneously, typical blow dryer is between 1200 to 1875 watts.
 
You could also pull 8/2-g to each receptacle,
if overkill is what you're going after 🙄

For real, tho - outside the Master Bath being on its own, I put receptacles for 2 bathrooms on one circuit.

If you want a realistic idea of how often those bathrooms will all be used at the same time, ask how much hot water capacity they're gearing up for.
hen introduce the idea of a separate circuit if need be.

And I sure wouldn't be pulling any 12/2/2 because the cost is more than the price of two separate 12/2. Then you have extra time with jumpers and extra makeup in the boxes.

Extra conductor fill in the boxes as well.

Yeah I was thinking about that. What would that first box look like? If you have a circuit out on the black plus white and another circuit out on the red plus white? What kind of a box and how much extra labor?

Too much fill for a 22 cubic inch box. Not necessarily easy to find a one gang non metallic box larger than that, probably needing a 4x4 and mud ring if you only want a 1 gang opening. Not that it isn't do-able, but between that and price of 12-2-2, probably less cost to make 2 runs of 12-2. Labor somewhat insignificant for short run. Long run? you possibly have lot of cable to run and possibly can pull off two reels at same time and labor is sort of negligible for that method as well.

I also don't see the attraction to 12-2-2 and 14-2-2, except perhaps for combination loads like bath fan/light/nightlight/heater/etc.

Cost - value not there compared to 2 individual runs but I will use for difficult pulls on existing structures where getting one pull for 2 circuits makes life easier. For the combination load referenced would use a 1#/4, it gives me the 3 loads compared to only 2 with the 1#/2/2, and it's cheaper than 1#/2/2.

I still use multiple runs of 2 or 3 conductor cable for those. bath fan units are what, 10 to 15 feet run to the switch box in most cases? No savings whatsoever here by using 12-2-2 or 14-2-2.

Only had one that had heat as well as light and exhaust that did need one extra control line separate from each part, it needed 12/4 MC per mfg. specs., not NM.
