20 amp circuit and 15 amp receptacles

I've wired two circuits in my basement. One is for a utility area (cabinets and countertop) the other for a bathroom. Both 20 amp with 12 gauge wire.

For the bathroom (3 junction boxes) I plan to install a 20 amp GFCI but looking to use 15 amp outlets for the other two. My understanding from research is that this is acceptable because there are multiple outlets.

At the countertop area, I bought 2 20 amp receptacles and have a 15 amp duplex outlet with two USB receptacles.

I have no 20 amp devices. My question is, can I install only 15 amp receptacles on this circuit with no 20 amp receptacles at all? It appears ok to mix them but I am not sure if you could have only 15s and no 20s on the circuit.

Thanks!

You can have 15A devices on a 20A circuit as long as there is more than one. A standard duplex receptacle (top and bottom) counts as two. Your plan all sounds ok based on the description.

You only need to use 15 amp devices for all purposes including GFCIs so long as there are two places to plug in. A single duplex receptacle counts as two places.

Thanks everyone. Is there any advantage to installing the 20 amp GFCI in the bathroom instead of a 15 amp GFCI?

The only thing I can think of is if my gf gets one of those hair dryers the princess in Spaceballs had

After doing additional reseach it seems the internals of the 20 are the same as the 15 - just the face is different to allow 20 amp devices.

That is correct. .

No. I have never seen a hair dryer that has a 20 amp configuration plug on it. Nor have I seen a "normal" household kitchen appliance.

Thanks all. There appear to be more options with the 25 amp GFCI so I'll likely go with that.

I heard there are some microwaves with a 20 amp receptacle but not relevant to my situation.

Never seen one of those.

Never heard or seen any of those either. Except for commercial equipment, most appliances will have a 15 amp plug.

I don't believe I have ever seen a case where a residence needed a 20 amp 120 volt receptacle even when I consider some pretty big power tools and air compressors. There is definitely no good reason to install a 20 amp GFCI receptacle in a bathroom or kitchen.

I've got a compressor and some heavy duty power tools (ie Milwaukee SuperHawg) and they all use 15 amp plugs.
