Is there bathrooms and showers.

I dont remember a shower but there is a pretty private restroom, just bring a flashlight or a lantern because there is no light in there at night (at least none that I saw)

Like large port a potty but very nice and clean. No showers there,showers at lower camps

At Wash Burn there are bathrooms but like right next to it is San Simeon camp ground there are showers there and better bathrooms .

Bathrooms yes, showers are below at San simeon.
