AAV venting for new basement bath?

[nocodyi79]

Planning on a bathroom with a freestanding tub, in front of a shower enclosure. Double sink adjacent and next to it the WC.

1. The basement has a rough in vent, but about 20 foot away in other portion of basement.
2. Directly above planned bath is upstairs bath. I do see the trap for the tub coming through the floor, with a wye. Is that a vent or the tub overflow? If it's the vent, can I use that for the basement bath?
3. Is a double sink considered two fixtures?
4. Can I AAV under the double sink?
5. Can I AAV the shower behind wall, with access and register on other side of wall (storage room)?
6. How to vent the freestanding tub?
7. I will cut up concrete and reroute existing rough-in

questions questions

Many thanks Frodo.

Would need to determine how to connect the drains to the main, and how to vent the freestanding tub and shower and WC. The vanity and wet-bar will have AAV.
