Basement bathroom plumbing plan, new version

Thanks for the many helps from here, I put together the newest version:


Pls click to enlarge.
Does this look good? Do I need a cleanout at the 1 1/2" 90 elbow for accessing from back of the wetwall? Or change the 90 elbow to 45?

I ordered the 27x54x16 tub, it was said to be for above floor plumbing. So I thought the P trap can go into wetwall from above the ground.

it will need 3 weeks to arrive. I will breakdown the cement and try to tie the underground part together this weekend.

Breaking the cement is not so easy. It took me whole Saturday to cut the cement with circular saw and then sledgehammer 10' . I am to tired to dig the trench today.
