Adding laundry tub next to washer

[IanH]

First time posting. I have done quite a bit of Googling, but I would really appreciate expert opinions. The attached pdf shows a pretty accurate scale drawing of what I want to do. Because of the existing setup, in our recently purchased house, the tub has to go to the left of the washer and the washer can't easily be moved. I put a few notes on the drawing to explain what is what.

Thanks in advance for any and all help.

That connection off of the standpipe trap arm is probably already a santee.

The new fitting where you convert from horizontal to vertical will be 2 x 2 x 1.5, which you probably already intended.

I am not a pro, but it looks good otherwise.

Reach 4,

Actually the existing plumbing is as drawn. I will replace the wye+45 with a santee when I do the rest. Thanks for the input.
