Tie into existing drain?

I am installing a shower in a bathroom upstairs. I plan on running a P-trap underneath the shower, and then running the drain down to the basement. Here, I want to tie the shower drain into the drain for either the washing machine or the kitchen sink. Can I do this?

Plan

My plan was to run the new shower drain down the wall and then slope it down over to the sink drain. The sink drain is 2" ABS. It runs along the basement wall, turns a corner, and then runs into the sewer going out of the house. If I can't do this, do you have other ideas?

As long as you tie the shower drain into the 2" kitchen drain downstream of the kitchen connection and do not disrupt the went for the kitchen, you will be ok to tie into that drain.

The shower drain must be 2" with an 1 1-2" vent tied into the venting system above the flood level rim of the shower.
