Can I add a laundry tub next to my washing machine.

When everything was installed it was supposed to be set up for a laundry tub, but I don't know that it was done correctly.

This is the current set up. Basically it's 2" drains going to the washing machine. I just want to add a plastic laundry tub to the left side of the washing machine. Can switch the single to a double sanitary tee and add the tub, or is this going to be impossible without breaking open concrete?

Or do I have to go all out with something like this?

What should be done?
