Older house plumbing drain question

Hello all new to the forums.

New house (first house) being remolded before move in so ill have a few questions on things....so thank you ahead of time!

Anyways first thing. What would have to be done to properly drain the sink if you can tell be the pictures. The drain it was attached to is the the left of the toilet It is 4" at the opening and about 2" down it tapers to 2"

The basement bathroom was a mess so the walls were torn down and the sink was removed as the plumbing was just a hack job to say the least. The sink was hooked up through a pipe that was lead into what looked like a parking block (seriously). After removing the 2 foot piece of cement it had appeared they had just cemented the pipe above ground to an existing floor drain.

What Mike said about the drain. To install it properly, it will also need a 1.5" vent going up and out to the roof. You can't tie the vent into the stack right there since there are other fixtures above draining into it and it would create what's called a wet vent.

I'm not convinced that the toilet is vented properly either... but maybe it's grandfathered in since it was likely plumbed when the house was built and before fixture venting was required. You may end up with gurgling and a smelly toilet occasionally.

Depending on what you have planned for this bathroom, you may want to consider replumbing all the drains and vents for it and doing it right.

Zorfdt thank you. This does answer a lot of my questions. So another vent stack would have to be run The long 1.5" pipe coming in is the tub from upstairs and the larger pipe is the bathroom sink. The kitchen is run to a different stack about 20 feet away.

That looks like a floor drain. Are you saying the sink drained to there?

Yes, that is exactly where the sink was drained (a small bathroom vanity). We pulled out the sink and that is what was there.

If that is incorrect as a sink drain, may it be safe to assume the toilet is improper as well?

Yes you can assume that. Most likly there is no vent . you would need to jack hammer and re-pipe some to make code compliant.
