How to drain basin into tub

I put a floor-standing plastic basin in the bathroom so I can temporarily do laundry by hand and avoid my building's laundry room. I'll fill it with the showerhead. After the wash I want to pull the stopper and have the water drain into the bathtub which is 6" away.

The inner diameter of the drain is 1-1/2". That's also the size the manual says the drain is. The outer diameter is more like 1-3/4" which I guess doesn't matter in plumbing...IDK...it made me uncertain when I was looking at rubber couplers.

A flexible hose that would screw into the plastic drain would be good. Or an elbow plus a straight section. I found an elbow called "1-1/2" Socket x FNPT PVC 90 Degree Elbow Sched 40" (the manufacturer calls the same model "Sch40 90 Elbow Slip x FTP"). I'd have to get another piece to slip into the non-threaded end and I wasn't sure what to get.

I think it could be done for $20??? I want to order online. Any suggestions on what to order?

I would have simply done the wash in the tub.

Unless you're in a hurry , I'd plug the large drain hole and use a section of garden hose or aquarium tubing to siphon the water out and into the tub.

I think what you want to do could be done with a short 1 1/2" sink tail piece and an 1 1/2" slip joint trap kit... Plus maybe a 12" extension tube.

Your basket is probably like any standard threaded sink basket... But you may need the hat gasket and slip joint nut for the top of the sink tailpiece since those usually come with the basket.

You could also do it easily with PVC fittings and glue. A female hub and a couple street elbows.

I even have a siphon and I saw an old photo of a woman using a washboard in a bathtub so I guess it wouldn't have been that crazy but at least now I don't have to be on my knees.

I looked at a trap kit. I think a tailpiece and a waste arm is all I need. I found a video on how to connect them. I think I'm all set!
