I am replacing the tub drain (chrome to bronze). I was wondering if I should use plumbers tape on the drain, or is the putty enough?
EDIT: Thank you for your responses. I am changing the drain only. I guess a better question is, should I use plumbers tape between the drain and drain shoe? I know I should use the putty on the edge of the drain but someone told me to use plumbers tape on the threads. I just changed to whole drain shoe and I'm afraid to mess it up by doing it wrong.
Second edit: thanks again for all your responses. It seems the general consensus is that I do not need tape. The shoe is pvc and the drain is bronze.
goes in the pipe, which is probably no more than 1-1/2 to 2 inches. The seal is formed by winding up the screw so that the rubber seal is expanded against the walls of the pipe. I have no idea where you think you can stick a 3-1/2" stopper in the washing machine box you've pictured. You'll need to cut the hole for the drain properly if, as it appears, it's not really matching the hole in the pipe.

You don't need tape for the seal (those drain to shoe threads are not where the water seal takes place in those parts) but since you are using metal drain parts teflon tape or pipe dope does greatly increase the odds that you or the next person will be able to get them apart, rather than finding them irrevocably corroded together. I'd actually prefer pipe dope for the purpose.
As for putty, that apparently depends on the tub material. I was looking up instructions for my new-ish tub and was very surprised to find that silicone caulking was the recommended material for my tub - apparently plumber's putty does not get along with acrylic tubs? I'm going to guess that your all metal drain probably goes with a cast iron tub where plumbers putty is the right material, but I offer that observation because it surprised me, and made my tub of plumber's putty feel sad and unwanted, poor thing.
