How to remove broken bath tub stopper?

Good luck. I have never seen a bathtub drain like that. My bathtub drain stopper is solid and moves up and down with the switch. Check with a plumbing supply store.

If it's still connected to the actuator handle it's probably just jammed. Spray some WD40 liberally down where the handle screws to. Let it soak for a while. If it's not connected you will need a coat hanger wire and fish for it down the opening. Hopefully you will hook on to it.

Do you know the manufacturer of your tub's draining assembly? They may have a on-line contact ( phone number or email address) or an FAQ section.

Does your tub area have an accessible area behind the faucet/ tap wall for plumbing? If your house is old, this maybe a "picture framed piece of board about 1' wide x 2' high" on that opposite wall or in a linen closet.

If you do, those parts maybe accessible from there and give you a better way to repair it, and if there are additionnal parts you didn't know about.

I hope that helps!

Good luck!

I have to change my stopper assembly and yours looks just like the one I have, Including the perforated drain cover. Go to Home Depot I have seen them there. Bring your old one with you so that they can help you. I am pretty sure they can order one to match yours. My problem is one of the screws that holds the stopper cap onto the wall of the tub broke off because it was so rusted and I am trying to get the part left in the screw hole out.

Remove the 2 screws on the overflow cover plate for the lever and set aside. Then, you'll want to send something down there to hook the plunger attachment and pull it back up. Read about how others fished it out:

Firstly,check for an access panel on the opposite side of the wall from where your taps and drain are located. If there is an access to the plumbing, you may have to drill out the screws in the cover. You may have to replace the whole assembly. Get a price from a plumbing shop. It may not be worth the headache to do it yourself if you don't have the tools.
