This corner tub was installed and worked when I purchased this home 5 years ago. I had the faucet going and when I went to turn it off, the faucet wasn't catching properly. Luckily I mostly got it turned off, now it's just a trickle. Even with pliers the stem just spins almost freely.

I thought it was the knobs set screw but it isn't. I called a plumber, he wasn't able to get the thing turned off either and recommended I try to find a specialist.

To me, it doesn't look like there's a way to access the internals of the tub, and I wasn't able to find a service manual.

Any help in identifying this would be appreciated. Hopefully I can figure out a way to open it up and replace the busted valve.
