Today the tub refuses to drain, even a little
bit. I tried the following and none worked;

1) plunger (while trying to block the overflow
hole)
2) taking the thingy out the switches from shower
to tub mode
3) snaking the drain by hand, both from the drain
and the overflow hole
4) vinegar and baking powder
5) boiling water


None are working! Any other ideas?


Thanks in advance!

Block off the overflow with wet rags stuffed in.

Use a Shop Vac to suction at the drain opening.

Beyond that, you will probably need a professional-size
drain/snake machine.

If there is a trap which can be accessed AND opened,
that may help get a snake in.

Tub drains are often the most difficult to clear.
