Good luck getting an answer you can use at johnbridge. They'll probably tell you to tear it all out and lay down the ditra mat, etc.
Go buy a bottle of sealer. Pour it liberally down the wall of your shower. Wait a day for it to dry. Hit the area with water. If nothing runs off, you're golden. If it's still streaky, demand the contractor completely remove 100% of the grout and install a grout that won't run. Spend an hour and $5 and have a definite answer.
