bathroom from hell

[Brian K.]

so I hired contractor  to remodel bathroom and he contracted it out to another contractor  who's cotracts bad contractors to to work.I had to have them gut the bathroom again  and do it again.it still wasn't done properly due to they put up drywall and they didn't even prime walls  so paint comes off,the tile is 2 diffrent colors when supposed to be all white,the drain pipe is not to code and looks like cap so I had to fire them.now he wants to be paid in full and said if don't will put lien on house .I don't feel that they completed the job correctly. there wasn't sign contract with this contractor .I would be willing to pay for one set of materials  but nothing  more since I have to find another  contractor  to do it correct .what are my options ?
