Finishing the Unfinished Home Improvement

Hired Eric to finish my 5x7 bathroom. What a mistake!! Initially quoted $3500 to redo the floor and wall tiles, replace the cement board and put in new faucets. I also asked for him to install a toilet after the initial estimate. The bathroom ended up costing over $9000 to redo because he did tasks I did not ask for him to do - eg. changing wall light to ceiling light, ripped out vanity, etc. For $9000, the work he did was poor. He scratched the bathtub requiring me to purchase and install a new one. The tiles are completely uneven and not level with the wall. They are also covered in grout in spots and he installed chipped tiles. The floor tile is missing grout in spots. He somehow put grout on the hallway walls requiring me to sand and repaint those walls as well. Eric made multiple holes in my bathroom walls and just left them for me to fill and fix. The mud for the drywall was not properly applied, smoothed or sanded. I had to remud the walls and sand before I painted them. The vanity was installed with a large gap between the vanity and the wall. It was also not centred on the wall. Eric cut a large hole inside my brand new vanity so I cannot even move the vanity to make it flat against the wall or centre. When requested to fix the problems, he refused. He did offer to put a lien on my house though.
