We recently replaced our toilet suite and ran into a problem with the floor tile. I thought the new toilet would cover the old tiles, but we ended up with gaps between the tiles, and it was so ugly. I got a couple of quotes from tilers, and it was going to cost 300-450 dollars to replace. I decided to have a go at it myself, and it turned out pretty good. It looks neat and tidy now, and it only cost me 20-30 dollars to do. The first part is to remove the old tiles around the base. Once that is done, you will need the following to repair the area.
1) Mark the tiles; watch this youtube video

2) Securely fix the tile onto a support (i.e. concrete paver). I also had a piece of cloth underneath the tile to absorb the vibrations to prevent the tile from cracking.
3) Use the Grinder and slowly cut through the tile following the markings. Fit the tile into position and, if needed, trim around the edges for a neat fit and finish. When you are happy with the fit, add adhesive, wait to set overnight and grout the next day.
What an outstanding job you've done there @Nham!
