Hmmm... Well are you handy? If so then you should be able to do this without the expense of hiring a professional like me. Hopefully, you are dealing with a full tile and not one that has to be cut. If it does have to be cut than hopefully, it is a straight cut and not a fancy cut.
Assuming it is a full tile here is a list of tools you will need:
1. Safety Goggles
2. Leather gloves
3. Grout scraper
5. Wide and narrow chisels (2"-3" chisel, .25"-1" chisel)
6. Shop Vac
7. Square notch trowel
Wear your safety goggles and leather gloves. First, using your grout scraper, scrape the grout out around the tile to be replaced. This will relieve the tension between surrounding tiles. Second, using your large chisel and hammer, chisel out a corner of your tile. Next, chisel out the remaining section of tile. These tile fragments will be razor sharp so do wear gloves and handle with care. Next chisel away the remaining thinset, being careful to not disturb the surrounding tiles. Finally, clean up the dust with your shop vac. Reapply the new tile with thinset, wait 24 hours then grout in. Good luck!
If your tile needs to be cut, you may need to rent a wet saw or straight manual cutter. Now if you have to rent a wet saw anyway, why not just skip the hassle and hire a pro?
