Step 1: Do the math and get supplies.
-Tile Roller (rental costs ~$15/day)
-Mini Prybar (not pictured)
-Basic hand tools (pliers, adjustable wrench, screwdrivers, etc....)
Speaking of math, the tile is $30.60 for 45 tiles, and adhesive is about $20/gallon. For my room of 256 square feet, this added up to about $250, so that's one thing to consider. On the other hand, this is the most durable flooring you can possibly buy, unless you've had epoxy painted concrete or ceramic tile, which is way harder to lay and way more expensive. Someone told me they had this stuff last them 50 years, and it's still in perfect shape!
