Renovation of 3 bathrooms and kitchen floor. On the first day of the renovation, I used a hammer and chisel to attempt to remove the tiles and concrete backing. The next day, I rented a $100-a-day, 22-pound demo hammer that ripped through the tiles and my body. Weighing around 15 pounds with the tile chisel attached, this is the perfect tool for the DIYer or professional. This is a very high quality tool that has already paid for itself in reduced demo time and costs.
