If your subfloor is in good condition then you may be good to go on the installation. But you can’t really always tell. Get a professional opinion on this and also see how much it would cost to get it professionally done versus a self-install.

Install Your Own Tile Flooring
With many purchases, adding on installation to the actual product can cost a lot of money. Especially when the cost of the product is pretty low, installation costs can come close to and even cost more than the actual product. If you have more time than you do money to spend, consider installing your own tile floors. Installing tile flooring can be a difficult task, so check your handyman meter before proceeding with caution.
