There a lot of ways remodel old bathroom tiles. Searching the Internet will yield lots of results on this stuff—there are plenty of how-to articles that deal with the specific topic of bathroom remodeling. Remember to be careful though. Not everything you find online comes from trustworthy resources.
The Internet is not your only option, you can pick up books on remodeling in the library or a bookstore but the best way to actually learn about bathroom remodeling is to watch someone do it.
What you must know
You have to know what you have and what you want to replace it with. The safest way we could go about replacing old tiles is to choose the same design as the one you are replacing. While this ensures your new tile will mesh with the bathroom, it is, however, not the most creative way to go about bathroom remodeling. If you want to keep the same kind of style just bring a single tile with you to the hardware store so you can see the different options available in the same style. Taking the creative route, however, is a lot more fun and more rewarding. Don’t limit yourself when it comes to tiling. Remember, different sized tiles will cost differently per square feet.
DIY: not for everyone
While not recommended, it is rewarding if you do it right. Taking charge and taking the time to learn how to do your own bathroom remodeling right can be a satisfying experience. Just be sure that you do indeed do it right otherwise it will cost a lot more in repairs in the future. The safest way to go about it would be to hire an expert and discussing your available options.
Just remember that you can’t use the bathroom immediately right after you finish tiling. You have to give it some time before you can use the bathroom again otherwise you would have wasted all that work
