When it comes to stained or damaged tile, there are two main options: refinishing and replacement. Both have their pros and cons but ultimately the best option depends on the specific needs and goals of your project.
Refinishing and repairing is often cheaper and faster than replacement, and it can be a good way to update the look of your home without a major overhaul. However, refinished porcelain is not always as durable as a replacement counter or floor, and it may not be an option if your tile is severely damaged.
Replacement is a more expensive and time-consuming job than refinishing services, but it can give you a completely new look with more durability. If your tile, sink or bathtub is severely damaged or you want a completely different look, then replacement with a new floor or new tub is likely a better option than repair.
