Bathroom and Kitchen Sinks
You can probably buy a new porcelain bathroom or kitchen sink for less than the cost of refinishing, so if your bathroom or kitchen sink is a "drop-in" sink (meaning it can be lifted out from the top to remove), we recommend replacement instead of refinishing. However, if your bathroom or kitchen sink is set in tile or granite, it will be more cost-effective to have it refinished than replaced (since replacement will mean tearing up the countertop).
Please note that our warranty is specifically related to the two things under our control: workmanship and product defects. We do not guarantee that rust, cracks, or holes won't reappear later in a sink if the underlying source of the damage (possibly a house shift, improper initial installation, water leak, or previous damage to the same area) has not been corrected.
