Some walk-in tub companies will offer a lifetime warranty, which means that the company will repair or replace the product during the life of the product. However, many of these companies have restrictions; it is best to call and ask a customer service representative. A limited warranty generally refers to specified parts, certain defects, and other conditions. It could mean that just the parts are covered but not the labor to fix the parts. Again, we suggest you call and ask your walk-in tub company about the limited lifetime warranty before finalizing the purchase.
