Only a few walk-in tub brands don’t offer a warranty. However, the coverage level of warranties differs greatly from brand to brand, even when the warranties are advertised with similar language. The most common form of limitation for warranties is time. Many warranties expire after five or ten years. Some warranties cover every single piece of the tub, but most cover only specific components and exclude things like the tub’s finish or the motor. Since there’s so much variation in warranties, it’s best to read the fine print on the warranty page.
