Your Fiberglass and Tub Experts

Bontrager Fiberglass Specialties Inc. has been one of the country's foremost fiberglass repair specialists since 1984. We do most of our boat repairs in our Southwest Michigan facility but can also travel to fix bathtubs and showers. 

We are located in one of the largest boating regions in the U.S., which always keeps us busy in our shop repairing worn and damaged hulls, transoms, decks, and more. Our reputation for quality craftsmanship has taken us all over the U.S. and the Caribbean to do hotel bathtub and shower repairs. We provide warranty work for most major tub manufacturers.
