I just found a small crack, about 1 inch, on my acrylic bathtub floor. The tub is a Kohler Devonshire 1357 about 14 years old. Tub looks almost new, crack looks superficial just the acrylic surface. I can’t see it underneath because it’s on the opposite side of my access but the tub has what I believe is a fiberglass backing and I can’t imagine it went through that.
Is this something I should repair with a kit they sell at home improvement store or will the crack expand in the near future and should just look for new tub? Will the repair look descent, it’s a very small crack and doesn’t seem to flex.
Thanks!
