Compare Refinishing to the cost and pitfalls of bathtub liners
Bathtub liners are a much more expensive method of restoring an old bathtub.
Sometimes water seeps in between the liner and the old bathtub. This stagnate water can then lead to rusting problems and foul odors.
Bathtub liners may also form cracks caused by excessive gaps between the liner and the bathtub or from the hydrostatic pressure of the water underneath.
The liner in the first picture cracked, was removed and the bathtub was refinished.
After the cracked bathtub liner was cut in two, I was able to take measurements and pictures, showing some potential problems.
The second picture shows a crossection of the bathtub liner. You can see how the thickness varies from thick to thin. This wouldn't be obvious if you only looked at an intact bathtub liner, because the only edges visible are the "thick" ones. You can only see how thin it is in some areas by cutting it in half. How much does it vary?The third picture shows what the bathtub liner looks like at an outside edge. It appears to be plenty thick and strong, about .275".
The forth picture shows how thin the bathtub
liner is at the weakest point, which was only .045"
The sixth picture shows the original bathtub refinished, with the
bathtub surround reinstalled.
