Before - Dam too high to step over.
After - Finished - Dam cut down to allow easy entry & color matched.
Process - Problem, dam too high
Map out the cut lines & protect the tub from damage.
Entryway cut out.
Checking the right tilt, for any water droplets, that gets on the dam to flow back into the shower.
Ready to spray - The voids filled in, room protected ... notice the "Fume Extractor" that sucks the air from the rest of the house, mixes with the fumes in the bathroom & blows it through an 8" flexible pipe out a window.
Another finished view, color matched.
