How do I fill a gap between wall tile and acrylic shower base

Question

The bottom row of a newly installed tile wall has a gap with the shower base that is about 1/2 inch wide, too wide to caulk. How can this be filled in a way that will not crack, will make a water tight seal between the shower base and wall and can be kept clean. I am afraid I would damage or ruin the whole tile wall if I tried to remove the bottom row of subway tiles so I could replace them with custom cut tiles that would fit without a gap

Answer 1

If you have access to the same tiles that you used, you could cut them to size (you may want to consider using a good cutter or wet saw). That way you can caulk the space in between the tile and the acrylic shower base. If you don't have any extra tiles or can't find any more of the same type, you could find a nice complementary looking small tile and install that instead.

Answer 2

Fill the space with grout and then clear caulk over that
