What to use to fill the gap between the shower base and the floor?

[Sylvian]

I have tried a strip of UPVC but it was not pliable enough. I also enquired about bendy MDF but there is no local suppliers. Any other ideas?

Ideally, that would of been set on a base, then you could of tiled it to match the floor

I'm no expert, but there seems to be several things wrong here. How bad would it be for you to completely remove the shower pan and start over again?

Basically impossible now, the tiling flange is in the wall. Just going to have to build something around it, I have a feeling any flexible material you would wrap to follow the contour of the base will look like crap

I'd recommend getting some form styrofoam...the same stuff used in construction around exterior window casings, then saw cut 2" x 8" and mastic them around the base in a vertical direction.

Here is a pic of a similar look, which is shown on the steps leading to the tub.
