Small master bathroom in flip, is tile in the shower better than a plastic surround?

[Letitia Harris]

I'm debating if tiling the master bath shower is better than a plastic surround.  It measures 32 x 32, 72 sq. feet,  in a VERY small bathroom in an inverted L shape.    The main hall bath has a soaking tub and shower, with a nice shower surround.

Also, is a pedestal sink a better option than a 14" vanity?   

Thanks!
