We have had installed an acrylic shower base (Americh), and are having

AFAIK, it is customary to use caulk at corners of wall to wall or wall
to tub/shower, the reason being that there is always some degree of
movement or expansion/contraction expected. Americh's installation
instructions appear to agree, he

Silicone caulk would be my choice.
