You could use Schluter KERDI to seal the backerboard and the joint between
it and the shower base. An 1/8" gap could pose a tile laying problem when
trying to fit the tiles against the base, doesn't the shower base have a lip
all around that fits behind the tiles to aid in waterproofing the joint?


The 1/8 inch gap was what was recommended on the installation
instructions for the backer board. I guess I'm just figuring since
that piece of tile will not be loaded it will be OK to overhang the
edge of the backer?

The shower base doesn't have a lip, it just goes straight down and
sits directly on the subfloor without any kind of flange or lip.
