Oh and when I started tiling, I drew a level line about 1 ft up from
edge of tub, screwed a level support base for the tile (1x2) all along
the edge, and tiled that first, and tiled up to the ceiling (or
whereever your top edge is). Then removed the support strip,and used the
blue tape to support the last 2 rows of tile. Get your measurements
correct for the support strip, and you shouldn't have to cut the last
row of tiles (too much). Oh, and some might say different, but the 1/4"
hardibacker is plenty stiff and rigid for wall use (according to two
tile pros I talked to-that is all they use), and is soooo much easier to
work with than anything else out there. It has held up fine in my
application for 5 years. 16" on center is OK I think, for verticle
support studs. They also reccommend horizontal support at the edges.
Stay away from the Durock. Messy, and freakin HEAVY.

I'm in the process of remodeling my bathroom. I tore out the
solid-surface and drywall that was under it. I'm putting in a
fiberglass shower pan insert. I'm thinking of using felt, backerboard
and then tiling over that.

My question is, the flange of the insert sticks out about 1/3 of an
inch. So, I'd have to use furing strips, correct? However, what about
the transition from the backerboard to the drywall (about 6' up)? The
backboard will be sticking out about 1/3" of an inch. How do I go about
this problem?

Thanks for any advice!
