[Shop-talk] Caulking large gap

[Jim Franklin]

I cut the bottom course of tiles too short and now have a 3/4" gap  
between them and the tub. The backerboard is also trimmed a bit high  
so I can't cement thin slices of tile in there. I think it would look  
hideous with the gap filled with caulk, even if it was applied neatly.  
Anything to remedy this? I suppose I could lay down a spacer, then  
fill the gap with mortar all the way to the tub flange and put thin  
tile slices into that, then caulk the smaller gap where the spacer  
was, but mentally I was done with the mortar and don't really want to  
start that up again. Plus it would announce the screw-up moreso than  
caulk :-)

thanks,
jim
