I am building a shower enclosure around my bathtub and then tiling it. I need to tile up to the edge of the tub (as opposed to the new drop-in tubs which have sit on top of the tile). I am using Hardibacker (a new, to me anyway, type of backerboard). How do I go about tiling this rim/edge around the tub. Do I need to put plywood around the edge and then cover that with Hardibacker/backerboard and then tile onto that. Or can I just put Hardibacker/backerboard? Or can I just tile directly to the tub itself (it is an old porcelain covered iron insert). Because I am building an enclosure, I probably will need to get some sort of support from the edge,so I am thinking plywood andthen backerboard. If so, do I just cut small edge tiles to fit that small edge all around (it will be the width of the plywood and backerboard). It seems like a pretty small edge and that the tiles would be liable to fall off or chip off. Anyway, any advice anyone can give me will be much appreciated. Thanks. Pete

In preparing to tile my countertop and backsplash, here are some things I'm receiving conflicting info on :wall: : 1. One source says to use 3/4" plywood and THEN 1/4" backerboard as underlayment, other sources say just use backerboard. Also, if I go with the plywood AND backerboard, and THEN tile, the backsplash will end up extending out an extra inch and a half from where it is now. That would put the backsplash OVER the back edge of the sink. :confused: 2. If I just go with the backerboard, I've had one source say it should not be attached directly to the studs, and a bunch of other sources that say specifically to attach it to the studs using 1 1/4" glavanized screws or nails every 8 inches. :confused: 3. I've had one source say not to seal the grout on the countertop because food is put there, yet other sources comment on sealing the grout after 24 hours. Given that the countertop is exposed to water and other liquids, wouldn't you HAVE to seal it? And if so, what kind of sealer do you use? 4. Lots of conflicting info regarding a waterproof membrane. Where should it go, should I use the paint on type, and if not the paint on type, how do I secure it down so it doesn't move underneath and crack the tiles?
