What would be the correct anchor to attach a sliding shower door (the weight is supported by the tub, the screws in the wall just hold it upright) to a tiled wall? The anchors that came with it look like they're for a thin acrylic tub surround. The wall is made of cement backer board with thick porcelain tile on it, probably about 3/4" to 1" thick total. Also, the H-shaped track has some distance between the screw hole and the wall (11/16"), I'm not sure if that has any effect on what to use. It's just that I searched and can't really find any place that says what anchors to use, so I want to make sure.

plastic wall anchors are what you need.. they often come with most peices of hardware however are junk.. too brittle and dont perform.. your best bet is to go to a building supply and buy them there..

mind you when i frame up for showers getting glass doors we put backing in where the door will go so we know the frame will be screwed to framing.

anyhow.. you wont just be using the anchors to hold it to the wall, the track has to have a bead of silicone behind it for waterproofing.. once it cures it will give extra holding power

Cheap plastic anchors just tend to spin. If there's no backer for real screws you may want to concider using toggle bolts.
I agree 100 % with the other poster, I always use 2 X 6's at the edge of the tub so someone can install a curtain or a door.

Is this the kind of thing you're talking about?

Sadly we didn't think of that at the time. I doubt that there's wood behind there.

If there's no backer for real screws you may want to concider using toggle bolts.

My main concern about toggle bolts is that with the large hole, small screw, and the fact that there's some room between the wall and the screw hole, they might let the frame slide side to side a little against the tile. Is that a real issue?

Nope, not an issure if you use silicone between the trim and the wall.
