   I'm not sure what you are concerned about, it's no different than putting up smaller tiles. Just make sure you use the correct trowel for your adhesive (thin set) and press them in place correctly.

   *Are you thinking that perhaps a larger tile is heavier, therefore more prone to fall off before set?If that is the case, then be sure to use the correct size notch trowel for the adhesive. For premixed mastic I use no larger than 1/4" V-notch. If using thinset, I use no larger than 3/16" square notch. If no success with the above you can skimcoat the tile back with thinset, or skimcoat the ceiling if using mastic. Let the skimcoat dry or at least wait until after initial setbefore installation.You don't say what key is on the back of the tile; ie, lug. That will definately affect what adhesive and which trowel to use.

   *For any ceiling tile, I use a crib or cripple set up. This is a 93" 2x4 with a small piece of plywood at the end of the board.Trowel on the thinset over the CBU, and back butter the tile. Set the tile and pound it flat.Then using the crib, I place the 2x4 under the tile and place shims on top of the plywood until I make good firm contact with the tile. Jam it in place, and wait 24. Tile stays in place.The set up and cut time of the cribbing is a b*tch. But it really comes in handy to set tile upside down and keep it in place. The last thing you need is to have the tile crash down.PS Do the ceiling first before doing the walls and shower pan. The pan is a bear, and you do not want to damage it!

   *I'm not a tile guy, but I read a great article one time on installing large tiles in overhead places. It was recommended that after finishing, cut a piece of 3/4 or 1/2" plywood the size of your tiled area. Brace it firmly against your newly tiled cieling with 2x4 posts cut to size or posts and jack. Leaving it there until it sets up good in a day or so.
