Ciot Tile Mark Gypsum Lap. Rt 17.75"x35.5"

Mark Gypsum at 17 3/4" x 35 1/2" is large enough that the subfloor has to be flat first, because a tile this size telegraphs every dip underneath. The look is worth the prep. Fired harder and denser than ceramic, porcelain copes with freeze and thaw as well, so a covered porch or a three season room is fair game. It is on display in Mississauga and Barrie if you want to see a full sheet rather than a photograph.
