Rip up the laminate out and put down cement board first secured with screws,the mastic for the tiles will not stick to the plywood.Laminate flooring in a bathroom is a huge no,will buckle due lots of moisture.

Rip out the old laminate, . If the subfloor is in good repair (no water damage) then screw down fir plywood with the screws every 4 inches square. If you're using ceramic tile you will want to set the tiles with thinset.
you do not need cement board if the sub-floor is concrete..only if the sub-floor is wood then the cement board would be used. and it needs the special coated screws. ask the salesmen, to direct you to the correct screws..do not use black drywall screws you may..if you want..use the cement board to raise the tile to match existing wood floor or carpet or whatever you have. when you tear out the laminate..you need to get the glue up also..scrap it and use a acetone to chemically loosen it. ACETONE IS FLAMABLE OPEN DOORSAND WINDOWS>>EXTINGUISH ANY PILOT LIGHTS AND NO OPEN FLAMES IN THE HOUSE NO SMOKING<<<<<<<<<<you can buy a scrapper on a pole at the hardware store, it looks like a hoe..but is straight..if you have a grinder sharpen the scrapper..worked better for me.. also buy a hand scrapper..with changable razor blades...........opps I forgot..removing the glue..is not needed to do..if..your installing the cement board..only if its a concrete floor and you are installing tile di-rectly ohn it.....I would like to add..the acetone.. only use on spots that won't come up.. not the whole thing

I also agree that tile can't be applied over laminate flooring. Remove it. Check the thickness of your subfloor. If it 3/4" plywood, do as suggested add a 1/2" exterior grade fir plywood screwing it down to the subfloor every 4" across the surface and all edges using ceramic coated screws. To this you may apply ceramic tile but use a thinset mortar with a latex addictive designed for use with applying tile to wood. I've used this method on several tile jobs in my home and all have stood up well and have not been a problem.
also..scrap it and use a acetone to chemically loosen it. ACETONE IS FLAMABLE OPEN DOORSAND WINDOWS>>EXTINGUISH ANY PILOT LIGHTS AND NO OPEN FLAMES IN THE HOUSE NO SMOKING
Now there's some really bad advice even with the warning.
why is that bad advice? I used it on my floor, out in texas, had some spots that would NOT come up..it worked!! now granted..if done like an idiot. closed windows and pilot lights left on, and a fool smoking your looking for trouble but if done with intelligence, its ok
