If you are talking about ceramic times you really need to board out the floor with either a Marine grade ply (up to 15mm thick is always recommended by adhesive manufacturers) or something called Ditra matting. Board is a simple option..... you must leave a 6 - 8 mm expansion gap around the edge. The boards must be screwed down with 300mm centres or less ( a screw every foot), then sealed using a silicon or PVA bonding agent to make waterproof. Then use a cement based FLEXIBLE waterproof adhesive to secure the times down and finally a FLEXI waterproof grouting. This should work. If your tiles crack then you've not made the floor secure enough, or used the wrong adhesive. Best to ask advice from a reputable tile supplier.... they should know! Take care to get it right first before you go ahead and tile!

I always plywood floors. It is recommended you use 12mm ply or as close to it as possible because of door heights etc... Screw the boards down brickwork fashion with the screws at 6 inch spacing (you'll need a few screws). Then use a rapid set powdered flexible adhesive. Means you can tile so much and in 3 hours time, stand on them to tile the rest. Get Uni Bond adhesive.
I've only done one job straight onto the sheets of chipboard because that's what the customer wanted and two tiles have cracked.
ALWAYS, ALWAYS ply wooden floors. I only use PVA for dusty concrete floors or old plaster.

You need to seal the surface first. As it is in a laundry room you will need to use a waterproof sealant. I presume you are going to use vinyl tiles, in which case I would recommend commercial grade tiles that are not self-adhesive. Use waterproof tile adhesive with these tiles.

The answer is no, in you don't want it to move. You need to put down some plywood at least 15mm first. Lots of screws and then seal. Then lay the floor tiles.

You should be OK as long you pick a tile adhesive that allows for sufficient movement.
