laying tiles in my bathroom

[hotspot007]

Hi everyone.....ok......dont laugh
I want or should I say my wife wants me to tile our bathroom floor with our left over slate tiles from our kitchen. Now its is a newly built house ( 6years old now)..and the floor (is that horrible tongue and groove stuff..thats impossible to get up!!! and also very flexible and creaky!!!..I have tried several times in vain all over the house to stop the creaking of the floor..but have now learned to live with it!!!!!till now....cause now I know i cant have it moving if im going to tile over it...so my questions are???????
1, Can you tile straight over this tongue and groove flooring????
and 2...can you use silicon sealant to put them down with instead of adhesive ( me thinking it would be a, flexible b, water tight c, give good adhesion )...also can you grout with it to??

please be gentle if this idea is totally stupid!!!!!

Any replies or help most welcome...

Screw the tongue and groove (chipboard?) down properly to stop the squeeks.

Use a proper floor tile adhesive. Most say "flexible floor adhesive" on the tub so should be ideal.
