I'm in the planning stage of remodelling my bathroom. I want to tile the
floor, and have been given enough tiles to do the job. The only slight
problem is that the tiles are 30cm a side, and I've been warned that if
the
floor isn't 100% stable they'll be liable to crack.

The boards under the carpet are currently 60cm wide, not sure how long as
I
haven't pulled up enough of the carpet to find out. I'm not sure what the
material is, but it doesn't look like wood. There is no noticeable give in
the floor, even when I jump on it.

Am I liable to have a problem? Should I just aim to position the tiles so
they meet over the joins in the boards, and use a felexible grout?



use a purpose made flexible adhesive for fixing tiles onto wooden floors.
(eg BAL)

Also if boards are not rock solid, put some screws in an 150mm centres to
pull them up tight to joists.

Any advice?

I have avery similar job coming up apart from my tiles being 330mm on a side.
there is some info at http://www.enigmatist.com/free/john49/faq0.htm
Although you might not think you floor moves, I expect it will move enough to
crack tiles.Test it by standing or kneeling on the floor whilst someone else
jumps on it.
Aligning tile edges with board edges will just ensure your grouting cracks.
I will be taking up my floor boards, fitting insulation, screwing thick plywood
in between the joiststo be level with the tops of the joists, either adding
anothe rlayer of ply over the top or putting aqua paneldown, then adding under
floor heating wires and finally the tiles to bring the top surface of the floor
back where the floor boards used to be.

Just athougth but have you tried tiles R us to see if they have a 'how to do
it'leaflet?

Good Luck

And come loose.

Sounds like chipboard flooring panels.

The normal recommendation is to fix 6mm plywood over the floor, screwed in
place, then use a flexible adhesive designed for the job.

so you will be fixing the thick plywood between the joists? I'm
confused why? is it just for strength

It's something I am going to be doing soon so am after as much
information as possible..

People keep telling me to leave the floor boards down and screw
plywood on top of it, then tile on top of that, but I'm worried
because that should mean the tiles are 2cm higher than the rest of the
floor in the house, and I just know thats the edge I'm gonna break my
toes on.

My bathroom floor is 19mm T&G pine. I have had tiles (300mm nominal
square) laid. The guy got me to lay 9m ply over the whole floor
screwed down at 150mm centres. He was quite insistent that it should
be 9mm at a minimum. For all the cost, effort, difficulty and time I
reckoned it was far better to get someone in to do it.
