Going to need the joist size, spacing, free spans, also what type and thickness of sublfooring you have now.

Not going to do you any good to tell you what it should be until we know what you have now.

Any tile floor can not have any movement under it or it will fail.

I am having a new bathroom and wanted laminate. My fitter said "no" apparently even the stuff sold as moisture proof bubbles after a certain period. He said if you don't want tile get a quality vinyl instead.

Bren, please go back and add your own post and not add onto someone elses.
To confusing.

Ok so the flooring under the laminate is the original flooring from when the house was built. So where do I go from there??

You need to let us know what size you floor joists are, then the thickness of the subfloor. then you need to see about the span of the floor joists.

Is your house built on slab?

Ok well I again am probably over my head here but I refuse to hire someone and learn this myself! I have no clue about a slab or no slab!! I have an unfinished basement is that where I check the joist and subfloor thickness??

your basement is where you determine the type of floor joists. it also is where you check for the supports for the floor joists.

under where the bath is, measure the with and height of the wood.



The joists are the long boards supporting the plywood.
