Adhesive/tile thickness unused fireplace hearth

[Mrxman]

Hi there

I want to tile an unused victorian fireplace hearth and would like the tiles to be flush with wooden floorboards.
I've found 10mm thick tiles I like but they sit only 1-2 mm below the floorboards without adhesive.

What adhesive thickness would be ideal for this scenario? Would 1-2 mm adhesive be enough?

Also, the tiles I have in mind are 45cm x 45 cm which. Is it easier to tile with smaller tiles or doesn't it make any difference?

Thanks

As the tiles will be retained by the border of the hearth, effectively held captive in a rectangle then the thickness of adhesive will not be too critical and you could even use contact adhesive as an option. As for tile size a bigger tile means fewer joints to level so could be easier if you have limited tiling experience.

Thank you. Much appreciated, really helpful.
