Hey guys im looking to get some advice on what i should do for the underlayment for a tile floor in my kitchen. I know i need to have a cement type board down before the tille, but manufacture says to have 5/8 minimum plywood subfloor before installation. the house i have was built in 1850 and subfloors throughout house are 5/4 then have a wood "plank" floor on top of the 5/4. my question is am i good to use what's already there as the subfloor or do i absolutely have to add another layer of 5/8 or 3/4. obviously this isnt a way i want to go. i have attached a picture of the kitchen floor.
