no they don't :ugh::slap:

you don't need to replace shit. You also don't need concrete board, fiber rock, any of that shit for a tiny room like that. You only use that stuff for long spans. I heard somebody say you need joint tape too, no you dont. Just use laticrete or versabond straight onto the laminate or existing subfloor. Home Depot/Lowe's/internet tilesetters/ love to sell you shit you don't need. I've laid thousands and thousands of feet of tile, and have replaced plenty of homeowner do it yourself stuff :rofl:

Look on the back of the product bags, if it says you can lay it straight on laminate (like laticrete), then you can. It sticks just fine. It's made for that.

I haven't been on HAN much lately, if you have any more questions PM me :h5:
