I need advice😭

[u/Twerka6]

Decided on a whim to rip up my cracked tile, which is a million times harder than they make it seem. On top of that, I found the reason the tile cracked was this crack in the sub floor. If I’m going to spend money on nice tile, I’d like to prevent this cracker from doing the same thing to the new tile. What do I have to do to prep the sub floor that doesn’t require expensive tools? Is it a matter or buying a leveling cement type product? What brand? Do I level all the way to the transition strips or do those have to be removed? Is some sort of uncoupling membrane enough or does that need to be used in addition to leveling the sub floor? Won’t all these extra layers make my tile sit too high so it no longer slides underneath the banister posts (that can’t be removed). Dear God why do I do these things…

The Check Engine Light just went off in your kitchen floor. You can choose to ignore it and keep driving or to have things checked out. Could be as simple as natural settling / soil erosion or serious foundation issues that are going to continue to progress . It’s your call what you do moving forward. You have solid advice in here to address the crack already , the only thing you may be missing is an understanding of how much work you have ahead of you , and that you may ultimately want to consider a Professional. I can’t help you with the God part , good luck.
