Looking for some guru sage advice :-)
You can follow my lovely house here: My new house and the progress I make.
However, I'm working on the hall bathroom:
(and realized I took super crappy "before" floor shots...)
I removed the vanity that was in there... And in the process learned the hot water valve was corroded open... Besides one incident where I thought the hot water was completely turned off when it wasn't flooding the bathroom a little bit I got the valve replaced no problem...
Then I pulled the toilet, then I pulled up half the floor (The easy/damaged half)
Now I have this: (looks better in these photos than it did... I sprayed it with bleach last night to ensure any mold was dead...)
So now I'm trying to figure out how to proceed...
I was recommended to let the plywood dry, throw 1/2" hardibacker down (liquid nailing it over the joists and screwing it down) and tile on top of that.
After further research even if I do the 1/2" hardibacker I'm going to be using thinset under it...
My floor is 1/2" plywood over 9" beams that can support ceramic tile according to the johnbridge.com calculator.
There's some warping of the plywood by the toilet...
I'm considering replacing that plywood instead of just going over it... But I was thinking of cutting out the damged section (leaving the 4" section next to the wall) and then replacing what I pull with 3/4" plywood and adding 1/4" everywehre I don't replace...
My goal is to have the tile end up nearly level with the hardwood floor elsewhere in the house... That floor is 3/4" hardwood over 1/2" plywood.
After putting my plan above in words I don't like what that'd do to the seems... So maybe replace the damaged 1/2" with new 1/2" and then lay 1/4" over the whole floor, with 1/4" hardibacker or ditra and then tile on top of that?
suggestions more than welcome... They're being looked for :-)
(also... is there a way to thumbnail images easier? or am I just using a bad host (photobucket).... I guess I could be using a good host badly....)
