Can i use 1/2 inch cement board for a sub floor in my kitchen had flood ripped up old sub floor now instead of putting new down would like to use 1/2in cement board 

They have Hardie board cement panels is one option.

I can’t speak to the numbers since I have not seen complete plans and specs and finishes level of construction site conditions etc. but overall they look average for a typical straightforward project with vinyl siding or fiber cement siding shingle roof mid grade level of finish.  

if you will not be i would do as @Ricardo Meza said and carefully remove the grout, but be careful trying to break the tile out with just a chisel, any pressure against surrounding tiles will chip them. what i would do, is take a grinder with a diamond blade and carefully make some cuts, cutting out the towel bar holder and a couple cuts in that tile ( being careful not to hit other tiles), this will make release cuts so that the tile will remove easier with the chisel. the towel bar holder is cemented into the wall, when you get it out there will be a hole in the wall there.

I was steering towards the same line but the reasoning from each of you truly cements the idea and the process. 

Which generally means that it is off the axle and on cement pillars with concrete skirtings and depending on what state hurricane strap down/tie downs. 

I eventually found a good roofer, siding guy, asphalt/cement/paver guy, all around handyman, electrician, and my granite place.

I am going to be putting in new floors in the living room and dining room of my condo, and the cost to install hardwood isn't greatly different from having someone professional stain the cement.I know the stained cement would be more durable and less maintenance, but I would like to know other pros and cons of both options.

Hey all,I am looking at a 4plex in Philly that has a cement storage area attached.

It was cemented in and fenced.
