Too modern and more expensive to do since the home is already built. It will cost more than installing wood floors or tile at this point. Not to mention how it will change the acoustics on the home. Polished or stained concrete floors needs to be decided when they are pouring the floors for a really successful outcome.

When you take up the carpet, you may find the slab not level and has been filled before the flooring was installed. Just can't do concrete at this point.

I do not see much traditional molding except the odd piece around that one place which really makes no sense at all the rest of the trim is cheap everyday trim as are the doors. If the tiling is cracking you have a problem with the sub floor having too much movement so that would have to corrected before concrete floor could be done but you could put concrete in once that is done but it is a much more contemporary look so I would check to see what other houses in your area have for flooring. I would also remove that weird piece of molding that connects to nothing.

Agreed with other poster, after the fact concrete may be difficult. You can stain it, however, so you may find something that works with your decor and style so that it doesn't clash, which appears to be a concern. It would be best to get a few estimates and determine with an installing company what the process and costs may be. Any foundation or subfloor issues that may be causing shifting and cracks would need resolved as previously stated.

we rather liked the "luxury" vinyl we installed. It can be grouted, is much more flexible (and less cold/"hard" feeling than tile), much less expensive. Flooding may still poss an issue but something to maybe explore?

There is a really cool flooring from Mannington called Adura Manhattan in the brushed steel that might work it will work without worrying about fixing the structure for concrete or

Hello, fellow Houston resident here! Love your odd bit of trim. It works here, IMO. Check how much a danger flooding is for you. We had hard wood floors installed over concrete last summer. My neighbor tiled her downstairs, with hard wood only in the dining room. I agree that your foundation most likely has issues if tiles are cracking and that the concrete is too modern for this house. ( I had to give up tall baseboards to get wood everywhere on my budget.) Pictures while work was in process.

I agree, if cracking tiles there is probably an issue underneath, definitely have that checked out. What I think would be a great solution to your problem is having hardwood tile installed. It gives you the appearance of real hardwood yet is durable and safe in the event of flooding. Good luck!
