Put the marble and travertine in the bathrooms and keep the floors.

I appreciate the honesty 😆 I talked to a few refinishers in my area already. The veneer is so thin that it can only be refinished once, but because it has the hand scraped look, it can’t be refinished or recoated at all. I believe the pictures make the wood look like it’s in better condition than it is. The specks in the picture below isn’t dust. I don’t know, maybe I’m being OCD lol

Your floors have naturally occuring character!

I really dislike tile in all spces it is hard on feet, legs and backs. I would actually do LVP before I would do tile everywhere . I do not like wood with pets it just does not stand up over time. but a at least do solid if you want wood .

Would love to go solid wood, but I live in Southwest Florida. Too humid

I just replaced old engineered hardwood and carpet with new engineered hardwood everywhere, and couldn't be happier. If you take reasonable care of hardwood it lasts a very long time. You can't really refinish those hand scraped floors. In a previous home, I had natural travertine floors and although they looked nice they were very hard to stand/walk on, and they got small pits over time that were difficult to fill. If you like the travertine look you're better off with a porcelain tile that looks like stone. But with the style of your home, and all the stone accents, I think new hardwood would look the best.

I like stone in Florida/hot climates. The stacked, matte stone, throughout the space WILL limit your colour range. You will need to look at gray, some gray, or maybe some gray. Right after that you can look at gray.

Travertine can be matched to some of the gold/cream coloured stones. The GLOSS level is going to be very low. There are ways to keep it low gloss. There are sealants that keep it low gloss.

The stone will be tough to keep from staining AND etching. Thankfully the natural colour of the stone will help hide these stains and etchings.

If you are 'ocd' then you will need to be VERY aware of what you are about to do to yourself...stone is stunning...but can have all same AMOUNT of issues with wood. Just in different ways.

We had laid and finished in place hardwood in our Texas home. Probably as humid as Florida but never a problem. A/c was on almost 24/7. Just my experience. Good luck to you!

The finishes used on engineered flooring today are probably much tougher in the higher quality products than what was used almost 20 years ago. I would look into that option first.
