It is heavy and you will proably have to install some new sub floor because you need a very stable floor for tile, why not look at the luxury vinyl plank flooring that is now really beautiful and would save a lot of hassle can be installed over existing subfloor and looks awesome. These pics just a couple of examples

Thank you but I really don't want vinyl.

A lot nicer to walk on than tile and I have seen designers now using it in some very high end spaces, I have it in my walkout and i love the look, I think you need to go see some of it in person before you count it out we are talking about 2 finishes that are not real wood and one is going to be a real hassle to install and noisy on a second floor.

What makes your second floor and different then your first / main floor. In wood frame construction, the framing technique is very similar. I've never heard of such a thing

First off, it is beautiful. You should go to some new showrooms that feature Shaw tile and stone and Earthwerks ceramic tile that looks like wood. And it is becoming more practical and doesn't really feel like tile. Although, b/c it is tile, it stays cooler. We are in Houston and it is very hot here. My hub and I work out of our home and we put a lot more wear upstairs in our office areas than downstairs. This type of tile/stone is hard to damage. It will def be more expensive because of the prep work, but the prep work actually allows everything to move. Again in our sandy area, our foundations constantly move. But it will be expensive.

I agree with sswann22. I have installed Earthworks ceramic wood tile for a client, it's
beautiful and durable. Just make sure you get a good tile installer and he uses a good membrane in between the sub floor and tile. We installed it with a zero grout line to give it a more natural wood look.

Sweetlake, thank you for your input. zero grout...I will remember that. Did you put it on the second floor? We have been told about a specific tile installation process...forgot the name. Has a long guarantee.

Awesome. Thank you for that video. It confirmed what we've been told. Yes, the Schluter System was exactly what was recommended. Thank you again. I'm taking this as a sign. :) Have a blessed day Sweetlake! .

Sweetlake, do you have any pictures?

You can go through my projects, I use the wood tile in my flooring designs. I mix it with travertine sometimes... This is a link to a picture. http://www.houzz.com/projects/356713/Heights-Renovation

Beautiful! Thank you!!

sswann22 I have the same idea and feedback from my installer about the wood-like tiles. I was wondering what did you decide on the wood-like tile for the second level of your house?

Well, we just loved the real wood downstairs that we went ahead and continued the real wood upstairs and put a marble look ceramic in the bathrooms. This way the floors flow all through the house. The only floors we have not redone are the kitchen floors and I am concerned about having wood in there. We may do them in the next few years, but I am going to consider seeing if I can match the wood to a similar wood look tile. Not sure. It will depend on what we do with the counter tops. Best wishes.
