Hi mluh You've obviously done your research on these products, so it's most likely going to come down to personal preference. As you've mentioned, a natural stone is going to come with an amount of maintenance but the beauty of Travertine is within its variation. Once sealed with a good quality sealer (I recommend Guard Industry), the maintenance is really quite low and most spills are lost within those natural variations. 99% of spills can be cleaned up without too much trouble. Porcelain, on the other hand, can be quite difficult to clean once it's been marked. That said, the external porcelains have a great non-slip texture and are very hardy when used as paving/tiles. I'm personally not a fan of using them as pool coping, but many people love it. Again, both have their advantages and disadvantages so I would recommend using the product that you're happy looking at for the next 10-20 years. - Jordan

I am no expert but I don't think they will work together. To me they are two different styles and if you use both it will look like a compromise of two clashing styles. I think you need to fully embrace the rustic or the vertical, use one of those as your feature and build around it. Question is; which one? Flip a coin?

Hi Michelle, \ We sell Travertine both silver and premium classic, it has been used for outdoor pool area and patio and we have never experienced the material getting heated under the sun. But you're more than welcome to pick up a free sample and leave it out and see for yourself. 190 Victoria Road, Marrickville
