Hey billymac,
Sorry, I can’t answer your question about the stamped concrete. Ours is actually marble pavers in a French layout...I think they called the pattern. Wish I could help out on the stamped concrete. Several of my neighbors have it and it looks great. We had a small area so we went with the real stuff. If it had been more we wouldn’t have. It already has some staining so concrete may have been a wiser choice.
In regards to the steps, it’s a local company out of Dallas that my hot tub supplier uses instead of the Hot Spring branded steps. I’m sure they are cheaper for the company than the “real” ones by Hot Spring, but they are really sturdy. I just really wanted the matching everwood steps. Let me know if you still want the info on them and I can try to find out more info?? Just keep in mind they are real wood and likely will need paint upkeep over time. Good luck with everything!
