Hey, Welcome to TFP!
Pebble finishes are comsidered to be longer lasting than most anything except tile. Now there are thermo-polymers in play as well. Even a very good plaster job can easily last 15 or more years if it has a good life. Quartz will be smoother and cost less than Stonscapes, but it really comes down to personal preference. A well done Quartz or pebble should easily last 20-25 under good conditions. The Blue color you mention is very subjective, so are you thinking light, or dark colored finish? I prefer lighter ones by far, but there is no right or wrong color. So many options. We blended two colors for ours, but It's a different high end brand. The most important thing is getting a good applicator who cares about his work, because the quality of the job is way more important than the brand.
I'm going to discourage you from the in-floor system and suggest a high quality robot instead. Mind you, we don't hear much about the ones that are running great, but only those that have issues, and we hear it frequently about all of them. Repairs are a real PITA when sprayers get stuck up or down, and they just seem overly problematic. At least for my taste, and a high quality robot cleans more thoroughly anyway. They also don't remove leaves or other debris, so you're left with that as well. Just food for thought, but there will be others weighing in and sharing ideas, and hopefully some colors for you. We are all about tight Chemistry control around here, so you came to the right place for that. Hope you enjoy the forum.
Cheers!
