I've been looking at some more stone for another project - looking at travertine again, i've found some that are 300x600 honed, filled and polished but they're 18mm thick which seems thicker than average - i won't state actual prices as i'm not sure on the policy on that, but they come in around 50% more than the 12.5mm tiles i've sourced previously - is the extra thickness worth it?
