We have main hallway and rear hall done in
Travertine - TT34 Sandstone 35m2approx
Very hard wearing, high traffic area
easily sweep and kept, we didn’t use the sealer/topcoat this time.
Only down side - minor repair in concrete floor prior to the Karndean been laid shows through.
Its not cheap, but is a lot "warmer" that a tile finish.
We got ours from Matt Brittons in Kilcoole.[broken link removed]
