They are the cheap version of benchtops. We have one in our current kitchen and, for now, it is totally fine. Not beautiful but functional and looks pretty good. In a world of stone benchtops (seemingly) they don't stand up to comparison however. But, if you go with it and you are happy with it it doesn't really matter what everyone else has! If you want to compare go to a shop like Laminex and look at all the different types they have. Other people can advise more on colour...

love your Jarrah floors with grey..have you considered paving paint as the cheapest thin grey coloured flooring??

Difficult- the tiles and floor match beautifully it's just the laminate. Don't think brown works as grey tile has blue undertone Have you tried a navy against the tiles? I have navy laminate in one bathroom with osprey ceasarstone benchtop and warm grey tiles and looks great Thing is though laminate mist has to go with vanity top and splashback so if marble feature only above bath then could use White as clashes with marble but nice with grey tile and floor So hard nearly there

Don't choose a concrete-look benchtop from a photo. Have a look at real-life samples, see how they feel to the touch, and consider how the edge is detailed. Are you building new cabinetwork that has been designed for the extra bench weight if considering a cast option? Or are you replacing an old bench top over existing cabinetwork? Lots of companies, such as Laminex, produce concrete-look laminates which are lightweight (compared to the real thing), cost-effective, and easy to keep clean but aren't as durable as the heavier options such as Dekton and Ceaserstone. Your choice of edge treatment and a drop-in versus an undermount sink will also affect the installation cost. A lot comes down to your personal preference (especially the touch part) and budget, so do your research. Concrete and concrete-look benchtops are very much an on-trend fashion item and in 2028 they will seem very 2018 so consider your options for the long term wisely.
