We considered Quartz countertops (as well as granite and some other recycled material whose name I can't recall) but had to 'settle' for
Formica countertops. We have a large rectangular kitchen and our countertops run along three of the four kitchen walls which is close to a 15 meter run in total. Our cheapest quote came in at around 60K (including installation) if memory serves which was more than three-quarters of our kitchen budget. The Formica tops cost us 8K (including installation). Now that I've seen how the Formica tops are installed, I'm pretty confident I could do that myself in the future.
I was initially disappointed that Formica was one our only affordable option but honestly it's been great so far. The colour we chose contrasts perfectly with our cupboards. I was also surprised that everyone we've shown the kitchen to has loved it so far. I guess I was expecting a little more snobbery in that regard.
I was worried that the surfaces would damage easily but as long as we keep our cutting and chopping on a cutting board it looks like these will last us a long time. And honestly, I could replace the Formica tops on a yearly basis for the next five years and I still wouldn't reach the cheapest Quartz quote we were given.
I do realize that Quartz or Granite is still the superior option and it's obviously still nicer looking compared to Formica and other cheaper options but it's definitely not as bad of an alternative as I initially thought.
