Can you fit a waste disposal unit under granite or quartz worktops?
The short answer is Yes! Yes, of course you can. They are not as popular as they were, but we still see significant numbers of waste disposal units being fitted under quartz and granite worktops. Probably the biggest brand by frequency would be Insinkerator, and especially their state-of-the-art Evolution series, but we see others too.
There are just a few issues that need thought when fitting a waste disposal unit under granite or quartz worktops – or any other kind, for that matter.
