Worktop express solid laminate, basically layers and layers of laminate rather than typical laminate on a chipboard base. Got the cuts measured and cut to size once I fit the units and I drilled the sink/tap holes to suit (saves any errors in dimensionsThat's banging. I have a lot of time for the plumbing too!
What worktops are they?
