Remove the Backsplash and Countertop
Remove the countertop backsplash by prying out sections, starting in the middle.
Check below the countertop to see if there are any screws or retaining hardware fastening the counter to the cabinets, and remove them. The countertop can now be lifted away and discarded.
If the countertop is very large or an unwieldy shape, such as with L-shaped tops, remove any hardware fastening separate sections together, or cut the countertop into manageable pieces with a reciprocating saw. Before cutting, pull off any metal trim along the countertop or backsplash edge. Use a fine tooth bimetal blade and wear safety glasses when cutting through laminate surfaces.
