You can build a simple countertop using butcher block, plywood covered with laminate, or stained pine boards. There are many easy DIY tutorials that require only basic skills and tools. The surface can be secured directly to the wall and supported with brackets, or you can simply rest it on the machines if your units do not vibrate heavily.
The added workspace makes sorting laundry much easier and gives you a place to arrange baskets or keep decorative items like small plants or attractive storage jars.
DIY tip: Seal your countertop with polyurethane to make it moisture resistant and easy to wipe clean.
