This laminate counter was mitered and custom cut to fit around the window opening (which is one viable option).  Because of the U-shaped pattern of the cabinets, we asked that one miter (the left) be pre-fastened at the factory, while the other was left unattached for easier installation.  It installed quite smoothly.  In addition to the counter, we installed the new, stainless 8″ deep double sink and fixture, as well as the dishwasher drain and mini-vent pipe inside the cabinet.  I charge a standard flat rate for these services, so call for details!  419-212-3200
