New shiny black floor and glossy white cabs installed - cambria charston quartz countertops to be installed soon. (dark charcoal marbling with flecks of cobalt blue) - the wall over the sink needing backsplash is lumpy and would cost $700 to prepare for a glass tile installation - looking for less expensive alternatives. No longer sure stainless steel panel or tiles is what I want - concerned it will be too industrial looking - wanting something softer, but easy to install and clean. Help!
