Hi Monica,

The splashback in the kitchen is a bronze tint mirror.

This is what was specified below, however the builder may have used an alternative supplier:

Please note that not all mirror products can be used behind cooktops. You will need to check with the supplier if the product you are looking to use is heat resistant.
