A painted design behind glass mounted to your wall is easily changed, should you become tired of it.
Larger tiles mean fewer grout lines. Epoxy grout is more easily maintained than sanded grout.
Any wood product must be very well sealed to withstand food and liquid splashing, heat and humidity. Your home's humidity level should not exceed 40% and regular use of a very good exhaust vent is required.
