A: Good Afternoon,
Grout color is a matter of personal preference, and it is best that you ultimately choose what is best for you. Home Depot always recommends Custom Building Products installation materials. #10 Antique White or #122 Linen are both great for coordinating with this item. Home Depot has dried grout samples in the flooring department that you can see and compare to the mosaic prior to making a large purchase. Keep in mind grout can alter the appearance of the glass chips, so take that into consideration when selecting a grout. If you have any further questions, please give us a call at (800)-963-7652. Hope this helps!
