Larger plank sizes can look more striking when installed in the right setting. Sound-Tec Plus has a size of 9” x 60”, an upscale look compared to other planks sized at 6” x 36”. As with many things in design, beauty is in the eye of the beholder. While plank size does alter the design of a room, it doesn’t improve the durability of the product. All floors remain waterproof and durable no matter their size.
