One of the many benefits of choosing large porcelain tile (thin slab) would be the waterproofing aspect. You are 100% guaranteed with less joints and the epoxy to have perfect waterproofing for those wet areas of your home, like the bathroom or kitchen. For example, take a master bathroom where water is a factor, the general tile will have many joints which increase the possibility of water penetration hence costly preparation on waterproofing. With Thin Porcelain Slabs the expense will be for the look of the actual tile instead of a contingency plan.
Deigning with thin porcelain slabs, not only look amazing, but will save you money in the long run.
