I bought these to use on my sailboat in the cockpit and the cabin.  They look stunning!  I also use them in my home in the bathroom over the tile.  Where we live there is orange clay outside and the dogs get it on their paws and bring it inside onto my while tiles in the bathroom, so I put these teak tiles down on top of them and I can just lift them and wash them when they get dirty.  I think these would also be great to put over a subfloor then lay them down for flooring in the home.  I do wish they also came in 6 x 6 sizes.  But, I love to walk barefoot on wood and touching earth products, and these teak tiles are perfect for that!  They have a nice frequency and vibe to them!
