There are many reasons to select a Santos mahogany floor. The species of wood is very durable to decay resistance. It's priced reasonably for an imported hardwood. It's significantly harder than most domestic species. It's typically available without too much delay and is a sustainably-sourced timber.
But the best reason to install a Santos floor in your home is its beauty. Santos is not generally offered in multiple cuts like oak or American cherry; every cut of wood is generally available in a given bundle of flooring. This means a wide range of grain patterns and color will be present in the floor, yet the variation does not result in a "busy" or distracting floor.
There's a reason Santos mahogany is the imported wood of choice for board rooms, attorneys, upscale bars and guitar makers alike--it's beautiful.
