This looks to me like a whitewash which is also sometimes called pickled. I can't tell the species of wood. I am trying to do this at our Little Compton, RI beach house and I started with White Ash and am using a 4 part pickling oak stain (Minwax) with 1 part light gray (Varathane). I have done it on a few samples and this is what it turns out like. Next is the poly, but oil based poly yellows, water based poly won't hold up to the elements and I have discovered Swedish acid cures which, from what I have read, should do the trick.
The floor of the bathroom is a Bushmill 4" x 6" running bond limestone by Paris Ceramics 3/4" thick with Laticrete Spectra lock grout, #39 mushroom.
