We refer to this style of tank an Eastlake” tank. this one’s made of Ash, we suspect, and it’s been refinished. there are some spots of fill on the right-side base, see the photos in the gallery. The bottom does show some water staining, there’s nothing we can do about this. This tank measures 21 5/8″ wide, 10 3/4″ tall, and extends from the wall 10 3/4″. We will install the interior “guts”, and they will come in your choice of 5 finishes.
