Standard stains come in (a variety) about 35 colors. Most of the stains are a variety of browns, with variations in hue from reds to golds.
Process to lay a great stain requires a lot of preparatory sanding for the floor. Normally a stain job will add an extra day or two to a normal 3 or 4 day process. Of course the larger the job the longer the process. Some available colors are presented.
