Now you got me started. I was going to comment that the molding and the floors look wonderful and should stay the colors they are. In many older houses with stained ww, the floor is lighter, giving some interest to the room. Then you got me started on base shoe, my FAVORITE topic. IMHO, you must put the base shoe up. It's the finishing touch on fine woodwork. I've always wondered why it is called base shoe and finally determined that it's like putting on your best clothing and then going barefoot. It just looks unfinished. My former house had all natural molding, what I wouldn't give to have it now. I love my house, but the white moldings can go...and the upkeep. My guess is if you're using the original baseshoe and it's held up all these years, it'll will hold up for many more. New stuff, unless you buy oak, not so much. Have fun. The house is beautiful.

Gel stain, yes; Polyshades, no. Gel stains work very well on pine because they don't penetrate much and thus avoid blotching (uneven absorption of color due to uneven cellular structure.) Polyshades is a varnish with a lot of pigment. Sort of a halfway point between varnish and paint. It is very difficult to get it on evenly and without streaking. Realize that the pine will never match the oak as they are radically different grain structures. The best you can hope for is a similar color.

Thank you @aziline!! I talked to Shaw. I really think they manufacture coretec also ... I didn't ask but one of the products they recommended was by Coretec. Anyway, the person I got in touch with has the same cabinets as me. She gave me a few suggestions. LARGO MIX PLUS GRAN SASSO JATOBA CASA PLUS GRIGIO LARGO MIX PLUS CAMPANIA JATOBA Edinburgh Oak I haven't tried any of these. The coretec she suggested has enhanced bevels that I have been avoiding. Therefore, it might have been at the flooring store but in the section I wasn't looking. I haven't taken home any of Shaw's products. I really haven't looked at Shaw. I didn't really want varied length boards but I will overlook that as long as I feel it will look good in the space. I also don't think the tile would look good on the whole floor. Maybe in the bathroom but not the entire space. Isn't remodeling suppose to be fun??!!

One other way is to stain match calypso oak with full treads and risers. I prefer this way, but a larger investment and takes wood floor professional to achieve.
