White trim in the bathroom is fine. Again, using my 80 year old previous residence as an example - the two front rooms, living and dining, had oak floors, doors, a built-in buffet, windows and trim including a 10" baseboard. The rear 1st floor rooms had maple floors, cabinets, doors, windows and trim. Upstairs the floors and trim were pine. Outside the wood was all painted the same. Nowadays most people do use all one or the other, stained or painted. But you can do it the way you want. My bathroom door was stained on the outside and painted white on the inside. It worked very well for the space and that house.

Every house has its issues and only you know how much specific problems will bother you. If the newly installed wood is of the same species and grade, stain mismatch shouldn't be a problem. Different boards will take the stain differently and that will occur in both the new floor and the existing floor. A bit of color variation is part of the beauty of real hardwood floors. If you have the whole floor sanded, you can go with a slightly darker color but stick to a classic medium brown shade and it won't ever go out of style. New engineered flooring isn't going to be as durable as your floor with a good quality finish. Flooring manufacturers tout their multiple coats of finish applied in a factory environment as something that can't be duplicated in an on-site job. True, but that isn't all positive - scratches, dings and dents happen on site and factory finish has to be replaced, not repaired. Rather than replacing the existing, consider spending a bit more money and doing a high end finish. You might want to investigate the newer UV cured coating systems that are marketed as comparable to prefinished products. When my hubby was curious about off color stained wood, I asked him how much the slightly mismatched stain color in our current house bothered him. He hadn't even noticed it and it's been there close to ten years since I removed the carpet exposing the original finish hardwood.

The one thing I know about Pro Classic is it is best to let a professional painter use it. My painter was telling me that it dries so fast, that going back to touch up a missed spot is almost impossible. He thinks it is the best paint for cabinets and trim, but you have to work fast and know what you are doing. Put it on eBay….someone will want a $70.00 can of paint at discount.

I favor traditional furnishings too! I would go with a hand made, hand-knotted Persian carpet every time. Even if it doesn't have your stated preferred colors, a Persian carpet will fit in every decor, and many of the Persian carpets do have more subtle colorways. For example Nain, and Isfahan. Just keep your eyes peeled, and don't be in a rush to buy. Quality in craftsmanship is most important in a handmade, hand-knotted Persian carpet. Don't settle for a cheap imitation. These days the market in Persian carpets has sunk to abysmal lows. That is great for the American buyer.
