Save your money till you can replace everything with the same flooring. Maybe keep your mudroom flooring, but change everything else to the same material.

I agree with mark. Save your money until you can replace all the flooring at the same time with one (maybe two) materials.

I agree that saving and replacing all of the flooring at once is the best idea. In that case you could replace the bathroom vinyl when you redo it (with tile) and then replace the hallway/kitchen/living/dining flooring with the same wood later on.

If that isn't the route you want to take for whatever reason, then I think a large format tile would look nice. The color of the current flooring seems to go with the adjoining wood, so tile with a similar color would work. You could also look into tile with a light/med gray color, something that coordinates nicely with your counters and wall color.

Hmmm- yes that's an option, but I can't imagine the cost of installing all new hardwoods on the entire floor (and then of course having to tile the bathroom on top of that!). Especially since we need to do the bathroom- the vanity, mirror, toilet and light all need to go. Should I make those changes and leave the floor? Or just tile the bathroom and deal with the fact that there are a gazillion different floors going on??

call a floor refinisher. Professional. get a quote for sanding it down and match the stain on all the floors. See what they say. It's a finesse as they are different species?? but a pro can do it , likely. they will let you know how many of the five they can coordinate. Otherwise....you have a guest room/living room and tv room...CARPET and a pad ….do consider...run it through for continuity, it will make the space feel bigger, and fairly easy on the budget. Your kitchen should have a presence and has a higher price tag when everything is cumulatively calculated....get the floor that works with your kitchen the best..and that you like. Consider carpet elsewhere to alleviate worry about what you want to do in kitchen.....And besides, you notice the different hardwoods as it is.....but a pro may be able to do something. You need to get a plan, and then plan B.

I think that you could do either. If you yearn for a nicer flooring in your updated bathroom and you can deal with having yet another flooring, then change out the bathroom floor with the update. Depending on your vanity choice you MAY have to do that if there is no flooring under the current vanity, anyways.

Then save for the whole-floor redo. You may be able to get away with a refinishing of the existing wood if it is the same species and you are happy to have that species in the rooms that now have vinyl, too. Strip the two wood floors, put in unfinished wood in the new areas, and have it all stained and finished in place. Even if there is a small difference in the appearance of the wood in the two older rooms, it is better than having all those different floors, and they will be a similar (if not same) color and finish.

I don't think bathroom flooring needs to be the same as flooring in other areas as it is generally different in most homes. I have wood floors everywhere except the bathrooms.

If I were remodeling your bathroom, I would not worry about current flooring in the kitchen or hallway but just put in flooring that works with whatever you are doing in that bathroom.

You can then tie in the kitchen/hallway areas to the others areas of the house when you tackle those. I do agree that you could probably get a good refinisher to get a stain so that the different wood floors are less glaringly different or one area of different wood might be a relatively small area and you might be able to replace just that area with wood that matches the larger area - whichever is more cost effective and provides you with a reasonable aesthetic result.
