We replaced the toilet not long after we moved into the house, and splurged on a very nice Kohler Memoirs toilet.
Although I've gotten compliments on the 1960's era sink and lighted mirror, I think most homebuyers in this area would simply see them as dated and ugly. (This is not a hipsters sort of area.) They also do not have much storage.
The upside, though, is the massive amount of light the two flourescent tubes throw off.
The true eyesore of the bathroom, though, is the horrible bathtub surround. It wasn't installed straight, and so when we moved in, there was almost no functioning caulk around the bottom of the tub surround. In fact, the bottom edge was completely loose in a couple of places. I had to mega-caulk it with massive amounts of silicone caulk as a stop-gap measure. (Seriously. Like, two tubes of caulk.)
The surround was glued straight to the plaster walls, and it was glued with construction adhesive, not the colorless adhesive sold for gluing tub surrounds, so the glue shows through the plastic. It's also badly yellowed.
The faucet, handles and showerhead are the super-cheapest you can possibly buy, too. I am pretty sure any buyer would take one look at this tub and surround and leave the house immediately. I know I would, and I'm even pretty good at overlooking cosmetic flaws in a house. The caulk is a mess because it's spanning a much bigger gap than its designed to bridge, so it's not smooth and it doesn't drain water properly. It's also fully moldy now and impossible to get clean. Just gross.
Orange mold grows inside the hot water faucet and green mold grows inside the cold water faucet. Isn't that nice? No way to clean them except to take the faucet handles off. And who wants to do that every week?
One good thing: the tub is high quality enameled cast iron, and it's in fine shape. Other than being, you know, denim blue.
