Geez do you people have good marriages, or are you always ducking from your wife? Amazing.
My own opinion is that the hallway and bathroom are separate spaces, and nothing "needs" to match. You should use something that looks good in there.
As with any difference of opinion between married people, you have to a) decide how much of a battle it's worth, b) talk together about your individual feelings, and c) come to a consensus on what to do.
Simply saying "the wife is always right" is ridiculous, and not a sign of a healthy marriage. Similarly, to say "come on you wuss, show her who's boss of the house" would be equally unproductive.
Presumably you love this person and vice versa? Have you lost the ability to communicate? If you can't discuss feelings about a friggin' bathroom molding, how can you possibly discuss such imporant things as raising children, family finances, and staying faithful to each other?
If someone says "well I'd prefer it one way but I'll do what my wife wants because I love her and want to make her happy" that's one thing. But comments such as "Your wife is right . . . Otherwise you will never hear the end of it. The woman always wins in the end anyway." are just plain ridiculous. Why not just get a divorce if you hate your wife that much?
