A gold bathroom should feel like late-afternoon light pooling on tile — warm, a little vintage, never brassy. This palette leans on a burnished gold for the vanity, a muted ochre-gold that catches the light without shouting, the kind of color that feels aged rather than new.
Around it sits soft linen on the walls and a slightly cleaner warm chalk on the trim and ceiling, so the gold has space to glow instead of competing. The whites here lean warm on purpose — a cool white would make the gold look acidic.
Walnut brown grounds the room through the floor or a wood-framed mirror, and a single wall or alcove of deep olive gives the eye somewhere quiet to land. Keep that deepest green to one surface, no more than about one-fifth of the room, and the whole scheme stays soft and cocooning.
