Effective bathroom staging ideas include decluttering counters, using fresh white towels folded neatly, adding a small green plant, repainting the vanity in neutral tones, upgrading to warm light bulbs, using attractive soap dispensers, installing bright but soft lighting, adding a single scented candle, fixing any grout discoloration, keeping mirrors spotless, choosing neutral tile, removing personal items, and enhancing natural light. These simple ideas create a spa-like, welcoming atmosphere buyers appreciate.
