Níveis

Cosmética (R$2.000-8.000): pintura, metais novos, espelho, acessórios. Média (R$8.000-25.000): gabinete novo, revestimento, box/banheira. Completa (R$25.000-60.000): tudo novo incluindo hidráulica. O banheiro tem o maior custo por m² da casa por causa da hidráulica, impermeabilização e revestimento.

Maior Impacto

A atualização mais subestimada: iluminação. Trocar plafon central por spots embutidos + arandelas ao lado do espelho melhora dramaticamente estética e funcionalidade. Custo: R$300-800 DIY. Impacto visual: como se tivesse gasto R$10.000.

⚡ CalcWolf Insight

A bathroom addition (adding a bathroom where one did not exist) recoups 53-58% of its cost at resale — lower than remodeling an existing bathroom. However, going from a 1-bath to a 2-bath home increases the buyer pool dramatically, making the home sell faster even if the dollar ROI is modest.
