Several factors influence the cost and timeline of a construction project, including the project’s scope, materials used, and labor costs. For instance, using high-end materials or incorporating custom designs can increase expenses and extend timelines. Additionally, unforeseen issues, such as structural repairs or permit delays, can impact both cost and duration. In my experience, setting a realistic budget and timeline, while allowing for contingencies, is crucial. On average, a bathroom remodel can range from $10,000 to $25,000, depending on the complexity and materials chosen, with a timeline of 3 to 6 weeks.
