Here are a few different things that will shift the cost dramatically: Size of the bathroom. The function of the bathroom. Materials and installation time. On average homeowners spend $10,000 for a bathroom remodel. On the high end, you could spend as much as $30,000-$40,000 and smaller budget-friendly projects might be closer to $2,500 or less. The estimated hourly labor rate for bathroom renovations is $50 to $75. More likely, labor costs account for 40% to 60% of the overall average cost of bathroom remodel. Meanwhile, the estimated cost for securing building permits is around $360 to $1,900. However, the price fluctuates on each state or city so it is best to consult your local.
