In Thornton, redoing a bathtub can cost anywhere from $300 to $1,500, depending on a variety of factors. If your bathtub requires refinishing or reglazing, that will likely run you between $350 and $600 for a typical tub. If you plan to do a full replacement of your bathtub, you can expect that project to cost between $1,000 and $3,000, including labor and materials. The principal things that affect the price you will pay for these services are the size and type of tub, any damage that might exist already, and your choice between refinishing and replacement. Generally, ceramic and porcelain tubs are less expensive to repair, while specialty materials like cast iron often incur higher repair prices.Thornton experts suggest homeowners solicit several estimates and closely evaluate the bathtub to select the most cost-effective and efficient repair method. Some homeowners choose to use a do-it-yourself refinishing kit, which can range between $50 and $100, but many local contractors offer free estimates that allow you to compare potential costs. Going the DIY route can save you several hundred dollars, but in my experience, the contractors who charge for labor get far superior and longer-lasting results.
