Yes. Most toilets offer the option to replace only the tank. Depending on the type of toilet, the tank itself can cost $30 to $200 or $100 to $250 for the tank and installation.
Many toilets last as long as 40 years, although homeowners often choose to replace them with more efficient models before then. Toilets are usually made of durable porcelain, so the fixture has a long lifespan. However, expect to replace the wax seal every 30 years to prevent leakage.
Under normal conditions, most toilet flappers last about four to five years. Heavy chemical usage can decrease their lifespan. If your flapper breaks after only a year or two, you may want to reconsider the chemicals you use.
On average, it takes a plumber between two and four hours to replace a toilet. It may take longer if your toilet is in a small bathroom or hard-to-reach place. Replacement times can also increase for more complicated toilet designs.
