There is no definitive answer to this question as it depends on several factors, such as the quality of the kitchen, the level of maintenance, etc. In general, however, stoves would be around 10 to 15 years, depending on the brands and uses, before it needs major repair or replacement. The top-quality stoves would stay good for around 15 years without causing any trouble. Excess use of stoves can also reduce their shelf life. Of course, it can last much longer if you take good care of your kitchen and do regular maintenance. So if you're wondering how long your kitchen will last, it's important to keep these things in mind.
