We’ve had ours for nigh unto 17 years. Over the years I have only replaced a recirculation pump and a leaking heating element which were both fairly easy.

After about 10 years the LED lights quit working which we barely used anyway. We have a string of Christmas lights to provide illumination if we desire it. About 3 years ago it developed a leak somewhere internally beneath the insulating foam that would be near impossible to locate without destroying it utterly. As a result it needs topped off roughly once a week (on a well so water cost is negligible). We still use it 3-4 times a week and adjust the water temp to fit the season. Having a roof overtop is a definite plus for rainy/snowy nights. I have no regerts and will likely replace it when it finally goes irreversibly tits up.
