l guess it depends on the amount of use I guess . 70% it's just the two of us the other 30% 3 people . The tub is only 4 years old . I asked the checked with the tub store . They said it was no unusual with the amount of use .Wow. Mine loses less than an inch in 100 days. I do only open half the lid to slightly minimize evaporation when I use it. The only times it has gone down faster, I looked for leaks and found them each time. Tub is on interlock so a slow leak disappears without ever being visible from the outside.
