How often should the water be changed in the tub?

Depends on bather load, water chemistry, etc.  The general consensus is every 3-4 months.  If you live in a colder climate like WI, you might go a little longer.  Changing the water in the dead of winter doesn't sound fun.

There is a formula that offers a rough guideline:

First, divide your total spa gallons by 3. Divide this result by your Bather Load, which is the average number of bathers per day. The final result is the estimated number of days between water changes recommended for a properly maintained spa or hot tub.


I think average usage ends up being around every 3 months.  I will tell you that most people probably do not drain their tub that often.  You can usually tell when it's passed time to drain.  Water quality will begin to suffer considerably as TDS (total dissolved solids) gets too high.

You'll know but there's nothing like fresh water.
