Hi, it said that Maximum Fill - 43-1/2 Gallons. Thank you, Yanny/Luxvanity

Yes I see that - can it be set at 30 gallons?

Hi, The drain is already installed onto this unit. What do you mean by put the drain at 30 gallons? please be more specific.

With our septic we are only allowed to put a 30 gallon tub in - but were told if the manufacturer puts the overflow drain at 30 gallons we can install it

Hi, We cannot change the over flow drain on any of our tubs. They are made as is.
