Best Answer: There's about 7.5 gallons per cubic foot. Filled to the top, a tub with those dimensions would be 12 cubic feet (2' x 4' x 1.5'). So, it would hold about 90 gallons. Of course you don't ever fill a bathtub to the brim and you have to leave room to get into the tub. So, it probably takes about 60 - 70 gallons to properly fill it for a bath. Source(s):
