extra long bathtub over 7'

years ago I did a ripout for the conversion of a mansion to a multi unit building. The ca 1890s master bath had an 8' cast iron claw foot tub. Apparently the original owner was quite large. The whole bathroom was marble. Sadly, the only way to get it out was to smash it. :(

You MIGHT try places that reclaim old fixtures, if your not worried about age I guess. Good luck!

    extra long bathtub over 7'

    does anyone know where to buy an extra long bathtub over 7 feet long so the inside dimension would exceed 5'6' long?

    also, if we have to find out how to build one ourselves, how do we calculate the volume of water in gallons 5'6' x 30' x 18' inside dimensions

    x long bathtub

    thanks, that's a decent amount of water.

    we were thinking about building a wood frame and fiberglassing it and adding tiles to lower the price versus pouring a whole lot of concrete on an upper floor of the house.
  • You going to have a body in there???

    The volume calcs are fairly simple. Break everything down to a common denominator (inches OR feet) and figure the cubes. There are 7.5 gallons per cubic foot. It is fair to assume that if the hot water is supplied at 140 degrees F, then roughly 80% of that fixed volume of water will be hot water.

    Only question that remains is the human bodies ability to displace water.

    I displace a LOT more water than my pretty, petite wife...

    Most of the 7 foot tubs I've seen are of the antique claws foot style. Make sure you have a code compliant facuet installed if you go that route. We don't need another outbreak of water bourne diseases from contaminated water back flowing form the tub into the water system...

    Might be just a tad pricey, but you would also be the only one on your block with one!

    No one answered the question

    The volume doesn't matter if you don't have the tub!!!

    And the copper tub link is NOT what was asked.
