It depends on the tub. Tubs hold anywhere from 35 to 50 gallons or so.
Dimitri
Why go the average? Just calculate it yourself:
1) turn off all water-using appliances, and tell family to not use any water
for the moment.
2) Read the meter.
3) Fill tub to your liking
4) Reread the meter.
5) Do the math
Done!
-Tim
I may be wrong but don't most water meters read in 100 gal. intervals?

A simpler method would be to close the drain, fill and pour a 5 gallon
bucket until the water is 1" deep. Then measure the depth of the tub and
multiply to arrive at a total.

"Simply"???? There's the problem. The bottom is rounded and the sides
taper, the corners are rounded. (That's why the "measure one inch"
method proposed by another poster won't work, either.) The water
meter may be a little rough for these snmall qtys.
"Easiest" way would be to pour in buckets (my 4-gal household bucket
has incremental marks), *IF* he has the tub already. Otherwise, ask
the mfg regarding a specific model.
But if he just wants to know *about* what the *usual* is for planning
purposes, that has already been answered. He did SAY "average", not
"exact" or "specific".
-v.
Relax. There is no problem.
I figured that anyone who has an IQ of at least room temperature could do
the "simple" math in order to figure the number of gallons. But then, the
person did ask for the "average", and for that, one would have to take the
measurements for several tubs, add them together, and divide by the number
of bathtubs, wouldn't they. And then, there is the mean and the median.
I guarantee you that curves, and all, with that formula, one could hit it
pretty close. And I believe close is what the original poster was interested
in, now wasn't it? And after all, no one really did write in with the true
mathematical formula for determining an "average", did they?
Some people seem to have problems with simple math.
For the math impaired, the anally retentive and the perfectionist among you,
fill the d*** tub five gallons at a time with a bucket. Make little tally
marks on the wall so you won't lose count. This will allow for all possible
shapes and variances.

The way I'd do it is using calculus. But if that's too tough, you can
make a drawing showing the dimensions at the top and bottom and ignore
the curves (or measuring halfway up the curves). You'll get a fairly
accurate volume. If you use inches, divide your total cubic inches by
321 to get total gallons. I'd guess an average bathtub to be around
100 gallons, maybe more.

It depends on who is in the tub.
Eureka!

I hope so -- my water bill is based on it being so...
On the other hand, let's assume it isn't perfect. Could it possibly be
worse than timing a 5-gallon bucket then timing the fill and doing the math?
(makes lots of assumptions such as constant pressure...)
-Tim
OK, so you made me curious, so I tested it.
Read meter -- it said xxxxx3.5 gallons
Filled bucket to 5 gallon mark.
Read meter -- it said xxxxx8.5 gallons
So yes, it appears my meter is accurate.

I'm impressed. If memory serves me right, the water meters I am familiar
with were only accurate to within 100 gallons.

This won't work -- one tick on a meter is IIRC one hundred cubic feet, which
is a *lot* more than a bathtub holds. Using a water meter to measure the
capacity of a bathtub is like using a yardstick to measure the length of an
ant.

That doesn't work either. Bathtubs are wider at the top than at the bottom, so
each additional inch of depth represents a greater volume of water than the
previous inch.

Perhaps, but this is Usenet and as such it will be necessary to take into
account every possible nuance in the question, every possible solution to the
answer, backed with scientific notation and mathematical explanations
befitting a Nobel laureate and every possible method of flaming those who

It says 40-60 gallons for the average. This shows the absolutely terrible
shape of our education system in America, since the average of a 40 and 60
gallon tub would be 50 gallons. Makes me as irritated as when I see
professional signs that have been misspelled.
If you have too much time on your hands, you might do the same Google
search, and write down all the results. Then add them together, and divide
by the number of tubs measured. I am sure that the bathing needs of someone
say in Californicus is different than someone in South Virginia.
This will give you the AVERAGE.
HTH.

For what it's worth, I'm from Minnesota, home of water-meters in the
basement, and little remote readouts outdoors (connected to the main meter
via a wire which I assume works via some sort of dynamo or the like, as it's
not hooked to any power source).
Anyway, I did my reading off the main meter, which indeed has a fixed
ten-gallons digit, but has a dial which displays single and fractions of
gallons. You can read down to at least the quarter-gallon's place, maybe
more. I'm not sure how "precise" the outdoor remote is, and it's 0 degrees
out right now so I'm not going to find out any time soon <grin>

You are incorrect -- at least with my meter. Please see my reply to another

How much?
You'd "do it using calculus"? Hmmm.
I suspect that expressing a "typical" bathtub's exact shape as a
sufficiently simple, i.e., analytically integrable, [set of] vector
function(s), might be just a WEE bit of overkill and much more difficult
than either:
1. counting the number of 1, 2, 5 or whatever gallon, liter or whatever
buckets of water you have to dump into the tub until it's "full"
2. or, if 1. just isn't "mathematical" enough to satisfy analytical
cravings, treating the tub as a [set of] simple rectangular solid(s) for
which the volume (LxWxH) is easily calculable from simple measurements
and then, if desired, converting cubic inches, feet, cm or whatever to
gallons, liters or whatever.

What if it is a claw foot tub, and it doesn't have an overflow? How full
should I fill it to get an accurate measurement? When in a seated position,
would that be hip deep? Nipple deep? Neck deep? What about those whose
nipples ARE at hip level?
This is getting complicated. ;-)

Our's had a digital readout both inside and out!
Multipy these three measurements on your calculator.
Then divide the result by 231 and you automatically have gallons.
Whether fish tank, tub, whatever, it is a standard formula.

Looks like these things greatly vary by location. Ours definitely has a
digital readout on it - -just don't know how precise it is.

Why would my well have a water meter? It has a power meter.
Fill it full to the top? "Fill" it halfway? Just get enough water in
it to take a bath?

True. Hot water runs much faster than cold. Not sure if liquid
meters conpensate for that, but the gas meters do. Makes me wonder
if you get a better deal by purchasing gasoline on a cold day.
I'm pretty sure it's the same technology -- only instead of needing a
"reader" you just read the display.
FWIW: Every few years, the water company will come around and make sure the
inside and outside meters "match". They also do initial and final readings
this way when you move. That prevents people from disconnecting the wire
during sprinkling sessions, or other nasty tricks, from getting away with it
for very long.
-Tim
Obviously. I was assuming city water, which the vast majority of folks are
on.

It always helps to get the facts, and not to assume. From there,

with assumptions, it all goes out the window.
What "vast percentage" % of residences would you ASSUME have public water?
Notice I did not say city water because many people who get their water from
a pipe do not live within city limits. (my case) I just did a Google
search, and could not come up with the percentage, but perhaps someone with
more time or interest can find an accurate figure. The EPA figures I found
for per capita use was a 1990 figure .............. 183 gallons per day per
person. So, likely, any figure might be a decade (Pardon me, 12 2/12ths
years, for the nitpickers) old.
How many here are on wells?

Irrelavant. If you look at census data, the vast majority of folks live in
"urban" or "suburban" areas, all which would be served with a "pipe" as you
say. Are you really trying to question my assertion that more people get
water from a water company than a private well??
-Tim
No, not questioning your obvious assertion, which I would bet a day's pay is
true. Just trying to define "vast majority", and speak out about ASS-U-MING
things when doing home repairs.
Just trying to be more specific, as statistics can be gathered to support
any conclusion, and the use of proper terminology is important in
communication.
If in doubt, please reread my post.
Mine is very old and analog. The reading looks very much like a car's
odometer. I've also seen meters that had dials (like a gas meter). Y'all
must live in very new homes.

Good point. But unlike Steve would like me to believe, there's nothing

If you don't have a meter, feel free to ignore my original post.
My last reply to this branch of this topic...
-Tim
You're assuming again. :-)
In this case, the assumption is that living in an urban or suburban area means
that one is on city water. It ain't necessarily so.
I live in a metropolitan area of 1.5 million people (Indianapolis), well
within the city limits only about an eight-minute drive from downtown, and get
my water from a well. City water was not available in this neighborhood in
the mid-1950s when the homes were built; it's available *now*, but most of us
have not hooked up.
My in-laws live on the other side of Indianapolis; every home in their
neighborhood is on a private well.
This situation is much more common than you suppose.
I never use grout anymore. I use unpaintable white silicone.

But, certainly not rocket science, some judgement is almost always
necessary.
The formuls is always cubic inches divided by 231 .whether a cylinder,
oval, whatever.
I used it for 30+ years sizing hydraulic fluid reservoirs. It's in some
engineering books.
If you build minnow tanks for fishing, it's handy too!
Just a very handy easy formula, I hope it helps someone.
