I am preparing to replace an old skirted tub, but I am little bit concerned about matching the the size of the new tub. Looking on lowes.com, I see a whole bunch of 30x60" tubs. The currently installed tub measures 28x58". I would think that the 30x60" inch tub is the correct size, but losing 2 inches on each side seems like a lot.

So all I am asking is whether 2 inches is typically lost in the apparent length of a tub after it is installed?

And while I am asking that, I would also like to know whether the position of the overflow and the drain holes in the tub are standardized.

Thanks for any help.

The usual nominal length is 60", width may vary by a few inches, but 30-32 is usual. Not sure the exact drain hole location is standard, that is why plumbing conections have slip joints.

A tub is measured from flange to flange. If you are measuring a tub that is currently installed and are measuring from the inside of the surround you won't get an accurate measurement.
