What This Bathtub Closure Fits

The Watco 58301-BZ lift-turn bath trap has a 1.625 in overall diameter with 16 threads per inch and a 1.25 in strainer body. It includes the Watco strainer body and lift-and-turn stopper in a bronze finish. The unit is new and carries a limited five-year warranty.

Installation Limits You Must Verify

You need to know the existing drain diameter and threads per inch before purchase because this closure only fits a 1.625 in opening with 16 threads. The flange measures 2.820 in, so the surrounding surface must accommodate that width. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals.

The Decisive Specification

The 1.625 in overall diameter combined with 16 threads per inch is the single measurement that determines whether this part will thread into your tub. If your current drain differs in either dimension, this closure will not install correctly.

Questions about this item

How do I know which Watco 58301-BZ version matches my tub drain?

Measure your existing drain's outer diameter and count its threads per inch; this closure fits a 1.625 in. diameter with 16 threads.

What does the 1.625 in. overall diameter mean once the part is installed?

It is the width of the stopper flange that sits inside the drain opening, so your tub's drain body must accept that exact size.

What does the 16-thread specification cap in practice?

It limits installation to drain bodies cut with 16 threads per inch; mismatched threading will prevent a watertight seal.
