3.5 or 3 online inch opening drain assembly with rubber stopper or basket strainer option chrome plated brass

Adaptability. Being able to shift and mold to fit different sinks
is what makes our Oswald Drain Kit an exciting addition to the
WatermarkFixtures lineup. Available only through
WatermarkFixtures, the Oswald online is a configurable drain kit;
fitting comfortably in a utility room, kitchen or bathroom. With
the ability to go from 3” to 3.5”, the Oswald can work in that
vintage laundry sink from your grandmother or in a stainless
steel drop-in sink from your local Lowes. For a more modern look,
drop in the included basket strainer, which restricts waterflow
with a single twist. If you're looking for a more vintage
aesthetic, the included rubber stopper will be the way to go.
Both the basket strainer and the rubber stopper are included in
the Oswald Drain Kit and can be switched out at any time.
Available in two distinct finishes, the Oswald can be purchased
in a classic polished chrome or an unlacquered brass. The
unlacquered brass is especially beautiful as it ages, developing
a rich patina with use.
