View A01-2011VP productValterra RV Sink & Shower Drains: A01-2011VP vs A01-2012VP
Two RV drains can both lead to a 1½-inch P-trap without fitting the same opening in a sink or shower pan. Valterra's A01-2011VP sink-drain assembly includes a strainer basket and a small barbed connection, while A01-2012VP is a shower drain with a defined stainless-steel flange and shower-pan opening size. Match the drain opening and the plumbing underneath before choosing a replacement.

Where the measurements apply
Sink drain — A01-2011VP
This assembly includes a strainer basket and is designed to connect to a 1½-inch P-trap. Valterra also identifies a ⅜-inch barbed drain adapter. Those numbers describe downstream plumbing connections, not a confirmed sink-cutout diameter. Compare your existing drain body and sink opening rather than assuming the 1½-inch trap size is the hole size.
Shower drain — A01-2012VP
The shower-drain flange is 2½ inches in diameter and seats over a 1¾-inch drain opening. The lower connection is designed for a 1½-inch P-trap. Check both measurements: the visible flange covers a larger area than the opening through the shower pan.

View A01-2012VP productBefore replacing an RV drain
- Measure the actual drain opening, not only the outer trim or visible flange.
- Confirm the trap size and connection arrangement beneath the sink or shower.
- For the sink assembly, determine whether the ⅜-inch barbed connection is needed in your existing plumbing layout.
- Check the new drain can be sealed and secured to your particular sink or pan; follow the installation instructions for the plumbing components involved.
