Designed for end-outlet drainage where the wall drain is closer to one side, this kit features an adjustable width between 11″ and 18″ and a flexible tailpiece hose that can act as either a P-trap or an S-trap.

Buying Guide: What To Consider When Choosing a Double Sink Drain Kit
Key questions to guide your decision:
- What sink spacing do you have? Some kits are tuned for 11″ to 18″ (or 15″ to 20″) center-to-center spacing, while others handle more variable layouts.
- What outlet configuration do you need? End outlet versus center outlet can materially affect fit and installation time.
- What materials and seals are included? Look for polypropylene or stainless components and reliable sealing washers to minimize leaks.
- How important is flexibility? If your cabinet space is tight or nonstandard, choose kits with flexible hoses or expandable tubes.
- Is this kit compatible with existing components? Ensure adapters and tailpieces match your current pipe sizes (1-1/2″ or 1-1/4″).
