RV & Marine Sinks, Sink Drains & Accessories
Whether you live full-time in your RV or spend weekends aboard your boat, the sink and drain system is one of the hardest-working plumbing components in your rig or vessel. Unlike residential plumbing, RV and marine sinks must withstand constant vibration, corrosive moisture environments, and the space constraints of compact living quarters — all while draining reliably every time. Choosing the right sink, drain assembly, and supporting accessories isn't just about aesthetics; it's about protecting your cabinetry from water damage, keeping your gray water system flowing freely, and ensuring your plumbing holds up mile after mile or voyage after voyage.
What's Included in This Category
This category covers everything from complete drop-in sink basins for RV kitchens and bathrooms to individual drain assemblies, strainer baskets, pop-up stoppers, tailpieces, gaskets, and mounting hardware. You'll find products sized for tight galley spaces, oval lavatory sinks for RV bathrooms, and heavy-duty stainless steel options built for demanding marine environments. Whether you're doing a full bathroom renovation or simply replacing a worn-out drain seal that's causing moisture problems under your sink cabinet, the right part is here.
Key Considerations When Shopping
- Material: Plastic sinks and drains are lightweight and resist corrosion, making them popular for RV applications. Stainless steel options offer superior durability and are preferred in marine galley environments where saltwater exposure is a concern.
- Dimensions: RV and marine sinks come in non-standard sizes. Always measure your cutout opening carefully — both length/width and drain hole diameter — before ordering a replacement sink or drain assembly.
- Drain Type: Pop-up drains, rubber stopper drains, strainer basket drains, and low-profile flush-mount drains all serve different purposes. Consider how you use your sink daily when selecting the right mechanism.
- Finish: Chrome, brushed stainless, white, biscuit, and parchment finishes are common. Matching your existing fixtures gives your space a cohesive, finished look.
- Included Hardware: Many drain assemblies include gaskets and mounting nuts, but confirm what's in the kit to avoid additional trips to the hardware store mid-project.
