6 Best Small RV Sinks For Tight Bathrooms That Feel Surprisingly Spacious

Trying to wash your hands in an RV bathroom can feel like a game of Twister, with your elbows hitting the wall and the shower curtain clinging to your back. The culprit is often a poorly chosen sink that devours precious counter and floor space. The right sink doesn’t just hold water; it fundamentally changes the perception and usability of a tiny bathroom, making it feel intentional and surprisingly open.

What to Look For in a Small RV Bathroom Sink

The material of your sink dictates its weight, durability, and maintenance. Most stock RV sinks are made from lightweight ABS plastic, which is cheap and effective but prone to staining and scratching over time. Upgrading to stainless steel gives you incredible durability and a clean, modern look, but it can be noisy and show water spots. Ceramic or glass vessel sinks offer a residential feel but add significant weight—a critical consideration for any RV.

Shape and mounting style are where you really win back space. A traditional drop-in oval sink is a safe bet, leaving a bit of counter on either side. However, a corner-mounted sink is the undisputed champion of space-saving, turning an awkward, unused corner into a fully functional washing station and freeing up valuable straight-run counter space. Vessel sinks, which sit on top of the counter, can also create an illusion of space and preserve under-counter storage, as they only require a small hole for the drain.

Don’t overlook the small details that have big consequences. A sink’s depth impacts splashing; a super shallow basin might look sleek but will send water everywhere. You must also match your sink to a compatible faucet. A large residential faucet will overpower a small sink and feel clumsy, so look for low-profile, single-handle models. Finally, double-check the drain size—many RVs use a smaller 1.25-inch drain, not the 1.5-inch standard found in houses.

RecPro 10" x 13" Oval Sink: A Classic Choice

This is the quintessential RV bathroom sink for a reason. Its compact oval shape is a direct replacement for the cheap, flimsy sinks found in many older campers. If your goal is a simple, effective upgrade without re-engineering your entire bathroom, this is your starting point.

Made from lightweight ABS plastic, the RecPro sink won’t add unnecessary pounds to your rig. This material is easy to clean with non-abrasive cleaners and holds up reasonably well to daily use. The main tradeoff is its susceptibility to scratches and potential for staining from harsh chemicals or hair dye. But for the price and ease of installation, it’s a pragmatic choice that gets the job done.

The design is its biggest strength. The gentle oval preserves more usable counter space in front and to the sides compared to a rectangular sink of the same capacity. It’s a no-nonsense solution that prioritizes function over high design, making it a reliable workhorse for weekend warriors and full-timers alike.

Vesuvio 15" x 15" Corner Sink: Maximize Space

When you absolutely must make the most of a shoebox-sized bathroom, a corner sink is a game-changer. The Vesuvio ceramic corner sink takes dead, unusable space and makes it the focal point of your bathroom. This single decision can free up enough counter space for toiletries or even just the mental breathing room that makes a space feel less claustrophobic.

The ceramic material is a significant upgrade from plastic. It feels solid, looks residential, and is exceptionally easy to clean and maintain. It won’t stain or scratch easily, giving your bathroom a touch of class that plastic just can’t match. The obvious tradeoff is weight. Ceramic is heavy, and you need to ensure your countertop and its supports can handle the load, especially on bumpy roads.

Installing a corner sink fundamentally alters the layout of your bathroom for the better. Suddenly, the main stretch of your vanity is open and clear. It’s the perfect solution for wet baths or extremely narrow bathrooms where a traditional sink would make the walkway impassable. This isn’t just a sink; it’s a strategic design choice.

SereneLife SLCARAVN20: Modern Glass Vessel Sink

A vessel sink is a bold statement in a small RV bathroom. By sitting on top of the counter rather than in it, the SereneLife glass sink creates a floating, airy look. The transparent tempered glass minimizes visual bulk, tricking the eye into seeing more space than is actually there.

This style has practical benefits beyond aesthetics. Since the sink isn’t recessed, you retain almost all of your under-counter storage space. The installation is also simpler, requiring only a single hole for the drain line. However, vessel sinks require a taller, specialized faucet, and you need to be mindful of splashing if the water pressure is too high for the basin’s shape.

Living with a glass sink means accepting a bit more maintenance. It will show water spots and toothpaste smudges more readily than an opaque material. A quick daily wipe-down is essential to keep it looking sharp. It’s a fantastic choice for those who want to inject a dose of modern style and are willing to trade a little practicality for a lot of visual impact.

Dometic VA 8005: Durable Stainless Steel Sink

For a sink that’s as tough as the rest of your rig, look no further than stainless steel. The Dometic VA 8005 is a compact, square, drop-in sink built for the realities of life on the road. It’s non-porous, hygienic, and can be scrubbed clean without fear of scratching or staining.

This sink is pure utility. Its simple, clean lines fit well in modern or industrial-style interiors. The stainless steel construction is lightweight yet incredibly durable, resisting corrosion and impacts far better than any plastic alternative. It’s the kind of sink you install once and never think about again.

The square shape is efficient, but it does occupy its corner of the counter more assertively than an oval sink. Some people also find stainless steel to be a bit loud when the water is running. But if your priority is longevity and bombproof functionality over delicate aesthetics, this Dometic sink is an excellent, long-term investment.

Lippert Flow Maxx: A Simple, Reliable Upgrade

Sometimes, the best solution is the one designed specifically for the job. Lippert is one of the largest component suppliers in the RV industry, and their Flow Maxx sink is engineered as a direct-fit replacement for countless factory-installed basins. This eliminates the guesswork of sizing and fitment.

Like the RecPro, this sink is made from durable, lightweight plastic, ensuring it won’t tax your cargo-carrying capacity. It’s designed to withstand the vibrations and temperature swings of RV travel. While it may not win any design awards, its value lies in its perfect compatibility and ease of installation. You won’t need to re-cut your countertop or reroute plumbing.

Think of the Flow Maxx as the "easy button" for a broken or hopelessly stained sink. It’s an affordable, practical fix that restores your bathroom’s functionality without turning into a major renovation project. For many RV owners, that simplicity is more valuable than any fancy material or design.

Elkay LVR1414C: Commercial-Grade Corner Sink

If you love the space-saving magic of a corner sink but demand maximum durability, the Elkay LVR1414C is your answer. This is a commercial-grade stainless steel sink designed for high-traffic environments, which makes it more than tough enough for an RV. It offers the same layout benefits as the Vesuvio ceramic sink but in a lighter, more rugged package.

This sink is built for function. The stainless steel is easy to sanitize, and the basin is often deeper than comparable ceramic models, which significantly reduces splashing. It’s the perfect choice for a full-timer, an overlander, or anyone who uses their rig hard and needs components that can keep up.

The look is undeniably industrial, which may not suit every RVer’s taste. But what you trade in residential warmth, you gain in pure, unadulterated performance. It won’t crack from road vibrations or chip if you drop something in it. For a bathroom built around utility and longevity, this Elkay sink is an unbeatable choice.

Installation Tips for a Leak-Free RV Sink

Your new sink is only as good as its installation. The first rule is to measure everything twice before you cut once. Check the sink’s rough-in dimensions against your available counter space, and confirm the location of the drain and faucet holes won’t interfere with anything below.

Sealing is non-negotiable. An RV is a box that experiences constant earthquakes, so your seals need to be flexible. Use a generous bead of high-quality, 100% silicone sealant or butyl tape under the lip of a drop-in sink to create a waterproof gasket. For the drain fitting, use plumber’s putty to ensure a watertight connection that can withstand vibrations.

Finally, pay close attention to the water lines. RV plumbing often uses PEX tubing, which requires specific fittings. Push-to-connect fittings are a great DIY-friendly option, but ensure the tubing is cut squarely and pushed in completely. A slow drip from a loose connection can go unnoticed and cause catastrophic rot in your RV’s floor and walls. Always pressurize the system and check for leaks before you call the job done.

Choosing a new sink for your RV bathroom is more than a simple replacement; it’s an opportunity to reclaim space and dramatically improve your daily life on the road. By prioritizing shape and material over sheer size, you can install a sink that not only works well but makes your entire bathroom feel more spacious and usable. It’s one of the smallest changes that can make the biggest difference.
