My shop phone rang on a Friday afternoon last summer — a couple stranded at a campground in Nevada because their bathroom sink had cracked clean through at the drain flange. Not a leak, not a drip, but an actual structural failure from years of vibration and one too many cabinet slams. The nearest RV dealer was ninety miles away, and they were supposed to leave for a week-long trip through Utah the next morning. We sourced a drop-in replacement, walked them through the swap over the phone, and they were rolling by noon the following day.
That call reminded me how little attention most RV owners pay to their sinks and faucets until something goes wrong. These are components that see daily use in an environment that's far more demanding than any residential bathroom — constant vibration, wild temperature swings, and water supplies that range from perfectly filtered municipal water to the sketchy stuff you pump from a campground well. The plastics crack, the faucet aerators clog with mineral deposits, and the chrome fittings corrode. All of it is preventable or easily fixed with the right parts.
The six products below cover the most common sink and faucet needs I see at RV Upgrade Store — from drop-in sink replacements in two sizes to faucet upgrades that make the bathroom actually enjoyable to use. Every one of these is a real-world solution to a real-world problem.
Best for: Class B van conversions, teardrop trailers, and compact rigs that rely on foot-pump or hand-pump water systems instead of a pressurized water pump
Before pressurized water pumps became standard in every RV, hand pumps like this Valterra Rocket were the primary way you got water at the sink. They're still the right solution for a specific category of owner — anyone with a simple, off-grid setup who wants reliable water delivery without the complexity of a pump, pressure switch, and accumulator tank. Pull the handle up and water comes out. Push it down and it stops. There's nothing to fail, nothing to prime, and nothing that needs a technician.
The chrome finish gives it a look that's clean enough for any interior, and the vertical pumping action is actually more ergonomic than it looks. I've had customers who converted old teardrop trailers and Airstream vintage units tell me the Rocket pump is exactly what the original build called for. It mounts through a standard sink hole and seals against the basin with a rubber gasket that lasts for years. For anyone building out a simple van or maintaining a vintage camper, this is a direct solution with no compromises.

Best for: Replacing cracked or damaged bathroom sinks in space-constrained RV bathrooms that require a compact drop-in basin
This is the sink I recommend when someone calls about a cracked basin or a unit that's delaminating at the seam. LaSalle Bristol makes purpose-built RV sinks from ABS plastic — not the thin thermoformed plastic used in budget sinks, but proper injection-molded construction that holds up to years of vibration without stress fractures. The compact dimensions make it the right fit for RV bathrooms where space is tight and the existing cutout is on the smaller side.
The drop-in design means installation is straightforward: lower it into the countertop cutout, apply a bead of silicone around the flange, set it in place, and connect the drain. The white finish is bright enough to make a small bathroom feel clean and open.
I've put these sinks in travel trailers, fifth wheels, and Class A motorhomes, and the consistent feedback is that they look better than what came from the factory. The high-gloss finish resists staining and wipes down easily — important in a bathroom that gets used every day on the road.

Best for: Standard bathroom sink replacement in mid-size to large RVs where full-size basin dimensions are required
The 16-by-20-inch version of the LaSalle Bristol sink is the one I stock most often because it fits the majority of RV bathroom cutouts in travel trailers and fifth wheels built in the last twenty years. The larger basin makes a genuine difference in daily use — you can actually rinse your face properly or fill a small bucket for cleaning without water splashing onto the counter. It sounds trivial until you've spent two weeks living in an RV with a sink the size of a salad bowl.
The construction is the same quality ABS plastic as the compact version, with the same drop-in installation. I installed one of these for a full-time RVing couple who had been limping along with a sink that had a hairline crack running from the drain to the front edge. Water was wicking under the countertop laminate every time they used the bathroom, slowly destroying the substrate. After the replacement, they told me the new sink felt noticeably more substantial than the original. The gloss white finish holds up well in humid bathroom conditions and doesn't yellow or dull the way lower-quality plastics do.

Best for: Replacing clogged or failed aerators on RV faucets and adding swivel flexibility to fixed-spout faucets
If you've ever turned on an RV faucet and gotten a spray that went sideways instead of straight down, or barely a trickle where there used to be decent pressure, a clogged or broken aerator is almost certainly the cause.
Aerators are the small screen assemblies that screw onto the tip of the faucet spout, and they collect mineral deposits from hard water at a rate that surprises most owners. In some parts of the country — particularly the Desert Southwest and rural well water areas — you can clog an aerator in a single camping season.
What sets the Phoenix Swivel Aerator apart is the swivel head that lets you redirect the water flow slightly without repositioning your hands. In a tight RV bathroom where the faucet is close to the basin wall, being able to aim the flow is legitimately useful. It threads onto standard faucet spouts and seals with a rubber washer.
I keep several of these in my service van because they're one of those parts you replace on nearly every sink service call. A customer at a campground once told me replacing this two-dollar part made his bathroom faucet better than the one he had at home. That's the kind of upgrade that earns its keep.

Best for: Replacing failing diverter faucets in RV tub/shower combinations where the diverter valve no longer properly switches between tub spout and showerhead
The diverter faucet in an RV tub-shower combination is one of those components that gets used hundreds of times a season and receives almost no maintenance attention. The internal rubber seals that control which path water takes — tub spout or showerhead — wear down gradually until the diverter stops holding position. You go to take a shower and water still pours out the tub spout. Or you try to fill the tub and the showerhead drips the entire time. Neither is acceptable on a rig you're living in.
The Phoenix chrome diverter faucet is a direct replacement that installs in the standard three-hole configuration used in virtually all RV tub/shower combinations. The chrome finish is more resistant to the constant moisture and humidity in an RV bathroom than the nickel or bronze finishes that look nice in showrooms but corrode prematurely in enclosed spaces with poor ventilation.
The diverter mechanism in this unit is robust and holds position firmly — when you push it up to direct water to the showerhead, it stays there until you deliberately push it back down. I've installed dozens of these and have never had a callback on a leaking diverter.

Best for: Upgrading the kitchen faucet in fifth wheels and larger travel trailers where cooking and food prep demands a high-arc, full-function faucet
Most factory RV kitchen faucets are the bare minimum — low-arc spouts with limited clearance that make filling a pasta pot or rinsing a large colander a frustrating exercise in cup-by-cup transfers. The Valterra Catalina changes that entirely. The high-arc spout gives you real clearance above the sink basin, and the two-handle design lets you dial in the exact temperature you want instead of fighting a single-handle mixer that's either too hot or too cold before it settles.
The brushed nickel finish is the right choice for an RV kitchen because it hides fingerprints and water spots far better than polished chrome — important in a kitchen that gets used constantly on the road. A friend of mine who full-times in a 42-foot fifth wheel replaced his factory faucet with the Catalina two years ago and told me it was the single upgrade that made cooking in the RV feel like cooking at home. The pot filler height means he can slide a stockpot directly under the spout and fill it without the awkward tilting maneuver that every low-arc faucet forces on you. Installation follows standard two-handle faucet procedure and fits most RV kitchen sink configurations.

Measuring your existing sink cutout before ordering a replacement is non-negotiable. Drop-in sinks are defined by the outside dimensions of the basin and the size of the hole in the countertop — these don't always match what you'd guess from looking at the sink surface. Measure the cutout opening from the inside, not the basin rim. Then compare that measurement to the product specifications. Most RV manufacturers don't publish sink dimensions, so you're measuring what you have and finding the closest match.
Faucet replacement is usually more straightforward because RV sinks use standard hole patterns — a single center hole for single-handle faucets, or three holes in a four-inch spread for two-handle configurations. If your current faucet is single-handle and you want to upgrade to the two-handle Catalina, you'll need a sink with the three-hole pattern or a countertop that can be modified.
For aerator replacement, simply unscrew the old aerator from the faucet tip counterclockwise — a pair of pliers with tape on the jaws to protect the chrome finish is all you need. The new aerator threads on clockwise. If mineral deposits have seized the old aerator in place, a few minutes soaking in white vinegar usually breaks it free without damaging the faucet threads.
Sink and faucet upgrades are among the easiest improvements you can make to an RV bathroom or kitchen, and the quality-of-life difference is immediate. A properly sized drop-in sink that doesn't crack under vibration, a faucet with a real aerator that directs water where you want it, a shower diverter that actually holds position — these are the details that separate a rig that feels functional from one that feels refined.
Whether you're dealing with a cracked basin, a calcified aerator, a failing shower diverter, or just a kitchen faucet that was never up to the task of daily cooking, every product in this roundup solves a specific, common problem. Stock the aerators and pump parts in your onboard kit — they're small, light, and inexpensive insurance against a plumbing headache at exactly the wrong moment.
