There’s a reason RV faucet upgrades often get pushed to the bottom of the list: they look like plumbing, and plumbing can feel intimidating. However, swapping out an RV faucet is one of the most approachable, hands-on upgrades you can make—especially when you know what to expect before you start. With a little preparation and the right parts on hand, this is a project that could really build your DIY confidence with relative ease.
In this guide, we’ll walk through the faucet replacement process step by step, from choosing a compatible product and prepping your workspace, to removing the old faucet and installing the new one. Whether you’re upgrading for function, comfort, or aesthetics, you’ll see that this is a manageable project that pays off every time you turn on the tap.
Shopping For the Right Replacement RV Faucet
RV water systems differ from residential setups. Space is tighter, access is limited, and components are designed to be lightweight and efficient rather than heavy-duty. That doesn’t necessarily make the job more difficult, but it does mean you’ll need to pay closer attention to details like faucet height, mounting style, and compatible fittings.
The good news is that modern RV faucets are designed with these constraints in mind, while still offering many of the same convenience features you’re used to at home, including single-handle operation, swivel spouts, pull-out sprayers, and modern finishes.
Before you buy, use the checklist below to make sure the faucet you choose is truly RV-friendly—and will install smoothly in your specific space.
- Match the mounting style and hole layout. Before removing anything, take a close look at your existing faucet from above and below the sink. Count the visible components on top (spout and handles) and, if possible, peek underneath the sink or vanity to confirm how many mounting holes are actually in use. Most RV faucets are single-hole or two-hole designs, but spacing can vary. Taking a quick photo under the sink can help you confirm what you’re working with and avoid buying a faucet that won’t line up once the old one is out.
- Check for clearance and reach. Look at what’s immediately around the sink—upper cabinets, window frames, and the depth of the backsplash or wall behind it. In tight kitchens or bathrooms, tall faucets or wide-swing spouts can bump into obstacles or feel awkward in use. Choosing a faucet with the right height and spout reach ensures it fits the space without getting in the way.
- Pick a finish that lasts—and that everyone can live with. Choose a durable finish that coordinates with nearby fixtures and hardware, especially in the close quarters of an RV interior. It’s a small detail, but picking something both you and your travel partner agree on can make the space feel intentionally updated rather than like a last-minute swap.
- Decide on features only if they actually help. Pull out sprayers, swivel spouts, or extra tall arcs are useful in some rigs, less so in others. If space is tight, a simple, compact design can be the smarter choice than adding extras you can’t fully use.
- Ensure it’s RV-friendly and considerate of water usage. RV water systems are built around limited onboard supply, so faucet efficiency matters. Many RV faucets are designed to flow at around 2.2 gallons per minute or less, often with built-in aerators that maintain pressure while using less water. Choosing a faucet specifically designed for RV use helps conserve water without compromising everyday usability.
Taking a few minutes to think through these details before you buy can save you time, frustration, and return trips later—setting you up for a smoother install once it’s time to get started.
Before You Start: Quick Prep Checklist
Before removing the old faucet, take a few minutes to confirm the basics. This small bit of prep can prevent mid-project headaches.
Do a quick recon:
- Clear out the cabinet or vanity under the sink
- Check how much access you actually have to fittings and mounting hardware
- Locate hot and cold shut-off valves (or know how to turn off the pump or city water supply before loosening any connections)
- Note any tight clearances, panels, or obstructions you’ll be working around
Gather your tools:
- Adjustable wrench or channel-lock pliers
- Screwdriver (Phillips or flathead, as needed)
- Pliers (for stubborn connections)
- Putty knife or plastic scraper (to remove old caulk)
- Rags or paper towels
- Small bucket or shallow pan (for leftover water)
- Flashlight or headlamp
Steps to Replace an RV Faucet
1. Removing the Old Faucet
With the water supply turned off, start by disconnecting the hot and cold supply lines under the sink. Note that even with the supply shut off, it’s normal for a small amount of residual water to drain from the lines, so keep a rag or shallow container handy. Next, loosen the mounting hardware that is securing the faucet to the sink or counter—this is typically accessed from below. Once free, lift the old faucet out from above and set it aside.
2. Cleaning & Prep Before Installation
Before installing anything new, clean the sink surface thoroughly. Remove old caulk, gasket material, or debris so the new faucet can sit flush and seal properly. This is also the time to dry-fit the new faucet. Set it in place without tightening to confirm hole alignment, clearance, and spout positioning.
3. Installing the New Faucet
Position the new faucet according to the manufacturer’s instructions, then secure it from below using the hardware provided. Reconnect the water supply lines, making sure connections are snug but not too tight. Exact steps and order can vary by faucet model, so always follow the directions included.
4. Final Checks & Testing
Once everything is connected, turn the water back on slowly and check for leaks at all connection points. Run both hot and cold water, test sprayers or swivel spouts through their full range of motion and confirm smooth operation. If anything drips or feels stiff, now’s the time for small adjustments.
