Your RV sink and faucet probably aren’t something you give much thought to— until something goes wrong or you’re ready to replace the one you currently have. It serves a vital purpose in your rig and allows you to do basic things like get drinking water out of the tap, wash your hands, and clean your dishes. If you’re thinking about replacing and upgrading your RV sinks and faucets, we have all the info you need to know!

How it’s all connected

To better understand your RV sink, it’s important to know where it falls in your RV’s overall plumbing scheme. The water that comes through your faucet must come from somewhere and go somewhere after it flows down the drain. Here are the different parts of your RV water and plumbing system.

  • The freshwater tank and water hookup: Your RV freshwater tank or water hookup is what supplies the water that comes out of your faucets, shower, and toilet. 
  • The greywater and blackwater tank: Your greywater tank is where your used water from your sink faucet and shower ends up. The blackwater tank holds sewage from the toilet. In some cases, an RV will only have a black tank where all wastewater collects. One of the dirty— but necessary— jobs of RVing is dumping these tanks once they fill up.
  • Other parts of your water system: Your water heater, pump, and filter are each important components of your water system.

All of these work together to give your RV faucets a steady stream of fresh, clean water. 

Types of RV sinks

All sinks may serve the same function, but not all of them are created equal.

You’ll have a few main types of RV sinks to choose from:

  • solid surface sinks
  • copper sinks
  • stainless steel sinks
  • acrylic sinks
  • plastic sinks

Solid surface sinks

Solid surface sinks are becoming an increasingly popular option for RVers. These sinks, which often go by brand names such as Corian or Formica, are made from solid synthetic sheets that are created by mixing a mineral compound with acrylic or polyester resins. 

ProsCons
You’ll have a wide range of styles and colors to choose from.If you go with a cheaper solid surface option, it could be made with inferior materials such as calcium powder or cheap resins, which can make the sink look old and discolored quickly.
They’re durable, but if they happen to get scratched or scuffed due to long-term use, they can be sanded and polished to their original finish. Solid surface sinks are sensitive to high heat, so you’ll want to avoid putting hot pots and pans in there.
They can be seamlessly joined with solid surface countertops. This creates a sleek, modern look and also prevents the growth of mildew or mold around seams. If you want to join it with your countertops, you’ll need the help of a professional.

ProsCons
Copper sinks are durable and have a long life span.They’re expensive.
Some finishes (such as a hammered finish) conceal damage well.Copper may require more maintenance than other materials.

Stainless steel sinks

Stainless steel is a classic material that works with many decors. RVers love it because of its durability and reliability.

ProsCons

Acrylic sinks

Acrylic sinks are comprised of molded polycarbonate reinforced with fiberglass and resin. They are a popular choice for RVers because of their lightweight, easy installation, and low price point.

ProsCons
Acrylic sinks come in a variety of styles. Acrylic is fairly durable for light use but isn’t as long-lived as other options. It doesn’t hold up to heat well, and scratches and gouges fairly easily.
Minor scratches can be buffed out using a buffing compound. The polycarbonate doesn’t hold up well to petroleum-based chemicals.

Finding the best RV sink

Here’s what you need to think about when selecting a sink.

  • What kind of use is it going to see? First and foremost, you should consider how often your sink will be used and for what. If you’re a full-timer who loves cooking, you’re probably going to want to invest in a sink that can hold up to heavy use, such as stainless steel or copper. If you’re looking for a bathroom sink that will see occasional use, you can get by with a cheaper, less durable option.
  • What type of mount do you want? There are several sink installation types to choose from: drop-in, undermount, and farmhouse style sinks. Drop-in sinks fit into a hole and have a lip that hangs over the counter. Undermounted sinks are mounted from the underside of the countertop. Farmhouse-style sinks stick out from the counter, allowing you to see the front. 
  • What size do you need? Not all RV sink sizes are the same. Maybe you need a single, shallow bowl. Perhaps you want a deep double basin. Be sure to measure the dimensions of your current sink to see what fits.
  • How DIY do you want to get? If you want to do a simple sink swap, you’ll want to get a model that closely resembles what you currently have. If you’re comfortable taking on a bigger project, you can get one that is different. You will need to be prepared, however, to do a little extra carpentry/plumbing work.
  • Does it match your aesthetic? If style and aesthetics are important to you, you’ll want to consider how your sink fits in with the rest of your RV.

Knowing the answers to these questions can help you select the right material, style, and model that’s right for your RV.

Choosing the right RV faucet

If you purchased a new sink, you’re probably thinking of an RV faucet upgrade as well. Here’s what you need to know. 

Your RV faucet versus your home faucet

Good news— you can use pretty much any faucet you’d use at home in your RV. Though RV plumbing differs from residential setups, adapter kits make it possible to use the same faucets.

This means you have endless styles and finishes to choose from.

Things to consider

The main thing that you will want to consider when choosing the right sink is whether or not the connections will match up with what your RV is equipped with. Make sure all lines will be able to connect. If the sizes don’t match up, you will need to purchase an additional adapter.

You’ll also want to consider the number of holes that your RV has for the faucet and how many your sink has. If your sink has only one hole, be sure to get a corresponding faucet. If your sink has three holes, you can usually buy any type of faucet. Typically single-hole faucets come with a plate that covers up the two cutouts that aren’t used.

Buying options

A quick browse of any online retailer or home improvement store should give you plenty of buying options, but here are a couple of our favorites:

Replacing your RV sink and faucet

Many times, replacing your RV sink and faucet can be a DIY job. 

Replacing the faucet

Replacing the faucet is as easy as 1-2-3.

  1. Turn off the water. Aways start by turning off your RV water pump and disconnecting from city water, if you’re hooked up. Release pressure from the lines by opening up the faucets to help you stay dry while making the switch. It’s also a good idea to have a bucket handy to catch any water remaining in the lines. 
  2. Remove the old faucet. Under the sink, unscrew the connections using a wrench. Pull the faucet out and remove any old silicone or caulking using a putty knife.
  3. Install the new faucet. Insert the new hardware and secure it. Screw on any adapters, if necessary, and hook up the water connections. If you want, you can also reseal around the fixture with silicone and a caulk gun. 

After everything is installed, test the system by turning the water back on and opening up the faucet. Check leaks or dripping water. If you don’t see anything, you’re good to go! Installing a new sink faucet is a quick and easy way to breathe new life into your kitchen or bathroom.

If you come across a problem that you can’t fix, be sure to take your rig into an RV repair location or have a mobile repair service come out to you. Water damage can be costly!

Replacing the sink

Replacing your RV sink may be a little more complicated, depending on whether or not you have a sink that is an exact fit or if you’ll need to cut out some of your countertop space. For the purpose of this article, we’re going to assume that you don’t need to make any adjustments to the space.

  1. Turn off the water. Again, always start by turning off your RV water pump and disconnecting from city water. Release pressure from lines and have a bucket ready for excess water. 
  2. Remove sink fixtures. Follow the instructions from above.
  3. Remove old caulking around the sink. Using a utility knife, cut through the existing caulking. 
  4. Disconnect plumbing. Under your sink, you’ll find one or two drain connections. Disconnect those from the sink.
  5. Remove connection brackets. Most RV sinks are secured using connection brackets. Unscrew the brackets.
  6. Remove the sink, and replace it.
  7. Install the new sink. Follow manufacturer’s instructions to install your new sink. Start by fastening it, then reconnect the plumbing. After, you can re-caulk the sink and reinstall the faucet. 

After you install the new sink, test it by turning the water on and letting it drain. Watch for leaks around the faucet and sink drain. 

Keeping the fun and water running

A quality sink and faucet is just one way to make your RV both functional and attractive for your renters. Use these tips to spruce up your kitchen and bathroom to get your RV ready for the road today!
