Tips for Upgrading Your RV Sink in 2023

One of those undervalued amenities that most people take for granted is the sink in an RV. Up until a problem arises or you realize that your current RV sink is insufficient for your needs. If you’re not satisfied with yours, you might be wondering if you can replace it and what to look for in a high-quality replacement.

The good news is that replacing RV sinks can often be a simple process. However, there are some plumbing-related specifics that require attention.

What do I Need to Know Before Replacing an RV Kitchen Sink?

When selecting the ideal replacement sink for your RV, there are a few different factors to take into account.

Any one of these could prevent you from properly attaching the replacement sink to the RV’s onboard plumbing system or force you to make significant changes to the plumbing already in place.

1- Compatibility

This is possibly the most important consideration when looking for a replacement RV kitchen sink. Some RVs have unique infrastructure built into them that isn’t always compatible with aftermarket components.

2- Size

Make sure that the sink’s four dimensions overlap the countertop hole by at least half an inch and up to an inch or more. When it comes to swapping out an oval bathroom sink, things can get a little complicated.

3- Faucets & Fixtures

Instead of simply replacing the outdated fixtures, most people who replace their RV sinks also upgrade the faucets and other hardware.

Make sure that whatever fixtures you source will work with the sink, as well as the water lines and drains underneath the cabinet or vanity if your sink doesn’t come with faucets and fixtures already installed.

4- The Material

RV sinks can be made of fiberglass, acrylic, plastic, or even stainless steel. Each has unique benefits and drawbacks to take into account.

5- Mounting

The majority of RV sinks are what are referred to as “Over Mounted” sinks, meaning that they are installed into the hold in the countertop or vanity. Even so, some “Under Mounted” RV sinks have a deeper basin. An over-mounted or “Drop-In” sink should be your top choice if you plan to handle the installation yourself. An under-mount RV small sink is typically more aesthetically pleasing if you are skilled or particularly handy, or if you are simply willing to pay a little bit more for installation.

6- The Warranty Coverage

Although it is a minor factor, reading the fine print of the manufacturer’s warranty protection does help.

Some include language that states the warranty is void if the sink is not installed by a qualified professional or if it is installed in such a way that it later sustains damage.

What Are RV Kitchen Sinks Made Of?

In addition to size, there are many different kinds of RV sinks. The differences are mainly in the types of materials used, the degree of durability, and the aesthetics.

1- Plastic

The cheapest RV sinks available are made of plastic. Many entry-level RVs that don’t offer upgraded features come standard with them. Plastic sinks are affordable, lightweight, and simple to replace.

They also have a few shortcomings. RV sinks made of plastic are prone to cracking and staining over time. They also have fewer color options. But given their low price, replacing an old sink with one is within anyone’s means.

2- Acrylic

RV sinks made of acrylic are an improvement over plastic ones. They are less expensive and closely resemble solid surface sinks in appearance. Sinks made of acrylic are formed by heating them up and adding a fiberglass backing for support. They can be found in a wide range of colors and sizes, are less prone to chip or crack than plastic, and can withstand most spills.

Since acrylic is non-porous, mold and mildew cannot grow on it. There is no requirement for harsh chemicals or abrasive scrubbing. Your sink can remain shiny and new with just a quick wipe-down with soap and water.

3- Corian/Solid Surface

Corian is a well-known brand of solid-surface, non-porous material made from two-thirds natural minerals and one-third acrylic polymer. It is durable and has a high-end appearance. Although Corian and other solid-surface materials typically have a 10-year warranty, in actual use, they frequently last 30 years or longer. You might want to replace these kitchen sinks at some point due to scratches and burns or simply the desire to switch up your style.

4- Stainless Steel

Another excellent option without a high price tag is RV stainless steel sinks. They are present in a variety of sizes and shapes, and their prices are comparable to those of acrylic sinks. Since stainless steel sinks are similar to those found in homes, many RVers enjoy them. The ease of cleaning compared to other types of sinks is arguably the biggest benefit of having an RV stainless-steel sink. This is particularly true for a seamless sink, as it lacks any crevices or cracks where bacteria and other grime could conceal themselves.

When it is properly maintained, the RV stainless steel sink also keeps its appearance from the day it was installed. By gently buffing it with a soft cloth, it is possible to bring even a sink that has been abandoned back to almost-new condition.

5- Porcelain

Porcelain Sinks in RV bathrooms are more likely to be made of porcelain than those in RV kitchens. It is more common in things like Class A motorhomes and luxurious fifth-wheel trailers because it tends to cost more than some of the other RV sink components.

RV sinks made of porcelain are susceptible to chipping and cracking. Particularly if something substantial is thrown into it. Instead of placing a porcelain pedestal sink in an RV, it is frequently preferable to install it on a counter or bathroom vanity.

How Is an RV Sink Generally Mounted?

Sinks for RVs can be top- or under-mounted.


Through the top of the counter, a top-mounted RV sink is mounted. They are referred to as “drop-in sinks” at times.

Compared to an under-mounted sink, a top-mounted sink is less expensive and simpler to install. Because the lip of the sink completely encircles the edge of the countertop, they also frequently complement any style of countertop.

The disadvantage is that you can’t wipe anything from the counter into the sink directly because the sink’s lip overlaps the counter.


With an under-mounted RV sink, the sink’s body is positioned beneath the countertop, and its edge is positioned below the surface.

Because they are more expensive, under-mounted sinks should generally be installed by a professional. As a result of the need for a good seal between the sink and the countertop, under-mounted sinks are not as popular as top-mounted ones.

The potential for chipping the edge of the counter with heavy pots and pans is another drawback of an under-mounted sink when used in the kitchen.

However, since there isn’t an overlapping lip like in a top-mounted sink, under-mounting enables you to easily wipe anything on the counter (water, crumbs, etc.) into the sink.

How to Replace Sink Fixtures in Your Camper

It’s incredibly simple to upgrade and replace the sink fixtures in your RV. This particular upgrade has the potential to significantly alter how your rig feels and looks as there are many campervan sink ideas nowadays. Consider this as your next project if you want to give your RV kitchen a fresh look and feel.

Recommended Tools

Always gather your tools and materials before beginning a project.

In addition to the new faucet, you will also require a headlamp, a few adjustable wrenches, thread tape, some rags, and a bucket. You’re prepared to start this project once you’ve gathered your necessary tools.


Step 1. Remove the Old Faucet

You must first empty the area under your sink and shut off the water supply. Water can be turned off in two ways: either by closing the shut-off valves under the sink or by turning off the water supply from the RV park to your RV.

Step 2. Sink and Faucet Preparation

Since the old faucet has been removed, you will need to sanitize and prepare the sink, plumbing lines, and fittings for the new faucet. Make sure the sink is free of any silicon or plumber’s putty by cleaning it. Now, tape Teflon and pipe dope to every thread on the new faucet.

Step 3. Installing the New Faucet

The faucet can now be installed after all the preparation work has been completed. Crawl back under the sink after setting the faucet into the silicon or plumbers’ putty to firmly secure it to the sink. The kit’s nuts can be used to securely fasten the sink’s faucet to the sink. Now join the faucet’s plumbing lines.

Remove the sink aerator before turning on the faucet to ensure that it is not obstructed by foreign objects or installation materials.

Step 4. Checking for Leaks

Now that everything is wired up and under water pressure, it is time to check for leaks. Check all fittings and connections with your headlamp and a paper towel, wiping it to check for water.
