RV & tiny home-stainless-steel-sinks

One of those overlooked features that most people don’t give much thought to is the washbasin in an RV. Until something goes wrong with it or you realize your current RV sink isn’t adequate for your needs. If you are dissatisfied with yours, you may wonder if it is possible to replace your RV sink and what to look for in a high-quality replacement.

The good news is that replacing RV sinks can sometimes be fairly simple. However, some plumbing-specific details require careful attention. You need to ensure that the replacement RV sink you prefer is compatible with your home’s plumbing and kitchen countertops.

We’ll have to dig in our heels and examine what makes a good RV kitchen and bathroom sink, in addition to how to ensure that your replacement is compatible with your RV’s plumbing system if we’re going to be of real assistance in helping you find the best RV sink. A few important questions are the first step in doing this.

Introduction Of Basic Information And Types Of RV Kitchen And Bathroom Sinks

In an RV, you can install a typical residential sink. The key is measuring to make sure it will fit, even though residential sinks and RV sinks are functionally equivalent.

However, given that most RVs don’t have the same plumbing as residential homes, there may be variations in the fixtures. Be aware that you might need to buy adaptors to connect any residential institutions you use to your RV’s plumbing system.

Types of RV Sinks

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.


The cheapest RV kitchen sink drain available is 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 washbasin with one is within anyone’s means.

Fibreglass RV sinks

Since it is prone to cracking, fiberglass is undoubtedly out of date. Particularly if it isn’t properly winterized. Even so, some “Vintage” RVs still exist, and their owners prefer to maintain the quality of the original materials used in construction.

The size, shape, and dimensions of fiberglass sinks can be changed to fit the space available, so they are another choice when having a professional install a custom sink, even though it might significantly increase the overall cost.

Porcelain Ceramic RV sinks

Compared to RV kitchens, bathroom sinks are more frequently made of porcelain. It is more prevalent in things like Class A motorhomes and luxurious fifth-wheel trailers because it is more expensive than some of the other materials used in RV sinks.

Campervan sinks made of porcelain can chip and crack easily, particularly if something large is dropped into it. In an RV, a porcelain washbasin is frequently better mounted into a vanity or counter than onto a porcelain pedestal.

Acrylic-Resin RV Sinks

RV sinks made of acrylic typically cost more but tend to last longer than sinks made of plastic. Even better, acrylic RV sinks have been “Shatter Proof” engineered into them, giving you additional peace of mind for a relatively low price. In RV bathrooms rather than kitchens, acrylic sinks are more common. Although this is more of a matter of personal preference than a functional complaint, some people take issue with the aesthetic appearance of an acrylic washbasin.

RV Sinks in Stainless Steel

Most people consider stainless steel aesthetically pleasing, making it more prevalent in RV kitchens. Additionally, stainless steel RV sinks are frequently durable and well-suited for use in vehicles that travel on rough terrain. Additionally, stainless steel is known to be extremely bacterial-resistant, making it ideal for use in the kitchen and in RVs with smaller-than-average freshwater storage tanks.

Additionally, manufacturers frequently use it, so you should have no trouble finding a stainless steel RV sink that fits almost any requirement. Naturally, as with any high-quality fixture, RV stainless steel sinks also tend to cost more. A replacement washbasin made of stainless steel for an RV will provide the greatest overall value if you have the money to play with it.

Overview Of The Pros And Cons Of Different Types Of Sinks And Their Respective Usage Scenarios

Top-Mount, Drop-In, or Self-Rimming Washbasin

Kitchen sinks that are top-mount or drop-in are the most popular and are installed from above. The sink is inserted from above through a hole that is cut into the counter material using a template provided by the sink manufacturer. The rim carries all the weight of the washbasin. Next, silicone caulk is applied to the sink’s rim to seal it to the counter. These sinks are occasionally called rimmed or self-rimmed sinks because the sink edge creates a boundary.


  • Installation requires no specialized knowledge.
  • However, the majority of DIYers can create washbasin cutouts from materials like solid surfaces and laminate.
  • The total cost is quite low.


  • Because of the rim, you cannot sweep dirt and liquid from the counter directly into the washbasin.
  • The rim of the washbasin is an additional component that requires cleaning.
  • The visual separation between the washbasin and the rim is unpopular with some homeowners.

Undermount Sinks

In contrast to top-mount sinks, undermount sinks are attached to the counter’s underside using special clips.


  • With an undermount sink, you can use a sponge to wipe away water and food particles from the countertop. Cleanup is a breeze with these sinks because there is no rim to get in the way.
  • Many homeowners find smoother looks appealing.
  • Superior to overmount sinks in quality, undermount sinks are frequently more popular.


  • Even though dirt doesn’t accumulate on top, it will gather where the counter and washbasin meet, underneath the counter.
  • In general, undermount sinks cost more to purchase and install than overmount sinks.
  • The size of your sink may be restricted by undermounting.

Single-Basin Bowl Sink

The broad category of single-basin kitchen sinks can include both in-counter and farmhouse (apron) sinks. There is no divided basin on this kind of washbasin.


  • Large items like casseroles and cookie sheets can be washed in one large basin.
  • Single basins are ideal for large homes with many occupants and functional kitchens.
  • One basin is the best option if you prefer the appearance of an apron sink.


  • Single basin sinks do not have space for a drying area on the side, so be prepared to have one.
  • Due to their size and rigidity, single basins are less common.

Discussion On How To Choose A Sink That Suits One's Needs And


When selecting the ideal replacement washbasin for your RV, there are a few different factors to consider. Any one of these could prevent you from properly attaching the replacement washbasin to the RV’s onboard plumbing system or force you to make significant changes to the plumbing already in place.


Ensure the sink’s four dimensions overlap the countertop hole by at least half an inch and up to an inch or more. When replacing an oval bathroom sink, things can get a little tricky.

Sinks & Fixtures

In addition to replacing the sink, most RV owners also choose to replace any outdated faucets and fixtures. If the Kitchen faucets and fixtures for your sink are not already included in the package, you must ensure that they, as well as the water lines and drains under the cabinet or vanity, are compatible with the sink before purchasing them.


Most RV sinks are referred to as “Over Mounted” sinks, which means that they are held in place by the countertop or vanity. While some “Under Mounted” RV sinks provide a greater depth in the basin. If you plan to handle the installation yourself, an over-mounted or ‘Drop-In’ sink should be your top priority.

The aesthetics of an under-mount RV sink tend to be better if you are particularly skilled or handy or if you are simply willing to pay a little bit more for installation.

The Material

Stainless steel, acrylic, plastic, and even fiberglass can be used to make RV sinks. Consider the various advantages and disadvantages of each.


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

Tips And Advice On Sink Installation And Maintenance

Let’s be honest about it. Many RVs don’t come fully equipped the way we want them. Not that you can’t still make changes on your own, however. The kitchen is frequently one of the first rooms in our homes to receive changes.

There is really no excuse for not having the kitchen you’ve always wanted, given the availability of replacement RV sinks in both quantity and quality today. They can be found at affordable prices, and in almost any shape, size, or color you can think of. They are typically easy to upgrade on your own.

  • Inspect the cabinets beneath your sinks every so often to check for any areas with moisture or dripping. If so, you may be harming both the cabinet and the items inside of it. Then there are the water lines for your water heater and washing machine. In addition, many houses have hose bib leaks outside.
  • When someone turns off a tap, have you ever heard a banging or slamming sound in your water pipes? This noise, known as a “water hammer,” is brought on by sudden changes in the water flow and pressure surges that cause the pipes to vibrate. Reduce water hammers by securing pipes to stop movement and lessen abrupt pressure changes. Many devices can be used to lessen the sudden changes in water pressure.

Exploration Of Sink Upgrades, Such As Replacing Sink Types Or Installing New Sinks

  • Depending on whether or not you have a sink that is an exact fit or whether you’ll need to cut out some of your countertop space, replacing your RV small sinkmay be a little more complicated. For the purposes of this article, we’ll assume that you don’t need to make any changes to the space.
  • Disconnect the water. Always begin by disengaging from city water and turning off your RV’s water pump. Open the lines’ pressure and prepare a bucket for any extra water.
  • Take out the sink hardware.
  • Old caulk around the sink should be removed. Cut through the existing caulking using a utility knife.
  • Connect the plumbing. One or two drain connections can be found underneath your washbasin. Cut the lines leading to the washbasin.
  • Connector brackets must be removed. The majority of RV sinks are fastened with connection brackets. Screw off the brackets.
  • Replace the washbasin by taking it out.
  • Activate the new washbasin. To install your new washbasin, adhere to the manufacturer’s instructions. Secure it first, then re-connect the plumbing. The sink can then be re-caulked, and the tap can be put back in.
  • Test the new washbasin by turning on the water and letting it drain after installation. Keep an eye out for leaks near the tap and sink drain.


Your RV’s kitchen or bathroom can benefit from a new washbasin, which can improve functionality and aesthetics. There are a lot of great options available, but size and compatibility are crucial considerations for RV kitchen sinks.
