Before you remove, install, or replace any sink in your RV you need to read the production warranty to see if you’re allowed to do so.
Many companies have standard warranties that strictly prohibit you from installing any third-party add-ons or replacements without going through the official manufacturer.

Types of RV Sink Replacement & Upgrades
The term sink is very general and often times refers to any type of fixture that serves the primary purpose of providing and draining water.
There are several different types of sinks that come pre-installed with RVs and this section is going to help you figure out exactly what you can and cannot do with each sink fixture type.
Kitchen Sinks
The most common and probably familiar RV sink fixture type is the kitchen sink, kitchen sinks allow you to wash food before cooking it, clean dishes, wash your hands and a lot more.
Often times, people who replace or upgrade their kitchen sink do so because the existing configuration makes it difficult for them to operate.
There are a lot of custom-made kitchen sink add-on and after-market parts that you can purchase in order to give your RV that personalized feel that you deserve.
If you plan on replacing your RVs kitchen sink, consider contacting a local contractor who will be able to give you detailed information about the various options available to you.
Shower/Bathroom Sinks
Shower sinks and bathroom sinks are probably the second most commonly replaced or upgraded fixture type in RVs. Bathroom and shower sink fixtures can often times have very different dimensions and installation requirements which is why it’s important to confirm all of these critical aspects prior to requesting installation service or buying the upgrade.
You need to make sure that the shower/bathroom sink that you’re interested in is compatible with your specific RV model and build type. Bathroom and shower sink upgrades are a great way to add a sense of style in addition to maximizing the amount of space that’s available in your RV.
RV Sink Replacement & Upgrade Process
Once you’ve confirmed that you desired sink upgrade or replacement choice is compatible with your RV, and have read your manufacturer warranty in full, you can now begin the installation process.
Installing, replacing, or upgrading RV sinks can vary in difficulty depending on the type of RV that it is and what pre-existing infrastructure is built into the vehicle. Connection points and valve locations will also play a major role in the installation process of your new sinks.
While the process involved with replacing or upgrading your RV sinks will vary in difficulty, the same general steps and rules will typically always be used.
Before you begin, you may want to consider writing down the steps you took in order to disassemble the existing sink fixture. This can help you put it back together much easier due to the fact that all you’ll have to do is follow the disassembly steps in reverse.
Once you’ve got that covered, you need to turn off the water supply and hot/cold valves to empty out any excess water that may be residing in the fixture itself.
When you drain the hot and cold-water valves, you need to make sure that you label them so that you know which one goes where when you put it back together. Some RVs come with pre-colored hot and cold-water lines however you always want to confirm so that you can avoid any potential issues during the installation process.
Sinks may look simple but they use a very genius feat of ingenuity to conduct their function of water supply and drainage. One of the most important parts of any sink is the faucet, the faucet is where all of the water pours out of when you turn either the hot or cold-water knob.
If you plan on replacing your entire RV sink, you’ll need to remove the drain stopper which is connected to the faucet before doing so. Some RVs you plunger styles drain stoppers which are much easier to remove compared to traditional home-style drain stoppers.
Once that’s finished, you’ll need to move on to the couplers which are generally located underneath the sink at all corners of the fixture.
Simply unclamp or unscrew the couplers and your sink fixture should automatically lift up making it very easy to replace or upgrade. Clean the area where the previous sink fixture was installed so that you can ensure a tight and accurate fit for the new part.
Now it’s time to install your new RV sink fixture, one of the easiest ways to complete the job is by using plumbers putty. Plumbers putty is a specially formulated adhesive that many construction workers, repairmen, and many other people use to bind various materials like plastic, wood, metal, and more.
Place your new replacement sink on the pre-existing template that was left from the previously installed sink. Once your replacement sink placed on top of the existing framework, line up all of the couplers to ensure a secure fit once the installation is complete.
If you’re satisfied with its position, proceed to fasten the couplers in place so that you won’t have to worry about your new sink going anywhere.
After fastening your new sink replacement to the frame, you need to ensure that it is on an even level. An unlevel sink can potentially cause problems in terms of proper functionality for your entire system if not leveled evenly.
Now it’s time to reconnect the cold and hot water lines to your new sink installation, users can use thread tape or another adhesive bandage to secure the space between the water lines and the faucet connection. Always wrap your hot and cold water lines in a clockwise direction to make sure no water leaks out of the sides when in use.
By now, you should be able to simply open the cold and hot water valves to see if there are any leaks present before fully activating the water supply to the sink.
If everything seems to be working fine, then you can congratulate yourself on a job well done. If you notice any leaks in the hot/cold water valves, simply re-check the connection point to ensure that all passageways are tightly connected.
Types of RV Sink Options
When it comes to choosing the right RV sink replacement or upgrade for your vehicle, there are several different options to choose from.
