  • RV Kitchen Sink Buying Guide: How to Choose the Best One

Recreational vehicles (RVs) are famous for travelers who enjoy the comfort of a home on the road. One of the essential components of an RV is the kitchen sink. Choosing the right kitchen sink for your RV is crucial, as it can make a significant difference in the functionality and efficiency of your RV kitchen.

This RV Kitchen Sink Buying Guide will examine the factors you should notice when selecting the best RV kitchen sink. We will cover different types of sinks, materials, sizes, and installation methods. At the end of this article, you will be equipped with the ability to make an informed decision when purchasing an RV kitchen sink

Types of RV Kitchen Sinks 

1. Top-Mount Sinks 

Top-mount sinks are installed by placing them on top of the countertop with their edges overlapping the countertop.


Easy to install, can be replaced without removing the countertop, and are generally more affordable than other RV kitchen sinks.


The overlapping edges can be difficult to clean, and the sink's weight can put extra stress on the countertop.

2. Under-Mount Sinks 

Under-mount sinks are installed under the countertop, with their edges attached to the bottom of the countertop.


The sink's edges are flush with the countertop, making them easier to clean, and they provide a sleek and modern look to your RV kitchen.


They are more difficult to install compared to top-mount sinks and replacing them may require removing the countertop.

3. Portable Sinks 

Portable sinks are freestanding and can be moved around as needed.


They can be used in different RV areas and are lightweight and easy to clean.


They take up countertop space and may be less durable than permanently installed RV kitchen sinks.

Materials Used for RV Kitchen Sinks 

1. Stainless Steel

  • Stainless steel sinks are durable, easy to clean, and withstand high temperatures.
  • Regular cleaning with soap and water, avoiding harsh chemicals that can scratch the surface.
  • Advantages: Affordable, lightweight, and can match most RV kitchen styles. 

2. Acrylic

  • Acrylic sinks are lightweight, come in different colors, and have a sleek look.
  • Regular cleaning with a mild soap and water, avoiding abrasive cleaners that can scratch the surface.
  • Advantages: Affordable, easy to install, and can add a pop of color to your RV kitchen. 

3. Composite

  • Composite sinks are made from a blend of materials, such as granite or quartz, and are durable and scratch resistant. 
  • Regular cleaning with soap and water, avoiding harsh chemicals that can damage the surface.
  • Advantages: Resistant to stains and scratches and can add a stylish touch to your RV kitchen. 

4. Cast Iron 

  • Cast iron sinks are durable and can withstand high temperatures and can come in different colors and styles.
  • Regular cleaning with soap and water, avoiding harsh abrasives that can scratch the surface.
  • Advantages: Can add a vintage look to your RV kitchen and are resistant to chipping and scratching. 

RV Kitchen Sink Features 

1. Size and Depth

  • Measure the size of your countertop to ensure that the sink fits properly and leaves enough room for other kitchen appliances and items. 
  • Consider the depth of the sink to accommodate larger pots and pans or to prevent splashing. 

2. Number of Basins

  • Consider your RV kitchen needs to determine the number of basins you require.
  • A single basin sink can provide more space for larger items, while double or triple basin sinks can provide more flexibility for washing and rinsing dishes. 

3. Faucet Holes

  • Determine the number of holes you need based on the type of faucet you plan to install. 
  • Some faucets require one hole, while others may require multiple holes for additional features such as a sprayer or soap dispenser. 

4. Sound Dampening

  • Look for sinks with sound-dampening technology to reduce noise while washing dishes or running the garbage disposal. 

5. Accessories

  • Consider additional accessories such as cutting boards, drying racks, and soap dispensers that can be installed with the sink to increase its functionality. 

Size and Dimensions

The size and dimensions of RV kitchen sinks can vary depending on the specific model and layout of the recreational vehicle. However, there are some common sizes and configurations that you'll typically find:

  1. Single Bowl Sink: Many RVs come equipped with a single bowl sink, which is generally smaller in size compared to sinks found in traditional homes. The dimensions of a single bowl RV sink can vary, but they typically range from around 15 to 25 inches in length, 10 to 15 inches in width, and 5 to 8 inches in depth.
  2. Double Bowl Sink: Some larger or more luxurious RVs may feature a double bowl sink, providing more versatility for kitchen tasks. The dimensions of a double bowl RV sink will depend on the size of each individual bowl, but they are typically similar to those of single bowl sinks, with each bowl being approximately half the width of the overall sink.
  3. Compact Design: Due to space constraints in RV kitchens, most sinks are designed to be compact and efficient. This means that even double bowl sinks in RVs tend to be smaller than their counterparts in residential kitchens.
  4. Folding or Collapsible Sinks: In some compact RVs or campers, you may find folding or collapsible sinks that can be expanded when needed for washing dishes and collapsed to save space when not in use. These sinks are designed to be lightweight and portable, making them ideal for small RV kitchens.
  5. Customization Options: Depending on the manufacturer and model, RV owners may have the option to customize the size and dimensions of their kitchen sink as part of the overall RV design or renovation process. This allows for greater flexibility to meet individual preferences and needs.

When selecting an RV kitchen sink or planning a kitchen renovation in an RV, it's important to consider the available space and how the sink dimensions will fit within the overall kitchen layout.

Installation of RV Kitchen Sinks 

1. Top-Mount Sinks 

  • Ensure that the countertop is level and has a cutout for the sink. 
  • Apply silicone sealant around the sink's edge before placing it on the countertop.
  • Secure the sink to the countertop with clips or brackets. 

2. Under-Mount Sinks 

  • Ensure that the countertop is level and has a cutout for the sink. 
  • Apply silicone sealant to the bottom of the countertop around the sink cutout.
  • Carefully lower the sink into the cutout and attach the sink's edge to the underside of the countertop with clips or brackets. 

3. Portable Sinks 

  • Place the sink on a level surface, such as a countertop or table. 
  • Connect the sink to a water source using a hose or tubing.
  • Ensure the drain hose is connected correctly and runs to a drainage system. 


In conclusion, choosing the right RV kitchen sink is essential for creating a functional and efficient kitchen space in your RV. Consider factors such as sink type, materials, features, and installation methods before deciding. With this guide, you should be equipped to make an informed choice and enjoy your new RV kitchen sink for years.
