Bringing the luxuries of home out on the road is one of the most desirable aspects of traveling in an RV. You have your own bathroom, kitchen, bed, etc., anywhere you go. But few RVs come with everything exactly how you’d like. For many, this is especially true of the RV kitchen sink, which is frequently of lesser quality than a residential sink.

Luckily, upgrading an RV sink doesn’t have to be complicated. But you’ll want to understand what to look for in a replacement and what’s required for installation. We’re here to help, so let’s get started.

Upgrading Your RV Sink Is Easier Than You Think 

Most RV skinks are much easier to install than you might think. There are always exceptions, but the majority of sinks are over-mounted or drop-in sinks. These are the easiest to install.

There are also under-mount sinks, which make the sink flush with the countertop, creating a look of understated elegance. Under-mount sinks, however, are more difficult to install, often requiring a professional’s help.

What Size Are RV Sinks?

There’s no standard size for RV sinks. They come in many shapes and sizes, though most are rectangular. RV sinks start at about 9”x12”x5” deep and can be as large as about 14”x19”x8” per basin. Most also come with a standard 2 ⅛” drain hole.

The key to any RV sink replacement is to double and triple check the dimensions, including the depth, to be sure the new sink will fit in place of the old one. Also, consider the plumbing under the sink when checking for fit.

And don’t forget to consider the fixtures you’ll be installing so that the hole patterns match up. If you’re buying all-new fixtures as well, the sink and fixtures should match up.

Can You Put a Regular Sink in an RV?

Yes, you can put a regular residential sink in an RV. Residential sinks and RV sinks are functionally compatible, but the key is measuring to ensure it will fit. 

However, there can be a difference in fixtures, as residential homes have different plumbing than most RVs. If you’re using residential fixtures, know that you may need to purchase adaptors to connect them to your RV’s plumbing.

Types of RV Sinks

Aside from size, there are also numerous types of RV sinks. The variations come down to their materials, how durable they are, and how they look.


Plastic RV sinks are at the bottom end of the budget. They’re standard in many entry-level RVs that don’t offer upgraded features. Plastic sinks are lightweight, easy to replace, and are inexpensive.

They also have some drawbacks. Plastic RV sinks can crack and are more prone to staining over time. They also come in more limited colors. However, their low cost makes them an affordable way to swap out an existing sink on any budget.

A step up from plastic sinks are acrylic RV sinks. They’re less expensive and look very much like a solid surface sink. Acrylic sinks are heat molded into shape with a fiberglass backing for strength. They come in many colors and sizes, resist most stains, and are not as prone to chipping or cracking as plastic.

Stainless Steel

Stainless steel sinks are another great option without a hefty price tag. Like acrylic sinks, they come in many shapes and sizes, and range about the same in price. Many RVers like stainless steel, as they are reminiscent of residential sinks, are easy to clean and sanitize, don’t ding easily, and though they can get scratched, they are easy to polish. The biggest downside is the weight. 

Solid Surface

If you want the cream of the crop, solid surface sinks are your final destination. “Solid surface sinks are made from solid synthetic sheets formed by mixing a mineral compound with polyester and/or acrylic resins,” according to

Solid surface sinks can be nearly any shape, size, or color, and they can emulate high-end materials such as stone, granite, slate, and quartz. They are easy to clean, resist staining, and you can sand out scratches.

Solid surface sinks add a bit of luxury but come with a price to match. They’re at the top end of the spectrum in price and generally require professional installation, as well.
