Better Bath RV Kitchen Sink Dimensional Diagram

Drop-In or Undermount Design

This sink can mount as a drop in or as an undermount, so you are able to choose which setup works best for you and your RV. When used as a drop in (or self-rimming) sink, it's quick and easy to install into any countertop material. Once installed, because all parts of the sink are visible, you'll be able to thoroughly clean it in its entirety. When used as an undermount, it installs from below the counter with the perimeter lip, which helps increase counter space. It's also incredibly easy to clean food from the counters without it getting caught in the lip.


Better Bath RV Kitchen Sink Installation

If you're replacing your sink, you'll simply use the existing cut-out hole in your countertop. If you're upgrading your indoor or outdoor sink setup, you may need to enlarge the hole. It should be 3/4" smaller than the overall length and width of the sink. Either way, once you have a proper size hole, you can either drop it in or place it against the underside before securing it to the counter. Brackets and hardware are included. Once the sink has been installed, it is compatible with any faucet setup and standard 3-1/2" garbage disposals and drain baskets.

It looks great! Had it installed in my “new to me” 2015 Navion. This was the only place that had the correct size. If I were you I’d advertise it, the original double sink is not user friendly. Is there a cutting board that fits over it?

I wish we did but I haven't been able to find one. But that doesn't mean you couldn't get one somewhere else or possibly have one custom made. I hope you find one!



by:

Bought this sink to replace the under sink in our camper. It was poorly installed and was leaking which damaged the counter. This new top mount sink was a perfect replacement and eliminated the need to replace the counter. Also etrailer was great and helpful in getting me the right sink. Will definitely buy from etrailer if the need arises.



by:

I purchased this wonderfully adaptive sink a year ago to replace my double sink which came standard in my Tiffin motorhome. This is a perfect replacement on the allegro red 33 AA for anybody who may have the same model and be looking for a deep square single basin sink. I just washed the floor stuff. oh that’s OK



by:

It gorgeous I love it. The fit was perfect. I received it before it was scheduled, Made the upgrade in my RV just what I wanted.



by:

Arrived quickly and good quality



by:

The sink was purchased because I remodeled the kitchen in my Airstream. Replaced the old small double sink. Had it mounted under the corian countertop. The upgrade was perfect because the sink itself is made of top quality stainless steel. Etrailer price match along with free shipping



by:

Hard to find item...Etrailer had to order it, but they got it to me faster than they thought they could get it to me.



by:

Was very very pleased with the quality of the sink , nice solid sound and feel to it !
It was very well packaged and in perfect condition !!
Couldn't have asked for a better experience with E-trailer , ThankYou !!!!



by:

The item was delivered exactly as described, well packaged, and workd perfectly to replace our old Lippert double sink.



by:

Just what I expected



by:

I am a returning customer because my previous purchases have all been Excellent Service, Excellent Products and Fair Prices.
Among the "New" sinks selections were some listed as "Used", which are mostly New Scratch & Dent Items. There are photos and details of what is the issue with that particular item.
I selected and purchased a "Used" Sink for my RV Toy Hauler. It arrived quickly, was well packaged and was exactly as described and pictured. The price was very fair and well worth it.
My RV Toy Hauler is a brand new 2020 I just purchased. The first thing I did was remove the factory laminate counter tops and plastic sinks. Then logged on to etrailer to find Stainless Steel Sinks. The sinks arrived yesterday and I took them to the company making the new Corian solid surface countertops. They were very impressed with the product quality and then when I told them the cost they were really impressed. The counter tops will be ready for me to install in a few days. If it's possible to add photos to this, I will.

The Under Mount Stainless Sinks along with the new solid surface counter tops are a beautiful upgrade from the original OEM plastic sink and very basic countertops.



by:

Replaced the double sink my RV came with with this beauty. A nice big usable sink. Absolutely love it! Dropped right in with no problem. Wish I would have done it sooner!



by:

nice quality - thickness/gauge better than most - no 'tinny' feeling.
threads on one mounting post had some glop spill - had to get a metric tap to clean them up...



by:

Love it! Much better than the original double sink. Fit perfect and easy to install.



by:

This was a perfect fit, I had to watch my depth due to the water heater being under the sink as well as tying back into existing plumbing. I replaced the existing new split polycarbonate sink and the cheap quartz type countertop that originally cane with the RV. l installed new granite top with the SS sink. This one open style sink has been much better to wash in and allows ample room for what we needed.



by:

Properly packaged, fast delivery, excellent service, great price.



by:

This sink is a exact fit for Winnebago Navion's. If you don't like your shallow double sink in your view or navion this is the easiest replacement sink there is. No cutting of counter top just remove and replace with a little bit of plumbing modification.



by:

I searched for over a year for a single sink to replace the inadequate double sink from the manufacturer. This was a perfect match replacement in my 2018 Winnebago Sunstar. Even the old hardware was a exact match with the new sink. No cutting of pipes in my application was not needed either. I just simply repositioned the trap and capped the other drain pipe.



by:

Great fit !



by:

I searched the world over for a stainless sink to replace my tired and damaged plastic one. Several other vendors charged my card only to refund later because of a lack of inventory of the product they advertised. E Trailer has bailed me out a few times already. What a high caliber and professional operation!

The new sink looks great! I'm glad we had exactly what you needed. If you're ever needing anything else for your camper, let me know and I can make sure we have it available.



by:

This was a great replacement for my kitchen sink in my Coachmen Freedom Express 238BHS. The stock stick was a double basin sink so small that it was borderline useless. This thing is beautiful! It's square and my old one was rounded, so expect that and plan calk accordingly. The old mounting hardware worked, so I reused it.



by:

The sink looks great and fits perfectly. I wish I had purchased it sooner. The double sink in our vehicle was a challenge for larger dishes and pots.



by:

Hard to find size …fit perfectly in our Lakota C8315SRB
The shallow double basin sink it comes with was awful so happy to have this upgraded look!!!

The new sink looks awesome, Suzi! I can imagine the old one made it hard to really do anything other than clean a small cup or plate.



by:

We replaced the original under mount badly sealed sink in our 2022 TT.It was so bad it started to buckle the particle board counter top which we also replaced with laminate.
The drop in sink is much easier to seal.
Be careful with the threaded pems they are not to strong also check the threads with the wing nuts to make sure the will screw on.

Thanks for sending the photos! and now that you mention it, I think an undermounted style would give me a "sinking" feeling, too lol. Is it the install that makes you prefer overmount? The sink sure looks great!

  • How is the Better Bath RV Kitchen Sink 421572 Measured
    The overall dimensions of the Better Bath RV Kitchen Sink part # LC421572 including the lip are 25" long x 15" wide x 7" tall. The lip is 1" so if you wanted the bowl dimensions that would be 23" long x 13" wide x 7" deep. I have attached a photo for you as well.

  • Looking For RV Kitchen Sink Or Countertop Trim
    Hey Cameron, thanks for reaching out. Sadly, we do not offer any kind of kitchen sink or counter trim. All of the trimming we offer is like exterior trim for a camper or RV. We don't have anything meant for a countertop.

  • How to Install the Better Bath RV Kitchen Sink
    Dale, I spoke with Lippert and they said that the install instructions for both the top mount and underside mount are the same. So, I'm going to say that the studs can not be removed since they'd be needed for install. They were able to send me a copy of the instructions and it states that you're going to need to slip the L-brackets over the studs and lightly tighten the wingnuts. Once all of the wing nuts are on the studs, work in a clockwise rotation to tighten all of the nuts.

  • Replacement Stainless Steel Sink for Forest River Salem 27RK

Depending on your existing cutout you may have to enlarge the hole slightly for this to fit. The cutout should be 3/4" smaller than the overall length and width.

  • Recommended Kitchen Sink for a 14" x 24" Cutout
    Hey Marietta! The Better Bath RV Kitchen Sink item # LC32ZR in white or item # LC92ZR in gray are going to be the closest options we have to fit your cutout. They are top mounted sinks that have exterior measurements of 25" long x 17" wide x 6-7/8" tall so you'll want to make sure you have the extra width past your cutout. Interior will need a bit of widening to get the sink to drop in. They measure 22" long x 14-1/8" wide so you'll need to trim off an 1/8" of the width.

  • Looking For Double Bowl Kitchen Sink For 2007 Fleetwood Bounder
    Hello Dejay. I do have a good sink option for you, but the # LC421572 you mentioned is not good for a 15" x 26" cutout. There would be a 1" gap on the side of the sink, so the cutout would have to be modified. You say the original sink is a double bowl, so for that I recommend the Better Bath RV Kitchen Sink # LC388412. This measures 27" long and 16" wide overall, so it will fit nicely in a 26" x 15" cutout and it will cover the entire cutout. If you want to go with a single bowl, use...

  • Replacement RV Sink Options For A 13-3/8" x 24-1/2" Cutout Hole
    The closest double bowl option that we currently offer is the Better Bath RV Kitchen Sink - White # LC29FR. This sink is a top-mount drop-in design and would require a cutout hole 23.94" W x 16.44" L so you'd have to trim the cutout hole larger in order for it to fit. It also comes in gray # LC808488 and parchment # LC85ZR. We do offer a single bowl option, part # LC42UD, that's an undermount design and would have enough of a lip to mount in your 13-3/8" x 24-1/2" cutout hole.
