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.

Sink arrived quickly. One corner damaged and bent. We had thought about top mounting it, but the bent corner prevented that installation. Undermount it had to be. The brackets did not match up in size to the brackets for the old sink. Off to the hardware store to buy 6 brackets that are longer to hold the undermount installation. It’s a pretty sink. Disappointed the corner was bent. Considering there are no other options out there unless you have a custom size fabricated and spend three times the price. I’ll live with it.

Oh my goodness! I am sorry that it arrived damaged and was more difficult to install. I will have our Customer Service team reach out to you.



by:

Spent a lot of time looking for a sink to fit without much modification. A fellow member on the Forest River RV forums. A fellow RV had the same sink size as mine! Picked it up yesterday and it is a PERFECT fit! Can't wait to get it installed!

On the flip side, packaging was not that great. One big piece of paper? It was sliding side to side in the box! Better packing material would help avoid dents and dings in shipping!

Would not replace this sink. Perfect fit for my RV!



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.



by:

The sink arrived within the promised window, it looks great and the dimensions are true to the etrailer description. Installation was uneventful but I used the retaining clips from the prior sink as they were good sized pieces of steel instead of the aluminum ones that came with the sink.

I took off a star for the light guage of the sink as I'm concerned that it might scratch or dent farly easily if we're not careful. I took of another star because the corners are not radiused, they meet at a sharp 90 degree angle. Most of sink openings in rv's are radiused so the fit isn't perfect. I went ahead with the installation as my wife was not bothered by the way the corners look.

One odd thing about the sink is that the manufacturer included a strange automotive type hub cover



by:

Undercounter mount to quartz countertop. Much better than the double bowl that it replaced. It was bought as a scratch and dent one corner was bent,fixed with a pair of pliers, great buy thank you etrailer.



by:

I purchased this sink as a replacement for a two basin sink in the galley on my sailboat. It is such a big improvement! It was easy to install and fit the space perfectly.



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:

Fast shipment, great service. I haven’t installed the sink yet, or even unpacked it, so I can’t really comment on the purchased item itself.

Well, that is fine! I am glad you had a good experience. Whenever you get the chance, we would love to hear your thoughts on the product as well!



by:

Very sturdy box! Not enough packing. One dent. One scratch. The rim looks straight though so I guess I'll install it.

I see that there has been a reshipment of this item and am glad to see that it has arrived with no damage. Per our customer service department, they have reached out to the manufacturer for cut-out patterns and instructions, per your second request. Unfortunately, these sinks do not come with a cut out pattern.

August of 2022 I purchased a beautiful single basin kitchen sink for my classic 96 B0under class A motorhome. Well I can now tell you that it has been one of the most satisfying purchases Ive ever made. It continues to shine and resist denting and scratches. The single basin is such an improvement over the standard double basin sink that should I ever purchase another rv with a double basin I will immediately replace it with this beautiful single basin. Excellent product!



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:

Awesome sink to replace the cramped double bowel original in my Lakota Charger. This has so much more space. Great quality that looks like it will last the life of the trailer.

Sink came bent and dented really nice sink tho just needs to be packaged better

The sink is great, love it. But…it came a box too large with minimal packing and one end had the lip bent down over the side. I think we’ll be able to straighten it.

Hey I am glad that you like the sink however I am sorry that it arrived slightly damaged. I will have Customer Service reach out in case it was not able to be straightened.

Love it. So much better than those tiny double sinks, and it fit right in the same hole.



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 is an excellent product and the service received from etrailer was great with one exception. The packing of the sink was not adequate.

The sink was placed in an oversized box with only an empty box inside help make it fit slightly better. There was no other packing at all. The sink had room to slide around quite a bit and was damaged in 3 places during shipping.

Given that etrailer has other damaged sinks available for discounted sale, and other reviews nothing shipping damage, it would seem they should understand how easily these are damaged and pack them better. Some bubble wrap, packing peanuts or foam would do wonders.

I did install the damaged sink. I should note that this is the 3rd sink I have purchased (2 from other retailers) and each has had similar shipping damage. I basically gave up trying to get a new sink shipped without damage. I also contacted Lippert about the issue and it seems to be a common issue when reading the reviews of any retailers of this sink, including direct from Lippert. It's a shame because this is a really nice product, perfectly matched as a replacement and easy to install. Somebody just needs to figure out how to pack it for shipping.

I have purchased from etrailer before and found them to have very competitive prices, fast shipping and great service. In this case it was a disappointment.

I am sorry to hear that this arrived in this condition. I have gotten in contact with our vending manager and they are working on the shipping of this in the future. I also have sent your information over to our customer service department for them to get in contact with you about this damage.



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:

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:

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:

The quality of this sink exceeded my expectations and looks great in my trailer. It is so much better than the cheap plastic sink that the trailer came with. I would definitely recommend this sink.



by:

Easy to track, arrived on time, small dent in outer lip, but repairable.



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:

Excellent quality and arrived on time. Quality service.



by:

The sink was in a plastic bag put in an oversized box and insufficient packing to keep the sink from moving around in the box. The plastic bag was torn in several places which looked like it was repacked. The sink flange had 3 dents in it upon unpacking it. I will return the product for replacement. On a positive note I received the package in a timely matter and the box had no damage.

I will have our Customer Service team reach out to you.



by:

Our new stainless single bowl sink looks great! So much better than the old 2-bowl sinks. Plenty of room to work and makes the whole sink area look wide open. This is one of the last 'to do' items of our 1976 Prowler renovation.



by:

bought this for our RV it was the best thing we ever did!

I still think it was the best thing we did, I still love my sink. In fact a friend was just looking to change the sink in their RV and we recommended they check Etrailer.

  • What Hardware Is Needed To Install As Drop-In
    The Better Bath Single Bowl RV Kitchen Sink, # LC421572 can definitely be used as a drop-in mount. It is 25" long x 15" wide with tapered flanges that support the stainless steel sink upgrade being used as a drop in mount, installed using the same type of sink mounting clip hardware as a residential sink. The hardware will need to be sourced locally with specific type used dependent on thickness of your counter-top.

    The Better Bath Single Bowl RV Kitchen Sink part # LC421572 is designed to fit a rectangular opening of at least 13 1/8" by 23 1/8". If your opening matches this or is not more than 1 1/8" larger than that this would be a good fit. If your opening is smaller than that and can be enlarged to match these dimensions it will also work out for you. If the opening you have is larger than that you will want to choose a sink with a larger cutout requirement to match up.

  • Locating Replacement Single Bowl Sink for Lakota Charger

  • Is It Better To Go By Bowl or Flange Dimensions For Kitchen Undermount Sink
    For an undermount sink I recommend comparing the bowl interior dimensions as opposed to the flange exterior dimensions because you want to make sure the bowl matches up with your cutout. For example, the Better Bath RV Kitchen Sink # LC421572 will fit great as an undermount for a 22-7/8" long x 12-7/8" wide cutout, but you want to avoid using this as an above-mount if the cutout is a little smaller than 25" long x 15" wide because you need enough room for the flanges to still overlap...

  • 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.

  • Better Bath Single Bowl RV Kitchen Sink Compatibility And Parts Needed For Installation
    Yes, the Better Bath Single Bowl RV Kitchen Sink # LC421572 is going to fit your 14-1/2" x 24" opening. For a drop in installation you'll just need some silicone caulk to mount the sink to the counter. For the drain you'll want one that fits a 3-1/2" diameter like the Kitchen Sink Strainer w/ Push-In Basket for 3-1/2" to 4" Drain - Steel # 37295295, which will also require some plumbers putty for a watertight seal.

For a 16 inch wide sink we offer the Better Bath Single Bowl RV Kitchen Sink # LC385313. This sink is also 27 inches long and requires 6-7/8 inches of depth. I have added links to video reviews of both sinks for you to check out.

    The Better Bath Single Bowl RV Kitchen Sink - 25" Long x 15" Wide - Stainless Steel # LC421572 comes with the same mounting hardware you pointed out comes with sink # LC385313. I also recommend using the Loctite RTV 5699 High-Performance Silicone Gasket Maker - Grey - 2.7-Fl Oz Tube # LT37464 to seal the sink to the underside of the counter.

  • Needed Wire For Rewiring Electric Trailer Brake

This meets SAE J1128 specifications up to 50 volts and its insulation is rated to 105 degrees Celsius. This is sold per the foot.
