RV Kitchen Sink Dimensional Diagram

Undermount Design

This sink has an undermount design. Undermount sinks install from below the counter and attach with the perimeter lip, which helps increase counter space. And because the lip is placed against the underside, it is incredibly easy to clean food and other debris from the counters without it getting caught in the lip. Undermount sinks are generally constructed from higher quality materials such as stainless steel, so they usually tend to last longer than drop-in sinks.


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, place it against the underside before securing it to the counter with the included mounting brackets. Once the sink has been installed, it is compatible with any faucet setup and standard 3-1/2" garbage disposals and drain baskets.

by:

Really nice sink which was easy to install, we can now get larger plates and dishes in this sink and we now don’t have the problem of the water coming from the faucet hitting the center divider and splashing everywhere like it did with the old double sink we took out.
Many thanks



by:

The sink was just what we were looking for. We hoped for more option in the stainless steel for this size. We replace the one in our bathroom. It started to rust in places. This is a great option. Fit perfectly.



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:

Looks Great after one year in outside fish cleaning station no warping or discolorations - cleaned a lot of fish and the sink cleans up well afterwards.



by:

This is a very nice quality sink. I only had to bend the right front corner down about 1” to for perfectly in my Allegro Red. First photo is after install.



by:

Forest River, for some reason, installed an over the top sink as an under countertop sink. It was so poorly constructed that a minor amount of weight had it drop out. This sink replaced the old and is installed properly, looks good and is easy to clean.



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:

I like everything about this sink, but I just installed it in my 2003 lazy daze motor home. First, I added pex 1/2x3/8” shut off valves to isolate the kitchen. Then trimmed the sink opening to 15”x23”for a snug fit to drill six 3/8” holes for the built in tie down studs in the sink rim. I installed the faucet first thru the sink opening( eBay $45, works well), then dropped the sink in and attached the anchors with #3 screws. The sink is very light and sturdy which is great in an rv, and the shipping was very fast. Hope the pics help.



by:

Amazing sink, needed this specific size for a laundry room sink and it worked out perfectly. Not only that but etrailer made sure it was delivered next day as promised and it was packed so well so it wouldn’t be damaged. Great buying experience and product.



by:

Very happy. I bought this same sink on Amazon first. It was packed like a kindergartner did it. Zero packing material and was all dented. This sink was packed very well. Paid a little more here, but it’s worth it so you get a sink in good shape.



by:

I renovated a 2008 Thor Chateau Sport 29R. The old sink was useless and had to go, it wasn't even 5" deep. I searched a long time and finally decided on the white Better Bath RV Kitchen Sink due to the precise measurements of the current stainless-steel sink. I removed the old sink and found that the opening in the counter was slightly smaller. I measured several times and determined what the opening should be. I was nervous but determined. It turned out to be the perfect fit. I really like the sink, it's classy and modern looking



by:

Sink was delivered without any dents or bent corners! We had to replace my undermount plastic double sink because the seal around the sink and counter let go and the counter material was lifting. The sink was also stained and splintered around drain on one side. I found this and fell in love with the large single sink. We removed the old sink and installed this as a top mount. I can't wait to use it! Love how it looks!



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:

Great quality, perfect fit, fast delive ry!



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:

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!



by:

This sink, even though an undermount one, worked well for a top mount as a replacement for the original double bowl plastic sink that came with our twenty year old 5th wheel. I pulled the old sink out and the single sink fit the cut out exactly, no trimming needed. The one part I was a bit uncomfortable with is there is no attachments due to it being an undermount style sink. I used a DAP style caulk on the underside of the perimeter lip and set the sink in place, effectively gluing it down. There is also no holes for a faucet so I had to cut a hole in the countertop behind the sink and install a new single mount faucet. While I was at it, I hole sawed in a soap dispenser. It works well in my application and I highly recommend it. The sink did arrived not very well packed and in an oversized box. This did allow the sink to move around and one of the corners was slightly bent but I was able to bend it back into place before installing it. This seems a common complaint regarding the shipping. The sink is slightly deeper than the orginal sink which caused me to have to do a bit of extra plumbing work to hook it up. Not a big problem though.



by:

Beautiful sink! Super easy installation. I’m overmount kinda gal so I love this a lot more than my last under mounted sink! Fast easy shipping is always a plus!



by:

I wish I had changed out my old white plastic sink in our RV for this one a long time ago. It fit into the opening looks great and much easier to do dishes in.



by:

Solid sink. Fast delivery.



by:

  • What Sink Best Fits a 25 3/8 x 14 1/2 Cut Out?
    Hi Gilbert, The Better Bath RV Kitchen Sink 27" long x 16" wide part # LC385313 will require modification to fit in your cutout. Because both the length and width of your opening are smaller than the # LC385313 you would need to cut into the counter to enlarge the opening for it to fit. You might have better luck with the Better Bath RV Kitchen Sink 25" long x 15" wide part # LC42UD. You would only need to widen the cutout instead of having to cut both ways and the length is only 3/8"...

  • What are the Bowl Dimensions of the Better Bath RV Kitchen Sink
    Hey John, so the actual bowl dimensions of the Better Bath Kitchen Sink part # LC42UD that you referenced is 23 inch by 13 inch as the flange around the entire sink is 1 inch wide.

  • Can The Better Bath RV Kitchen Sink # LC42UD Be Top-Mounted To The Coutertop
    The Better Bath RV Kitchen Sink # LC42UD is designed to be an undermount so it really wouldn't look the best as a top-mount. If you really wanted to you could just caulk the bottom of the lip of the sink to the countertop, but it's a pretty thin gauge without a bevel so it's not the best looking option. What are the dimensions of the cutout hole in the countertop? I might be able to find a top-mounted sink that could fit instead.

  • Can The Better Bath RV Kitchen Sink LC42UD Be Under Mounted To Granite
    Hello John, thanks for reaching out. Yes, the Better Bath RV Kitchen Sink # LC42UD can indeed be under mounted to granite. As long as you an adhesive that is suitable for stone, you will be good to go.

  • What Is The Difference Between Better Bath RV Kitchen Sinks LC42UD And LC421572
    Hello John, thanks for reaching out. The only difference between those two sinks is the # LC42UD is undermount only. The # LC421572 can be undermounted or dropped in. Aside from that they are the same 25" long x 15" wide x 6" deep, you just need to pick your preferred mounting style. Let me know if there is anything else I can do to help.

  • 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.

  • Can Better Bath RV Kitchen Sink LC42UD Replace Double Sink
    You can replace your double bowl sink with the single bowl Better Bath RV Kitchen Sink # LC42UD. As for fit, you need to ensure the measurements are correct. The # LC42UD measures 25" long x 15" wide x 6" deep overall, and has a 2" lip.

  • Additional Parts for Sink Installation
    The strainer that I recommend using with the Better Bath RV Kitchen Sink # LC42UD is the LaSalle Bristol RV Kitchen Sink Drain w/ Strainer Basket # 34439166. In addition to this you will need all of your pipes and connections as well as solvent like part # 3447530889. I've attached a link to our selection of plumbing pieces for you to check out, but I won't be able to tell you exactly what you need when it comes to pipes since each RV is different in design.

  • Could Better Bath UnderMount Kitchen Sink # LC42UD Fit 24 by 14 Sink Opening
    The Better Bath RV Kitchen Sink part # LC42UD would work for you. The flanges of it are 1 inch wider and longer than your opening and the bowl is 1 inch narrower and shorter so it would fit really well actually. It's normally an undermount but you could use it as a top mount.
