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.
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.

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.

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.

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.

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.

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.

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.

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.

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.

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!

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.

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.

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

- Availability Of 24" x 13" Kitchen Sink For 2018 Rockwood Mini Lite 2104SHello Geoff, thanks for reaching out. The closest thing we have to that would be the Better Bath RV Kitchen Sink # LC421572. This is 25" long x 15" wide overall. The interior of the sink is 22-7/8" x 12-7/8". Do you have any flexibility for the sink size? Would a 25"x15" fit?
view full answer... - How is the Better Bath RV Kitchen Sink 421572 MeasuredThe 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.

- Is There A Double Bowl RV Kitchen Sink That Fits 14-3/4" by 24-3/4" Cutout Hole ?Hey there Thomas. I have a solution for you, but we don't have a double-bowl sink that will fit your 24-3/4" x 14-3/4" cutout without modifying the countertop. The closest option that would work with your existing opening is the Better Bath RV Kitchen Single Bowl Sink # LC421572. It measures 25" x 15" overall and can be installed either as a drop-in or undermount sink, so it should be a good fit without needing to enlarge the opening. It's not a double bowl. If you'd prefer to keep a...
view full answer... - Looking For RV Kitchen Sink Or Countertop TrimHey 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.
view full answer... - Replacement Stainless Steel Sink for Forest River Salem 27RKHey Matthew! The Better Bath RV Kitchen Sink # LC421572 is the best replacement option for your Forest River Salem 27RK. This measures 25" long x 15" wide x 6-1/8" deep. 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. Any big trips planned this fall with your travel trailer?
view full answer... - How to Install the Better Bath RV Kitchen SinkDale, 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.
view full answer... - 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.
view full answer... - Do You Have a Stainless Kitchen Sink 25' x 17" with the Holes for the Faucet and Knobs?Well Howdy back Josh, We have something that will work for you, but none of them come with pre-drilled faucet holes, except for the double sink, which is much too large: # 34413TGS331974. If you're looking for a stainless steel option, the Better Bath RV Kitchen Sink - Single Bowl - 25" Long x 15" Wide - Stainless Steel # LC421572 is the closest we have to the 25" x 17" size. We do, however, carry the Better Bath RV Kitchen Sink - Single Bowl - 25" Long x 17" Wide - White # LC32ZR in the...
view full answer... - Looking For Double Bowl Kitchen Sink For 2007 Fleetwood BounderHello 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...
view full answer... - Recommended 25" Long x 15" Wide Stainless Sink Hey Bob. The Better Bath RV Kitchen Sink item # LC421572 is only available in a 6" deep for the 25" long x 15" wide model. The lip is 1" thick so it makes the overall height right at 7". You can pick up a flexible fitting at a hardware store if you're worried about your plumbing being short. With the offset the center of the drain hole is 5" on the Better Bath RV Kitchen Sink item # LC421572. It has a 3-1/2" diameter. How big is the cutout for your current sink?

The inside of the sink measures 22-7/8 inches long by 12-7/8 inches wide and is 6 inches deep.
view full answer... - Will Better Bath Single Bowl RV Kitchen Sink # LC421572 Fit 24 x 14 Inch Hole Yes, the Better Bath Single Bowl RV Kitchen Sink # LC421572 referenced in your question will fit into a 24 inch x 14 inch opening. Its dimensions excluding the outer flange are 22-7/8 inches long, 12-7/8 inches wide, and 6 inches deep. With the outer flange it measures 25 inches long and 15 inches wide so while it is designed for an undermount application it should work well as a drop-in sink for your purpose. I have attached a short video review that you can check out as well.

- 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.
view full answer... - Can the Better Bath Single Bowl RV Kitchen Sink Be Installed As a Top MountThe Better Bath Single Bowl RV Kitchen Sink part # LC421572 can be installed as either an above-mount or an under-mount.

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!
