Review Image by Mari Mari
Update: we installed it on Oct 22nd. I noticed it had a couple of tiny chips on the back before we installed it but you can only see them if you put your face on top of the backsplash, I didn't think it was worth the trouble. Now it's Nov 16 and it already has a chip right on the front. I wanted to change the vanity in the bathroom for 2 1/2 years, I was so happy to finally have a bathroom that I like and it didn't even last a month. Very frustrating to be honest. It's the sink we use the most but it's just two adults and one works 10h a day. Original review: We bought a new American Standard toilet in white, I build this custom vanity and then this was the third sink we tried. The first one was an Amazon Swiss Madison one that was not sitting flat, the second didn't fit the vanity without making changes to the back, and then we tried this one. There's not a lot of options with this measurements and it worked perfect. The only thing is that it does not match the toilet, it's a very bright white, but the vanity (in BM simply white) does match it and I think that makes it look OK. We got to keep our faucet, which we liked, and it's nice to have a backsplash already included. I was worried the bevel around the sink would make it look dated but in white I think it looks nice and works with the rest of the bathroom. ... show more

    • Received broken 5 times!
Color: White on White Size: 43 in. W x 22 in. D Pattern Name: Single Bowl
If you receive this product and it is not broken, buy yourself a lottery ticket! I know you are probably wondering why I reordered the product 4 times after receiving a broken item every time. I am trying to prepare myself for disappointment later in life, and thought that this would be an excellent way to do it. Boy did it work! I have lowered my expectations of ever having success or happiness at any point in the remaining years of my life. If anything good ever happens to me again, I will probably throw a week-long party to celebrate. I will then retire and be confident that the best years of my life are behind me. I know the price is low, but don't get stuck in the trap. The next thing you know, you will be 60 years old, prescribed to blood pressure medication and anti-depressants, and your bathroom sink will have been inoperable for about 10 years. Pay more for a quality product, avoid this one! ... show more

    • Very well made and packaged, but please note all the comments about the "white" color
Color: Solid White Size: 37 in. W x 19 in. D Pattern Name: Single Bowl
I read the reviews and was pretty sure I had picked the right vanity top. So many noted that the color was very bright white, that is what I was looking for. I had just redone my bathroom, put in bead board, painted it a bright white semi-gloss, new white toilet, and white with streaks of light gray floor tiles. When I put the vanity top in place, suddenly all the other whites in my bathroom became a grayish, way off-white, this vanity top did not blend in at all! it almost looked to be a pinkish white? Was so disappointed as the vanity top itself was very well made, great finish, no flaws at all, seemed very sturdy. Also, the top was very well protected by the packaging, if you order it and the box arrives intact, you can rest assured the item will be in perfect shape. What do I think about this vanity top? if your bathroom does not have white walls, the vanity is maybe a wood tone, then I think this top would work great. But, if you have many white things in your bathroom, especially a white vanity, this top is not going to blend, is going to make all your other white objects appear anything other than a bright white! Except for the color issue, I would highly recommend this vanity top! ... show more

had low expectations because... it's from Amazon. i tried to find one from lowes&home depot but couldn't find the size i needed. figured this could work until i figure out a better solution. BUT... this is legit! hoping the finish... lasts, but it's really well made. real stone, & super easy to install.i did this on a day i was home sick &not feeling well.. but was bored. had my old one removed&this one installed, faucet, plumbing.. everything in under a few hours. i should have gotten more of a "bone" color, instead of crisp white.. but, still looks good so no complaints. Will update in a year & report how well the seal/ finish holds up. but as of now, highly recommend. ... show more

    • BRIGHT WHITE
Review Image by Jana Jayyy Jana Jayyy
This sink fit my oddly shaped vanity perfectly. It came packaged well and I was able to install it myself ( 41 year old woman ). It developed a tiny hairline crack where the backsplash meets the base, due to me pulling it out of the box wrong ( my fault ), it was a lot heavier than I anticipated; but the crack can’t be seen so I installed it anyway. My toilet, tub, and moulding in my bathroom are all bright white, so I got this thinking it would match; but it’s actually whiter, a lot whiter. Though now that I have everything placed where it goes, and my bathroom remodel is complete, it actually blends in pretty well. You can’t beat this for the price. It seems very well built, and I’ve had it installed for a couple months with no scratches or dings so far. I keep it wiped down daily with a wet wash cloth. No complaints here. ... show more
