My concern with the Top Zero is the sharp edge profile. If you drop a cast iron skillet, you're not only getting a chip, you're getting a sink dent too. Replacement would probably be the only repair.

I wouldn't install an overmount sink in my kitchen but wouldn't that dent too if you dropped a skillet on the edge? Or why draw the line at the edge of the sink, if you drop a cast iron skillet in a stainless steel sink you're going to get a dent.

It's really hard to idiot proof everything. Where do you draw the line? There isn't much in a kitchen that is going to survive dropping a cast iron skillet on it unscathed.

It's the repairablilty factor. Stone by itself can be inconspicuously repaired; stainless somewhat, but not in the TopZero combination.

The problems I mentioned with the Top Zero are easily eliminated by simply shrinking the cutout a poo, profiling and polishing the edge with a 3/8" round over, then setting the sink into a rabbet just below the end of the edge profile.

Now the top edge is stone all the way around the sink corner edge and the adhesive joint between the side of the cutout and the sink is hidden. I'd be just like an integrated sink in Corian, but in stone and stainless steel.

Hi! @Joseph Corlett, LLC I am looking at doing dekton with a top zero. I am using the top dekton installer for my area so I have covered that base. I was advised by Roberto Colonetti to use a flushmount sink. Do you think the TopZero covers the bases and helps eliminate potential corner cracking and chipping? Or do you think the Mila sink does a better job (they are not zero edge- they are flushmount with a rim)- are the two equal in terms of TRYING to protect the stone from chips/cracks? Also, I was warned that both sink will have an epoxy used and that epoxy will yellow over time (my countertop is dekton rem so it will be color matched light). Do you find that an issue or how can that issue be overcome? Thank you!

I am hesitant to recommend anything contrary to Colonatti. That said, I'l love to know his reasoning. It's a risk to do any 90* inside corner in sintered in my opinion, but I can't see how a flushmount 90* corner is any different than a TZ 90* inside corner. If anything, the adhered TZ would provide more corner support than a flushmount.

If you're feeling lucky, I'd have the TZ mounted and finished in the shop along with any underlayment on the Dekton. If it makes it from the shop to your home without cracking, you should be fine.

Colonatti probably likes the sink edge profile protection the flushmount offers; the TZ kind of does the same. TZs come with a two-part methacrylate adhesive, not an epoxy, which won't yellow. If the sink is installed properly, the adhesive line should be very inconspicuous anyway.

Thank you! @Joseph Corlett, LLC Roberto liked the TZ- just wasn't familiar with it as I don't think they sell it where he is. He was comfortable with it for the same reasons you were- 90 degrees/rounded so you are completely on the same page. Thank you for your reassurance. It is an absolutely beautiful sink and I cant wait to see it with the dekton. My fabricator is giving a year warranty on cracks after install but I don't know about the feeling lucky during transport ;) So glad to hear the epoxy won't yellow. Much appreciated Joseph! You addressed all my concerns

Melanie:

The TZs are manufactured in Turkey and are some of the finest production sinks available. You won't be disappointed.

I started this thread and it's interesting to see how Joseph has come around on these sinks over the years. I've had two for a few years now, installed with quartz counters, and I still love them as much as the day I got them. I'm sure you'll love them too!

Thank you #uscpsycho

I ended up going with a MILA sink bc the TZ finish was sold out. Such a bummer bc I love the TZ zero edge. Glad to hear you are enjoying yours.

I'm wondering how or if the earthquake in Turkey has affected TZ.

Sink started cracking at the edge. Top zero came out to repair, tech refused to finish saying these cannot be installed in Corian and claimed it was incorrectly installed and that it was too soft, & the counter was too thin. he refused to touch it after starting one corner for fear of damaging out counters. We hoped he resolved the issue by putting in supports under the sink to help with vibration from the disposal. He claimed the disposal was causing it to come loose but they never gave us a real concrete straight answer as to why this was coming apart from the countertop.

Now sink is worse (see photos), it’s completely coming apart from the countertop around the perimeter of the entire sink. We asked for the owner Yavuz to meet with our countertop company at the same time to resolve for a permanent fix. It’s been weeks and will only send a tech again and wants to CHARGE US????.

I regret this costly decision as this is not what was sold to us. If this was incorrectly installed all they need to do is let us know while the countertop company is there. But because they are refusing to work with us and come out to see this mess, we can only assume it’s because they know these sinks do this as other reviews show the same issue.

By them not willing to even see this (they are miles within our home), they leave us in a situation where the countop people feel they installed it correctly. It’s a game of finger pointing and someone will be responsible for a new sink and new countertops if that’s the permanent solution.

I'm not an expert but this looks like an installation error to me. It seems like the Corian was covering the top edge of the sink, or maybe ther is caulk on top? But the top edge of the sink should be exposed and at the same level as the top of the Corian. Not covered in any way, it is not an undermount sink and by covering the top edge you are ruining the effect. I don't think you should expect Topzero to resolve this, I would take this up with your counter fabricator.

I've had two Topzero sinks installed in quartz counters for years and they've held up great. Fabricator had to come out at one point to provide extra support from underneath on one of them but they've been great and I love them. Would definitely do it again!

F L:

Your tech is mistaken. There is no reason a TopZero cannot be installed in a solid surface (Corian) countertop.

Fortunately it's a relatively easy fix. I'd build up the bottom of the sink edge and reinstall the sink.

I have extensive experience with TZs. What city and state are you in please?

Ummm too zero sent their guy out he never said the metal was to be flush in line with the counter, the edge is sharp. top zero put a glue on part if it. Their tech claimed corian is too soft yet the owner said it was acceptable. if its an installation issue then why would they not come to neet with our installer to explain??? i asked top zero for an installer, they said they only do work on old sinks being removed . You posted asking peoples experiences yet you've had two good experiences?! I'm sharing my horrible experience and others have had similar. if they felt it was an installation issue why not meet with our installers and help the customer get a goid result with their complicated sink installation - they clear have a product that needs extra attention when instslling why meke it a costly and miserable experience for their customers? then provide a list of trained installers in you area.

???? exactly.

joseph c. — not sure why I cant reply directly- Fort Lauderdale. we went to one of only two corian fabricator’s (that were willing - no one wants corian but I love it). we went with 1/2 ” and they built it up surrounding the sink. if you have any contacts I would appreciatevit but now i want it removed and I’ll go with an undermount if its even doable now. if top zero thrmselves could not fix it ive lost faith.

I first asked about people's experiences with TZ and then I installed them. TZ has training for installers that they are supposed to complete before attempting to install one of these. And the top edge of the sink definitely should remain exposed and flush with the counter surface, as indicated in the attached photos.

FL:

Call Brad at Replace My Sink please.

Thank you Joseph but they are owned by Top Zero here no? I ask because they have a local website/company here that replaces sinks. I will call this company you referred and I appreciate it very much!

And in response to the other guy: NO TOP ZERO WAS THE ONE THAT PUT THIS GLUE OVER THE EDGE OF THE SINK so keep posting photos, it's not what TZ actually did in our kitchen. Also, try getting an actual answer from TZ they change their story. I have save every single email from them prior to buying and if they are not going to help I will have my information documented if I need to go that far.

Top Zero has been horrendous - as I said THEY initially told us they did not install their sinks unless we were removing an old one. When we had the initial issues of cracking we asked for the owner and our countertop installers to meet in person to see if in fact it was the installers issues. At that time, TZ came out with their own tech and he refused to continue to work on Corian. He did a small section, said it was the disposal and put in brackets. Fast forward, it is continuing to crack, and it could very well be an installation issue but UNLESS TOP ZERO CAN STAND HERE WITH OUR INSTALLERS AND TELL THEM, HEY YOU GUYS DID THIS WRONG, we cannot do much. If I call Replace my Sink, they are affiliated with TZ and I should NOT have to pay a dime. Had TZ come out like professionals, tell our installers they were wrong, then they can pay for this mess. I am so livid i would NEVER recommend this to anyone. I contacted both paries PRIOR TO BUYING THIS sink, and no one ever did the right thing. TZ never provided us with the spacers needed for a 1/2" countertop, nor did they come out and just simply state "your installers did this wrong because of a, b, c " this has been hell.

"TOP ZERO WAS THE ONE THAT PUT THIS GLUE OVER THE EDGE OF THE SINK" But it sounds like whoever they are sending is not that competent. Or they were trying to fix an installation problem. I don't think this is standard practice, I've always seen the top edge exposed.

I'd say my TZ is about 1/16 below the surface of the sink. But even in the image you posted, the top edge of the sink is exposed. That is just how it is supposed to be. I have two and I love them.

Did your installer do the training? All the information he needs to do it right should be there. Plus, according to my installer, it's really not that complicated. So maybe your installer isn't skilled enough to execute the installation? In any case, if there is a failure it is due to improper installation and I think expecting TZ to send someone on their own dime to walk your installer through the process is not realistic.

Just have your guy do the training and make it right. Or call someone who has more experience with TZ to fix the mess. Once it is in correctly it won't fail and you will love it. I highly recommend TZ sinks and would do it again in a heartbeat because it looks great and is truly unique. As you know since you wanted it. You're just going to have to get over the hump here, even if it costs you a little extra to get there. Don't snap at people who are trying to help you.

As I said I had a horrible experience and others have too. You asked in your post, if you are so inn love with this sink why post asking peoples experiences?? You sound like you work for them. So be it, enjoy your gems. I hate this sink it has been nothing short of a nightmare. If they are so fing complicated to install then they need to sell these sinks and provide you with one of their installers. I could NOT find anyone on their list that would sell us Corian and install. So. I personally would NEVER use this again in a project for clients. It is not that unique and it scratches terribly. Enjoy your multiple sinks. I will continue to leave reviews on this piece of junk.

As I mentioned before, I started this thread prior to buying it because there was very very little info about these sinks at the time, and I was doing my research. Now I have two TZ and I love them. My experience has been the polar opposite of yours.

When I bought mine, I was warned that I need to have a really good fabricator for this product to work, so I did a lot of due diligence before hiring one. There is no margin for error and it looks like your cutout is not precisely made to fit this sink.

I'm not sure why you are ranting here. If you want help, two people are trying to help you. If you are just here to rant, mission accomplished.

And no, I do not work for TZ. Just because someone likes a product doesn't automatically mean they work for the company who makes it. lol

"Thank you Joseph but they are owned by Top Zero here no?"

Replace My Sink is owned by Bradley Prescott, not TopZero. If they are affiliated, it would be news to me.

F L:

I've installed quite a few Karran 540 sinks, but several years ago, one I installed experienced a delamination issue. It was Karran's problem, but I ate it which is what a reputable fabricator/installer does. Post your cutout dimensions and I'll let you know if one will work; they're great sinks as are properly installed TZs.
