Don't whack it with anything and it won't crack.

Had a heavily used pedestal sink (pretty sure it was a cheap big box special) in our prior house for 15 years, no cracking.

I'm counting this as two positives. Perhaps I can account for the "cracked reviews" in that people who have bad experiences are often quick to take the time to review.

Mrs Pete I have never heard that. We had one in our last house no problems (and it was the steal of the century - old Kohler model close out for $68 bucks at Lowe's, they just wanted it out of their space). New house we bought another Kohler and no issues there either. They both looked well designed and supported. Both were in the half bath and it gets as much use as any.

I had a pedestal sink (Kohler Memoirs) and it did develop some superficial cracks around the overflow holes ... is it called crazing? The sink was still functional, but it wasn't that old and I didn't think it should be happening. I have a drop in Kohler in another bath and it didn't have that problem. I did eventually replace the top portion of the Memoirs a few months ago (I kept the existing base). I needed to replace the faucet and figured I might as well replace the sink at the same time since I didn't like the crazing.

I had a Kohler Memoirs Stately pedestal in my first home and I never had any issues. The sink was attached at the pedestal and at the wall.

I had the Kohler Memoirs too, and it crackled around the drain. Might have been installer error. :) Also had an original in the house from 1928 and it was perfect. Just hold on to the warranty--at least pedestal sinks are comparatively easy to replace!

Now that I think about it, I have a kohler pedestal sink (Memoirs) in a rental that has those crackles all over.

I have a Toto pedestal sink in my powder room. Eleven yrs of kids and it looks new. No cracks.

Hmmm ... I was hoping my crazed Memoirs was a fluke. Crossing my fingers for this one.

I've had several, one almost 20 years old, none high end, no cracks.

Had 2...no cracks.

I have 3 pedestals that are all 13 now. No cracks. These are vitreous china pedestal sinks.

My Shaw's farm sink, same age, developed some crazing in the bowl last year. That is a fireclay sink and over time fireclay will develop sort of a crackle pattern. That's called crazing -- it's in the glaze. I had that in a fireclay pedestal sink, toilet and bathtub from the 1930s.

It's very different from a crack in the sink. But people complaining don't know what they are buying.

I would go with vitreous china and pay a little more for a good brand.

I purchased a rental house with a badly cracked pedestal sink bowl. I was told the maid dropped something in it. It was ruined!

Then we purchased another rental house with a pedestal sink. We started noticing streaks showing up, we thought were crazing or small cracks.... turned out to be scratch marks from my husbands titanium wedding band. :0) the ONLY thing that took it off was chrome wheel polish....

I shop at The Restore. They have tons of pedestal sink bases.......very few sinks.....

Okay, I'm definitely starting to doubt the reviews I've read, and I can believe that people are saying "cracked" when they really mean "crazing".

Thanks, all. I've decided this is a non-issue.

Crazing is bad too, though, if it allows moisture in. I don't think it makes a bit of difference how the sink is supported when it comes to crazing. Or cracking, for that matter.

I'm pretty sure mine was due to the drain being screwed on too tightly. I'm also pretty sure that Kohler would have replaced it had I inquired. They have sold so many of those Memoir sinks over the years, I'm not surprised that they get mentioned whenever someone says anything about any sink issue.

I've never had a pedestal sink to crack.

I have never had a pedestal sink crack or craze. I have had multiple units in multiple homes of varying ages. I have a Duravit Scola now. In a previous house I had a Kohler memoirs.

Good luck!

I had a pedestal sink (Kohler Devonshire) and it cracked in only a few years. I don't recall a specific bump or bang - and it was superficial, but a hairline crack nonetheless.

i have a memoirs sink. developed spider cracks after a few years. keep getting worse. was installed properly by good plumber. piece of crap in my opinion. ive been in construction over 30 years. wouldnt buy aother kohler prduct even at half price. had american standard in house over many decades, never did this. poor design and even worse quality control. had to take sinktop, toiler and sink base back several times before installing to get one free of defects in casting and finish. overpriced junk

I installed a Toto pedestal sink several years ago in my powder room and I love it. I haven't had a single crack or chip. It doesn't look like Toto makes the same pedestal anymore, which is a shame because it's beautiful and simple. I love how easy it is to clean the sink. You definitely need to build proper support in the wall for the sink. I imagine hitting the sink with something hard could crack it, but the same can be said about a toilet and I would imagine a stone countertop would have the same issue.

I have two installed Memoirs Stately Lavatories installed in my home. Both are the pedestal style basin set on a stone countertop (without the pedestal) The entire top and vanity design is based on the design of this stupid, but beautiful fixture. The effect is AMAZING! The one in the Master Bath is the larger 30" model installed in 2002. It developed crazing after within 3-4 years of installation, first around the drain, and eventually the majority of the basin and the deck. The other sink is the smaller 24" version, installed in the kid's bathroom in 2007. This one does not have any cracks or crazing, it still looks great. ALL of my Kohler faucet cartridges are leaking, so I'm about to undertake that effort... which IS considerably greater with these basins, so I'm debating whether to replace the master sink at the same time, as I recall installing the facets into these fixtures is challenging. Actually, I think I found it MUCH simpler to install the faucets prior to fixing the basin.

I've had issues with the Kohler Memoirs pedestal sink cracking and crazing as well. I'm considering whether to replace the top or install another brand. Disappointing for a Kohler product.

My Kohler Devonshire pedestal sink has a hairline fracture that began when it was less than a year old. It is now two years old and it keeps getting longer. I had it installed by a professional.

I have two memoir sinks. They were installed professionally with blocking behind the tile about 15 years ago. One started developing cracks about 5 years ago. The other started cracking this year. Very disappointing. They are lemons.

I have a Kohler pedestal sink that is cracking around the drain. its 15 years old and nothing was done to it…no repairs or changes in water temp settings. I really expected this sink to last longer than 15 years!
