Ugh....

Woke up this morning and headed down stairs to make breakfast. I walked into the kitchen noticed something was off. My kitchen sink was sitting in the bottom of the cabinet.

Turns out whoever installed the under mount sink in my kitchen didn't use any clips. They just siliconed and epoxied the sink to the granite slab and figured that would be enough to hold it up. It held it for almost 2 years.

Any tips to keep this from happening again? I am going to the Depot shortly in hopes of finding whatever supplies I need to put this thing back together.

No tips, but wow that's a new one to me. I thought a lot of sinks had enough overhang that even if they could shift, would still be larger than hole/not fall through. They made original opening too big then just rested a little lip on it?

This sink is an under mount so it is mounted beneath the countertop opposed to a traditional style sink that rests on top of the counter.

Actually the method you listed is the way it is done. They are simply siliconed/glued on. It is likely that the installer didn't do a good job prepping the surfaces. There are plenty of tutorials online and on you tube. Use PL400 for the glue, run a 2x4 over the countertop and clamp up through the drain holes to the 2x4 to clamp it up tight to the counter top while it sets.



If you like you can glue additional blocks of wood to the underside for additional support in holding the sink up to the underside of the counter.

Sorry to hear it.

but, from my perspective, it was pretty funny to hear.

While this may be adequate for a stainless sink I would not recommend it for a cast iron or granite. Clips or bars are the way to go. Using glues or epoxies will make it damn near impossible to swap out a sink at a later date.

Drill clips into a granite or other stone top you will likely crack it. Yes a heavy sink like a cast iron sink would likely be done differently with bracing. Even when clips are used they are still just glued to the bottom of the stone in the same way.

You are correct, it is not a job for the average DIYer, but my installers use threaded sleeves epoxied into the granite with either clips or metal u-channel, depending on sink material. I will never allow them to use glues or epoxies to install sinks.

This is all good to know, I am thinking of going this route when I remodel my kitchen.

Well... I decided to hire a contractor to fix the sink. The sink was fixed Monday night and just fell back into the bottom of the cabinet this evening.

Hopefully the contractor comes back here and makes it right.
