Hi Joseph, do you think the Pete’s mount would work well with the Kohler Irontones cast iron 33” sink? I’m worried that the little feet might make it difficult. I heard front ones are different height than back? My stone installer was planning on creating a support with horizontal 2x4’s on walls of cabinet and I am not sure about this. But I’m not that expert. Which would be best for this sink? Thank you

I'd still use the Pesimoki. Wood blocking cannot push sinks against the bottom of a top. I've seen too many blocked leakers.

Thanks Joseph. Also - the countertop installers - installed the marble countertop first and cut sink opening in place due to a very long run with an L at end also. They were worried about sink hole breaking in transit.
Have you installed the Pete sink mount after countertop was installed and put sink in from underneath? I want to be sure this will still work well and we won’t have trouble since will differ from regular mounting method on Pete’s video. And installers haven’t used this mount before. I hope they can figure it out. I’m sure placement / height of mount will have to differ to allow to get sink inside after mounting metal? Thanks so much for your help and advice.

@carliecarlieq, couldn't you install sink on Pete's sink mount for templating the countertop and then remove the sink prior to countertop install and then reinstall the sink underneath after the opening is cut? As long as the sink clears the sink mount brackets, it shouldn't be too difficult to reinstall underneath the countertop. Otherwise, it will become a more difficult install if you have to install the sink plus mounting brackets from underneath the countertop. If it is a heavy cast iron or farm sink, that will also add to the complexity and difficulty of installing from underneath.

@carliecarlieq we installed Kohler's Riverby sink with Pete's sink mount. It was a little challenging but not impossible. Riverby also has different height feet. Plus the rear drain position is close to the right left foot. We ended up placing a small piece of aluminum under all the feet to elevate the sink off the Pete Sink Mount rails, which gave us the clearance we needed between the drain and foot and to be able to shift the weight of the sink closer to the center of the rails.

Thank you but countertop is already installed and sink hole cut but no mounts installed yet. That’s why I am asking if should still use the Pete Sink Mount. Wish was done prior but can’t change that now. Just want to know if I should let them use 2x4’s as they were going to do or make them use Pete which they never have used. And differs from usual method since countertop is in now. Also...It’s a custom home and I don’t want this to be done wrong or be makeshift (cheesy :)
Thanks so much. Hopefully we can figure out what to do.

@carliecarlieq if the installers had two jacks, they could support the sink while the Pete's sink mount is placed in position. I don't think your sink will have to be raised above the rails because your sink has a center drain. I prefer the look of the sink mount as opposed to having 2x4s cluttering up the cabinet, very happy with choosing to use the mount kit. Pete is great with answering questions.

Thank you very much.

"Have you installed the Pete sink mount after countertop was installed and put sink in from underneath?"

It's the only way I've ever used a Pesimoki and I've done it at least 3 times. It may sound counterintuitive, but after-the-top is the best way to install a sink. The top is where is goes; you simply dial the Pesimoki up to the bottom of the top. Perfect.
