installation of Kohler Stages - again- using included clips?

9 years ago

Hi, I've posted questions about Stages 45 sink installation before and bbtrix showed her wonderful installation with wood supports.I havn't gotten anywhere with the contractor on the wood supports ever since the countertop installers sent a video showing that they would drill holes in the underside of the soapstone and use undermount clip supports instead. The countertop company is Stonemasters in Kennett Square PA which has great reviews and I know that beekeeperswife had the Stages 33 mounted with clips by Stonemasters into her quartzite.

Only today did I notice that that the Stages 45 sink clips require 3" clearance around the sink

I have standard 24 inch deep cabinets that have 3/4 inch walls , yielding 22.5 inch space front to back.
The bowl of the Kohler Stages 45 sink is 17 inches front to back, (18.5 inches if the lip is included).

There is there fore NOT ENOUGH ROOM in a standard 24 inch deep sink cabinet to have 3 inch clearance both on the front and back of the sink (17" +3"+ 3" = 23 inches, more than the 22.5 inch space available between the front and back walls.

Can the clips be turned on a diagonal to take up 2.75 inches clearance front to back instead? That would allow everything to just fit inside a 22.5 inch cabinet space. Alternatively can smaller clips be used? I have looked at other Kohler installation pdf's and it seems that 2 inch clearance for their clips is more standard so perhaps there is a reason for the 3 inch clips on this sink.

I'm sort of stuck right now because the contractor wants the fabricators of the countertop to deal with the sink installation and their method is the undermount clips which seem to be too big for a standard cabinet.

Any ideas on what to do?
I have another thread on fitting in tip outs and faucet around the sink that I posted before realizing that the clips require 3 inches clearance. I am going to leave that thread for now.

thanks in advance.

Abandon the clips and use a Hercules Universal Sink Harness from Braxton Bragg. Maybe two. That would be ten bucks instead of five.

Trebuchet, My 45" wide stages sink will have the 33 inch deeper portion in 36" space separated by a partition wall from the 15" drawers that are under the shallower "shelf" part of the sink (total 51" cabinet). So it would not work for the HUSH to span the width of the entire sink although it might work for it to span from the end of the larger cabinet to the partition wall. Just not sure how strong that partition wall will be.

if using two do you mean supporting the sink front to back?

The sink rim will be very close to the front cabinet. The clips will be on the sides and back. The front will have another means of support if needed, a bracket or pc of wood. Let the fabrication company handle this.
Many fabricators do not use the supplied clips, but opt for a better solution. As long as they are not depending on an adhesive to hold up the sink it should be fine.

You could do it that way. Use the HUSH. I think I used two on this one:

Scrappy, we also used as many clips as we could in addition to the support. The clips pull the sink up nice and tight to the counter. I do recall that the cabinet space was too tight to use all of the clips. I'll have to ask DH how he improvised.

Thanks everyone for all your help! I opened the Stages sink box and finally found the clips and after all that the worrying, the clips are only 1 5/8 inch long and should easily fit into a 2 1/4 inch space. I don't know why the Kohler diagram is asking for 3 inch clearance. So the clip method may work. Although if the fabrication company adds a wood support or bracket as kevdp4 suggests and bbtrix did so elegantly, I will be more than happy!
