Installation Information


Rated 5 out of 5 by from Worked perfectly! We had 4 beautiful faucets that we wanted to keep after installing quartz countertops - not to mention the cost savings of not having to replace the faucets. The thick deck mounting kits worked perfectly and were easy to install!

Rated 5 out of 5 by from Perfect fix Building a new home and had no idea our marble would be too thick for the faucet. This fixed it!

Rated 1 out of 5 by from Design Flaw Agree with prior reviewer - faucet should be designed to accommodate standard thickness of most natural stone slabs or 3 cm. Should not have to order "an extension"

Rated 5 out of 5 by from For powder room Faucet This did the trick to get our powder room faucet installed through an extra thick piece of granite. Worked like a charm!

Rated 1 out of 5 by from Delta Design Flaw The need for this points out a major design flaw affecting Delta products. Namely the standard won't work on 2 CM granite. Interesting that it is only the spout that won't fit. Really stupid design. Kohler does not have this problem.

Rated 5 out of 5 by from Must have for Delta install on quartz counter top Works as described. If you are mounting your Delta faucets on natural stone or quartz counter tops this kit is a must.

Rated 5 out of 5 by from Loose faucets due to 1 1/8 inch granite counter top. I bought two of these recently and installed them myself. They are exactly what I needed to convert sloppy loose faucets into firmly installed ones. Thank you.

will this work with model 35984lf-bn-eco 301-116

Asked by: ar
Hi ar, Thank you for your question. Unfortunately, this kit will not work with the spout for the 35984LF-BN-ECO, but should work with the valves. We do not make an extension that works with the spout. Best regards, Jon

is it possible just to purchase the extension for the spout (not the handles)?

Asked by: Michael
Hi Michael, Thank you for your question. The spout extension nut and washer from the RP10612 extension kit is available separately as RP36203. Thanks, Dave

Will this fit Delta faucet 3551LF?  I don't see any fitment charts. If not, which extension kit do I need? Thank you, Larry

Asked by: Larry
Thank you for your inquiry, Larry! The Delta Dryden Lavatory 3551LF faucet has a maximum deck thickness of 1 1/8" (29 mm). However, the thick deck mounting kit that will add 1" more to the shanks of the faucet. The thick deck kit is RP10612. https://media.deltafaucet.com/SpecSheet/dsp-l-3551_F.pdf Best regards, Tanya

Need to order RP10612 to install my bath faucets. Do I need to specify the finish? I have stainless steel finish.

Asked by: Lori
Thank you for your question. Delta Faucet model RP10612 is a thick tile mounting kit that is installed underneath the sink so it does not need a finish designation.

Would the kit work on a single hole or a 4"cc as well? Or are these only set up for ws faucets?

Asked by: NJA
Hi NJA, Thank you for your question. Delta Faucet model # RP10612 will only function on our widespread faucets. We do not offer a thick deck mounting kit for the 4" centerset faucets. Thanks. Jody
