Deep Kitchen Sink

by Greg Zimmerman

Replace the shallow kitchen sink with this restaurant quality deep sink and high rise faucet.  The Krowne HS-1419 includes a heavy duty metal faucet and a drain basket. The installation requires cutting the existing sink opening about 1/2″ deeper, drilling 4 holes for the mounting studs, and drilling new 1″ holes for the faucet.  The water lines will reach without modification, but the drain needs to be modified.  I used Little House Custom’s kitchen Hepvo valve kit which removes the P-trap to keep useable storage in the under-sink cabinet. 

Here’s the tiny Casita sink
Old sink out and new one ready to test fitting

Start by loosening the 6 screws under the kitchen sink, remove the P-trap, water lines and faucet. Pull the sink out and lay the new sink in place.  Mark across the back where the fiberglass needs to be cut. I use a cut out tool and roto-zip bits.

The pencil line is how much material to remove. I wear eye/hearing protection and a respirator.

Once the sink will sit down so the studs lay on the counter, mark them and drill 1/4″ holes.  The sink should now lay flat.  Pencil in the circles for the faucet and drill the 1″ holes.

Now for the fun part, it’s a very tight fit to crawl under the sink through the cabinet door opening.  Reaching up from the underneath install the 4 wing nuts to hold down the sink.  Next put the faucet washers and nuts on, attach the plumbing lines, and install the kitchen sink Hepvo valve.  That requires cutting the drain pipe to the appropriate height and lining everything up before glueing the PVC fitting and screwing the rest together.

I’ve now done 5 of these sink here’s an update:  Instead of 1″ holes for the faucet, I drill 2″ holes and pre-install the faucet to the sink before dropping the whole unit in.  Much easier and less chance of a leak.  I also silicone the rubber gasket to the drain on the sink to help everything stay sealed.

Hi, Greg! I’d like to try this on a 2017 Independence Deluxe. Have you tried this, or do you know anybody who has, so I can get advice, directions, and maybe pictures? Thanks, love your work!!!

Nope I have not. I’ve looked at a few Independence and Liberty’s with the “drivers side” kitchen and I don’t think it will work. The spacing of the faucet doesn’t match where the Krowne sink’s location is. Also if those layouts have a furnace, there’s no room for it.

Where did you get the faucet handles. The sink referenced and link comes with regular turn handles.

The faucet and handles come with the Krowne sink.
