Designing Kitchens and Bathrooms - Replacing kitchen sink cabinet

How difficult is this job? I need to replace my sink cabinet in kitchen.

Do you I have to remove the plumbing - copper pipe etc that comes from the basement completely before putting a new cabinet?

Any ideas, instructions on how to do this? Do this also involve drilling holes in the cabinet base (floor?)

Thanks

1. Turn off water supply to sink.
2. Disconnect all plumbing from sink.
3. Remove sink.
4. Remove counter top.
5. Remove sink cabinet.
6. Install new cabinet, after cutting holes for plumbing pipes.
7. Install counter top.
8. Install sink and faucet.
9. Reconnect plumbing.

If you have a garbage disposal and dishwasher, then you also have to deal with them during this procedure.

This is not impossible, but it will be a challenge. Good luck with your project.

I had an unusual demo this week...master bath on a 8,500 sf house. Cabinets were installed with only 1/2" copper stubbed out. 3/4" cabinet backs. Very neat job. I usually find 2 1/2" holes where the cabinet installer had to cut oversize holes for the stops to fit through.
Now, if this is your situation, you can turn the water off to the house, remove the stops, place a sharkbite endstop on the copper/cpvc/pex and restore your water. They can be removed after you reinstall the cabinetry.
