Kitchen Remodel Plumbing in Kitsap County, WA: What to Expect & What It Costs
Kitchen remodel plumbing in Kitsap County typically runs $2,500–$7,500 for a standard sink relocation with a dishwasher line, and $4,000–$8,000+ if you’re adding a kitchen island with a sink or gas cooktop. The exact cost depends on how far the water, drain, and (if applicable) gas lines have to travel from their current location — a minor shift along the same wall is inexpensive, while moving plumbing across the room to a new island is the single biggest cost driver in most kitchen remodels.
Why Kitchen Plumbing Costs More Than People Expect
Homeowners planning a kitchen remodel often budget for cabinets, countertops, and appliances — then get surprised by the plumbing line item. That’s because moving a sink, dishwasher, or gas range isn’t just running new pipe; it usually means opening walls or floors, rerouting supply and drain lines through joists, adding new vent lines so the drain works correctly, and patching everything back up afterward. The further the fixture moves from its original location, the more of this hidden work is involved.
What Drives the Cost
| Scope | Typical cost |
|---|---|
| Minor sink shift (same wall, few feet) | $500–$1,500 |
| Sink relocation across the room | $1,500–$5,000+ |
| Moving plumbing to a new kitchen island | $1,200–$6,000+ |
| Gas line for a range or cooktop | $650–$2,000 |
| Standard full sink + dishwasher relocation | $2,500–$7,500 |

Moving a Kitchen Sink: What’s Actually Involved
A same-wall sink shift is usually straightforward — extend the existing supply and drain lines a few feet and reconnect. Moving a sink across the room, especially to a new island, is a different project entirely: it typically requires cutting into the floor, running new supply and drain lines through or under the joists, and adding a vent (or in some cases a macerator pump if gravity drainage isn’t feasible) so the fixture drains properly under Washington’s plumbing code. This is the step homeowners most often underestimate when planning an island with a prep sink.
Adding a Gas Line for a Range or Cooktop
If your remodel includes switching to gas cooking or relocating an existing gas range, that’s a separate scope from the water and drain work. Gas line installation runs roughly $1–$10 per linear foot for the line itself, plus fixture and connection costs, and always requires a licensed plumber and permit — this isn’t a DIY-safe project. Pelican Plumbing handles gas line work as part of kitchen remodels throughout Kitsap County alongside the water and drain scope, so it’s coordinated as one project instead of two separate contractors.
Frequently Asked Questions
How much does it cost to move plumbing for a kitchen remodel in Kitsap County?
Most projects fall between $2,500 and $7,500 for a standard sink and dishwasher relocation. Moving plumbing to a new kitchen island typically adds $1,200–$6,000+ depending on how far the lines have to travel and whether venting or a macerator pump is needed.
Do I need a permit to move plumbing during a kitchen remodel?
Yes. Relocating water, drain, or gas lines requires a permit in Kitsap County, and the work must be done by a licensed plumber. Skipping permits on plumbing work can create real problems at resale, when the county requires proof the work was inspected.
Can I add a sink to my new kitchen island?
Yes, but it’s one of the more involved parts of a kitchen remodel — it usually requires new supply lines, a drain routed through the floor, and proper venting. Costs for island plumbing typically run $1,200–$6,000+ depending on your home’s layout and whether a macerator pump is needed.
How long does kitchen remodel plumbing take?
A same-wall sink relocation can often be completed in a single day. Island plumbing or gas line additions that require opening floors or walls typically take several days, and should be scheduled early in the remodel timeline — before cabinets and flooring go in.
Should I hire a plumber before or after choosing my kitchen layout?
Before finalizing it. Getting a plumber’s input on where the sink, dishwasher, and gas line can realistically go (and what it will cost to move them) before you commit to a layout can save significant money compared to redesigning around plumbing constraints discovered mid-project.
