Plumbing Remodel
in West Seattle
Planning a kitchen or bathroom plumbing remodel in West Seattle? Whether you are updating a 1920s Craftsman in Admiral, converting a tub to a walk-in shower in your Alki bungalow, or running gas to a new chef's range in Alaska Junction, Sasquatch Plumbing handles the entire plumbing scope of your renovation. We coordinate with your contractor, pull the permits, pass the inspections, and install every fixture to code.
Why Kitchen and Bathroom Remodeling in West Seattle Is Different
West Seattle is full of beautiful homes with character, but renovating them requires a plumber who understands what is behind those lathe-and-plaster walls. Homes in Admiral, Alki, and Alaska Junction were built between the 1900s and 1960s, and they come with plumbing challenges that newer suburbs simply do not have. Here is what makes West Seattle remodels unique.
The Galvanized Pipe Surprise
Many West Seattle homes still have original galvanized steel supply lines from the 1930s through 1960s. These pipes corrode from the inside, restricting water flow and eventually leaking. If you are planning to tile a new shower or install a modern rain head, replacing the galvanized pipes inside the wall before you tile is critical. Otherwise, you risk tearing out that beautiful new tile work in two years when the old pipes fail. We always assess existing pipe condition during our initial consultation and recommend replacement when warranted.
Cast Iron Drain Lines
Older homes in Fauntleroy and Delridge often have cast iron drain and sewer lines that have been in service for 60 to 100 years. Cast iron corrodes and develops cracks and belly sags over time. During a bathroom remodel, we camera inspect existing drain lines to check their condition. If the cast iron is failing, we replace it with modern ABS or PVC while the walls and floors are already open, saving you from a much more expensive repair later.
Seattle Code and Permitting
Moving a toilet, adding a sink, or relocating a dishwasher requires a plumbing permit from the City of Seattle. The code governs pipe sizing, drain slope, venting distances, and fixture spacing. Seattle permits typically cost $150 to $400 depending on scope. We handle the entire permitting process and schedule all required inspections so your remodel is 100 percent legal, code-compliant, and documented for resale.
Bathroom Plumbing Remodel Services
A bathroom renovation is one of the most impactful upgrades you can make to your West Seattle home, both for daily comfort and resale value. But the plumbing work is the foundation that everything else depends on. Poor rough-in work leads to leaks behind walls, improper drainage, and failed inspections. Our licensed plumbers handle every aspect of bathroom plumbing, from demolition of old fixtures to final trim installation.
- Tub-to-Shower ConversionsConverting old tubs to modern curbless walk-in showers with linear drains. Requires rerouting the drain line and adding a new shower valve and mixing body.
- Fixture RelocationMoving the toilet, vanity, or shower to optimize the floor plan. Includes extending or rerouting supply lines, drain pipes, and vent stacks to meet code.
- Luxury Fixture InstallationInstalling rainfall showerheads, body spray systems, freestanding soaking tubs, wall-mount faucets, and heated towel bars. We work with all major brands including Kohler, Moen, Delta, Toto, and Grohe.
- Adding a New BathroomAdding a half-bath or full bathroom where none existed requires new supply lines, drain connections, and proper venting. Common in basement conversions and ADU additions throughout High Point and Delridge.
- Supply Line ReplacementReplacing old galvanized or polybutylene supply lines with modern PEX or copper while walls are open during the remodel. This prevents future leaks and improves water pressure.
Kitchen Plumbing Remodel Services
Kitchen remodels in West Seattle often involve significant plumbing changes, from moving the sink to a new island to running a gas line for a professional-grade range. The plumbing work must be done correctly the first time because once countertops and cabinets are installed, accessing pipes becomes extremely difficult and expensive. We coordinate closely with your general contractor, cabinet maker, and countertop installer to ensure the plumbing is roughed in at exactly the right locations.
- Island Sink PlumbingRunning water and drain lines to a new kitchen island. This often requires cutting through a concrete slab or routing through floor joists, plus installing an island vent or air admittance valve.
- Gas Line InstallationRunning new gas lines for ranges, cooktops, and ovens. Upgrading from electric to gas requires a dedicated gas line properly sized for the BTU rating of your appliance. Licensed gas work with pressure testing and inspection.
- Pot Filler InstallationRunning a new cold water line to the wall behind your cooktop for a pot filler faucet. Requires running pipe through walls and connecting to the main supply.
- Dishwasher and Appliance HookupsConnecting dishwashers, ice makers, instant hot water dispensers, and water filtration systems. Proper connections prevent leaks and protect appliance warranties.
- Garbage Disposal InstallationInstalling or upgrading garbage disposals with proper drain connections. We recommend InSinkErator units for reliability and carry common models on our trucks for same-day installation.

We coordinate with your contractor or designer. Once demo is complete, we remove old pipes and install new water supply lines, drain pipes, and venting inside the open walls and floor. All rough-in work is pressure tested.

Trim and Finish
After tile, flooring, and paint are complete, we return to install faucets, toilets, shower trims, appliance hookups, and every fixture. We test everything, demonstrate operation, and provide warranty documentation.

Kitchen and Bathroom Remodel Plumbing FAQ
How long does bathroom remodel plumbing take?
The plumbing portion of a bathroom remodel typically requires 3 to 5 days of work spread over 2 to 3 weeks. The rough-in phase takes 1 to 2 days, then we wait for the city inspection and for your tile and finish trades to complete their work before returning for 1 to 2 days of fixture installation and testing. A simple fixture swap can be done in a few hours. We provide a detailed timeline during our estimate so you can plan around the work.
Do I need a permit for a kitchen or bathroom remodel in Seattle?
Yes, most plumbing work beyond a simple like-for-like fixture replacement requires a permit from the City of Seattle. This includes adding new fixtures, relocating drains or supply lines, installing gas lines, and modifying vent stacks. Permits typically cost $150 to $400. Skipping permits creates problems when you sell your home because unpermitted work must be disclosed and can derail a sale. We handle all permit applications and inspections as part of our service.
Should I replace old pipes during my remodel?
If your West Seattle home has galvanized supply lines or cast iron drain pipes and the walls are going to be open during the remodel, we strongly recommend replacing them. A remodel is the most cost-effective time to upgrade old plumbing because you avoid the expense of tearing out finished walls later. We assess pipe condition during our consultation and give you honest recommendations based on what we find, not what generates the most revenue.
Can I use my bathroom or kitchen during the remodel?
It depends on the scope. For a full bathroom remodel, the space will be unusable for several days during rough-in and again during fixture installation. We recommend having access to a second bathroom. For kitchens, we can often stage work so you have running water for part of each day. We communicate our schedule clearly so you can plan meals, showering, and daily routines around the work.
Do you work with my general contractor?
Absolutely. Coordination between trades is critical for a successful remodel. We work closely with your general contractor, electrician, tile installer, and cabinet maker to sequence work properly. Plumbing rough-in happens before walls close up, and finish work comes after tile, flooring, and paint are complete. Our experience with hundreds of West Seattle remodels means we understand the workflow and can prevent costly scheduling conflicts.
What fixtures do you recommend for West Seattle homes?
We recommend fixtures that balance quality, durability, and value. For faucets and showerheads, brands like Kohler, Moen, and Delta offer solid warranties and widely available replacement parts. For toilets, water-efficient models from Toto and American Standard provide reliable performance. For older West Seattle homes with varying water pressure, we often recommend pressure-balancing valves to prevent temperature shocks when a toilet flushes while someone is in the shower.
