A bathroom is the room you use first and last every day, so a remodel pays off in small things, like a shower that drains well and a fan that clears the steam. New Day Construction is a design-build team, and we take bathrooms from the first layout sketch to the final walkthrough. We work in King County and Snohomish County, and this page is for Covington homeowners who want to know what the job involves, what it costs, and how long it takes.
Many Covington houses date from the 1990s and 2000s, so the bath you want to replace is often a builder-grade room with the original tub and a fan that barely moves air. That is a good starting point for a remodel, because the plumbing and framing are usually easy to read once the walls are open.
Choose the layout and fixtures
Think about how many people use the room, what has to be stored, and whether a shower, a tub, or both fit your household. A vanity and mirror should suit the space you have. Changing the layout affects plumbing and framing, so we review the existing room before you commit to a design.
We do tile and vanities inside a full bath remodel and not as separate small jobs, because waterproofing and plumbing have to be planned together. If you only need a tub swapped in a day, a bath-refit specialist will likely be faster and cheaper, and we will tell you so.
Surfaces designed for a wet room
Tile, shower surrounds, flooring, and countertops decide how the room looks and how much upkeep it needs. Ask any contractor how the shower pan will be waterproofed, along with the floor transitions and every penetration. Choose materials by how you use the room, and confirm which products are included in the written scope.
Finish choices move the price more than the size of the room does. A large tile of about 2x4 ran about $75 per sq. ft. to install in our fall 2026 estimates, while a small 6x6 tile across the whole bath ran about $95 because there are many more pieces to set.
Storage, lighting, ventilation, and accessibility
A remodel is the moment to add niches, reachable storage, layered lighting, and a quieter, stronger fan. If easier access matters now or later, discuss entry height and clearances early. Accessibility and aging-in-place bathroom work starts from $10,000 on our price list (price list, November 2026). The existing structure decides which features fit.
How much does a bathroom remodel cost in Covington?
Starting prices from our list, all as of November 2026:
| Project | Starts from |
|---|---|
| Bathroom design | $1,000 |
| Small or guest bathroom remodel | $20,000 |
| Shower remodel | $20,000 |
| Full bathroom remodel | $25,000 |
| Primary bathroom remodel | $45,000 |
| Bathroom addition | $75,000 |
Our rough fall 2026 benchmarks match that range. A powder room with a new floor, toilet, vanity, mirror, lighting, and paint runs near $20,000. A standard 4x8 bath with a tub and shower, new vanity, toilet, and tile around the shower runs near $35,000, and a primary bath with a separate shower and tub and a double vanity starts near $50,000. A luxury primary bath goes past $80,000.
These are starting points and not quotes. Concealed problems may show up only after demolition, so compare bids by what each one includes, allowances included, and by how it handles an unexpected condition. Our aim is to be on budget and on time. On a $100K quote, the final figure should land near $103K, and a jump to $160K would need a real reason, such as scope you add or a hidden condition nobody could see before the walls came open.
Permits and inspections
Requirements depend on the work. Cosmetic updates usually need less review than moving plumbing or changing walls, and electrical work has its own rules. Covington is a King County city, so confirm what applies to your address with the City of Covington's permit staff before work starts. Washington issues electrical permits through Labor & Industries, and the plumbing and building steps follow the city's process.
As a general contractor, we coordinate required inspections, and on our Lake Forest Park job permits were part of the estimate. Review times vary by city, from about six weeks to three months on jobs we have seen.
From planning to the final walkthrough
Start with your priorities and budget range. We review the room, settle the layout and fixtures, then the finishes, and put the agreed work in a written proposal. The schedule depends on the scope and on the delivery of materials, and made-to-order items add lead time. Before construction we agree on access and on how we communicate. Settle a few questions early. Will this be the only bathroom during construction? Which products must be chosen before work starts? Who coordinates the inspections? Where will materials be staged?
If you stay home, tell us up front. We try to keep one bath working, and about nine times in ten we build the schedule around how the household lives.
A recent bathroom and laundry remodel in Lake Forest Park
This job is not in Covington. It is in Lake Forest Park, in King County north of Seattle, and we include it because it shows how we price and hand over a bathroom.
Daniel's bathroom and laundry room had not been touched since 1984, while the rest of his house, including a kitchen he had updated a couple of years earlier with another contractor, was up to date. He came to us on a friend's recommendation, and we gave him two options. A semi-custom remodel came to $46,000 and a fully custom one to $54,000, a difference of about $8,000, or 17%. Both estimates included materials, labor, demolition, haul-away, and permits.
After a visit to our showroom, Daniel chose the custom version because the catalog line did not offer the colors and finishes he wanted. The shower tile predated current waterproofing standards. It looked fine, but demolition and substrate prep needed more attention than they would in a recently remodeled room. Our project manager Max, who has years of experience as a casework installer, knew which cabinetry could be refreshed and which deserved to be replaced.
The work ran from mid-March to mid-May 2026, less than two months from start to handoff. The final cost came to $54,000, exactly the figure quoted at the estimate stage, paid in two installments, one before work began and one after handoff. Daniel received the full warranty documentation package, and the new rooms match the rest of his house.

Frequently Asked Questions
Short answers to what Covington homeowners ask before a bathroom project starts.
How much does it cost to remodel a bathroom in Seattle?
Around Seattle a full bathroom remodel starts from $25,000 on our price list as of November 2026, and a primary bath from $45,000. Our fall 2026 benchmarks put a powder room near $20,000 and a standard bath near $35,000, with primary baths at $50,000 or more. Finishes drive the gap more than square footage does.
What are the major construction companies in Seattle?
We do not rank other firms. Seattle has many registered contractors, and the useful comparison is the same for every one. Check the registration, plus bond and insurance, in the L&I Contractor Verify tool, ask for the written warranty and ask to see finished work like yours.
How much does a GC make per house?
Contractor margins differ from firm to firm, and we do not publish ours. What matters to you is the price you sign and the price you pay. Ask each bidder for a written scope with allowances marked, and ask how hidden conditions and change orders are handled.
What is the 30% rule in remodeling?
It is a rule of thumb that you will see online, and it suggests keeping total remodeling spend near 30% of your home's value. It is a guideline and not a code or a law, and it will not fit every house. A bathroom budget works better when it starts from your plan and the finishes you want.
How long does a bathroom remodel take in Covington, WA?
Our Lake Forest Park bath and laundry job ran from mid-March to mid-May 2026, under two months from start to handoff. Permits come on top, from about six weeks to three months, and made-to-order cabinetry adds lead time. You get a written schedule once the scope is set.
What services are included in a bathroom remodel?
A full remodel covers demolition, plumbing and waterproofing, tile, the vanity, toilet, tub or shower, fixtures, lighting and paint. A powder room is a smaller version of the same scope. We coordinate permits and inspections, design is part of the job, and we do not take small stand-alone jobs.
