How Much Does a Bathroom Remodel Cost? A Whatcom County Guide

• Most 2026 bathroom remodels land between $7,000 and $18,000 nationally, with the average around $12,500 [Angi]. A cosmetic refresh can come in under $9,000, a full midrange remodel prices near $26,000 in Cost vs. Value data, and moving walls or plumbing pushes past $35,000 [Remodeling Magazine Cost vs. Value Report].

• Five things move the number more than square footage does: whether the footprint changes, the wet area, tile coverage, fixture grade, and what is behind the walls.

• A tub-to-shower conversion typically runs $3,000 to $10,000, with prefab bases at the bottom of the range and tiled curbless showers at the top [Angi].

• A full remodel takes roughly two to six weeks once demolition starts. Demolition is the fast part; waterproofing cure times, tile work, shower-glass lead times, and inspection dates set the real calendar.

• Permit requirements are set by your local jurisdiction. Plumbing moves, electrical changes, and layout changes usually need one, and unpermitted work resurfaces at sale time. We confirm what applies and handle the applications.

How much does it cost to remodel a bathroom this year? The honest answer is three answers, because "remodel" covers three different projects, and the tier you are in matters more than any national average.

The sources behind those tiers describe them differently, which explains the spread you see online. Angi puts the national average around $12,500, with most projects between $7,000 and $18,000, a population dominated by same-footprint remodels with restrained tile [Angi]. Remodeling Magazine's Cost vs. Value Report prices a fuller midrange remodel near $26,000 and an upscale one close to $80,000, because its standard scope includes more of everything [Cost vs. Value Report]. Neither is wrong. They are pricing different bathrooms.

For Whatcom and Skagit Counties, the useful calibration is that we sit below the Seattle metro on labor rates, and the tier logic holds everywhere: the moment plumbing moves or walls open, the project changes tiers, and no fixture discount claws that back.

Square footage is the least useful predictor of bathroom remodel cost. These five are what actually move it.

• Whether the footprint changes. Keeping the toilet, sink, and shower where they are keeps the supply lines, drains, and vents where they are. Moving any of them means opening the floor or wall, rerouting to code, and adding inspection dates. It is the single most expensive sentence in a design meeting.

• The wet area. The shower or tub surround is the most expensive real estate in the house per square foot: waterproofing membrane, sloped pan, tile, glass, and valve all stack in the same few feet. A prefab surround and a custom tiled walk-in can differ by five figures in the same footprint.

• Tile coverage. Tile is priced by the installed square foot, so the decision between tiling the floor, the floor plus a wainscot, or floor to ceiling moves thousands. Small formats, mosaics, and patterns add labor on top of material.

• Fixture grade. The same list of items, vanity, faucet, toilet, lighting, can be sourced at builder grade or designer grade with a spread of thousands of dollars and little difference in function. The money that must not be cheap is the valve and the waterproofing; the money that can be is most of what you can see.

• What is behind the walls. The one nobody can price from the doorway. Older plumbing, undersized wiring, hidden moisture damage: a later section covers what Whatcom County's housing stock specifically tends to hide, and it is why honest quotes state their allowances in writing.

The single most requested bathroom project locally is replacing a little-used tub with a walk-in shower. Nationally, a tub-to-shower conversion typically runs $3,000 to $10,000: prefab base and surround at the bottom of the range, fully tiled walk-in with frameless glass at the top, and curbless designs above that [Angi].

Conversions cost less than they sound like they should because the plumbing mostly stays put. The drain and valve are already in the wet wall, so the work is demolition, pan and waterproofing, surround, and glass rather than re-plumbing. That also makes them faster than a full remodel, often one to two weeks.

Two local notes. First, waterproofing is the whole game in this climate. A conversion detailed for a dry state fails here, because our bathrooms see more humidity for more months with fewer chances to dry out, and the membrane and slope work you cannot see matter more than the tile you can. Second, think about resale before losing a tub. In a one-bathroom house, the only tub is worth keeping. Where there is a second bathroom, the conversion usually improves both daily use and buyer appeal.

The short version: a cosmetic refresh takes days, a full same-footprint remodel takes two to four weeks of work on site, and a layout change runs four to eight. The long version is about why, because a bathroom schedule does not move at an even pace.

Demolition is the fast part, one or two days, and it is deceptive, because the room then looks ready for everything else at once. What follows is governed by things that cannot be hurried:

1. Cure times. Waterproofing membranes, mortar beds, thinset, and grout each need their cure window before the next layer goes on. Stacking those steps is how showers fail young, so a good tile schedule has quiet days built into it on purpose.

1. Shower glass lead times. Custom glass is measured after the tile is finished, because it is fabricated to the actual opening. That puts a one-to-three-week fabrication wait near the end of the project. A bathroom that is finished except for the glass is on schedule, not stalled.

1. Inspection dates. Where permits apply, rough-in inspections have to pass before the walls close. Those are fixed appointments on someone else's calendar, and the schedule is built around them rather than the other way round.

If it is your only bathroom, say so at the quote stage. Sequencing the work to keep a toilet and some form of shower available as long as possible is a planning problem, and it is solvable when it is planned rather than improvised.

Permit requirements are set by the local jurisdiction, and in our service area that means different counters with different rules: the City of Bellingham, Whatcom County for unincorporated addresses, Skagit County, and the smaller cities each administer their own.

The pattern across all of them is consistent even where the specifics differ. Like-for-like cosmetic replacement, a new vanity where the old one stood, new flooring, paint, generally proceeds without a permit. Moving or adding plumbing, changing electrical circuits, altering ventilation, or touching structure generally requires one, with inspections to match.

The permit is not the enemy of the budget. The rough-in inspection is an independent set of eyes on the plumbing and electrical at the only moment they are visible, and the paper trail protects the sale of the house later. Unpermitted bathroom work does not stay invisible: it surfaces in pre-sale inspections, appraisals, and insurance claims, usually at the worst possible time.

We confirm what your specific project needs with the jurisdiction it sits in and handle the applications as part of our general contracting process, so the permit question costs you a conversation, not a research project.

A lot of the housing stock in Bellingham, Ferndale, Lynden, and the county dates from before 1980, and bathroom walls are where its age concentrates. Three findings come up over and over once demolition opens things up:

• Galvanized steel supply pipe. Common before the 1970s, and it corrodes shut from the inside over decades. If demolition exposes it, the right move is to replace it while the wall is open, because connecting new fixtures to failing pipe wastes the remodel.

• Two-wire circuits and crowded panels. Bathrooms built before modern code often sit on ungrounded circuits without GFCI protection, sometimes shared with half the floor. Current code for a remodel wants dedicated, protected circuits, which can mean electrical work the doorway estimate could not see.

• Fans vented into the attic. Decades of bathroom exhaust ended at the insulation instead of outside, which is how a bathroom project turns up an attic moisture problem. Rerouting the duct to an exterior termination is cheap during a remodel and miserable at any other time.

None of this is a reason to fear the project. It is the reason to prefer a quote that names its allowances for concealed conditions in writing over one that is silent about them. The wall is coming open either way; the difference between contractors is whether what is found was budgeted as a possibility or arrives as a change order with no ceiling. And in every case, the open wall is the cheapest moment that problem will ever have.

As a pure investment, a bathroom remodel returns most but not all of its cost. Cost vs. Value data has a midrange bath remodel recouping roughly 70 to 74 percent at resale, which makes it one of the stronger interior projects and still not a profit center [Remodeling Magazine Cost vs. Value Report].

So the honest answer hangs on why you are doing it. The clearest yes is a failing wet area. A leaking pan, failed grout lines, soft spots at the tub surround: these are moisture problems compounding daily, and in this climate the rot bill grows faster than the remodel bill. Remodeling a failing bathroom is closer to a repair with an upgrade attached than to a discretionary project.

The second yes is a layout that does not work: the one-bathroom bottleneck, the tub nobody has used in years, the shower a knee or a hip can no longer step over. A curbless conversion done now also keeps working if mobility changes later, which is worth building in while the floor is already open.

The weakest case is a purely cosmetic itch shortly before selling. Buyers repay condition more reliably than taste, and at that point the refresh tier, new vanity, lighting, paint, hardware, captures most of the visual gain at a fraction of the cost. A remodel is worth full price when you will live with the result; it is worth the refresh price when you will not.

Every range in this guide narrows to one number once someone stands in the room: your footprint, your wet area, your tile choices, your era of house.
