| Quick Answer
A primary bathroom remodel in Concord typically costs $45,000 to $90,000, rising above $90,000 where the layout changes or the specification includes a freestanding tub, curbless shower and heated floors. Most Concord primary bathrooms sit between 80 and 140 square feet, which is enough for a separate shower and tub only if the layout is right. |
What you can realistically fit in a Concord primary bathroom
The typical Concord primary bathroom, in homes from the 1960s through the 1990s, is somewhere between 80 and 140 square feet, frequently in a long narrow proportion, with a window on one wall and the entry on the opposite short wall. That geometry drives most of the layout decisions.
Layout one: the wet wall kept, everything upgraded
All plumbing stays on the existing wall. Double vanity replaces single, tub-shower combination becomes a larger walk-in shower, toilet stays where it is with a privacy return added. This is the least expensive route and the fastest, because no drains move. In a 90 to 110 square foot bathroom it usually gives the biggest practical improvement per dollar.
Layout two: shower and tub separated along one wall
Works where the bathroom is at least around twelve feet on its long dimension. Walk-in shower at one end, a soaking tub at the other, both on the same wet wall so plumbing stays consolidated. Vanity on the opposite wall. This is the layout most people picture when they say “primary suite”, and it is achievable in more Concord bathrooms than homeowners assume, provided the tub is a soaking tub rather than an oversized one.
Layout three: the wet room
Shower and freestanding tub share a single waterproofed zone behind one glass panel. It uses less floor area than separating them, looks contemporary, and is very easy to clean. It requires proper full-zone waterproofing, careful drainage design, and good ventilation. It is the most demanding of the three to execute well and the least forgiving of a contractor who does not flood test.
What it costs, by scope
| Scope | Typical Concord range | Timeline on site |
|---|---|---|
| Full replacement, layout unchanged | $45,000 – $65,000 | 5 – 7 weeks |
| Layout change, plumbing relocated | $65,000 – $90,000 | 7 – 10 weeks |
| High specification with structural change | $90,000 – $150,000+ | 10 – 16 weeks |
| Feature | Typical added cost |
|---|---|
| Freestanding tub, including filler and any structural reinforcement | $4,000 – $9,000 |
| Curbless walk-in shower with linear drain | $3,000 – $7,000 above a standard pan |
| Heated floor | $1,500 – $4,500 |
| Frameless glass enclosure | $2,500 – $6,000 |
| Double vanity upgrade from single | $3,000 – $8,000 |
| Steam shower | $5,000 upwards, plus the enclosure and ventilation it requires |
A curbless shower often requires the floor to be recessed, which in a raised-floor Concord home means working between joists. On a slab it is harder and sometimes not viable without raising the whole floor.
What the permit actually covers
A primary bathroom remodel in Concord requires a permit where plumbing, electrical or mechanical ventilation is altered, and where anything structural changes. That covers almost every project in this article. Specifically the permit and inspection process looks at:
- Plumbing — drain sizing and fall, venting, water supply, and shut-offs.
- Electrical — GFCI protection, circuit capacity, the required lighting and receptacle provisions, and correct clearances around water.
- Ventilation — exhaust fan capacity appropriate to the room volume, and correct exterior termination. Venting into an attic is a common and consequential defect in older homes.
- Waterproofing and substrate — the shower assembly, backer board and membrane.
- Energy compliance — Title 24 requirements on lighting and, where relevant, ventilation.
- Structural — anything that touches framing, including recessing a floor for a curbless shower or reinforcing for a freestanding tub.
Moving plumbing does require a permit, and it is worth saying plainly: unpermitted bathroom work is one of the most commonly flagged items in a home sale, precisely because water damage from a bad installation is expensive and insurers ask.
Which upgrades hold their value
A useful distinction is between things a future buyer notices immediately and things only you will appreciate.
- Holds value well: a larger walk-in shower, a double vanity, good layered lighting, quality tile competently set, adequate ventilation, and neutral finishes.
- Holds value moderately: a freestanding tub, heated floors, frameless glass. Genuinely nice, generally appreciated, rarely priced in fully.
- Holds value poorly: highly personal tile or colour choices, a steam shower, and any specification that is significantly above the standard of the rest of the house.
The last point is the one worth taking seriously. A $120,000 primary bathroom in a house whose kitchen has not been touched since 1985 returns less than the same money spread across both rooms.
Where you can save without regretting it
- Keep the plumbing where it is. The largest single saving available, and layout one above shows it need not compromise the result.
- Choose a large-format porcelain over natural stone. Lower material cost, faster to set, and no sealing.
- Use a standard-size shower pan rather than a custom one, where the layout allows.
- Skip the second sink if the room is genuinely tight. A single wide vanity with good storage often works better than two cramped basins.
- Do not save on waterproofing, ventilation or electrical. These are hidden, they are what fails, and they are the most expensive things to put right after tiling.
- Do not save on blocking for future grab bars. It costs almost nothing at rough-in and is very expensive later.
Frequently asked questions
How much does a master bathroom remodel cost in Concord?
Typically $45,000 to $65,000 for a full replacement keeping the layout, and $65,000 to $90,000 where plumbing moves. High-specification projects with structural change run above $90,000.
How long does a primary bathroom remodel take?
Five to seven weeks on site keeping the layout, seven to ten weeks with a layout change, and ten to sixteen weeks for high-specification projects. Materials should be on hand before demolition begins.
Do I need a permit to move plumbing in a Concord bathroom?
Yes. Altering plumbing, electrical or ventilation requires a permit, as does anything structural. Unpermitted bathroom work is one of the most commonly flagged items in a home sale.
Can I fit a separate shower and tub in a typical Concord primary bathroom?
Often yes, if the room is around twelve feet on its long dimension and both sit on the same wet wall, using a soaking tub rather than an oversized one. A wet room where both share one waterproofed zone uses even less floor area.
Is a curbless shower possible in my home?
On a raised floor, usually the floor can be recessed between joists. On a slab it is harder and sometimes requires raising the whole bathroom floor, which affects the doorway and any adjoining floor level.
What is the best thing to spend extra on in a bathroom?
Layered lighting, ventilation sized correctly for the room, and competent waterproofing. All three are noticed daily, and the last two are what prevent expensive failures.
