A master bathroom retreat is usually the largest and most expensive bathroom in the house to remodel — more square footage, more fixtures (often a double vanity, a soaking tub, and a separate shower), and higher-end finishes than a hall or guest bath. That combination pushes the typical budget well above a standard bathroom project, and it multiplies the effect of both Washington sales tax and Clark County's wet-season moisture load.
This guide uses This Old House's 2026 master-bathroom-specific cost data, cross-checked against Bob Vila's 2024 primary-bathroom figures, to show what a realistic budget looks like by tier and by line item. We also state Camas Bath's own published range for a master suite in Clark County. If your bathroom is on the smaller side instead, our small bathroom remodel cost guide is the better starting point.
Key takeaways
- This Old House (2026) prices a national master bathroom remodel at $12,005–$24,715 (average ~$18,360); Bob Vila (2024) prices a primary bathroom wider, at $15,000–$55,000.
- By tier: basic refresh $12,005–$17,516, mid-range $15,648–$20,130, premium/luxury $18,920–$24,362+ (This Old House, 2026).
- Plumbing is typically the single largest line item at roughly $5,545, ahead of cabinetry (~$2,929) and drywall/insulation (~$2,338) (This Old House, 2026).
- Heated flooring and properly sized exhaust ventilation matter more in a master suite here than the national averages suggest, given a larger wet footprint and a Northwest winter.
- Camas Bath's published range for a Master Bathroom Remodel is $28,000–$60,000+, above the national tiers — reflecting a full custom layout, Washington sales tax, and premium finishes as standard.
The short answer
This Old House (2026) puts a master bathroom remodel nationally at $12,005–$24,715, with an average around $18,360. Bob Vila's 2024 bathroom-remodel breakdown prices a primary/master bathroom higher, at $15,000–$55,000, reflecting the wider range of scope a master suite can cover — from a cosmetic refresh to a full spa-style rebuild.
Both figures are national. Camas Bath's own published range for a Master Bathroom Remodel is $28,000–$60,000+, which sits at the upper end of both national datasets. Part of that gap is Washington sales tax on labor and materials (8.8% inside Camas as of Q3 2026, per the state Department of Revenue), and part is the premium-tier scope — a double vanity, a soaking tub, and full waterproofing — that a Clark County master suite typically calls for.

Where the money goes: line items
This Old House (2026) also breaks a typical master bathroom budget down by trade and material category, which is useful for seeing where a remodel budget concentrates.
- Plumbing: $5,545 (This Old House, 2026)
- Cabinetry: $2,929 (This Old House, 2026)
- Drywall and insulation: $2,338 (This Old House, 2026)
- Tiling: $1,326 (This Old House, 2026)
- Shower/tub combo: $1,258 (This Old House, 2026)
- Flooring: $1,114 (This Old House, 2026)
Why heated floors and ventilation earn their line item here
A larger footprint means more tile surface losing heat in a Northwest winter and more humidity generated by a soaking tub plus a separate shower running at the same time. Heated flooring, which This Old House (2026) groups under its premium/luxury tier, is a genuinely useful upgrade in a climate where the room can otherwise sit cold and damp much of the year — not just a spa amenity. The same logic applies to exhaust ventilation: a master suite with two wet zones needs a fan sized and ducted for the combined moisture load, not the single-shower assumption a builder-grade bathroom was designed around. Both belong in the budget conversation from the start rather than as late add-ons.
Cost by square footage
Size matters almost as much as tier. This Old House (2026) prices out a 100-square-foot and a 150-square-foot master bathroom at both the cosmetic and full-renovation level.
| Size | Cosmetic refresh | Full renovation |
|---|---|---|
| 100 sq ft | $12,005 | $19,166 |
| 150 sq ft | $16,708 | $24,715 |

Camas Bath's published range
Camas Bath's own published range for a Master Bathroom Remodel is $28,000–$60,000+, which reflects a double vanity, a soaking tub, natural stone, and a fully custom layout as the standard scope rather than a cosmetic refresh. NerdWallet's 2026 general bathroom data (roughly $70–$250 per square foot, up to $80,000+ for extensive high-end projects) is consistent with the top of this range once a larger master footprint, premium finishes, and Washington sales tax are factored in.
A larger master project in Camas, Vancouver, or unincorporated Clark County will also need a permit for the plumbing and electrical work involved — the office covering your address (City of Camas Building Division, City of Vancouver Permit Center, or Clark County Community Development) can confirm what applies before you finalize a scope. If your bathroom is closer to a hall or guest bath in size and scope, our small bathroom remodel cost guide covers that budget range instead — the two projects rarely share a similar total.
