How Much Does a Bathroom Remodel Cost in Boise? (2026)

The short answer

Nationally in 2026, the two datasets we cite put a full bathroom remodel at $6,456–$24,715 with an average of $15,586 (This Old House, updated July 2026) and at $6,600–$18,000 (NerdWallet, updated February 2026). A basic refresh comes in under $10,000. High-end work is where the two part company: This Old House puts high-end remodels at $27,492–$35,808, while NerdWallet says an extensive high-end remodel “can cost over $80,000” — which is a difference in what each calls high-end, not a contradiction. Note that This Old House prices a master/primary bath (130+ sq ft) at $22,370–$24,715, so a master bath is not automatically a $30,000 project.

For Boise specifically, no independent dataset prices bathroom remodels at the city level. The local figures below come from a single Treasure Valley contractor’s published price guide, flagged as directional rather than independent, and the national datasets are exactly that — national. Where a widely repeated local claim can be checked against government data, we check it: see the section on whether Boise runs above national averages.

National cost by size (2026)

This Old House (2026) reports a national average bathroom remodel of about $15,586, and breaks the cost down by the size of the room. Larger rooms cost more not just in materials but in the labor, plumbing runs, and square footage of tile and flooring.

National cost by finish level (2026)

Finish level moves the number even more than size does. The same room can be a budget refresh or a high-end renovation depending on the fixtures, tile, vanity, and how much of the plumbing and layout you change. This Old House (2026) groups projects into three tiers.

What other national sources say

Independent cost datasets vary because they survey different projects and regions, so it helps to see more than one. NerdWallet (2026) cites a typical range of $6,600–$18,000 — with high-end projects topping $80,000 — and a per-square-foot cost of roughly $70–$250, in the same ballpark as This Old House’s by-size figures above.

Taken together, for planning purposes: This Old House puts a midrange 50 sq ft remodel at $14,609–$19,040 and high-end work at $27,492–$35,808, and NerdWallet puts an extensive high-end remodel above $80,000. The gap at the top end reflects how far “high-end” can be taken, not a disagreement about ordinary projects — both sources put those in the mid five figures or below.

Bathroom remodel costs in Boise

There is no large independent dataset that prices bathroom remodels at the Boise city level, so the local figures below come from a Treasure Valley contractor — Pristine Kitchen & Bath — and its 2025/2026 Boise price guide. Treat these as directional: they reflect one local contractor’s pricing rather than an independent survey, but they are useful for understanding how Boise compares.

A version of “Boise runs above the national average” circulates widely in local remodeling content, including in the price guide above, usually explained by local labor costs. That explanation does not survive contact with the wage data. In the U.S. Bureau of Labor Statistics’ May 2025 Occupational Employment and Wage Statistics, construction and extraction occupations in the Boise City metro area averaged $28.58 an hour against a national average of $31.42 — Boise construction labor is paid below the national figure, not above it.

Boise labor and permit costs

For projects priced by the hour or by trade rather than as a package, the same Pristine Kitchen & Bath (2025/2026) guide lists local labor rates and typical permit fees. Permit fees vary by jurisdiction and the scope of work; your city or county building department is the authority on what your project requires.

• General contractor: $75–$125/hr
• Plumber: $85–$150/hr
• Electrician: $80–$130/hr
• Tile installation: $6–$15/sq ft
• Building permit: $100–$500
• Plumbing permit: $75–$300
• Electrical permit: $50–$200

Specific projects: tub-to-shower and accessible bathrooms

A tub-to-shower conversion is usually one of the more affordable bathroom projects, because it often reuses the existing footprint. Cost scales with scope: a prefab or acrylic unit swap sits at the low end, while a fully custom tiled walk-in shower sits at the high end. The biggest cost drivers are whether the plumbing has to move and the materials you choose — see our dedicated walk-in shower vs. tub-to-shower guide for how to decide, and what a full shower replacement costs for a deeper breakdown of that project on its own.

Accessible and aging-in-place work is priced by feature rather than as one band, which is the honest way to plan it — you are buying the specific changes the household needs. Fixr (2025) prices grab bars at $85–$300 installed, a curbless shower conversion at $750–$3,000, a walk-in tub at $5,000–$8,500, widening a doorway at $300–$2,500, an accessible wall-mounted sink at $450–$800, and a raised or accessible toilet at $100–$1,600. Add the features you need to the cost of the underlying remodel; Fixr does not publish a single all-in accessible figure, and neither should anyone else.

Does a bathroom remodel add value? The ROI picture

Two legitimate resale numbers get quoted, and they disagree because they measure different things. Remodeling magazine’s 2025 Cost vs. Value Report estimates that a midrange bathroom remodel recoups about 80% (79.9%) of its cost at resale nationally — the highest figure since 2007, up from 73.7% in 2024. That same report puts a Universal Design (accessible) bathroom at about 64.1% and an Upscale remodel at about 42.2%.

The NAR 2025 Remodeling Impact Report, by contrast, has Realtors estimating that a bathroom renovation recovers about 50% of its cost. The gap is methodological, not contradictory: Cost vs. Value uses estimated sale-price recovery, while NAR surveys Realtors’ perceptions of value. NAR also notes that a bathroom renovation is among the top projects in homeowner demand. Both numbers are worth knowing; neither is "the" answer on its own.

A critical honesty note for Boise readers: Idaho was excluded from the 2025 Cost vs. Value city-level ROI dataset, so there is NO published Boise- or Idaho-specific bathroom ROI figure. Do not trust any source that quotes one. The closest published regional proxy is the Mountain region, where the midrange bathroom ROI runs lower than the national figure — roughly 69–71% — while the Pacific region is the highest at about 91% (Remodeling/JLC Cost vs. Value Report; regional data — primary report site restricts access). Note, too, that exact dollar figures from the Cost vs. Value report are approximate here for the same reason.
