Bathroom Remodel Cost in Idaho — Powder, Full, and Primary Suite
What a bathroom remodel actually costs in Idaho in 2026 — three size bands, a line-by-line breakdown, tub-to-shower conversion pricing, honest regional variance across Treasure Valley, Magic Valley, East Idaho, and North Idaho, and the Cost vs. Value ROI you should expect at resale.
Quick answer
In the Treasure Valley in 2026, a powder-room remodel runs $6,000–$15,000, a standard full-bath runs $12,000–$45,000, and a primary suite runs $25,000–$95,000. A tub-to-shower conversion typically runs $6,000–$15,000 as a standalone project. Labor is 40–50% of the budget (bathrooms use six to eight specialized trades — plumbing and electrical are separately licensed in Idaho). National Cost vs. Value ROI for 2024: mid-range bathroom 74%, universal-design 55%, upscale 45%. Iron Crest Remodel (RCE-6681702) works bathrooms across the Treasure Valley plus Kuna, Middleton, and Emmett; figures here reflect actual 2026 estimates from that market and are directional for other Idaho regions — get a local bid to confirm.
Quick answer
In the Treasure Valley in 2026, a bathroom remodel falls into three size bands. A powder room or half-bath remodel runs $6,000–$15,000 (vanity, toilet, flooring, paint, lighting — no shower or tub, so no waterproofing complexity).
Bathroom size drives the total more than any other single variable, but the relationship is not linear — a bathroom twice as big does not cost twice as much because the fixed items (permit, mobilization, plumbing rough-in, waterproofing detail) stay constant.
15–25 sq ft
$6,000 – $15,000
Vanity, toilet, floor, paint, lighting, mirror. No shower or tub = no waterproofing complexity.
- Budget refresh: $6,000–$8,000
- Mid-range: $8,000–$12,000 (tile floor, semi-custom vanity, statement mirror)
- High-end: $12,000–$15,000 (custom vanity, wallpaper, premium fixtures)
- Typical timeline: 1–2 weeks on-site
- Permit required only if plumbing or electrical relocates
35–50 sq ft
$12,000 – $45,000
Tub-shower combo or converted walk-in, single vanity, toilet, tile. Idaho's most common remodel.
- Refresh, same layout: $12,000–$22,000 (new tile, vanity, toilet, fixtures, paint and lighting — plumbing stays put)
- Full remodel: $25,000–$45,000 (full demo, tiled walk-in shower with frameless glass, new vanity and top, tile or LVP floor)
- Typical timeline: 2–4 weeks on-site
- Building + plumbing + electrical permits required in most Idaho jurisdictions
60–120 sq ft
$25,000 – $95,000
Dual vanity, walk-in or curbless shower, freestanding tub, layout changes, premium finishes.
- Full remodel: $25,000–$45,000 (full demo, tiled walk-in shower, frameless glass, new vanity and top)
- Luxury suite: $55,000–$95,000 (curbless or custom shower with niches and a bench, freestanding tub, custom double vanity, heated tile floors)
- Typical timeline: 4–8 weeks on-site depending on structural scope
- Full permit set including plan review if walls move
Figures reflect Iron Crest's recent 2026 Treasure Valley estimate portfolio. Regional variance section below.
A bathroom is not one job. It is six to eight specialized trades working in sequence, each pulling separate permits where required. Understanding the split protects you from the two most common estimate problems: a padded labor line, or a missing waterproofing line.
| Component | Typical Share | Dollar Range | Notes |
|---|---|---|---|
| Demolition | 2–5% of budget | $800 – $2,500 | Tub, tile, drywall, vanity, flooring, and haul-away. Pre-1985 homes may need asbestos test ($200–$500) and abatement ($1,500–$4,000) before demo can proceed. |
| Rough plumbing | 6–12% of budget | $1,500 – $4,500 | Licensed Idaho plumber reconfigures supply, drain, and venting. Same-footprint fixture swap lands at the low end; relocating a shower or moving the toilet lands at the high end. |
| Rough electrical | 3–7% of budget | $800 – $2,500 | GFCI outlets, exhaust fan wiring, lighting circuits, heated floor circuit. Older Boise homes with shared bathroom-bedroom circuits need code upgrade to dedicated bathroom circuit. |
| Framing / structural | 2–5% of budget | $500 – $2,000 | Wall repair or modification, subfloor reinforcement for tile, blocking for grab bars, curbless shower framing. Load-bearing wall removal adds $2,000–$8,000 including engineering. |
| Waterproofing + cement board | 3–6% of budget | $1,000 – $3,000 | Schluter KERDI, Wedi, or equivalent bonded waterproofing membrane. Non-negotiable for a bathroom that lasts 20+ years without mold behind the walls. |
| Tile installation (labor) | 10–20% of budget | $2,500 – $6,000 | $8–$18 per square foot for skilled Treasure Valley tile labor. Shower surround with niche and bench, plus floor, is the typical scope. Complex patterns and mosaic accents run higher. |
| Vanity + countertop | 8–20% of budget | $1,500 – $8,000 | Stock vanity + cultured marble top $600–$1,500. Semi-custom vanity + quartz $2,500–$5,000. Custom vanity + slab quartzite $5,000–$8,000+. Idaho's hard water makes quartz the sweet spot. |
| Shower or tub + fixtures | 8–15% of budget | $1,500 – $6,000 | Stock alcove tub + shower head $800–$1,800. Custom-tile shower with premium valve, rain head, hand shower, and body sprays $3,500–$6,000. Freestanding tub $1,200–$5,000+. |
| Toilet + accessories | 2–4% of budget | $400 – $1,500 | Standard elongated $400–$800. Comfort-height with soft-close $700–$1,200. Wall-hung or bidet-integrated $1,200–$1,500+. |
| Flooring | 3–7% of budget | $800 – $3,500 | Porcelain tile $5–$10/sf material + $8–$14/sf install. Heated floor add: $400–$800 in materials for a standard bathroom, plus install. |
| Paint, trim, finish | 2–4% of budget | $500 – $1,500 | Mildew-resistant paint, new baseboards and door casing, hardware, mirror, towel bars, robe hooks. |
| Permits + inspections | 1–3% of budget | $400 – $1,200 | Building + plumbing + electrical + mechanical sub-permits. Plan review $150–$400 if structural. Cosmetic-only work pays $0. |
| Design + project management | 3–5% of budget | $1,000 – $3,500 | Built into the project price on Iron Crest projects. Design fees run higher on premium tiers with heavy selection support. |
| Contingency | 10–15% of budget | $1,500 – $8,000+ | Held for hidden conditions — rotted subfloor, galvanized drain, polybutylene supply, asbestos, undersized joists. 15% recommended for pre-1985 Idaho homes. Unused contingency stays with you. |
Idaho hard water is a real design input.
Treasure Valley water tests moderately hard at most Suez and Veolia service areas. Quartz counters (rather than polished marble or unsealed granite) and ceramic or porcelain tile (rather than natural stone in wet areas) hold up better against mineral deposits. This affects material selection more than budget total, but the wrong material choice costs 5–7 years later.
Idaho is not a single housing market. Labor rates, supplier networks, and permit fee schedules differ by region. Here is what we can tell you honestly about each — including where we do not have first-hand pricing data to publish.
Treasure Valley (Boise metro)
Ada, Canyon, Gem
Iron Crest's home market — figures above reflect verified 2026 estimates.
Boise, Meridian, Eagle, Nampa, Caldwell, Kuna, Middleton, Emmett, and Star draw from the same regional tile, fixture, and plumbing supplier network. Cabinet vanity lead times are typically 4–8 weeks for semi-custom. Skilled tile setter labor stays booked 3–6 weeks out during peak season (April–October).
Iron Crest works this market — figures above are verified.
Magic Valley
Twin Falls, Jerome, Gooding
Similar to Treasure Valley base pricing; freight adders for premium tile and vanity orders shipped from Boise.
Twin Falls and Jerome have local tile and plumbing supply but a thinner high-end fixture ecosystem. Custom shower glass may need to travel from Boise. Iron Crest does not work this market — verify a local Idaho-registered contractor at ibol.idaho.gov before signing.

East Idaho
Bonneville, Bannock, Bingham, Madison
Historically indexes at or slightly below Treasure Valley for labor; supplier ecosystem centered in Idaho Falls.
Idaho Falls, Pocatello, Rexburg, and Blackfoot have their own established remodeling contractor pool with strong local tile and vanity dealers. Iron Crest does not work East Idaho — the figures above apply to Boise metro; use them as a directional reference and confirm with a local contractor.
Iron Crest does not work this market. Verify a local Idaho-registered contractor at ibol.idaho.gov before signing.
North Idaho
Kootenai, Bonner, Boundary, Shoshone
Typically indexes higher than the Treasure Valley — Coeur d'Alene market draws from Spokane suppliers and labor.
Coeur d'Alene, Post Falls, Sandpoint, and Bonners Ferry price closer to Spokane, WA than to Boise. Custom shower glass, premium vanities, and skilled tile labor cost more; luxury build volume from lakefront homes supports better material availability. Iron Crest does not work North Idaho — a local Coeur d'Alene bid from an Idaho-registered contractor is the accurate number.

Recovery percentages from Remodeling magazine's 2024 Cost vs. Value Report — national averages. Idaho does not have a published, city-level dataset for bathroom remodel recovery that we can cite. Ask a local agent what they see on comparable listings in your market.
| Scope | Typical Cost | Recovered at Sale |
|---|---|---|
| Mid-range bathroom remodel (national standard scope) | ~$27,000 | Roughly three-quarters recovered — CvV 2024 mid-range bathroom ≈74% national average. |
| Universal-design bathroom (curbless, grab-bar-ready, no-step) | ~$40,000 | Just over half recovered on paper — CvV 2024 universal design ≈55% — but ages you in place, which has a real utility value the CvV number does not capture. |
| Upscale bathroom remodel (freestanding tub, custom shower, premium finishes) | ~$85,000 | Under half recovered — CvV 2024 upscale bathroom ≈45% national average. |
The highest-ROI bathroom move statewide is the mid-range refresh in a standard full-bath that already has a working layout: new tile surround, quartz vanity top, semi-custom vanity, updated fixtures, no plumbing relocation. That's where the recovery percentage lands closest to the mid-range 74% national figure.
The questions Idaho homeowners ask most about bathroom remodel cost. Every answer draws from Iron Crest's own Treasure Valley scoping and estimate work or from a primary-source figure cited in-line.
How much does a bathroom remodel cost in Idaho in 2026?
In the Treasure Valley in 2026, a bathroom remodel falls into three size bands. A powder room or half-bath remodel runs $6,000–$15,000 (vanity, toilet, flooring, paint, lighting — no shower or tub, so no waterproofing complexity). A standard full-bath remodel runs $12,000–$22,000 as a same-layout refresh and $25,000–$45,000 as a full remodel (tub-shower combo or converted walk-in, single vanity, toilet, tile). A primary suite remodel runs $25,000–$45,000 for a full remodel and $55,000–$95,000 at the luxury end (dual vanity, curbless or custom shower, freestanding tub, heated floors, premium finishes). Iron Crest's typical tub-to-shower conversion as a standalone project runs $6,000–$15,000; tiled upgrades with bonded waterproofing, frameless glass, or curbless entry run above that range. These figures reflect Iron Crest's own recent Treasure Valley estimates; markets outside Boise (Coeur d'Alene, Idaho Falls, Twin Falls) can index differently — verify with a local Idaho-registered contractor.
Why does bathroom cost per square foot look so high compared to a kitchen?
Because a bathroom's cost is dominated by fixed items that exist regardless of the room's size — toilet, vanity, shower or tub, exhaust fan, waterproofing, drain and supply connections, permit, and inspection cycles. A 25-square-foot powder room and a 60-square-foot guest bath both need one toilet, one vanity, one lighting circuit, and one plumbing rough-in. Dividing a largely fixed cost by a small denominator produces a high per-square-foot figure that is technically correct but not useful for budgeting. The more reliable way to budget an Idaho bathroom is to count the items — fixtures, trade connections, surfaces — rather than measure the floor.
What's the biggest cost in a bathroom remodel?
Labor, at 40–50% of the total project. A bathroom is not one job; it is six to eight specialized trades working in sequence: demolition, rough plumbing, rough electrical, framing, waterproofing, tile setting, finish plumbing and electrical, then paint and trim. In Idaho, plumbing is a state-licensed trade (Idaho Code § 54-2601) and must be performed by or under the supervision of a licensed plumber; electrical is licensed under Idaho Code § 54-1001. That's why a bathroom's labor share exceeds a kitchen's: more trades pulling separate permits, more waterproofing detail work, and the tile setter alone runs $8–$18/sf in the Treasure Valley for skilled labor. Materials are 15–20%, fixtures 15–25%, permits 1–3%, design 3–5%, contingency 10–15%.
How much does a tub-to-shower conversion cost in Idaho?
Iron Crest's typical same-footprint tub-to-shower conversion — remove the tub, waterproof the new shower, install a shower pan, install fixtures, install a glass enclosure — runs $6,000–$15,000 in the Treasure Valley, depending on tile selection, glass type, and whether plumbing needs to be relocated. A simple ceramic or basic porcelain tile surround with a stock shower pan and semi-frameless glass sits at the upper end of that range. Upgrades above the typical range add a full waterproofed system (Schluter KERDI or Wedi), premium porcelain or natural stone tile, custom niche, bench, curbless or low-curb entry, and a frameless glass enclosure. Expanding the shower into adjacent space (a closet, a soaker-tub deck you're removing) adds $2,000–$6,000 for framing, drywall, and additional tile. Iron Crest handles tub-to-shower conversions across the Treasure Valley with a written scope and 1-year workmanship warranty.
How much do bathroom permits cost in Idaho?
For a typical $25,000–$45,000 bathroom remodel in the City of Boise, expect $300–$700 for the building permit itself, $75–$200 for the plumbing permit, $75–$150 for the electrical permit, $50–$100 for the mechanical permit if a new exhaust fan vents to the exterior, and $150–$400 for plan review if the project involves structural changes (removing walls, moving plumbing stacks). Total permit and inspection cost lands in the $400–$1,200 range for most bathroom projects. Meridian, Nampa, Caldwell, and Eagle each publish separate fee schedules. Purely cosmetic work — swapping a faucet, replacing a toilet at the same rough-in, repainting — does not require a permit. Confirm current fees at the time of application; fee schedules update.
What's the return on investment for a bathroom remodel in Idaho?
Remodeling magazine's 2024 Cost vs. Value Report puts a mid-range bathroom remodel at about 74% of cost recouped nationally, a universal-design bathroom (aging-in-place scope) at about 55%, and an upscale bathroom remodel at about 45%. Those are national averages, not Idaho-specific. Idaho does not have a published, city-level dataset for bathroom remodel recovery that we can cite. Ask a local agent what they see on comparable listings in your specific market — Boise Bench vs. Meridian vs. Coeur d'Alene will look different. The highest-ROI move statewide is the mid-range refresh in a standard full-bath that already has a working layout: new tile surround, quartz vanity top, semi-custom vanity, updated fixtures, no plumbing relocation.
Do I need to keep at least one bathtub in the house?
For resale, yes — keep at least one tub, especially if the home has bedrooms sized for children. Homes with zero bathtubs are harder to sell in Idaho's family market. The tub does not have to be in the primary suite. Most homeowners converting to walk-in showers in Idaho are doing it in the primary bathroom while leaving the tub-shower combo in the guest or hall bath intact, which preserves resale flexibility while giving the daily-use bathroom a modern layout. If your home already has only one bathroom, we would not typically recommend removing the tub — accessibility and resale both push toward keeping it, or replacing it with a tub-shower combo rather than a shower-only setup.
How long does a bathroom remodel take in Idaho?
On-site construction for a standard full-bath remodel is typically 2–4 weeks. A powder room or half-bath runs 1–2 weeks. A primary suite with layout changes and structural work runs 4–8 weeks. Add design and permitting on the front end: 3–6 weeks for design and material selection, plus 1–3 weeks for permit issuance in the Treasure Valley (longer during spring/summer peak). Cabinet or vanity lead times can be 4–10 weeks for semi-custom orders. From first meeting to finished bathroom, a typical Idaho project runs 10–16 weeks. We do not begin demolition until every material is confirmed and on-site or en route — this prevents the two most common timeline killers: back-ordered vanity tops and mis-sized shower glass.
What hidden costs should I budget for in an older Idaho home?
In pre-1985 Idaho homes, budget a 15% contingency (vs. 10% on newer builds). The five most common surprises: (1) rotted subfloor around the toilet or shower — $500–$2,500 to repair; (2) galvanized steel drain lines that need replacement with ABS or PVC — $1,000–$3,500; (3) polybutylene supply pipes (common in 1980s Idaho homes) that must be replaced with PEX or copper — $500–$2,000; (4) electrical code upgrades: GFCI protection, dedicated circuits, proper exhaust fan wiring — $500–$2,000; (5) asbestos in 9x9 vinyl floor tiles or drywall joint compound in pre-1985 homes — testing $200–$500, licensed abatement $1,500–$4,000 per Idaho DEQ regulations. If nothing turns up, the contingency stays with you.
Should I remodel the primary bath and the guest bath at the same time?
Often yes, if both need work — the mobilization, permit, and trade scheduling efficiencies typically save 8–15% versus running two separate projects a year apart. The catch is the household disruption: two bathrooms out of service at once means using the powder room or a temporary shower setup for the duration. In a two-bathroom home, we would generally advise sequencing (primary first, guest bath 4–8 weeks later) rather than concurrent. In a three-bathroom-plus home, concurrent is usually the right call. The written scope treats them as one project with separate line items so you can see exactly what each bathroom contributes to the total.
