Permit costs and review times in Kuna
Permit fees and plan-review turnaround are set by Kuna, not by the contractor, and they differ across the Treasure Valley. They belong in your budget and your schedule from the start.
- How Kuna calculates the fee
- Valuation-based project-value table plus a $70 residential building-permit submittal fee. Example tiers: $25,001–$50,000 adds $7.20 per additional $1,000; $50,001–$100,000 adds $5.15 per $1,000. Residential structural plan review is $65 per hour (1-hour minimum).
- Plan-review turnaround
- Kuna does not publish a turnaround time. Confirm the current wait with the department before committing to a schedule.

Idaho adopts building codes by statute, so the code editions are the same statewide — the 2018 IRC with Idaho amendments and the 2023 NEC. What changes between cities is the fee formula, the review queue, and which office holds the file.
The cost of shower remodeling in Kuna depends on the scope of work, materials selected, complexity of the layout, condition of existing systems, and the finish level you choose. Every project is different, but understanding the major cost drivers helps you plan a realistic budget and make informed decisions about where to invest and where to save. The ranges above reflect the full spectrum of projects we complete in Kuna — from straightforward updates to comprehensive renovations with premium materials and significant structural changes.
Actual project scenarios we complete in Kuna, with the typical investment and timeline for each:
Kuna Ranch or Older Home — Tub Module to Walk-In Shower
$9,000–$14,0007–10 business daysOlder Kuna homes with original or replacement fiberglass tub modules are the most common shower remodel canvas in the city's pre-2000 housing stock. Full demolition, substrate inspection and repair, KERDI waterproofing, 12x24 porcelain tile walls, pre-sloped foam shower floor with center drain, single niche, new shower valve and fixtures, and semi-frameless or frameless glass enclosure transforms these bathrooms efficiently and affordably. The result is a shower that works properly, looks current, and requires only ordinary maintenance — exactly what busy Kuna families need.
Quenzer Farms or Crimson Point — Builder Module Upgrade
$10,000–$15,5007–11 business daysKuna's newer production subdivisions feature the same builder-grade fiberglass modules as the rest of the Treasure Valley, and their owners are beginning the same upgrade conversation as Meridian and Nampa homeowners five years ahead of them. These module replacements are technically straightforward — the substrate is newer, the subfloor conditions are generally better — and the scope follows Iron Crest's proven process: module removal, substrate check, KERDI, tile, and glass. The upgrade from module to custom tile is visually dramatic regardless of the home's age.
Accessible Family Shower for Multi-Generational Kuna Households
$9,500–$15,0007–11 business daysKuna's strong family culture means that multi-generational living — grandparents in the home or nearby, visiting family who needs accessible facilities — is a genuine driver of accessible shower design. Zero-threshold entries, built-in bench seating, grab bar blocking installed during the waterproofing phase, handheld showerheads on slide bars, and wider glass opening configurations make a shower safe and comfortable for household members of all ages and mobility levels. Iron Crest installs grab bar blocking as a standard included detail on every Kuna shower project, at minimal additional cost.
Secondary Bathroom Re-Waterproof for Family Daily Use
$7,500–$11,5005–8 business daysIn households with multiple children, secondary bathroom showers take more daily use than any other fixture in the home. Failing grout, repeated caulk applications, and the musty odor that signals hidden moisture damage are signs that the secondary bath needs the same quality waterproofing and tile treatment as the primary. These projects are sized for value — 12x24 tile, semi-frameless glass, KERDI waterproofing — but executed to the same structural standard as a primary suite installation.
These are the factors that have the biggest impact on your shower remodel budget in Kuna. Understanding each one helps you make better decisions during the planning phase.
Shower Size and Configuration
high impactA standard 3x4 foot shower costs significantly less than a 4x6 or 5x8 foot walk-in. Larger showers require more tile, more waterproofing, larger glass enclosures, and more labor.
Tile Selection and Design Complexity
high impactStandard subway tile on walls with mosaic floor tile is the most affordable option. Large-format tiles, natural stone, intricate mosaic patterns, accent bands, and niche detailing increase material and labor costs significantly.
Plumbing Modifications
medium impactKeeping the drain and supply lines in their existing locations is the most affordable approach. Moving the drain, adding supply lines for multiple showerheads, or converting from a tub configuration adds plumbing labor and material cost.
Glass Enclosure Type
medium impactA shower curtain is the least expensive enclosure. Semi-frameless glass doors run $800-1,500. Frameless glass enclosures with custom panels range from $1,200-3,500+ depending on size and configuration.
Accessibility Features
medium impactZero-threshold entries with linear drains, built-in bench seating, grab bar blocking, and anti-slip flooring add cost but provide essential function for aging-in-place planning.
Fixture Quality
low impactBuilder-grade showerheads and valves start around $150-300. Mid-range fixtures from Delta, Moen, or Kohler run $400-800. Premium thermostatic systems with rain heads and body sprays can exceed $2,000.

Shower Remodeling in Kuna: housing stock, climate & permits →How much does a shower remodel cost in Boise?
A shower remodel in the Boise area typically costs $6,000-12,000 for a standard tub-to-shower conversion with tile, $10,000-18,000 for a mid-range custom walk-in shower, and $18,000-30,000+ for a luxury shower with premium tile, frameless glass, and multi-head fixtures.
What tile is best for shower floors?
Small mosaic tiles (2x2 or penny rounds) are the traditional choice because they conform to the shower pan slope and provide grip with many grout lines. Large-format tiles with linear drains are increasingly popular for a modern, seamless look but require precise slope and installation.
