Typical range in Star: $9,000 – $32,000
Most Star projects: $15,500
Star shower remodel costs reflect the city's newer construction vintage, the design expectations of its homeowner demographic, and Ada County labor and material pricing. A basic tub-to-walk-in-shower conversion in a Star production home — fiberglass module removal, substrate inspection, Schluter KERDI waterproofing, 12x24 porcelain tile walls and floor, semi-frameless glass enclosure, and plumbing modifications — typically runs $9,000 to $14,000. A mid-range project with large-format 24x24 or 24x48 tile, built-in niche, frameless glass enclosure, thermostatic valve, and quality fixtures runs $14,000 to $21,000. Full primary suite bathroom gut remodels combining shower, vanity, and flooring work range from $21,000 to $32,000. Substrate remediation in Star's production homes is less common than in older Caldwell or downtown Nampa homes, but OSB subfloor delamination under fiberglass modules with cracked bases is a contingency that should be budgeted at $800 to $2,500 for homes built before 2012. Ada County permit fees through the City of Star Building Department run $150 to $400 for residential plumbing permits.
Permit costs and review times in Star
Permit fees and plan-review turnaround are set by Star, not by the contractor, and they differ across the Treasure Valley. They belong in your budget and your schedule from the start.
- How Star calculates the fee
- A non-refundable residential application submittal fee of $100 applies (credited toward the permit). The building-permit fee rate table is published as an image on the city's fee page (linked) — confirm the current rates there.
- Plan-review turnaround
- Small residential projects: 2–4 weeks. Larger residential projects: approximately 4–6 weeks. Each required revision can add ~3–4 weeks.

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 Star 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 Star — from straightforward updates to comprehensive renovations with premium materials and significant structural changes.
Actual project scenarios we complete in Star, with the typical investment and timeline for each:
Star Production Home — Builder Shower to Custom Walk-In Conversion
$10,500–$16,5008–12 business daysThe most common and most emotionally rewarding shower project in Star is the conversion of an original builder-grade fiberglass module or acrylic tub surround to a custom walk-in shower in a home built between 2005 and 2018. The scope: remove the existing module, assess the subfloor and framing, install KERDI waterproofing on all new cement board surfaces, install a pre-sloped foam shower floor system, tile walls with large-format porcelain in the homeowner's selected pattern and color, tile the floor with mosaic or a contrasting large-format tile, add a built-in niche, plumb a thermostatic shower valve with rain showerhead and hand shower, and install a custom-fabricated frameless glass enclosure. The homeowner's design choices — tile format, color, niche configuration, hardware finish, glass panel layout — make every project distinctive. The result is a shower that the homeowners feel genuine pride in every morning, in a home that now feels completely theirs.
The Lakes Neighborhood — Premium Primary Suite Shower Upgrade
$18,000–$32,00012–18 business daysThe Lakes homes in Star sit at the top of the city's shower remodel market, where the combination of larger home values, more generously proportioned primary suite bathrooms, and homeowners with elevated finish expectations creates demand for the same quality tier of shower work that defines Boise's Harris Ranch market. These projects feature: 24x48 large-format rectified porcelain on shower walls in a stone-look veined pattern; a linear drain with a tile-insert cover that maintains a continuous floor plane; built-in bench with a coordinating tile surface; full-height frameless glass enclosure with premium hardware; and a thermostatic shower valve system with ceiling rain head, wall-mounted body sprays, and hand shower on a slide bar. These specifications require execution quality that is meaningfully higher than a basic production home conversion — large-format tile installation demands substrate preparation to ANSI A108.02 tolerances, the linear drain floor requires a precisely sloped foam system, and the frameless glass installation requires precision that the glass fabricator achieves only after templating the actual finished opening.
Downtown Star Historic Property — Original Bath Renovation
$9,500–$15,0008–12 business daysDowntown Star's older corridors contain homes built between the 1930s and the 1970s whose bathrooms have never been substantially updated. These projects require the careful approach that age demands: thorough demolition to assess original construction conditions, attention to the home's architectural character in tile selection, and management of the structural discoveries that opening walls in older construction almost always produces. Original tile in good condition may be preservable in specific elements; more often the mortar bed and substrate behind 50-to-80-year-old tile installations have been compromised by decades of moisture exposure and require complete removal and replacement. KERDI waterproofing over new cement board, followed by a tile selection appropriate to the home's era — clean subway tile, handmade-look ceramic, hex mosaic floor — produces a shower that honors the home's character while performing to a modern waterproofing standard.
Star Family Home — Secondary Bathroom Shower Update
$7,500–$12,0006–9 business daysSecondary bathrooms in Star homes — the hall bath, the kids' bathroom, the guest bath — benefit from the same waterproofing rigor and quality tile work as a primary suite shower at a reduced overall investment. These projects typically involve re-tiling the shower surround over a new KERDI waterproofing layer, replacing the shower valve and fixtures, and refreshing the glass enclosure with a new semi-frameless door. Tile selections for secondary bathrooms lean practical: 4x12 subway tile in a clean white, a 2x2 mosaic floor, and minimal or no decorative accent. The result looks clean, current, and well-made without consuming the renovation budget that the primary suite deserves. In a Star home with young children, a secondary bathroom that is properly waterproofed and easy to clean is a genuine quality-of-life upgrade for the family members who use it every day.
Star Home with Accessible Shower Design
$10,000–$16,5008–12 business daysStar's growing community of families building long-term roots includes homeowners who are planning for lifetime occupancy and want their primary suite shower to serve them well across the full arc of home ownership. Zero-threshold entries, built-in bench at the correct accessible height (17 to 19 inches), blocking installed in the walls at the KERDI waterproofing phase for future grab bar addition, handheld showerhead on a slide bar, and non-slip floor tile are the design elements that make a Star shower genuinely accessible — not as an afterthought accommodation but as a well-designed feature that serves the homeowner today and for the next 30 years of occupancy. Iron Crest builds blocking for future grab bars into every Star shower project as a standard included detail, because the cost of retrofitting blocking after tile is installed exceeds the cost of including it at construction.
These are the factors that have the biggest impact on your shower remodel budget in Star. 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 Star: 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.
