Shower Contractor in Kuna, Idaho
Licensed shower contractor for Kuna homeowners — builder upgrades, tub-to-shower conversions, Schluter waterproofing, heated floors, and frameless glass built to last
Kuna has grown rapidly from a small agricultural community into one of Ada County's most family-friendly residential areas. Homes here are predominantly built after 2005, with builder-grade bathrooms that function but do not match the quality expectations of homeowners who have now lived in their homes for five to fifteen years and are ready to personalize them.
The primary bathroom shower is consistently at the top of Kuna homeowners' remodel priority lists. Builder fiberglass units discolor and develop caulk failures. Basic ceramic tile grouts stain and become impossible to clean back to new condition. And the tub that came standard in the primary bathroom alcove — rarely if ever used by any adult in the home — occupies space that could be a proper walk-in shower that actually gets used every day.
Iron Crest builds shower remodels in Kuna that families use for decades. Schluter KERDI waterproofing on every shower, permits through the City of Kuna, and a 5-year workmanship warranty. Idaho RCE License #6681702.
Tub-to-Shower Conversion
Remove the builder tub from the primary bathroom alcove and build a walk-in tile shower in its place. The most requested shower project in Kuna. Works within the existing alcove footprint in most homes. Schluter KERDI waterproofing, porcelain tile, frameless glass panel or door. $5,000–$12,500.
Fiberglass Surround Replacement
Remove the builder one-piece or three-piece fiberglass unit and replace with custom tile on Schluter KERDI. Transforms the visual quality of the primary bathroom permanently. The fiberglass can never be restored to new condition — replacement is the only way forward.
Walk-In Shower with Heated Floor
Custom walk-in shower with electric heated floor mat, large-format porcelain, frameless glass enclosure, built-in niche, and quality fixtures. The complete primary bathroom shower upgrade for Kuna homeowners ready to invest in the room they use every morning.
Curbless Accessible Shower
Zero-threshold entry with linear drain, grab bar blocking, optional bench, and handheld showerhead. ADA-compatible design for families accommodating all ages and mobility levels in Kuna homes.
Kuna's newer housing stock does not guarantee proper shower waterproofing. Builder-grade shower installations were constructed during rapid tract construction with cost-efficiency as the primary driver — not long-term performance. When we open Kuna shower walls that are 8–12 years old, we consistently find either:
Fiberglass units with caulk failures at the flange, allowing moisture to wick into the wall cavity behind the unit over years of use
Ceramic tile installed over cement board without a bonded waterproofing membrane, where grout failure has allowed moisture infiltration
Failed caulk at the tub-to-tile transition that allowed water to run behind the tub lip for years without visible symptoms
Iron Crest installs Schluter KERDI on every Kuna shower — new or old — because we build showers that perform for 20–30 years, not showers that look fine for the first 5 years and then require expensive remediation.
Kuna's family-focused community includes homeowners at every stage of life — from young families with children to established homeowners planning for long-term livability. Iron Crest builds accessible shower features into Kuna remodels that add value now and support long-term use:
Grab bar blocking — the single most cost-effective accessibility feature — is installed in all shower walls during construction at almost no incremental cost. It allows grab bars to be added at any future point without opening tile or walls. Iron Crest installs blocking as a standard item on every Kuna shower we build, whether accessibility features are requested now or not.

Existing shower or tub demolished to studs and subfloor. Kuna's newer homes typically have sound framing and subfloors — we confirm and document any conditions requiring remediation before proceeding.
Schluter Waterproofing Installation
Cement board or Kerdi-Board installed on walls and floor. KERDI membrane fully bonded with KERDI-Band at all seams, corners, and penetrations. Heated floor mat installed if specified. Schluter drain connected with KERDI-Seal gasket. All work inspected before tile begins.
Tile, Glass, Fixtures, and Final Walkthrough
Tile set on walls and floor with proper mortar, cure, and grout sequence. Frameless glass measured and installed after tile cures. Fixtures and controls installed and tested. City of Kuna final inspection passed. We walk every inch with you before project completion.
The following government agencies, industry organizations, and official resources provide additional information relevant to your remodeling project.
What does a tub-to-shower conversion cost in Kuna, Idaho?
A tub-to-shower conversion in a standard Kuna home alcove typically runs $5,000–$12,500. Most Kuna homes were built after 2005, which means predictable infrastructure — modern plumbing rough-in, newer subfloors, and standard alcove dimensions — that keeps costs more predictable than older construction. The primary cost variables are tile selection, whether a frameless glass door or panel is included, and whether a heated floor is added. A straightforward conversion with standard porcelain and a frameless panel typically comes in at $6,000–$8,500. A larger scope with large-format tile, built-in niche, and a frameless hinged door runs $9,000–$13,000. Iron Crest provides fully itemized estimates before any work begins.
What shower upgrades are most popular with Kuna families?
Kuna's family-oriented communities — many with young families in homes purchased in the past five to ten years — tend to focus shower remodels on durability, ease of maintenance, and converting underused tubs to functional walk-in showers. The most popular upgrades include: tub-to-shower conversions in primary bathrooms (the tub is rarely used once children are past bath age), builder fiberglass surround replacement with custom tile that is easier to clean and looks significantly better, heated shower floors for cold Kuna winters, and built-in tile niches that eliminate shower caddies and soap dishes. Kuna homeowners consistently tell us the shower remodel is the single bathroom improvement that changes how they feel about starting the day.
Does waterproofing matter in newer Kuna homes?
Yes — absolutely. Builder-grade shower surrounds in Kuna's newer homes were installed as cost-efficiently as possible during construction. Many of these installations used fiberglass units or basic ceramic tile over cement board without a bonded waterproofing membrane behind the tile. The fiberglass units fail at the caulk lines and at the tub lip; the ceramic tile installations develop grout failure and moisture infiltration within 7–12 years. When Iron Crest demolishes a builder shower in a Kuna home that is 8–12 years old, we regularly find the beginning of moisture damage behind the tile. Schluter KERDI membrane — which we install on every shower regardless of age or budget — eliminates this failure mode by waterproofing the substrate before any tile is set.
How do I replace a builder fiberglass shower in my Kuna home?
Replacing a builder fiberglass surround in a Kuna home is a straightforward process that Iron Crest completes regularly throughout Kuna's subdivisions. We remove the fiberglass unit, inspect the framing and subfloor for any existing moisture damage, make any needed repairs, install cement board or Schluter Kerdi-Board as the substrate, apply the full KERDI waterproofing membrane system, set large-format porcelain tile on walls and appropriate tile on the floor with proper slope, grout, install fixtures, and finish with a frameless glass panel or door. The project requires a plumbing permit from the City of Kuna and typically completes in 7–10 business days from permit issuance.
Do I need permits for a shower remodel in Kuna?
Yes. Shower remodels in Kuna that involve any plumbing modification — including drain relocation, supply line changes, or showerhead valve replacement — require a plumbing permit from the City of Kuna Building Department. Electrical work for heated floors requires an electrical permit. Kuna's building department has processed significant permit volume in recent years as the city has grown rapidly. Permit processing typically takes 1–2 weeks. Iron Crest handles all permit applications for your Kuna shower project — you do not need to navigate the permit process yourself.
What tile options work best for a family shower in Kuna?
Kuna families with children and busy daily schedules benefit from tile choices that minimize maintenance. For shower walls, large-format porcelain (12x24 or 24x24) reduces grout lines — fewer grout joints means less surface for soap scum and mildew to accumulate. Rectified large-format tile with a 1/16-inch grout joint is the easiest shower surface to clean. For shower floors, matte-finish porcelain mosaic (2x2 or 3x3) or 4x4 tiles provide traction on wet floors and the tight grout lines clean well with a brush. Neutral tones — light gray, warm white, or matte off-white — are forgiving of water spots and show soap scum less than darker tiles. Iron Crest brings tile samples to your Kuna home for in-context selection.
Can I add a heated shower floor to my Kuna bathroom remodel?
Yes — heated shower floors are an increasingly popular addition to Kuna shower remodels. Kuna's winters are cold, and stepping onto a heated shower floor before work in the morning consistently ranks as one of the most-appreciated daily home improvements. We install Nuheat or Schluter DITRA-HEAT electric mat systems beneath the shower floor tile, connected to a programmable thermostat outside the shower enclosure. The mat is installed during the tile phase of the shower build. An electrical permit and dedicated circuit are required through the City of Kuna. The addition typically costs $800–$2,000 added to the shower scope.
What ADA or aging-in-place features should Kuna homeowners consider?
Even in new construction, planning for long-term accessibility during a shower remodel is smart. The single most cost-effective accessibility feature is grab bar blocking — solid wood blocking installed between studs in the shower walls during construction, behind waterproofing and tile. This allows grab bars to be installed at any future point without opening the walls. It costs almost nothing during construction and can save thousands in future renovation costs. Other features Iron Crest builds into Kuna showers include: curbless zero-threshold entry with linear drain, fold-down bench, handheld showerhead on adjustable slide bar, and wide entry openings. These features can be incorporated into any Kuna shower remodel without sacrificing design quality or significantly increasing cost.
