From tub-to-shower conversions to luxury walk-in designs with frameless glass, rain showerheads, and built-in niches — we handle every detail from waterproofing to finish hardware.
Star, Idaho is a community of deliberate choices — people who drove past Meridian and Eagle and kept going until they found a town that felt like a place rather than a subdivision. The homes here reflect those choices: newer construction in The Lakes and Dry Creek districts where families are putting down roots, and downtown Star's older corridors where original charm is being paired with modern upgrades. In the primary suite bathroom, that same deliberate sensibility expresses itself clearly: Star homeowners don't want the builder shower their home came with. They want something they chose — a custom tile installation with frameless glass that reflects how they actually live, not what the spec sheet said the house needed to sell. Iron Crest Remodel builds Star showers that deliver on that intention: Schluter Systems waterproofing, large-format tile, and frameless glass done right, for homeowners who moved to Star because they know the difference.
Design and build the shower you have always wanted — from custom tile work to barrier-free walk-ins.

A shower remodel transforms one of the most-used spaces in your home — from a basic, builder-grade enclosure into a custom-designed space that fits your daily routine, aesthetic preferences, and long-term needs. Shower remodeling involves demolition of the existing shower or tub, plumbing rough-in for new drain and supply locations, structural preparation, waterproofing membrane installation, tile or panel application, glass enclosure installation, and fixture mounting. In the Treasure Valley, many homes built in the 1990s and 2000s have small, dark, builder-grade showers with fiberglass surrounds, poor drainage, and inadequate waterproofing that leads to hidden water damage over time. A properly planned shower remodel addresses all of these issues while creating a space that is both beautiful and built to last. The most critical element of any shower build is waterproofing — every surface that receives water must be properly membraned, sealed, and sloped to prevent moisture from reaching the framing and subfloor behind the finished surface.
Star homeowners pursue shower remodeling for a variety of reasons. Here are the most common situations we see:
Not every shower remodel project is the same. Here are the most common project types we complete in Star:

Remove an existing bathtub and replace it with a custom walk-in shower. Includes new drain placement, curb or zero-threshold entry construction, waterproofing, tile installation, glass enclosure, and updated fixtures.

Redesign and rebuild an existing shower with new tile, fixtures, glass enclosure, niches, and lighting. May include expanding the shower footprint, adding a bench, or changing the layout.

Design and build a zero-threshold shower with curbless entry, linear drain, anti-slip tile flooring, grab bars, fold-down bench seating, and handheld showerhead for accessible daily use.

High-end shower build with premium tile, rain showerhead, body sprays, thermostatic valve system, LED lighting, large-format niches, and frameless glass enclosure. Designed for a spa-like daily experience.

Install grout-free solid surface shower panels for a clean, low-maintenance alternative to tile. Ideal for homeowners who want a fresh shower without the upkeep of grout cleaning and sealing.

Star's housing stock is overwhelmingly post-2015 construction. Modern systems throughout, but builder-grade finishes that homeowners customize over time.

Material selection affects the look, durability, and cost of your shower remodel. Here are the most popular options we install in Star:

The most popular shower surface material. Dense, water-resistant, available in hundreds of styles including large-format, wood-look, stone-look, and mosaic options. Large-format tiles (12x24 and up) create a modern, seamless look.
Best for: Shower walls, floors, niches, and accent features

Premium tile option that delivers a luxurious, one-of-a-kind look. Marble hexagon floors, marble slab walls, and travertine accents create a spa-like atmosphere. Requires sealing and careful maintenance.
Best for: Feature walls, luxury shower floors, accent strips, and niche interiors

Bonded waterproofing membrane system applied to every shower surface. Available as sheet membrane, liquid-applied membrane, or foam board panels. The single most critical material in any shower build — it prevents water from reaching the structure.
Best for: Every shower floor, wall, curb, niche, and bench surface — no exceptions

Custom-measured and fabricated clear tempered glass panels and door with minimal hardware for a clean, modern look. Available in 3/8-inch and 1/2-inch glass thicknesses with various hardware finishes.
Best for: Walk-in showers where visual openness and modern design are priorities

Pressure-balancing or thermostatic shower valve with trim, showerhead, and optional handheld sprayer. Quality fixtures from Moen, Delta, Kohler, or Grohe provide reliable temperature control and water delivery.
Best for: Every shower — the valve is the functional heart of the shower system

Here is how a typical shower remodel project works from first contact to final walkthrough:
We visit your bathroom, evaluate the existing shower or tub space, discuss your daily routine and wish list, and review layout options, material choices, and fixture selections. You receive a design concept and detailed estimate.
We finalize the shower layout, tile design, niche locations, fixture selections, glass enclosure style, and any accessibility features. Materials are ordered and lead times are confirmed. A fixed-price contract is prepared.
The existing shower or tub is demolished, and we inspect the framing, subfloor, and drain condition. New plumbing rough-in is completed for the reconfigured drain location, supply lines, and valve placement. Framing modifications for niches, benches, and shower size are completed.
This is the most critical phase. We apply a bonded waterproofing membrane system (Schluter Kerdi, Laticrete Hydro Ban, or equivalent) to every shower surface — floor, walls, curb, niches, and bench. The shower pan is sloped to the drain and tested for leak-proof integrity before tile begins.
Floor tile is installed first with proper slope to drain, followed by wall tile, niche tile, bench tile, and any accent or feature tile. Grout is applied, cleaned, and sealed. Large-format tiles, mosaics, and accent patterns are laid out precisely per the design plan.
The glass enclosure (frameless, semi-frameless, or framed) is measured, fabricated, and installed. Showerhead, valve trim, diverter, handheld sprayer, grab bars, towel hooks, and all hardware are mounted and tested.
We run the shower for an extended test to verify drainage, water pressure, valve operation, and leak-free performance. Grout sealant is applied, and a final walkthrough ensures every detail meets expectations.
Here is what to expect for project duration when planning a shower remodel in Star:
| Phase | Duration | Details |
|---|---|---|
| Design and Material Selection | 1–3 weeks | Consultation, design development, tile and fixture selection, and contract finalization. Material lead times for specialty tile and glass can add 2-4 weeks. |
| Demolition and Plumbing Rough-In | 2–3 days | Remove existing shower or tub, inspect framing and subfloor, complete plumbing rough-in for new drain and supply locations, and frame any niches or benches. |
| Waterproofing | 1–2 days | Apply waterproofing membrane to all shower surfaces. Test the shower pan for leak-proof performance. This phase must be completed and verified before tile begins. |
| Tile Installation | 3–6 days | Floor tile, wall tile, niche tile, and accent tile installation. Grouting and sealing. This is typically the longest phase of active construction. Complex designs take longer. |
| Glass and Fixture Installation | 1–2 days | Glass enclosure measurement, fabrication (if not pre-ordered), and installation. Showerhead, valve trim, hardware, and accessories are mounted and connected. |
| Final Testing and Walkthrough | 1 day | Extended shower test, drainage verification, grout sealing, and homeowner walkthrough to confirm quality and function. |
Star range: $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.
The final cost of your shower remodel in Star depends on several factors. Here are the biggest cost drivers:
A 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.
Standard 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.
Keeping 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.
A 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.
Zero-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.
Builder-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.
These are the real-world projects we see most often from Star homeowners:
The 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 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'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.
Secondary 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'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.

Solution: We demolish to studs, inspect and repair all water-damaged framing and subfloor, and rebuild with a proper waterproofing membrane system that prevents future moisture intrusion.
Solution: We expand the shower footprint where possible, use light-colored large-format tile to open up the space, install a frameless glass enclosure for visual openness, and add recessed LED lighting for a bright, spacious feel.
Solution: We remove the old surround, inspect the substrate, install proper waterproofing, and build a custom tile shower that transforms both the look and feel of the space.
Solution: We evaluate your water supply capacity and install a pressure-balancing or thermostatic valve system with options for rain showerheads, handheld sprayers, and body jets — significantly improving the shower experience.
Solution: We use mold-resistant grout, properly sealed tile joints, and premium silicone caulk at all change-of-plane transitions. A properly waterproofed shower with adequate ventilation prevents mold from developing behind the finished surface.

Here are the design trends we see most often in Star shower remodel projects:
Star's rapid growth and desirable small-town character make updated homes highly sought after. Finish upgrades in Star homes provide strong returns in a competitive resale market. The community continues to attract buyers willing to pay a premium for updated, personalized homes.

Avoid these common pitfalls Star homeowners encounter with shower remodel projects:
Better approach: Builder shower conversions in Star are technically similar to module replacements in Meridian but the design conversation is entirely different. Star homeowners are not primarily solving a structural problem — they are personalizing their space. Approaching the project with a product catalog and standard options is the wrong starting point for a Star homeowner who has been collecting tile inspiration for two years and has clear preferences about format, finish, and hardware. Iron Crest's Star shower process begins with a genuine design discovery conversation that treats the homeowner's aesthetic preferences as the primary design brief, with technical requirements and structural considerations as the framework within which that brief is realized.
Better approach: A pressure-balanced valve in a $16,000 custom tile shower with frameless glass and large-format porcelain is a specification mismatch that Star homeowners notice immediately in daily use. The temperature instability of a pressure-balanced valve — the cold shock when the dishwasher fills, the heat spike when a toilet flushes — undermines the daily experience of a shower that in every other respect performs as intended. The incremental cost of a thermostatic valve upgrade in the context of a $14,000 to $18,000 shower project is $600 to $1,200 — a 5 to 8 percent project cost addition for a daily-use experience improvement that is immediately and consistently appreciated. Iron Crest specifies thermostatic valves as the standard recommendation for all Star primary suite shower projects.
Better approach: Star homeowners sometimes arrive at their first contractor meeting with tile selections already made — a specific tile they fell in love with online or in a showroom. The problem is that tile selection before space planning can produce choices that are visually ideal but technically unsuitable for the specific shower footprint: a 24x48 tile in a 32x32-inch shower where the substrate flatness required by that format cannot be achieved, or a format that requires more cuts per wall face than the budget accommodates. Iron Crest confirms the shower dimensions and space plan before any tile selection is finalized, then evaluates the homeowner's preferred options against the specific technical requirements of the actual project.
Better approach: Frameless glass enclosures must be custom fabricated to the exact dimensions of the finished shower opening after tile is installed — not the rough opening dimensions before tile. Tile thickness plus setting material depth typically reduces the clear opening by 1/2 to 3/4 inch compared to the rough opening, and glass ordered before tile is installed on rough opening dimensions will either need field cutting (which the glass shop charges for) or will require new fabrication. The correct process: complete tile installation and grout cure, template the actual finished opening, submit to the glass fabricator, and schedule installation 1 to 2 weeks after templating. Iron Crest's standard process follows this sequence on every project and produces glass installations that fit precisely without adjustment.
There's no required waiting period, and many Star homeowners choose to remodel the primary suite shower within the first one to three years of ownership — often as part of a broader primary suite personalization that includes flooring, paint, and lighting updates. The practical question is whether the original shower shows any structural failure indicators: soft subfloor near the drain, a cracked module base, caulk failures at the tub perimeter that return within 12 months of repair. If any of these are present, earlier is better because the structural damage progresses as long as the shower is in use. If the shower is structurally intact and the motivation is purely personalization, the timing is entirely the homeowner's preference.
The single most impactful upgrade in a Star builder shower conversion is the combination of large-format tile on the walls and frameless glass on the enclosure. The builder-grade 4x12 subway tile and chrome semi-frameless glass read immediately as production-standard to any visitor; large-format 12x24 or 24x48 porcelain in a stone-look or concrete-look pattern with a frameless glass enclosure reads as custom and expensive regardless of what the tile itself actually cost. If budget allows only one upgrade to the shower system rather than a full conversion, replacing the builder glass enclosure with a custom frameless enclosure provides immediate visual transformation; if a full conversion is underway, prioritize tile format over tile material cost — a large-format porcelain in a quality stone-look at $4/SF looks more impressive than a smaller-format premium tile at $12/SF.
For Star homeowners who use their primary suite shower as their primary daily bathing fixture — which is most of them — the thermostatic valve upgrade is consistently one of the most appreciated features of the completed shower. The ability to set a specific temperature digitally and have the shower reach that temperature before stepping in eliminates the cold-water transition that is the most reliably uncomfortable part of every morning shower. The additional cost over a quality pressure-balanced valve is $600 to $1,800 depending on brand and the number of outlets controlled. For a shower that will be used daily for the next 15-plus years, the quality-of-life return on this investment is genuinely high and is supported by the feedback we consistently receive from Star homeowners in their completed project reviews.
For most Star shower remodels, no — a design-build contractor with strong tile design capability can take a project from first conversation to finished shower without a separate architect or interior designer. Iron Crest's design process begins with a discovery conversation about the homeowner's aesthetic preferences and daily-use priorities, moves to specific material samples and format options, and produces a written project specification before any work begins. For larger scope projects — a full primary suite bathroom gut-remodel with shower, vanity, flooring, and lighting — some homeowners choose to engage an interior designer for the broader design direction before engaging us for execution. This is most common in The Lakes neighborhood projects where the budget and design aspiration are both at the high end. We work efficiently with designer-specified projects and can accommodate designer-specified materials and configurations in our installation scope.
The most requested shower wall tile format in Star's current market is 24x48 large-format porcelain in a stone-look veined pattern — particularly warm-veined, light-background products in the Calacatta or Bianco Carrara aesthetic. These tiles deliver the look of natural marble slabs at a fraction of the material cost, require no sealing, and perform beautifully in Canyon County's hard water environment in a way that actual marble cannot. On shower floors, the 2x4 or 2x6 mosaic in a matching or subtly contrasting neutral is the most common pairing — it provides the slip resistance required for wet floor applications while creating a visual texture that contrasts pleasingly with the continuous large-format wall tile. The 1x1 mosaic that was the default floor tile five years ago has largely been replaced by the larger mosaic formats because the reduced grout joint density is easier to maintain in Ada County's water.
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.
A typical shower remodel takes 2-3 weeks from demolition to completion. Simple tub-to-shower conversions with panel systems can be faster. Complex custom tile showers with specialty glass take longer. Design and material ordering before construction adds 2-4 weeks.
Walk-in showers are preferred for daily use, accessibility, and modern design. However, having at least one bathtub in the home is recommended for families with young children and for resale value. Many homeowners convert a secondary tub to a shower while keeping one tub elsewhere.
Waterproofing. Every square inch of the shower — floor, walls, curb, niches, and bench — must be properly membraned to prevent water from reaching the framing and subfloor. Proper waterproofing prevents leaks, mold, rot, and structural damage that are extremely costly to repair.
Absolutely. Modern accessible shower design uses curbless entries with linear drains, decorative grab bars in matching finishes, teak fold-down benches, and the same premium tile and glass as any custom shower. The result is a beautiful shower that happens to be accessible.
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.
