Bathroom Remodeling in Kuna, ID: Costs, Ideas & Options
From outdated layouts to modern, efficient spaces — we handle design, demolition, plumbing, tile, fixtures, and every detail in between.
Quick answer
Iron Crest Remodeling Group LLC provides bathroom remodeling in Kuna, ID. Most Kuna bathroom remodeling projects cost $12,000 – $65,000. Bathroom remodels in Kuna range from $12,000 for a cosmetic secondary bath refresh to $65,000+ for a full master suite transformation with custom tilework, frameless glass, and freestanding soaking tub.
Bathrooms in Kuna's fast-growing subdivisions were built for occupancy, not for the families that would actually live in them for the next decade. The primary bathroom in a 2012 Kuna subdivision home typically features a basic soaking tub that nobody uses, a 36-inch single vanity in the master suite of a four-bedroom family home, beige ceramic tile that made sense as a neutral choice on a builder's spec sheet and makes no sense as a design statement for the people actually brushing their teeth in it every morning. Kuna's young families have discovered what homeowners across the country already know: a well-executed bathroom remodel delivers daily quality-of-life returns that no other room in the house can match. Iron Crest Remodel brings Treasure Valley expertise to Kuna's unique builder-grade starting point — transforming standard spec bathrooms into spa-caliber personal retreats and high-functioning family bathrooms built to survive the morning rush hour.
Transform your bathroom with a remodeling plan built around function, comfort, and long-term value.
A bathroom remodel can range from a simple fixture and finish update to a complete gut renovation involving new plumbing lines, electrical circuits, waterproofing, tile work, and custom vanity installation. The scope depends on what you want to change — layout, fixtures, storage, accessibility, or all of the above. In the Treasure Valley, bathrooms built before 2000 often have galvanized plumbing, inadequate ventilation, and small footprints that no longer match how families use the space. A well-planned bathroom remodel addresses all of these issues while upgrading to modern materials, efficient fixtures, and a layout that works for daily life. Whether you are converting a tub to a walk-in shower, expanding a cramped primary bath, or fully renovating a hall bathroom, the key is planning every element — plumbing rough-in, waterproofing, tile layout, vanity selection, lighting, ventilation, and finish hardware — before demolition begins.
Kuna homeowners pursue bathroom remodeling for a variety of reasons. Here are the most common situations we see:
- ✓Homeowners with outdated bathrooms built in the 1980s or 1990s that need a full refresh
- ✓Families who need better storage, double vanities, or improved morning-routine flow
- ✓Aging-in-place homeowners who need accessible walk-in showers, grab bars, and barrier-free entries
- ✓Homeowners preparing to sell who want to maximize ROI with an updated primary or guest bathroom
- ✓Anyone dealing with water damage, mold, or failing tile and grout who needs a complete rebuild
Not every bathroom remodel project is the same. Here are the most common project types we complete in Kuna:
Primary Bathroom Remodel
Full renovation of the main bathroom including layout changes, double vanity installation, walk-in shower or freestanding tub, new tile, lighting, and ventilation upgrades. This is the most common high-value bathroom project.
Guest or Hall Bathroom Remodel
Update a secondary bathroom with new fixtures, tile, vanity, and finishes. These projects focus on function and visual refresh without major layout changes.
Tub-to-Shower Conversion
Remove an existing bathtub and replace it with a walk-in shower, including new drain placement, waterproofing, tile or panel walls, glass enclosure, and updated fixtures.
Accessible Bathroom Remodel
Design and build a barrier-free bathroom with zero-threshold shower entry, grab bars, bench seating, anti-slip flooring, and wider doorways for wheelchair or mobility aid access.
Powder Room or Half-Bath Remodel
Refresh a small half-bath with a new vanity, faucet, lighting, mirror, paint, and accent tile or wallcovering. A high-impact upgrade for a modest budget.
Kuna's housing stock is predominantly post-2005 construction with modern systems and builder-grade finishes. Homes are generally 1,500-3,000 square feet with standard suburban layouts.
Pre-2005 (Downtown area)
Kuna's smaller stock of pre-2005 downtown homes runs toward the higher end of the local range. Because these older homes may need system updates alongside the cosmetic work, budgets should account for more than finishes alone.
2005–present (subdivisions)
These subdivision homes — the vast majority in Kuna — need the least structural investment. PEX plumbing, 200-amp panels, and energy-efficient systems are already in place, so the budget goes almost entirely toward upgrading builder-grade finishes.
Common issues in Kuna homes
- •Builder-grade cabinets and countertops ready for upgrade
- •Standard builder lighting that needs improvement
- •Carpet throughout that homeowners want to replace with hard flooring
- •Basic landscaping and outdoor living that needs development
Material selection affects the look, durability, and cost of your bathroom remodel. Here are the most popular options we install in Kuna:
Porcelain Tile
$8–$25 per sq ft installedThe most popular choice for bathroom floors and shower walls. Porcelain is dense, water-resistant, available in hundreds of styles including wood-look and stone-look patterns, and extremely durable in wet environments. Large-format porcelain tiles (12x24 and larger) create a modern, seamless look with fewer grout lines.
Best for: Shower walls, floors, accent features, and niches
Ceramic Tile
$5–$15 per sq ft installedA versatile and budget-friendly tile option for bathroom floors and backsplash areas. Ceramic is slightly softer than porcelain and available in a wide range of sizes, colors, and patterns. It works well for walls and dry-area floors.
Best for: Budget-conscious floor and wall applications
Natural Stone (Marble, Travertine, Slate)
$15–$50+ per sq ft installedNatural stone delivers a premium, one-of-a-kind look. Marble is the classic choice for luxury bathrooms, travertine offers warmth and texture, and slate provides a rugged, natural feel. All natural stone requires sealing and ongoing maintenance.
Best for: Feature walls, shower surrounds, vanity tops, and floor accents
Quartz Vanity Countertop
$50–$120 per sq ft fabricated and installedEngineered quartz is the top choice for bathroom vanity countertops. It is non-porous, stain-resistant, available in a wide range of colors and patterns, and does not require sealing. Quartz resists water spots and soap buildup better than natural stone.
Best for: Vanity countertops, shelving surfaces
Acrylic or Solid Surface Shower Panels
$3,000–$7,000 per shower installedFor homeowners who want a grout-free, low-maintenance shower, solid surface panels provide a smooth, seamless wall system. Available in stone-look patterns, these panels install faster than tile and require minimal upkeep.
Best for: Low-maintenance showers, accessible bathrooms, budget-friendly updates
Here is how a typical bathroom remodel project works from first contact to final walkthrough:
Discovery and Design Consultation
We visit your home, measure the existing bathroom, discuss what is and is not working, review your goals and budget range, and photograph the space. You will receive a preliminary scope outline within a few days that includes layout options, material direction, and a ballpark estimate range.
Design Development and Material Selection
We create a detailed design plan including tile layouts, vanity specifications, fixture selections, lighting placement, and color palette. You select materials from our supplier partners or bring your own. We finalize the scope of work, confirm lead times, and prepare a fixed-price contract.
Permitting and Pre-Construction Planning
If your project involves plumbing relocation, electrical changes, or structural modifications, we pull the required permits through your local jurisdiction. We also coordinate scheduling with our tile installer, plumber, electrician, and glass supplier so every trade is lined up before demolition day.
Demolition and Rough-In
We protect adjacent rooms with dust barriers and floor coverings, then carefully demolish the existing bathroom down to studs and subfloor as needed. Plumbing and electrical rough-in happens next — this is when drain locations, water supply lines, recessed lighting, exhaust fan ducting, and any structural framing changes are completed.
Waterproofing and Substrate Preparation
Every shower and wet area receives a proper waterproofing membrane system — either sheet membrane, liquid-applied membrane, or a foam panel system like Kerdi or GoBoard. We verify proper slope to drain, inspect the substrate for flatness and stability, and prepare all surfaces for tile.
Tile, Vanity, and Fixture Installation
Tile installation begins with floor tile, then shower walls and niches, then any accent features. The vanity is set and plumbed, the mirror and lighting are installed, and all fixtures — faucets, showerhead, toilet, towel bars, and hardware — are connected and tested.
Final Inspection, Punch List, and Walkthrough
We complete a detailed punch list inspection, verify all plumbing and electrical connections, test every fixture, and confirm caulk lines, grout joints, and finish details are clean. A final walkthrough with you ensures everything meets expectations before we consider the project complete.
Here is what to expect for project duration when planning a bathroom remodel in Kuna:
| Phase | Duration | Details |
|---|---|---|
| Design and Planning | 2–4 weeks | Initial consultation, measurements, design development, material selections, and contract finalization. Material lead times (tile, vanity, glass) often extend this phase to 4-6 weeks if custom items are involved. |
| Permitting | 1–3 weeks | Permit application, review, and approval through Ada County or Canyon County. Straightforward projects may clear in a few days; projects with structural changes take longer. |
| Demolition and Rough-In | 3–5 days | Remove existing fixtures, tile, drywall, and subfloor as needed. Complete plumbing and electrical rough-in. Schedule and pass rough inspection. |
| Waterproofing and Tile Installation | 5–10 days | Apply waterproofing membranes, install cement board or backer panels, set tile (floor, walls, shower, niches), grout, and seal. This is typically the longest phase of active work. |
| Fixture and Finish Installation | 3–5 days | Install vanity, countertop, sink, faucet, toilet, mirror, lighting, exhaust fan, glass shower door, towel bars, and all finish hardware. |
| Final Inspection and Walkthrough | 1–2 days | Complete punch list, pass final inspection, and conduct walkthrough with homeowner. Ensure all caulk, grout, and finish details are clean. |
Kuna range: $12,000 – $65,000
Most Kuna projects: $28,000
Bathroom remodels in Kuna range from $12,000 for a cosmetic secondary bath refresh to $65,000+ for a full master suite transformation with custom tilework, frameless glass, and freestanding soaking tub. The most popular Kuna project — converting a builder master bath from soaking tub to large walk-in shower — runs $22,000–$38,000 depending on tile complexity and fixture quality. Secondary bathroom double-vanity additions and tile refreshes typically run $14,000–$22,000. Kuna's newer-construction starting point reduces demo and plumbing surprise costs compared to Eagle's older custom market.
The final cost of your bathroom remodel in Kuna depends on several factors. Here are the biggest cost drivers:
Scope of Layout Changes
high impactMoving plumbing drain locations, relocating fixtures, or expanding the footprint of the bathroom significantly increases cost due to plumbing rough-in, framing, and potential subfloor work.
Tile Selection and Coverage Area
high impactTile is often the single largest material cost in a bathroom remodel. Floor-to-ceiling tile in a large shower, intricate mosaic patterns, or premium natural stone can add thousands to the budget compared to standard subway tile.
Vanity and Countertop Selection
medium impactA stock vanity with a cultured marble top might cost $400-800. A custom or semi-custom vanity with a quartz top, undermount sinks, and soft-close hardware can run $2,000-5,000+.
Fixture and Hardware Quality
medium impactBuilder-grade faucets and showerheads start around $150-300. Mid-range fixtures from brands like Delta, Moen, or Kohler run $400-1,000. Premium or custom fixtures can exceed $2,000.
Plumbing and Electrical Updates
medium impactOlder homes may need updated water supply lines, new drain plumbing, GFCI outlet installation, recessed lighting, or exhaust fan upgrades. These hidden costs are common in pre-2000 homes.
Accessibility Features
low impactZero-threshold shower entries, blocking for grab bars, bench seating, wider doorways, and comfort-height toilets add cost but are increasingly popular for aging-in-place planning.
Permits and Inspections
low impactProjects involving plumbing or electrical changes typically require permits. Permit costs in Ada County range from $75-300 depending on scope, plus inspection scheduling time.
These are the real-world projects we see most often from Kuna homeowners:
Master Bath Soaking Tub to Walk-In Shower Conversion
The definitive Kuna master bathroom project: remove the builder soaking tub and basic 36-inch shower, combine the space into a single large walk-in shower with large-format porcelain tile, a linear drain, frameless glass enclosure, multiple showerheads, and a built-in niche for toiletries. The conversion delivers a shower sized and equipped to match the master suite's ambitions. Most Kuna families completing this project describe it as the single upgrade that most transforms their daily routine.
Double Vanity Addition in Master Bath
Adding a second sink to a master bathroom with a single vanity addresses one of the most common Kuna morning-routine pain points. This project typically involves installing new vanity cabinetry, countertops, sinks, faucets, and a larger mirror or mirror set. In most Kuna homes, adding a second drain requires minimal plumbing relocation. Heated floors added during the project make this one of the most cost-effective ways to add daily luxury to a Kuna master bath.
Secondary Bathroom Complete Refresh
Kuna's three-bedroom secondary bathrooms serving two or three children need durability above all else. This project replaces builder tile in the tub-shower area with large-format porcelain, installs new vanity cabinetry with improved storage (pull-out shelves, deep drawers for kid supplies), adds a new toilet, and installs a proper exhaust fan with humidity sensor. Semi-custom vanity cabinetry sized to match the full wall maximizes storage without requiring any floor plan changes.
Powder Room Transformation
Kuna's half bathrooms are often the home's most-seen space by guests — and the most unchanged from builder spec. A powder room transformation installs a statement vanity, designer plumbing fixtures, a tile or board-and-batten wainscoting treatment, and updated lighting that turns the powder room into a design moment. This is a high-impact, relatively lower-cost project that dramatically improves first impressions for guests and resale buyers alike.
Full Master Bath Gut Remodel
For Kuna homeowners ready to create a genuinely spa-level master bathroom, a complete gut remodel redesigns the entire space from floor framing to fixtures. This includes heated tile floors, a large custom walk-in shower with body sprays and a rain head, a freestanding soaking tub as a design focal point (for those who want one), custom cabinetry with integrated lighting, quartz countertops, and a lighting design that accommodates both morning-routine task lighting and evening ambient warmth. Bluetooth exhaust fans with humidity control complete the smart home integration.
Problem: Outdated layout with wasted space and poor flow
Solution: We redesign the layout to maximize usable floor space, improve traffic flow, and create logical zones for the shower, vanity, and toilet areas.
Problem: Failing tile and grout with water damage behind walls
Solution: We demolish to studs, inspect and repair any water-damaged framing or subfloor, install proper waterproofing, and rebuild with modern materials.
Problem: Inadequate ventilation causing mold and moisture issues
Solution: We install a properly sized exhaust fan ducted to the exterior, with a timer or humidity-sensing switch, to control moisture and prevent mold growth.
Problem: Small or dark bathroom that feels cramped
Solution: Strategic lighting placement, lighter tile and paint colors, glass shower enclosures instead of curtains, and large-format tile with minimal grout lines all help a small bathroom feel larger.
Problem: Accessibility challenges for aging family members
Solution: We design barrier-free shower entries, install grab bars with proper blocking, add bench seating, use anti-slip flooring, and ensure doorways accommodate mobility aids.
Kuna shares the Treasure Valley climate with slightly more open exposure and wind than cities closer to the foothills.
Wind Exposure
More open terrain means higher wind loads on exterior surfaces.
Heat and UV
Standard Treasure Valley UV exposure. Exterior materials need UV resistance.

- EPA Lead Renovation, Repair and Painting (RRP) Program — required certification for work in pre-1978 homes
- ●Tile layout planning — setting a centerline, planning cut tiles, and choosing grout width and color can dramatically change the final look
- ●Niche placement — shower niches should be positioned at a usable height and sized to fit standard bottles; recessed niches need proper waterproofing
- ●Lighting layers — combine overhead recessed lighting with vanity sconces for even, shadow-free illumination; consider a dimmable option for nighttime use
- ●Ventilation sizing — the exhaust fan should be rated for the room's cubic footage; undersized fans are the number one cause of bathroom moisture problems
- ●Storage planning — recessed medicine cabinets, vanity drawer organizers, and built-in niches reduce countertop clutter and improve daily function
- ●Color and finish coordination — select faucet, showerhead, towel bar, and hardware finishes early and keep them consistent throughout the room
Here are the design trends we see most often in Kuna bathroom remodel projects:
- →Family-friendly, durable material choices
- →Modern farmhouse and transitional styles
- →Practical kitchen upgrades with better storage
- →LVP flooring throughout
- →Outdoor living spaces — decks, patios, covered areas
Kuna's rapid growth and family-oriented market make it an excellent place for practical remodeling investments. Updated homes sell quickly in this market, and finish upgrades provide strong returns.
Costs and permit requirements differ by jurisdiction across the Treasure Valley. These guides cover Kuna specifically.
Avoid these common pitfalls Kuna homeowners encounter with bathroom remodel projects:
Mistake: Tiling over the existing builder tile to save demo costs
Better approach: Adding tile over existing tile raises the floor height, creates edge-thickness transitions at doorways, and adds weight to the subfloor — but most importantly, it fails to address any waterproofing deficiencies in the original installation. Demo is worth the cost; it allows inspection of the substrate, proper waterproofing membrane installation, and a clean start that will perform for decades.
Mistake: Installing a 60 CFM exhaust fan in a walk-in shower remodel
Better approach: Builder exhaust fans rated at 50–60 CFM are designed for small bathrooms with enclosed tub-shower combos. A large walk-in shower generates significantly more steam and requires 110–130 CFM exhaust capacity with humidity-sensing controls. Undersized fans allow moisture to accumulate, damaging paint, promoting mold, and defeating the purpose of a premium tile installation.
Mistake: Choosing large-format floor tile for the shower floor
Better approach: 12×24 and 24×24 tiles look stunning on shower walls but cannot accommodate the slope needed to drain water to the floor drain when used on the shower floor. Use 2×2 mosaic tile or purpose-designed shower floor tile in smaller formats that can be set with the required pitch. Linear drains are an exception — they allow larger format tile with a single-plane slope, but they require specific framing support and add cost.
Mistake: Selecting fixtures in different metal finishes without a cohesion plan
Better approach: Builder-grade bathrooms often have mismatched finishes because each fixture was purchased independently at the lowest price point. A remodel is an opportunity to unify all hardware — faucets, shower trim, towel bars, robe hooks, toilet paper holders, and light fixtures — in a single finish family. Matte black, brushed nickel, or brushed gold, applied consistently, elevates the entire room for the same fixture cost as mismatched alternatives.
Mistake: Underestimating storage needs in the secondary bathroom
Better approach: Kuna families with children consistently underestimate how much bathroom storage they need when planning a secondary bath remodel. The number of bath toys, children's toiletries, towels, medicines, and first aid supplies that accumulate in a family bathroom is substantial. Design the vanity cabinetry with a full wall of storage, consider a recessed medicine cabinet, and add a linen nook or tower cabinet if any adjacent wall allows. You will not regret over-building storage capacity.

Is it worth converting the soaking tub in my Kuna master bath to a shower?
Yes — and it is the single most commonly requested master bathroom project we do in Kuna. The math is straightforward: if you use the soaking tub fewer than a few times per year but shower daily, the 30–35 square feet occupied by the tub is dramatically underperforming. Converting that space to a large walk-in shower with a rain head, body sprays, and built-in storage delivers a daily luxury experience that matches how modern families actually use their bathrooms. The conversion typically costs $22,000–$38,000 and consistently recovers value in Kuna's resale market.
How do I add a second sink to my Kuna master bathroom?
Adding a second sink in a Kuna master bath typically involves installing new vanity cabinetry (often replacing the existing single-sink unit with a new 60–72 inch double-sink vanity), running an additional drain line to the existing drain stack (a straightforward task in newer Kuna homes with accessible plumbing), and adding a cold water supply line. Because Kuna homes use PEX plumbing, supply line additions are clean and quick. The full project — cabinetry, countertop, sinks, faucets, and updated mirrors — typically runs $9,000–$16,000.
What tile is best for a family bathroom in Kuna?
For secondary bathrooms seeing daily use from kids, we consistently recommend large-format porcelain tile (12×24 or larger) in a matte finish. Matte finishes hide water spots better than polished tile in a busy family bathroom. Rectified tile with narrow grout joints minimizes the grout surface area that needs cleaning — a practical advantage for busy families. For shower floors, 2×2 mosaic tile provides adequate drainage slope and slip resistance. Avoid natural stone in secondary bathrooms unless you're willing to seal it annually — kids won't.
Do I need a permit for a bathroom remodel in Kuna?
Yes, most bathroom remodels in Kuna require permits. Any plumbing changes (adding a drain, relocating a fixture) require a plumbing permit. Electrical work — adding a circuit for a heated floor, upgrading exhaust fan wiring — requires an electrical permit. General building permits cover structural changes. Iron Crest Remodel pulls all required permits and manages the inspection process as part of every project. Unpermitted bathroom work creates complications when selling a home, so doing it right from the start protects your investment.
How long does a master bathroom remodel take in Kuna?
A master bath soaking tub to walk-in shower conversion typically takes 3–5 weeks. A full gut remodel with custom tilework runs 6–8 weeks. The most variable factor is tile lead time — specialty tile can add 2–4 weeks to project start if it needs to be ordered. We specify materials and place orders before demolition begins to keep your project on schedule and minimize time with a non-functional master bath.
How long does a bathroom remodel usually take?
A typical full bathroom remodel takes 4 to 8 weeks from demolition to completion, depending on scope, material lead times, and inspection scheduling. A straightforward fixture and finish update with no layout changes may take 2 to 3 weeks. Projects involving plumbing relocation, custom tile work, or structural changes take longer.
Do bathroom remodels require permits in Idaho?
Yes, most bathroom remodels that involve plumbing changes, electrical work, or structural modifications require permits in Ada County and Canyon County. A simple cosmetic update — paint, fixtures, and accessories — typically does not. We handle the permit application process and coordinate all required inspections.
What is the most expensive part of a bathroom remodel?
Tile and labor are typically the largest line items, followed by the vanity/countertop combination and plumbing rough-in. If the project involves moving drain locations or expanding the footprint, plumbing and framing costs increase significantly.
Can I keep my existing layout to save money?
Yes. Keeping plumbing fixtures in their current locations avoids the cost of rerouting drain and supply lines. Many homeowners save 15-25% by refreshing finishes, tile, and fixtures without changing the floor plan.
Should I choose a walk-in shower or a bathtub?
It depends on your household needs and resale considerations. Walk-in showers are more popular for primary bathrooms and aging-in-place planning. Having at least one bathtub in the home is generally recommended for families with young children and for resale value.
How do you handle waterproofing?
We use industry-standard waterproofing systems — either sheet membrane (like Schluter Kerdi), liquid-applied membrane, or foam panel systems — on all shower floors, walls, curbs, and niches. Proper waterproofing prevents leaks, mold, and structural damage behind tile.
What tile is best for bathroom floors?
Porcelain tile is the most popular and practical choice for bathroom floors. It is water-resistant, durable, available in many styles, and can mimic the look of wood or stone. We recommend a slight texture or matte finish for slip resistance in wet areas.
