Shower Contractor in Nampa, Idaho
Licensed shower remodel contractor for Nampa homeowners — tub-to-shower conversions, custom tile walk-in showers, Schluter waterproofing, and frameless glass built right
Nampa is Canyon County's largest city and one of the most actively growing communities in the Treasure Valley. The city has a wide range of housing — from established older neighborhoods with homes dating to the 1940s and 1950s, to newer subdivisions built in the past decade. That range creates an equally wide range of shower remodel projects — from complete rebuilds of deteriorated original showers in older homes, to cosmetic upgrades of builder-grade tile in newer construction.
What every Nampa shower remodel has in common is this: the most important decision is not the tile you choose. It is whether the waterproofing beneath that tile is done correctly. Iron Crest Remodel installs Schluter KERDI waterproofing on every tile shower we build — not as an upgrade, but as the foundation of any shower that performs for decades rather than failing within five years. We see the result of shortcuts in shower waterproofing every time we demolish an existing shower that needs to be replaced.
Tub-to-Shower Conversion
Remove the existing tub and convert the alcove to a walk-in or step-in tile shower with Schluter KERDI waterproofing, your choice of porcelain tile, and a frameless glass panel or door. The most requested project for Nampa primary bathrooms where the tub is never used. Typical cost $5,000–$13,000.
Builder Shower Surround Replacement
Remove fiberglass or basic ceramic builder shower and replace with custom tile, Schluter waterproofing, and frameless glass. Transforms the daily use of the primary bathroom and significantly improves resale value. Most common shower upgrade in Nampa's 2000s and 2010s new construction.
Walk-In Shower with Heated Floor
Custom walk-in shower with electric heated floor mat, large-format porcelain tile, frameless glass enclosure, built-in niche, and quality fixtures. A complete primary bathroom shower upgrade for Nampa homeowners investing in their home's primary bathroom experience.
Curbless Accessible Shower
Zero-threshold shower with linear drain, grab bar blocking, optional fold-down bench and handheld showerhead. ADA-compatible design for aging-in-place planning or accommodating family members with mobility needs in Nampa homes.
Every shower demolition tells a story about how the previous shower was built. In Nampa's older homes, we commonly find original mortar-bed showers that have failed at the pan liner; water-damaged green board that was used instead of proper cement board or waterproofing membrane; and crumbling substrate from years of slow moisture infiltration that the homeowner was not aware of until the floor began to feel soft.
In newer Nampa homes, we find fiberglass surrounds with caulk failures at the tub lip, and basic ceramic tile showers where the grout has darkened and the caulk at the base is black with mold — symptoms of a shower that was not built with a proper waterproofing system from the start.
Iron Crest eliminates these failure modes with Schluter KERDI membrane on every shower we build. KERDI is installed before any tile is set, covers every surface inside the shower enclosure, and is reinforced with KERDI-Band at all seams and transitions. The result is a shower that cannot fail from moisture infiltration behind the tile — because the waterproofing does not depend on grout staying intact.

Every Iron Crest shower project in Nampa follows a structured process that ensures quality outcomes and keeps homeowners informed at every stage. Here is what to expect from start to finish:
Free In-Home Estimate and Scope Review
We visit your Nampa home at no charge, assess the existing shower or tub, discuss your design goals and budget, and develop a clear scope of work with itemized pricing. We bring tile samples so you can evaluate options in your bathroom's actual lighting. Estimates are provided in writing with no commitment required.
Permitting with City of Nampa
We submit all required permit applications to the City of Nampa Building Department — plumbing permits for any drain or supply work, electrical permits for heated floors or lighting, and structural permits where applicable. We track approval and respond to any plan review comments.
Demolition and Inspection
Existing shower or tub is fully demolished to the studs and subfloor. We inspect the framing, subfloor, and existing plumbing for any damage or conditions that need to be addressed before installation begins. Any findings are documented and priced before proceeding — no mid-project surprises.
Waterproofing and Rough-In
New cement board or Schluter Kerdi-Board is installed on walls and subfloor. Schluter KERDI membrane is bonded across all surfaces. KERDI-Band is applied at all seams, corners, and penetrations. The Schluter drain is installed with KERDI-Seal waterproof connection. Plumbing and electrical rough-in is completed and inspected.
Tile, Glass, and Fixtures
Tile is set on walls and floor with proper mortar, grout, and cure sequences. Heated floor mat is installed before tile if specified. Glass enclosure is measured and fabricated after tile cures, then installed. Fixtures, showerhead, and controls are installed and tested. Final inspection with the City of Nampa is scheduled and passed.
The following government agencies, industry organizations, and official resources provide additional information relevant to your remodeling project.
How much does a tub-to-shower conversion cost in Nampa, Idaho?
A tub-to-shower conversion in a Nampa home typically costs $5,000–$13,000 for a standard 5-foot alcove conversion with tile, Schluter KERDI waterproofing, and a frameless glass panel or door. The cost varies primarily with tile selection — entry-level porcelain runs $7–$10 per square foot installed; designer large-format tile can run $12–$20+ per square foot. Additional costs arise if Nampa's older housing stock reveals plumbing or structural surprises during demolition. Many Nampa homes have cast-iron or galvanized plumbing that may need addressing during a shower remodel. Iron Crest provides a fully itemized estimate before any work begins, and clearly communicates any change orders if unexpected conditions are found during demolition.
What should I know about shower remodels in older Nampa homes?
Nampa has a significant inventory of older homes — pre-1970 and even pre-1950 properties in established neighborhoods. These homes present specific shower remodel challenges: original galvanized or cast-iron drain plumbing that may need replacement; subfloors with limited structural depth that make curbless drain configurations more complex; older framing that may require reinforcement to support the weight of a full tile shower; and original cast-iron tubs that weigh 300–400 pounds and require careful removal. Iron Crest has extensive experience in Nampa's older housing stock. We perform a thorough pre-construction assessment and clearly communicate any scope items we discover before proceeding — you are never surprised by an unexpected cost after work begins.
What is Schluter KERDI waterproofing and do I need it for my Nampa shower?
Schluter KERDI is the industry-standard tile shower waterproofing membrane that bonds directly to the substrate before tile is set. It creates a continuous waterproof barrier that eliminates the moisture cavity behind tile where water migrates and causes mold growth, structural damage, and eventual shower failure. In Nampa's older homes, we frequently encounter failed waterproofing from previous shower builds — soft subfloors, mold in wall cavities, and crumbling substrates — when we open walls during demolition. For every Nampa shower Iron Crest builds, Schluter KERDI is the standard — it protects your investment and eliminates the failure mode that causes costly rebuilds.
Can I add a walk-in shower to my Nampa home's primary bathroom without major renovation?
In most Nampa primary bathrooms, a walk-in shower can be added through a tub-to-shower conversion without reconfiguring the entire bathroom. The existing tub alcove — typically 5 feet long — becomes a step-in or walk-in shower with proper waterproofing, tile, and a frameless glass panel or door. For a larger walk-in footprint, some Nampa homeowners expand into the adjacent closet or shift the vanity position — these options require plumbing relocation and structural assessment but dramatically improve the shower experience. Iron Crest evaluates your specific Nampa bathroom layout and provides options at multiple price points during the free estimate.
Does my Nampa shower remodel require permits?
Yes. Shower remodels in Nampa that involve plumbing modifications require a plumbing permit from the City of Nampa Building Department. Projects with electrical work — heated floors, exhaust fan upgrades, or lighting changes — require an electrical permit. Structural work requires a building permit. Permits are not optional and are not just bureaucratic requirements — they ensure your shower is inspected by a licensed inspector and meets Idaho Building Code, which matters for insurance coverage and for disclosure when you sell. Iron Crest handles every permit application for your Nampa shower project and coordinates all required inspections.
What tile options are available for a Nampa shower remodel on a budget?
Nampa homeowners working within a budget have good options for creating a significantly improved shower without premium material costs. For shower walls, standard 12x24 porcelain tile in a light neutral tone reads as contemporary and clean at $3–$6 per square foot material cost. Subway tile (3x6 porcelain) remains a classic, budget-friendly option that is never out of style. For shower floors, 2x2 or 3x3 mosaic tile is economical and handles the drain slope well. The budget decision that matters most is not tile — it is waterproofing. Cutting costs on the Schluter KERDI system to save $300–$500 on a $9,000 shower remodel is the choice that leads to a $12,000 rebuild in seven years. Iron Crest installs proper waterproofing on every project regardless of the overall project budget.
Can I include a heated shower floor in a Nampa shower remodel?
Yes — electric in-shower heated floors are available on any Nampa shower remodel where the electrical panel has capacity for an additional circuit. We install Nuheat or Schluter DITRA-HEAT electric mat systems under the shower floor tile, connected to a programmable thermostat. The installation requires an electrical permit from the City of Nampa and inspection by the city electrical inspector. The cost addition is typically $800–$1,800 for the shower floor area, which is a modest addition to a $7,000–$15,000 shower remodel. Heated shower floors are one of the most consistently appreciated daily-use upgrades in any bathroom remodel — the satisfaction is immediate every cold Nampa winter morning.
How long does a shower remodel take in a Nampa home?
A standard shower remodel in a Nampa home — tub removal or existing shower demolition, waterproofing, tile, grouting, and glass — takes approximately 7–12 business days from permit issuance to completion. Permit processing with the City of Nampa Building Department typically adds 1–2 weeks before construction can start. Older Nampa homes with plumbing or structural issues discovered during demolition may add 1–3 additional days for remediation. Heated floor installations do not significantly extend the timeline since the mat is installed during the tile phase. Iron Crest provides a realistic schedule at estimate time so you can plan for the bathroom to be out of service during construction.
