Shower Contractor in Caldwell, Idaho
Licensed shower contractor for Caldwell homeowners — tub-to-shower conversions, older bathroom updates, Schluter waterproofing, and custom tile built right the first time
Caldwell is Canyon County's county seat and one of the Treasure Valley's most established communities. The city's housing stock spans a wide range — from early 20th-century homes in historic downtown neighborhoods, to mid-century construction in established residential areas, to newer subdivisions on Caldwell's growing outskirts. That range translates directly to diverse shower remodel scopes.
Older Caldwell homes — particularly those built before 1980 — often have shower situations that require full demolition and rebuild rather than cosmetic updates. Original mortar-bed showers with failed pan liners, tile installed over green board that is saturated with moisture, and plumbing that predates modern materials are common findings when we open shower walls in Caldwell's established neighborhoods. These are not problems that can be patched — they require starting over correctly.
Iron Crest Remodel approaches every Caldwell shower project with an honest assessment of existing conditions and a commitment to building the replacement correctly. Schluter KERDI waterproofing on every shower, permits through the City of Caldwell, and a 5-year workmanship warranty backing every project. Idaho RCE License #6681702.
Older Shower Tear-Out and Rebuild
For Caldwell homes with failing original showers — soft floors, moldy grout, tile separating from walls — a complete tear-out back to the studs and subfloor is the correct approach. We assess and repair any moisture damage, then rebuild with Schluter KERDI waterproofing, new cement board substrate, current-standard tile, and proper fixtures. The only approach that results in a durable finish.
Tub-to-Shower Conversion
Remove the existing tub and convert the alcove to a walk-in tile shower. Most common project in Caldwell primary bathrooms. Works within the existing footprint without structural changes in most cases. Schluter waterproofing, porcelain tile, and a frameless glass panel. Cost $4,800–$13,000.
Builder Surround Replacement
For Caldwell homes with newer fiberglass or basic ceramic builder surrounds, we remove and replace with custom tile on Schluter KERDI. Transforms the visual quality of the primary bathroom and eliminates the maintenance issues of yellowing fiberglass and staining grout.
Accessible Shower Design
Curbless zero-threshold entry, grab bar blocking, fold-down bench, and handheld showerhead for aging-in-place or mobility accommodation. Available on any Caldwell shower build at modest incremental cost when planned from the start of construction.
Shower demolition in Caldwell reveals the history of how bathrooms were built over the past seven decades. In Caldwell's pre-1970 homes, we commonly find original mortar-bed showers with lead or rubber pan liners that have cracked or separated at drain connections — leaking slowly into the subfloor for years before symptoms appear. In homes from the 1970s and 1980s, green board (moisture-resistant drywall) was the standard substrate — it resists bulk water but is not waterproof and absorbs moisture vapor through grout lines over time.
In more recent Caldwell construction, fiberglass surrounds and basic tile installations were built without bonded waterproofing membranes — a cost-saving shortcut during tract construction that leads to grout failure and caulk decay within 5–10 years.
KERDI Membrane — Iron Crest Standard
Every Caldwell shower Iron Crest builds receives the full Schluter KERDI membrane installation. KERDI bonds to the substrate and creates a continuous waterproof surface under every square inch of tile. No cavities, no membrane gaps, no reliance on grout staying intact indefinitely.
Moisture Damage Assessment and Repair
Before any waterproofing goes down, we inspect every framing member and section of subfloor exposed during demolition. Any moisture-damaged wood is replaced before the new installation begins. We document conditions photographically and discuss findings with you before proceeding.
KERDI-Band at All Transitions
Wall-to-floor corners, inside corners, pipe penetrations, and drain connections all receive KERDI-Band reinforcement before field membrane installation. These transitions are where non-Schluter systems fail first. Iron Crest treats every transition as a critical waterproofing point.
Many Caldwell homeowners are long-term residents planning for decades of continued use of their home. Iron Crest builds aging-in-place features into Caldwell shower remodels that add value now and protect long-term livability:

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 Caldwell, Idaho?
A tub-to-shower conversion in a standard Caldwell home alcove typically runs $4,800–$12,000, making it one of the more affordable major bathroom improvements available. The primary cost drivers are tile selection and whether a frameless glass door or panel is included. Entry-level porcelain tile with a Schluter KERDI waterproofing system and a simple frameless panel can come in under $7,000 in a straightforward Caldwell alcove. Design-forward large-format porcelain with a hinged frameless door and a built-in niche runs $9,000–$13,000. Caldwell's older housing stock occasionally produces plumbing or structural discoveries during demolition that affect cost — Iron Crest documents any unexpected conditions and discusses options before proceeding.
What shower challenges do Caldwell's older homes present?
Caldwell has a significant inventory of older homes — many built in the 1950s, 1960s, and 1970s — with original or early-replacement plumbing, subfloors, and bathroom configurations. Specific shower remodel challenges in Caldwell's older housing include: original cast-iron drain plumbing that may need sections replaced during rough-in modification; galvanized supply lines that should be replaced during a shower remodel if not already updated; subfloor joists that may not be sized to support the weight of a full mortar-bed tile shower without reinforcement; and narrow alcove dimensions in homes with compact original bathrooms. Iron Crest has worked extensively in Caldwell's established neighborhoods and performs a thorough site assessment before finalizing any estimate. We never discover a problem after work starts without communicating it to you first.
Is Schluter waterproofing necessary for an older Caldwell home shower?
Yes — and it is especially important in older Caldwell homes. The original shower waterproofing systems in pre-1980 homes were typically either a lead or PVC pan liner beneath a mortar bed, or in later decades, green board (paper-faced moisture-resistant drywall) that is not actually waterproof behind tile. Both systems fail over time. When we demolish old showers in Caldwell, we regularly find: deteriorated pan liners that have been leaking slowly for years, green board completely saturated and beginning to crumble, and subfloor rot that has spread beyond the shower pan area. Schluter KERDI eliminates the failure mode entirely by bonding a continuous waterproof membrane to the substrate before tile is ever set. It costs a fraction of the repair bills caused by failed waterproofing.
What are budget-friendly tile options for a Caldwell shower remodel?
Caldwell homeowners looking for value in a shower remodel have several tile options that deliver a significantly improved look without premium material costs. Standard 12x24 porcelain in a neutral tone — light gray, warm white, or cream — is available at $2.50–$5 per square foot material cost and reads as contemporary and clean in any bathroom. Subway tile (3x6 porcelain) is a timeless option that is budget-friendly and always looks intentional. For shower floors, 2x2 porcelain mosaic tile handles the drain slope effectively and is available at modest cost. The most important budget decision is not tile selection — it is ensuring proper Schluter waterproofing is not cut to reduce the bid. Iron Crest includes KERDI on every project regardless of the overall budget.
Do I need a permit for a shower remodel in Caldwell?
Yes. Shower remodels in Caldwell that modify or relocate plumbing require a plumbing permit from the City of Caldwell Building Department. Electrical work for heated floors or circuit additions requires an electrical permit. Structural modifications require a building permit. Permits are not optional — they protect your homeowner's insurance coverage, ensure proper inspection, and prevent disclosure issues at resale. In Caldwell's older homes, permits also catch any code-compliance issues that need to be addressed during the remodel. Iron Crest handles all Caldwell permit applications and inspections on your behalf.
How do I update an outdated 1960s or 1970s bathroom shower in Caldwell?
Updating a 1960s or 1970s bathroom shower in Caldwell typically involves a full demolition back to the studs — which is the correct approach rather than tiling over existing tile. Original 4x4 ceramic tile from this era was installed over green board or mortar beds that may have decades of moisture infiltration behind them. Tiling over existing tile does not address the waterproofing failure and adds weight to a substrate that may already be compromised. Iron Crest removes everything to the framing, inspects and repairs any structural or moisture damage, installs Schluter KERDI waterproofing, and builds a current-standard tile shower that looks and performs completely differently from the original. For Caldwell's older bathrooms, this is the only approach that results in a durable finished product.
Can I add a heated shower floor to my Caldwell bathroom remodel?
Yes — electric heated shower floors are available for any Caldwell shower remodel where the electrical panel has capacity. We install Nuheat or Schluter DITRA-HEAT systems beneath the shower floor tile, connected to a programmable thermostat outside the shower. The installation requires an electrical permit from the City of Caldwell and a dedicated circuit. In Caldwell's older homes, we assess the existing electrical panel capacity before recommending a heated floor addition — some older panels require an upgrade to accommodate additional circuits. When the panel supports it, a heated shower floor adds $800–$1,800 to the shower scope and is consistently one of the most appreciated features in any bathroom remodel.
What ADA or accessibility features are available for Caldwell shower remodels?
Caldwell has a significant population of long-term homeowners who are planning for aging-in-place or accommodating family members with mobility needs. Accessible shower features Iron Crest installs in Caldwell include: curbless (zero-threshold) shower entry with a linear drain for step-free access; grab bar blocking installed in all shower walls during construction so grab bars can be added at any time without opening tile; a fold-down teak or stainless bench; a handheld showerhead on an adjustable slide bar; and non-slip matte floor tile. These features can be incorporated into any Caldwell shower at modest incremental cost during the construction phase — the blocking alone adds almost nothing to the project cost and eliminates the need to open walls later.
