Shower Remodel Checklist for Boise Homeowners
A comprehensive, step-by-step planning guide to help you navigate every stage of your shower remodel — from budgeting and design decisions to waterproofing verification, Boise permit requirements, and post-installation care.
A successful shower remodel starts long before tile is ordered or a contractor is hired. The pre-planning phase is where you define the scope, set realistic financial expectations, and develop a clear vision for the finished space. Rushing through this phase is the most common cause of mid-project change orders and budget overruns in Boise bathroom projects.
Assess Your Current Shower
Document every issue with your current shower — cracked grout, mildew stains, leaking valve, poor water pressure, inadequate drainage, outdated fixtures, or a tub you never use
Check for water damage behind the shower walls by inspecting adjacent rooms for soft drywall, peeling paint, or musty odors that indicate moisture intrusion behind the tile
Measure the existing shower footprint including ceiling height, door swing clearance, and distance to the vanity and toilet — these dimensions drive your design options
Determine whether you want a like-for-like replacement within the existing footprint or a layout change that expands or reconfigures the shower space
Identify accessibility needs — grab bars, bench seating, curbless entry, handheld showerhead, and non-slip flooring are increasingly popular in Boise homes for aging-in-place planning
Set Your Budget
Shower remodel costs in the Boise area vary significantly based on scope. Understanding the ranges helps you set realistic expectations and avoid sticker shock during the design phase.
| Scope | Cost Range | What's Included |
|---|---|---|
| Basic Refresh | $5K–$8K | New tile, standard fixtures, curtain or basic glass door, minimal plumbing changes |
| Mid-Range Remodel | $10K–$18K | Large-format tile, frameless glass, rain showerhead, niche, linear drain, new valve |
| Premium Custom | $18K–$25K+ | Natural stone, body sprays, bench seat, LED lighting, curbless entry, steam option |
Always include a 10–15% contingency reserve. Older Boise homes — especially those built before 1985 — frequently reveal hidden water damage, galvanized plumbing, or inadequate subfloor structure behind shower walls once demolition begins.
Gather Inspiration
Save photos of shower designs you like — pay attention to tile patterns, fixture finishes, glass enclosure styles, and niche placement. Pinterest and Houzz are excellent starting points
Visit Boise-area tile showrooms (Floor & Decor, International Floor Covering, The Tile Shop) to see materials in person. Photos rarely capture true color and texture accurately
Consider your home style — Craftsman details for North End homes, clean contemporary lines for new construction in Meridian, rustic-modern for Eagle and Star properties
Every design decision you finalize before construction begins eliminates a potential delay or change order during the build. Lock these selections in during the planning phase and confirm material availability before scheduling your demolition date.
Shower Type & Configuration
Walk-in shower, tub-to-shower conversion, alcove replacement, curbless zero-entry, or corner neo-angle. Each type has different structural, waterproofing, and drainage requirements. Curbless showers require a pre-sloped mortar bed or a factory-sloped foam pan and careful floor transition planning.
Tile Selection
Porcelain tile is the most popular choice in Boise shower remodels for its durability and moisture resistance. Large-format tiles (12x24 or larger) reduce grout lines and simplify cleaning. Natural stone requires sealing. Mosaic tile on shower floors provides superior slip resistance. See our shower tile patterns guide for Boise-specific recommendations.
Fixtures & Valve System
Choose between a single-function showerhead, a rain-and-handheld combo, or a multi-outlet system with body sprays. Thermostatic mixing valves maintain consistent water temperature and are strongly recommended for households with children or seniors. Brushed nickel and matte black are the two most requested fixture finishes in Boise.
Glass Enclosure
Frameless glass panels (3/8-inch or 1/2-inch tempered) provide a clean, open look and are the premium standard in Boise shower remodels. Semi-frameless and framed enclosures cost less but collect more water deposits along the metal channels. Bypass sliding doors work well for alcove showers with limited swing clearance.
Drainage System
Standard center drains work for most showers. Linear (trench) drains along one wall allow for a single-slope floor pitch, simplify large-format tile installation, and provide a modern aesthetic. Linear drains are essential for curbless shower designs to prevent water from escaping the wet area.
Niches, Benches & Accessories
Recessed niches for shampoo storage should be positioned between 48 and 60 inches from the floor. Built-in bench seats require structural blocking and proper waterproofing. Corner caddies, grab bars rated for 250+ pounds, and fold-down seats are additional options that should be planned during framing, not added as afterthoughts.
Choosing the right contractor for your shower remodel is the single most consequential decision you will make. Waterproofing failures, improper tile installation, and code violations are expensive to fix after the fact and are almost always the result of hiring the wrong crew. Use this checklist to vet every candidate.
Licensing & Insurance
Verify the contractor holds a valid Idaho contractor license through the Idaho Division of Building Safety (DBS). Confirm they carry general liability insurance (minimum $500,000) and workers' compensation coverage. Ask for certificates of insurance and verify them directly with the insurance carrier. An uninsured contractor working in your home exposes you to personal liability for injuries and property damage.
References & Portfolio
Request references from at least three recent shower remodel projects in the Boise area. Ask to see completed work in person — photos can hide imperfections that are visible on a site visit. Look for consistent grout lines, properly aligned tile patterns, clean caulk joints at transitions, and well-sealed glass enclosure hardware. Read Google reviews and check the contractor's BBB rating for complaint patterns.
Boise Experience & Written Estimate
Prioritize contractors with documented experience in Boise-area homes. Homes in the North End, Boise Bench, and older Southeast Boise neighborhoods often have plumbing, framing, and subfloor conditions that require specialized knowledge. Get three written estimates with line-item detail, a clear payment schedule tied to milestones (not front-loaded), and a written timeline with start and completion dates. A reputable contractor will never demand more than 10 to 15 percent upfront as a deposit.
Boise has specific permitting requirements for shower remodels that involve plumbing, electrical, or structural changes. Skipping permits can result in fines, failed home inspections during a future sale, and voided warranties. Understanding what does and does not require a permit saves time and protects your investment.
Plumbing Permit Required: Moving the shower drain to accommodate a new layout, adding supply lines for body sprays or a handheld wand on a separate valve, converting a tub drain to a shower drain, or rerouting hot and cold supply lines to a new valve location. The City of Boise requires a licensed plumber or a contractor with a plumbing endorsement to pull the permit.
Electrical Permit Required: Installing a steam generator circuit, adding a heated floor mat with a dedicated circuit and thermostat, wiring recessed LED shower lighting on a GFCI-protected circuit, or adding an exhaust fan on a humidity-sensing switch. All electrical work in wet areas must comply with NEC Article 680 and Idaho-adopted amendments.
Building Permit Required: Structural modifications such as enlarging the shower opening by removing or relocating a wall, converting a closet into a walk-in shower, or installing a curbless shower that requires subfloor modifications to create the required slope to drain.
No Permit Needed: Cosmetic upgrades within the existing footprint — replacing tile, installing a new showerhead on the existing arm, swapping a faucet valve in the same location, replacing a glass enclosure without structural changes, or refinishing the shower pan.
Inspection Checkpoints: Rough-in inspection occurs after plumbing and electrical work is complete but before walls are closed with cement board and waterproofing. Final inspection occurs after all finish work is complete. Permit fees in the Boise area range from $100 to $400 depending on scope. Iron Crest Remodel handles all permit applications and inspection scheduling.
Once permits are approved and materials are on-site, construction begins. Each phase has specific quality checkpoints that must be verified before moving to the next step. Cutting corners during construction — especially on waterproofing and substrate preparation — leads to the most expensive failures in shower remodeling.
Step 1: Demo Day Preparation
Remove all personal items from the bathroom. Protect adjacent flooring and doorways with plastic sheeting and floor runners. Shut off the water supply to the shower at the nearest shutoff valve. Confirm a dumpster or debris removal plan is in place. Demolition of an existing shower — including tile, cement board, and the old pan or tub — typically takes 1 to 2 days. This is when hidden issues surface: water-damaged studs, mold behind the tile, galvanized plumbing, or an improperly installed original pan.
Step 2: Framing & Plumbing Rough-In
Repair or replace any water-damaged framing. Install blocking for grab bars, bench seats, glass enclosure hardware, and niche framing between studs. Rough-in new plumbing supply and drain lines per the approved design. Install the shower valve at the correct height (typically 48 inches from the finished floor for the main valve, 72 to 80 inches for a rain showerhead arm). Schedule rough-in inspection with the City of Boise before closing walls.
Step 3: Waterproofing Verification
This is the most critical quality checkpoint in any shower remodel. Cement board is installed over framing with proper fasteners and seam tape. The waterproof membrane — Schluter KERDI sheet or Laticrete HYDRO BAN liquid — is applied to all surfaces that will receive tile. Seams are overlapped by a minimum of 2 inches and sealed with KERDI-BAND or additional membrane coats. The shower pan and curb receive continuous waterproofing with no gaps or pinholes. A flood test (fill the pan with 2 inches of water for 24 hours) confirms zero leakage before a single tile is installed.
Step 4: Tile Installation & Inspection
Tile is set with the appropriate thin-set mortar for the membrane system. Layout starts from the most visible wall with full tiles at eye level and cut tiles at the bottom or in corners. Grout joints are consistent, and all inside corners and transitions receive color-matched silicone caulk instead of grout to accommodate movement. Mosaic tile on the shower floor is pitched toward the drain at a minimum slope of 1/4 inch per foot. Inspect grout lines, tile alignment, and niche edges before the crew leaves the job.
Step 5: Fixture Installation & Glass
Trim plates, showerheads, handles, and diverters are installed once tile and grout are complete. The glass enclosure is measured after tile is set to ensure a precision fit — glass fabrication typically takes 5 to 10 business days after templating. Frameless glass panels are mounted with stainless steel hardware and sealed with clear silicone at all contact points. Test every fixture for proper operation, check water temperature balance, and confirm adequate water pressure at all outlets before signing off.
Your shower remodel is not truly complete until you have protected your investment with proper sealing, coatings, documentation, and a maintenance plan. These final steps extend the life of your new shower by years and prevent the premature deterioration that plagues poorly maintained tile installations.
Grout Sealing: Apply a penetrating grout sealer to all cementitious grout joints 48 to 72 hours after grouting once the grout has fully cured. Reapply sealer every 12 months for standard grout, or use epoxy grout during installation to eliminate the need for periodic sealing entirely. Unsealed grout absorbs moisture and develops mildew within months in Boise's variable humidity.
Glass Coating: Apply a nano-coating or hydrophobic glass treatment (such as EnduroShield or Diamon-Fusion) to the interior surface of your frameless glass enclosure. This invisible coating causes water to sheet off the glass rather than forming droplets, dramatically reducing hard water spots and soap scum buildup. Reapply every 1 to 2 years depending on usage.
Warranty Documentation: Collect and organize all warranty documents: tile manufacturer warranty, fixture manufacturer warranty, glass enclosure warranty, waterproofing membrane warranty, and your contractor's labor warranty. Iron Crest Remodel provides a written workmanship warranty on all shower installations. Store digital copies in a home maintenance file for easy access during a future sale or warranty claim.
Maintenance Schedule: Establish a regular cleaning and maintenance routine: daily squeegee after use, weekly tile and glass cleaning with a pH-neutral cleaner, monthly inspection of caulk joints at glass-to-tile and tile-to-tub transitions, annual grout sealer reapplication, and a 30-day post-installation walkthrough with your contractor to address any settling, caulk shrinkage, or hardware adjustments.
How long does a shower remodel take in Boise?
A standard shower remodel in the Boise metro area typically takes 5 to 10 business days from demolition to final grout sealing, assuming a straightforward replacement within the existing footprint. A mid-range project that includes new tile, a linear drain, glass enclosure, and updated fixtures usually runs 7 to 14 days of active work. A full custom shower build involving layout changes, structural modifications, bench seats, niches, and body spray systems can take 3 to 4 weeks. These timelines assume permits are already approved and materials are on-site before demolition begins. The biggest variable in Boise is tile lead time — specialty porcelain and natural stone can take 2 to 4 weeks to arrive from distributors, so order early. Iron Crest Remodel coordinates material procurement and permit scheduling in advance to minimize downtime between phases.
Do I need a permit for a shower remodel in Boise?
It depends on the scope of work. A cosmetic refresh that replaces tile, fixtures, and glass within the existing shower footprint generally does not require a permit in Boise or Ada County. However, any project that involves plumbing relocation — moving the drain position, adding body sprays, converting a tub to a walk-in shower, or rerouting supply lines — requires a plumbing permit from the City of Boise Planning and Development Services or Ada County Development Services. Electrical work such as adding a heated floor circuit, a steam generator, or recessed shower lighting requires an electrical permit. Structural modifications like enlarging the shower opening or removing a pony wall require a building permit. Permit fees in the Boise area typically range from $100 to $400 depending on scope. Iron Crest Remodel handles all permit applications and inspection scheduling as part of our standard project management process.
How much does a shower remodel cost in Boise?
Shower remodel costs in the Boise metro area range widely based on scope and material selections. A basic refresh with new subway tile, a standard showerhead, and a curtain rod runs $5,000 to $8,000. A mid-range remodel with large-format porcelain tile, a frameless glass enclosure, rain showerhead, handheld wand, and a recessed niche typically costs $10,000 to $18,000. A premium custom shower with natural stone tile, linear drain, multiple body sprays, a built-in bench, LED accent lighting, and a floor-to-ceiling glass enclosure runs $18,000 to $25,000 or more. The general rule of thumb for bathroom projects is to invest 3 to 7 percent of your home value. For the average Boise home valued at $450,000 to $550,000, that translates to $13,500 to $38,500 for the entire bathroom, with the shower typically representing 40 to 60 percent of the total bathroom budget.
What is the best waterproofing method for a Boise shower remodel?
The two industry-leading waterproofing systems used in Boise shower remodels are Schluter KERDI membrane and Laticrete HYDRO BAN liquid-applied membrane. Schluter KERDI is a polyethylene sheet membrane that bonds directly to the cement board substrate with unmodified thin-set mortar, creating a continuous waterproof barrier behind the tile. It is fast to install and virtually eliminates moisture penetration when seams are properly overlapped and sealed with KERDI-BAND. Laticrete HYDRO BAN is a liquid-applied, load-bearing waterproof membrane that is rolled or troweled onto the substrate in two coats. It cures to form a flexible, crack-isolating barrier that is ideal for shower floors and bench seats. Both systems are approved by the Tile Council of North America and meet ANSI A118.10 waterproofing standards. Iron Crest Remodel uses Schluter KERDI as our primary system because it integrates seamlessly with the Schluter-DITRA drain and curb components for a fully bonded, leak-free shower assembly.
Should I convert my bathtub to a walk-in shower in my Boise home?
A tub-to-shower conversion is one of the most popular remodeling projects in the Boise area, particularly for master bathrooms where homeowners prefer a spacious walk-in shower over a tub they rarely use. The conversion typically involves removing the tub, rerouting the drain from a tub-style P-trap to a shower drain positioned in the floor, updating supply lines for the new valve and showerhead locations, and installing a waterproof shower pan with a curb or curbless threshold. A standard tub-to-shower conversion in Boise costs $8,000 to $15,000 depending on tile selection and fixture quality. One important consideration for resale value: real estate data for the Boise market suggests that homes with at least one bathtub sell better than homes with zero tubs. If your home has two or more bathrooms with tubs, converting one to a walk-in shower is generally a net positive for both daily use and resale. If it is your only tub, weigh the lifestyle benefit against potential buyer preferences before committing.
