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.
Caldwell 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- ✓Homeowners with outdated bathrooms built in the 1980s or 1990s that need a full refresh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 Caldwell:
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.
Caldwell has a mix of historic downtown homes, mid-century construction, and newer subdivision development. Older homes often need comprehensive updates while newer homes benefit from finish upgrades.
Pre-1960 (Downtown)
Older bungalows and farmhouse-style homes with vintage character but aging systems. Plumbing, electrical, and insulation often need updating alongside cosmetic work.
1970s–1990s
Ranch homes and early subdivision construction with standard finishes reaching end of life.
2000s–present (South Caldwell)
Newer builder-grade homes with modern systems but standard finishes that homeowners upgrade over time.
Common issues in Caldwell homes
- •Aging plumbing and electrical in pre-1970 homes
- •Small kitchens with inadequate storage and counter space
- •Outdated bathrooms with original fixtures
- •Poor insulation in older construction
- •Builder-grade finishes wearing out in 2000s homes
Material selection affects the look, durability, and cost of your bathroom remodel. Here are the most popular options we install in Caldwell:
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:
1
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.
2
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.
3
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.
4
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.
5
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.
6
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.
7
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 Caldwell:
| 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. |
Typical range: $12,000 – $55,000+
Most projects: $22,000–$35,000
The final cost of your bathroom remodel in Caldwell 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.
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.

- ●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

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.
Do you provide a warranty on bathroom remodels?
Yes. We provide a workmanship warranty covering installation quality and craftsmanship. Manufacturer warranties on fixtures, tile, and materials are separate and vary by product. We provide documentation for all warranty coverage at project completion.
