Bathroom Remodeling in South Boise / Vista
Walk-in shower conversions, footprint expansions, primary suite additions for 1945-1970 South Boise post-war homes — EPA RRP, value-tier premium finish.
Bathroom remodeling in South Boise / Vista addresses 1945-1970 post-war GI-tract construction with original 5'×7' to 5'×8' bathrooms — typically only one full bathroom in the original home plus sometimes a small powder room. Modern primary suites are rare in original South Boise construction, so primary suite additions and footprint expansions are the dominant project pattern. Iron Crest's South Boise bathroom work emphasizes Schluter Kerdi waterproofing on every shower, walk-in shower conversions from original built-in cast iron tubs, footprint expansion into adjacent closets or hallways, primary suite additions on the rear of original homes, EPA RRP universal for pre-1978 work, knob-and-tube electrical replacement, cast iron drain replacement, and value-tier premium finish appropriate to typical $385K-$725K South Boise property values.
Bathroom strategy in South Boise depends on era and primary vs. secondary status.
1945-1955 immediate post-war
Original 5'×7' bathrooms with built-in cast iron tub-shower combo, single sink, sometimes high-tank toilet (long since replaced). Cast iron drains universal. Modern scope: walk-in shower conversion or primary suite addition.
1955-1965 expanded post-war
Slightly larger 5'×8' bathrooms with built-in tub-shower combos. Sometimes pastel tile palettes (pink, mint, blue). Modern scope: full renovation, walk-in shower conversion.
1965-1975 ranch construction
Larger 6'×9' to 7'×11' bathrooms, sometimes separate tub and shower. Modern scope: finish modernization, walk-in shower upgrade.
1920s-40s pre-war (Boise State / University area)
Earlier construction with smaller 5'×7' bathrooms, sometimes plaster-and-lath walls. Pedestal sinks original. Modern scope: comprehensive renovation with plaster coordination.
South Boise bathroom renovations cluster into recognizable shapes by era and ambition.
1. The Primary Suite Addition
Rear addition (typically 280-450 sq ft) providing primary bedroom, walk-in closet, and primary bath with walk-in shower, double vanity. Resolves South Boise's universal lack of adequate primary suite in original construction.
Target homes: 1945-1970 South Boise homes lacking primary suite. Permit: full plan review with structural drawings.
2. The Footprint Expansion
Existing original bathroom too small; expansion into adjacent closet, hallway, or bedroom. Walk-in shower conversion. Sometimes double vanity if space allows. Premium fixtures.
Target homes: 1945-1970 South Boise homes with undersized original bathrooms. Permit: full plan review with structural drawings if walls move.
3. The Walk-In Shower Conversion
Conversion of original built-in cast iron tub-shower combo to walk-in shower without major footprint change. Schluter Kerdi waterproofing. Premium tile. Frameless glass enclosure. Most cost-effective South Boise bathroom upgrade.
Target homes: South Boise homes wanting modern walk-in shower in existing bath footprint. Permit: standard plumbing/electrical permits.
4. The Comprehensive Refresh
Existing bathroom layout works but finishes need updating. Walk-in shower conversion, vanity replacement, tile and fixture refresh.
Target homes: South Boise bathrooms with sound layout but dated finishes.
5. The Boise State Investor Renovation
Boise State University area home bathroom optimized for owner-occupant + rental viability. Durable finishes (porcelain tile, quartz, semi-custom vanity), walk-in shower with frameless glass, code-compliant electrical.
Target homes: Boise State / University area homes with mixed considerations.
The South Boise / Vista spans roughly two square miles with distinct sub-neighborhoods, each with its own remodeling personality.
Vista Avenue corridor
The principal commercial-residential corridor along Vista Avenue running south from Boise Bench toward Boise State University. Mix of 1945-1965 post-war single-family homes (1,100-1,800 sq ft) and small commercial buildings. Sometimes called "Old Vista" by long-time residents. Lots typically 50' × 110' to 60' × 130'. Strong walkability to Vista Avenue restaurants and small businesses. Home values $385K-$625K.
Depot Bench flats
The lower-elevation neighborhood between the Boise Bench bluff and the Boise River, south of downtown. Distinct from the bench-top neighborhoods (which are higher elevation). 1940s-60s post-war housing on slightly larger lots (60' × 120' typical). Mature tree canopy along streets. Quieter than Vista corridor. Home values $425K-$685K.
Boise State / University area
The neighborhoods immediately surrounding Boise State University, including Lusk Street, University Drive, and adjacent residential streets. Mix of 1920s-50s single-family homes (some now student rentals) and newer infill construction. Walking distance to campus, downtown bridges, and Greenbelt. Demographic mix includes faculty, professionals, and families plus some student rental conversions. Home values $385K-$625K (single-family) with active investor activity.
Borah Park / Manitou Park
The neighborhood centered on Borah Park and Manitou Park along Manitou Street and surrounding residential streets. 1945-1965 post-war housing wave. Strong family-focused community character. Slightly larger lots (0.18-0.28 acre). Home values $425K-$675K.
Mayfair Drive area
The Mayfair Drive corridor and surrounding residential streets in the southern reach of South Boise. 1955-1975 ranch and split-level construction (slightly later than Vista). Larger homes (1,600-2,400 sq ft). Quiet residential character with mature landscaping. Home values $475K-$725K.
Vista North / River Road area
The northern transitional zone between South Boise and downtown along River Road and the Boise River corridor. Mix of 1920s-40s pre-war and 1950s-60s post-war housing. Some homes have river or Greenbelt frontage. Closer to downtown employment than other South Boise sub-areas. Home values $475K-$785K.
South Boise bathroom pricing reflects value-tier finish, EPA RRP for pre-1978 homes, and Schluter waterproofing.

South Boise / Vista is not within any City of Boise Historic District. There is no Historic Preservation Commission review for these neighborhoods. No HOAs for most South Boise streets — historically working-class to middle-class neighborhoods without modern HOA structure.
City of Boise standard permits apply for electrical, plumbing, structural, and mechanical work. Permit timelines are typically 2-4 weeks for over-the-counter scopes and 3-5 weeks for full plan review with structural drawings.
EPA Lead Renovation, Repair and Painting (RRP) Program applies to virtually every South Boise project given the universal pre-1978 construction. Iron Crest carries RRP certification and follows lead-safe work practices including HEPA containment, wet-paste paint scraping, lead-safe disposal.
Asbestos testing required for pre-1980 demolition work. Common in popcorn ceilings, vinyl asbestos floor tile, sheet flooring mastic, pipe insulation, and sometimes original siding products on pre-1980 South Boise homes.
South Boise lots are typically smaller than West Boise or Northwest Boise (50'-60' frontage with 110'-130' depth, often 0.13-0.20 acre) but generally accommodate additions and deck work. Setback compliance occasionally constrains larger additions or detached ADUs on the smaller Vista corridor lots.
Some South Boise streets are within the Boise State University planning district overlay, which may affect specific permit requirements for student-rental conversions or multi-family work. Iron Crest verifies overlay zoning at consultation for projects in the immediate university area.
Boise State University area homes sometimes have rental-conversion permit history that affects insurance, code compliance, and resale documentation. Iron Crest reviews permit history during pre-construction for university-area homes.

Required universally in South Boise. Iron Crest is RRP-certified.
Will Schluter Kerdi waterproofing be used?
Yes, on every shower without exception.

What if hidden mold is discovered?
Common in pre-1990 showers. Iron Crest assesses and remediates: $1,500-$8,500.
Should I do walk-in shower or keep the tub?
Primary baths typically benefit from walk-in conversion. Secondary baths used by kids may benefit from tub retention. South Boise families with kids often retain at least one tub in the home.
