LA Bathroom Remodel Cost 2025: Title 24 Lighting, Slab Plumbing, Hillside Homes

Why LA bathroom pricing differs from other cities around the country

LA homes span slab‑on‑grade, crawlspaces, and steep hillside foundations. Slabs increase plumbing costs. Crawlspaces improve access. Hillside houses add drainage and vent complexity due to slope and airflow patterns. Many Westside neighborhoods also require wildfire‑resistant product choices.

Slab versus crawlspace plumbing
