Los Angeles permit notes · Bathroom Remodel

What we resolve before drawings begin.

  • 01

    Waterproofing as an assembly

    We install full Schluter or equivalent waterproofing assemblies — not just a liner under tile. This is the difference between a 15-year bathroom and a 5-year leak.

  • 02

    LADBS permits when fixtures move

    Relocating a toilet, shower, or vanity drain pulls LADBS plumbing permits. We pull them so resale and insurance are clean.

  • 03

    Older LA framing

    Pre-1960 LA homes often have undersized joists or rotted subfloor below tile. We expose and address this before new substrate goes down.

Bathroom intel · plumbing brands & waterproofing · Los Angeles spec

A bathroom remodel succeeds or fails at two specs: the shower waterproofing system and the brand of mixing valve in the wall. Everything else is finishes.

The manufacturers we actually specify.

  • Schluter Systems

    premium

    Iserlohn, Germany

    KERDI waterproofing membrane · the gold standard

    Sheet-applied bonded waterproofing > liquid-applied for any shower we install. KERDI-LINE drains let you do single-pitch curbless wet rooms.

  • Wedi / Hydro Ban

    premium

    Germany · USA (Laticrete)

    Foam-board waterproof shower substrate · alternative to Schluter

    Wedi board is structurally waterproof — no membrane needed. Faster on commercial-grade tile installs.

  • Kohler

    workhorse

    Kohler, WI · founded 1873

    Toilets, tubs, vanities, faucets · the American default

    Wide dealer network in LA = parts available for 25-year-old fixtures. Class Five flush is still industry standard.

  • Toto

    premium

    Kitakyushu, Japan

    Toilets (Drake, Aquia, Neorest) + Washlet bidet seats

    Tornado-flush + CeFiONtect glaze means actually cleaner bowls. Washlet S550e is the single most-requested upgrade on master baths under $25k.

    1-yr full / 5-yr limited

  • Grohe / Hansgrohe

    premium

    Germany

    Thermostatic shower valves + faucets

    SilkMove cartridge (Grohe) and Hansgrohe AXOR Citterio are the only valve systems we'll spec behind tile we never want to open again.

  • Delta / Brizo

    workhorse

    Indianapolis, IN

    MultiChoice rough-in valves + DIAMOND seal tech

    MultiChoice rough lets you change trim style 10 years later without opening the wall — meaningful in flip and rental work.

  • Moen

    value

    North Olmsted, OH

    Reliable mid-market faucets with lifetime drip-free warranty

    Best value-tier pick when budget is tight; Posi-Temp valve is bulletproof.

  • Duravit

    premium

    Hornberg, Germany

    European sinks, toilets, wall-hung tanks (DuraSystem)

    Wall-hung toilets save 9–12 inches of floor depth — the only way to fit a real toilet in a 36-inch powder room.

  • Geberit

    premium

    Switzerland

    In-wall flush systems for wall-hung toilets

    Geberit Sigma in-wall carrier is the global standard — 25-year flush mechanism warranty.

Specification gotchas we resolve before contract.

  1. 01

    Pre-slope under the pan.

    Even bonded-membrane systems still need a 1/4" per foot slope under the membrane. We pour mud-bed every time — never a flat pan.

  2. 02

    Curbless threshold structural drop.

    A flush wet-room entry requires lowering the floor framing 1–1.5 inches inside the bathroom. We frame this in or recommend a low-profile linear drain when the joists won't take it.

  3. 03

    Exhaust fan CFM ↔ door undercut.

    CA code requires 50 CFM minimum continuous or 100 CFM on demand, and a 3/4-inch door undercut to provide make-up air. Skip the undercut and the fan starves.

Los Angeles · Bathroom Remodel FAQ

Questions Los Angeles homeowners ask first.

Start an LA bathroom remodel brief. We'll review scope, waterproofing assembly, permit path, and a fixed-scope contract.

  1. What does a Los Angeles bathroom remodel cost?
    Most LA bath remodels land $35K–$90K all-in. Primary suite gut renovations with structural moves can reach $120K+.
  2. How long does an LA bath remodel take?
    4–8 weeks of active construction. Design and material lead times add 4–8 weeks before demo starts.
  3. Can you do multiple baths in one project?
    Yes — we frequently do two or three baths in one phase, which lowers per-bath cost vs. doing them separately.
  4. Do I need a LADBS permit to remodel an LA bathroom?
    Relocating a toilet, shower drain, or vanity triggers a LADBS plumbing permit. Like-for-like fixture swaps usually don't. We pull what's required so resale and insurance stay clean.
  5. Can you waterproof a curbless or zero-threshold shower?
    Yes — we build full Schluter-Kerdi or equivalent bonded waterproofing assemblies with a recessed pan and properly sloped substrate. This is how a curbless shower stays leak-free for 15+ years.
