San Pedro Bath Remodel 2026 | $25K-$80K, Period Homes, LADBS

A San Pedro bath sits inside a 1920s Spanish Revival, a 1910s Craftsman, or a 1950s post-war ranch in a hillside neighborhood with views toward the harbor or Point Fermin. The bath has not been touched since the 1980s, the original cast-iron tub still works but the tile around it is grouting out, the single window faces a brick chimney from the neighbor's house, and the household wants a real shower without losing the home's period character. NPLD has been designing in Los Angeles since 2016 and licensed as a CSLB general contractor since 2023, with over 200 LA builds completed including period bath restoration work. Our San Pedro baths run $25K-$80K over a 4-7 week construction window. We pull through LADBS — Express Plan Check when the project qualifies — we test for asbestos and lead paint before demo (these homes have it), and we build the modernized period baths that respect what the home originally was.

What a San Pedro Bath Remodel Costs in 2026

Three honest tiers. The entry tier, $25K-$40K, is a hallway-bath refresh: porcelain or subway tile shower, a single vanity with quartz top, refinished or replaced tub, period-appropriate fixtures (cross-handle, polished nickel or oil-rubbed bronze), a properly-vented exhaust on a humidistat, and LED lighting on a dedicated circuit. The mid tier, $40K-$60K, is a primary or larger secondary bath rebuild: curbless walk-in shower with linear drain and tile or slab walls, a dual vanity if the footprint allows, heated floors, period-appropriate trim and millwork, and original-tile preservation in the wainscot where it makes sense. The top tier, $60K-$80K, is a full primary suite rebuild: structural footprint expansion into a closet or adjacent room, freestanding tub at the window with privacy treatment, custom millwork in the period style, full-slab natural stone shower walls, and a separate water closet. LADBS permits add $1.5K-$5K.

LADBS Permits, Express Plan Check, and Old-Home Realities

San Pedro is City of LA, so LADBS handles permits. Bath remodels inside the existing footprint with no structural changes typically qualify for LADBS Express Plan Check, which processes the permit in 2-4 weeks over-the-counter. Plumbing-only or fixture-replacement work can sometimes go through a combination permit pulled by the licensed plumber. Full plan check (4-6 weeks) kicks in if the project involves moving plumbing across a wall, expanding the footprint into an adjacent room, or significant electrical upgrades. Vinegar Hill HPOZ does not affect interior bath work even on properties inside the district — exterior windows or roof changes would. Older San Pedro homes commonly have asbestos in floor tile mastic, in original sheet linoleum, and in the original plaster around the tub. Lead paint is common on original trim. We test before demo and follow EPA RRP rules for lead and Cal/OSHA rules for asbestos abatement when needed. Galvanized supply lines and cast-iron drain stacks are common in pre-1960 homes and often need to be replaced as part of the bath build.

Waterproofing, Period Fixtures, and the Detail That Matters

The single most common San Pedro bath failure we tear out is a shower from the 1980s or 1990s tiled directly over drywall without a proper waterproofing membrane. By year five or ten, the grout is failing, the substrate is rotting, and the bath is coming out. We do not build this way. Our shower assemblies use a Schluter Kerdi or equivalent waterproofing membrane over cement board, sealed corners, pressure-tested drains, and tile or slab stone set over the membrane with the proper setting bed. Period-appropriate detailing matters too: subway tile in the wainscot, hex floor tile or vintage-style penny round, polished-nickel or oil-rubbed bronze fixtures with cross-handles, a console-style sink or a furniture-style vanity rather than a modern slab-front. The original cast-iron tub gets reglazed when it is salvageable (saves $1.5K-$3K versus replacement). The exhaust fan runs on a humidistat that holds the bath at proper humidity until it dries — fixed-time fans are the reason older San Pedro baths grow black mold along the ceiling line.

• Curbless walk-in shower with linear drain and tile walls: $7K-$14K
• Schluter Kerdi waterproofing on full shower envelope: $1.5K-$3K (never skip)
• Original cast-iron tub reglazing: $400-$800 (saves replacement cost)
• Period-appropriate fixtures (cross-handle, polished nickel): $1.4K-$4K
• Galvanized-to-copper or PEX repipe for the bath wall: $1.8K-$4K
• Asbestos testing and abatement (older homes): $1.2K-$4.5K

How We Sequence the Build

San Pedro bath rebuilds run 4-7 weeks of construction once permits clear. Asbestos and lead-paint testing happens before demo (1-2 days for results). Demo strips out the existing bath including the substrate. If galvanized supply lines or cast-iron drain stacks need replacement, that happens during rough-in along with the new plumbing, electrical, and any structural framing. Schluter membrane installs and pressure-tests before any tile lay-up. Tile, slab stone, or vintage-style floor goes in next. Final fixtures, millwork, and the door swap close out the last week. The household typically keeps using a secondary bath through the build. We dust-barrier the bath at the entrance with a sealed zip wall, run a HEPA air scrubber, and isolate the HVAC return so demo dust does not migrate. The same project manager and foreman walk the project weekly with the household.
