Fast, Reliable Bathroom Remodeling Across Tarzana
A full bathroom remodel in Tarzana typically runs $9,000-$28,000, with walk-in shower installations and tub-to-shower conversions falling between $3,500 and $12,000 depending on whether your home sits on the valley floor or in the hillside zones south of Ventura Boulevard. We’re Rowan Construction Group, and our crews work Tarzana regularly - dispatch and scheduling run from our Los Angeles office, but the trucks that roll to Ventura Boulevard and Reseda Boulevard know the difference between a flat slab tract home and a hillside lot that triggers LA’s Hillside Construction Ordinance. Call (213) 221-0788 to schedule your free estimate, and we’ll put a written price in your hand before anyone picks up a tool.
Why Rowan Construction Group Sherman Oaks Is Tarzana’s Preferred Bathroom Remodeling Company
We’ve delivered bathroom remodels across Tarzana’s two distinct terrains - the 1950s-1970s slab-on-grade ranches north of Ventura, and the engineered hillside lots south of it - since 2007. That split matters. A contractor who treats every Tarzana bathroom the same will either overbid the flat-lot jobs or underbid the hillside ones and hand you a change order when the geotechnical report comes due.
Our 365-Day Done Right Promise is printed on every page of our contract, not tucked behind an asterisk. Under Clause 1 of The Haven Standard, the price is written before any work starts - always. We’ve kept projects within a few percent of the agreed number across 4,000-plus jobs because no change proceeds without a signed change order. Period.
Tarzana customers get the same documentation standard as every Rowan client: a documented photo record on every visit, background-checked uniformed technicians, and a live person answering calls 24/7. Bring a competitor’s written estimate and we’ll review it line by line at no charge - our Free Second Opinion is a standing offer.
Our Bathroom Remodeling Services in Tarzana

Full Bathroom Remodeling
A full bathroom remodel in Tarzana means different paperwork depending on your lot. On the valley floor near Tampa Avenue or Corbin Avenue, we’re typically working with 1,200-square-foot ranches where the bathroom shares a wet wall with the kitchen - standard plan check, standard permit. South of Ventura Boulevard, that same scope can trigger the Hillside Construction Ordinance, requiring slope-stability analysis and fire-resistive assembly specs under Title 24. We scope both paths before quoting, so the number you sign is the number you pay.

Walk-In Shower Installation & Frameless Glass Shower Enclosures
Walk-in shower installation in Tarzana runs $4,500-$12,000, with frameless glass enclosures priced separately based on panel count and hardware spec. In the hillside zones, we pay particular attention to drain location - relocating a drain across a slope-stability setback can force a geotechnical review even when the shower itself is modest. We map the existing rough-in against the retaining-wall load line before we write the price, not after demolition starts. Our crews have installed frameless enclosures from CWS and ECO Window Systems, sourcing glass that meets LA’s wind-load requirements for the Santa Ana corridors that rake Tarzana’s south slopes.

Tub-to-Shower Conversion
Tub-to-shower conversion in Tarzana costs $3,500-$10,000 and is one of the most common requests we see in the older ranch tracts. The 1950s-1970s tubs were often set in mortar beds on slab, and the drain configuration doesn’t always suit a modern curbless or low-threshold shower. We verify the slab condition - many Tarzana slabs carry Northridge-era patchwork - and specify the pan membrane and drain rough-in in the written quote, not as a discovery item later.

Vanities, Tile & Fixtures
Vanity installation in Tarzana runs $800-$3,000 depending on whether we’re dropping in a stock unit or reworking supply and waste lines for a floating configuration. We source Kohler and Toto fixtures through our fifty-plus brand pipeline, and we specify the tile membrane - liquid-applied or sheet - based on the bathroom’s exposure to Tarzana’s 100°F summer heat, which accelerates thermal cycling and can stress lesser assemblies.

AfterTrusted Brands We Service in Tarzana
Rowan Construction Group maintains sourcing depth across fifty-plus vetted brands, which keeps our Tarzana quotes honest rather than inflated. For bathroom remodels, we regularly specify Kohler and Toto fixtures, Cambria and Caesarstone vanity tops, and frameless glass from CWS and ECO Window Systems. We don’t markup for “premium” sourcing - the brand names in your quote are the brands we buy, and the price reflects actual vendor relationships, not aspirational retail. For Tarzana customers, this means faster lead times on replacement glass if a Santa Ana wind event damages an exterior panel during construction, and stock availability on common Kohler valve bodies that lets us finish rough-ins without waiting on backorder.
Common Bathroom Remodeling Problems We See in Tarzana Homes

- Northridge-era slab damage under original bathrooms. The 1994 earthquake stressed thousands of Tarzana’s slab-on-grade foundations, and many were patched cosmetically rather than structurally. We find cracked or settled slabs beneath original tubs and showers regularly, and we verify slab integrity before quoting pan replacement - a failed slab under a new shower is a $3,000 surprise no one wants.
- Hillside drain lines crossing slope-stability setbacks. On south-of-Ventura properties, the original 1960s-1980s plumbing often predates modern setback requirements. Relocating a shower drain without verifying the retaining-wall load path can force mid-project redesign when the deputy inspector flags the crossing. We pull the preliminary drain path before we write the scope.
- UV degradation of exterior caulking and roofing over bathroom bump-outs. Tarzana’s 100°F-plus summer days and high Santa Ana wind exposure cook exterior sealants faster than coastal climates. We specify silicone or polyurethane caulking rated for extended UV exposure on any bathroom vent, window, or bump-out penetration, and we schedule temporary roof bracing when walls are opened during wind season.
- Flat-lot permit assumptions on hillside properties. Homeowners and contractors alike pull a permit application for a “simple bathroom remodel” without checking the Hillside Construction Ordinance trigger. The plan check stalls for weeks, then demands geotechnical reports and fire-rated assemblies that add thousands. We verify the lot classification in the first site visit.

What moves the number? Hillside versus flat lot is the biggest variable in Tarzana - a south-of-Ventura bathroom with drain relocation and Hillside Ordinance compliance can run 30-50% above an identical scope on a flat slab. Fixture tier, tile material, and whether we’re moving walls also shift the price. Under The Haven Standard, every quote is flat with a written scope; no change proceeds without a signed change order.

FAQs - Bathroom Remodeling in Tarzana

Yes, if the project triggers the LA Hillside Construction Ordinance - which happens when you relocate plumbing, add square footage, or alter load paths on a hillside lot. A cosmetic replacement of fixtures in the same location may not trigger it, but moving a shower drain or adding a linear drain often does. We verify your lot classification and the specific scope against the ordinance before quoting, so the geotechnical cost is in the written price, not a mid-project surprise. Call (213) 221-0788 and we’ll check your address against the trigger criteria at no charge.
We map the existing drain path against the slope-stability setback and retaining-wall load line before we touch concrete. In a 1965 hillside ranch above Ventura Boulevard, our crew had to pull the slab, confirm the drain path with a deputy inspector, and run the new rough-in on the correct side of the load line before framing a frameless glass walk-in with a linear drain. The geotech report was folded into the plan set, and the inspection sign-off followed. We document the drain path photographically and include the findings in your written scope. Call (213) 221-0788 to schedule a site review.
On flat valley-floor homes, standard plan check applies - plumbing, electrical, and structural review, typically 2-4 weeks. On hillside lots south of Ventura, the permit triggers Hillside Construction Regulations review, adding geotechnical analysis, slope-stability certification, and Title 24 fire-resistive material specs before plan check even starts. That adds weeks and thousands in pre-permit costs that flat-lot jobs never see. We identify which path your project takes before you sign, so the permit timeline and cost are written into your quote. Call (213) 221-0788 for specifics on your property.
Yes, and we plan for it. Tarzana’s 100°F-plus summer days accelerate curing times for thinset, grout, and caulking, so we adjust sequencing and specify UV-stable exterior sealants on any bathroom vent or window penetration. The Santa Ana wind corridor through Tarzana’s south hills means temporary bracing requirements when roof or wall sections are opened, and we source frameless glass rated for those wind loads. We don’t treat climate as a scheduling footnote - it’s a material and labor spec that goes into your written quote. Call (213) 221-0788 to discuss timing for your project.
We investigate before we quote, not after we start. That means verifying lot classification against the Hillside Construction Ordinance, mapping drain paths against slope-stability setbacks, photographing slab conditions, and specifying every material and labor line item in the written scope. Under The Haven Standard, no work proceeds on a change until the change order is signed - which means we have every incentive to scope completely upfront. Our projects finish within a few percent of the agreed price because the number is built on verified conditions, not assumptions. Call (213) 221-0788 for a written quote that holds.
Call (213) 221-0788 to schedule your free estimate. We’ll review your bathroom, verify your lot conditions, and deliver a written flat price with a written scope and warranty - before anyone picks up a tool.
