Our crew serves Altadena neighborhoods from the foothills to the flats, and we scope every job as if our own family lived there.
Why Mason Remodeling Is Altadena’s Preferred Bathroom Remodeling Company
Mason Remodeling has been doing this work since 2004, and as a General Contractor in Altadena, our crews follow one process: every technician is background-checked, identity-verified, and introduced to you by name and photo before the visit. We call it the Threshold Standard, and it matters to homeowners who are home alone, parents with young kids, or anyone who thinks twice before opening the door to a stranger. Your crew shows up in a clean marked uniform, shows a photo ID badge at the door, and works with the same care we’d expect in our own homes.
We’re not new to Altadena. We’ve walked gutted bathrooms on Lake Avenue, scoped shower rework near Fair Oaks, and pulled permits for tub-to-shower conversions in the mid-century ranches off Lincoln Avenue. What we’ve learned is that Altadena homes demand more care at the rough-in stage than most people expect, and the quotes that ignore that reality are the ones that blow up mid-project. Ours don’t. Every project gets a written scope, a written price, and a 365-Day Done Right Promise: if the work isn’t right within a year of completion, we make it right at no cost to you.
Isaac Pruett leads our crew, and he’s particular about how a job gets scoped. No verbal estimates that grow on the final bill. No surprises hidden in allowances. Just a line-item price delivered before a single tool gets unpacked.
Styles & brands we work with
Shower Remodel in Altadena
A Shower Remodel in Altadena usually means more than swapping tile and a valve here, because so many of the town’s 1920s bungalows and 1950s ranches still carry cast-iron drains and original framing behind the shower walls. In a flatter, newer suburb, those same walls usually hide recent ABS plumbing. In Altadena, a shower remodel often starts with a subfloor inspection, because a slow leak that ran for years can soften plywood and rot joists before anyone sees a wet spot on the ceiling below.
What We Check Before Demolition
Before we touch tile, we confirm the drain type, test the framing for load-bearing issues, and look for moisture damage that would change the price if it went unnoticed. Then the written quote reflects what we found, not what we’re guessing at.
Shower Remodel Pricing in Altadena
A shower replacement in Altadena runs $3,000 – $8,500, while a full walk-in shower installation runs $4,500 – $12,000. The difference comes down to whether we’re keeping the existing drain location or moving it, whether waterproofing needs to be rebuilt, and what finish materials you choose.
Tub to Shower Conversion in Altadena
A Tub to Shower Conversion in Altadena is one of the smartest moves for an aging bungalow, and it’s a job where our local experience changes the quote. Many Altadena bathrooms built before the 1960s have cast-iron tub drains that do not align with modern shower bases, which means the conversion often includes repiping the drain and adding venting to meet current code. A contractor who doesn’t know Altadena homes will discover that on demolition day and hand you a change order. We write it into the scope up front.
When a Tub-to-Shower Conversion Makes Sense
If you’re stepping over a high tub wall every day, or if the tub is original to a 1930s house and the enamel is worn through, a conversion gives you a low-threshold entry and a more usable shower without expanding the room’s footprint.
Tub-to-Shower Conversion Pricing in Altadena
A tub-to-shower conversion in Altadena typically runs $3,500 – $10,000. The lower end covers a direct replacement with an acrylic base and basic fixtures; the upper end includes moving the drain, rebuilding the valve, adding code-compliant venting, and finishing with tile and a frameless glass enclosure.
Trusted Brands We Service in Altadena
We install and service fixtures and surfaces from Kohler, Moen, Toto, Grohe, Cambria, Silestone, and Caesarstone, plus cabinetry from KraftMaid and Wellborn. We keep common replacement parts in stock for Altadena jobs, which means a valve trim or a shower cartridge doesn’t add a week to the schedule. Through our specification-grade partnerships, we also have access to builders like Dvele and Cover when a bathroom remodel grows into a larger structural conversation. For most Altadena homes, that’s not the path, but it’s good to know the option exists without changing contractors.

AfterCommon Bathroom Remodeling Problems We See in Altadena Homes
- Cast-iron waste lines that have been underground since the Coolidge administration. Original 1920s pipes often look fine from the cleanout but crumble the moment we cut into them. We inspect early and price the replacement in the quote.
- Soft subfloors hidden under old tile. Slow shower pan leaks and wax ring failures quietly rot the plywood under Altadena bathrooms, especially in pre-1960 houses. We probe the floor before demolition and show you photos of what we find.
- Missing or inadequate venting. Many Altadena bathrooms were plumbed when code didn’t require the same vent sizing, so adding a proper vent stack changes the permit plan and the price. We handle it on paper before it becomes a wall-open surprise.
- Load-bearing walls behind the shower. In mid-century ranches, the wall behind the tub often carries ceiling joists or roof load. We identify it before we touch framing, and we never cut a load-bearing member without an engineered plan.

FAQs About Bathroom Remodeling in Altadena
Yes, for nearly every bathroom remodel that touches plumbing, electrical, framing, or the shower waterproofing, you’ll need a building permit from Los Angeles County, and your project must pass county inspection before the walls are closed. Skipping the permit to save a few weeks is the fastest way to fail a sign-off when the rough-in must be reopened. We pull permits on your behalf, schedule the inspections, and close walls only after the inspector signs off.
Most Altadena bathroom remodels land between $9,000 and $28,000, and the spread comes down to three things: what’s hiding in the walls and floors (rotted subfloor and cast-iron drains are common in pre-1960 homes), what fixtures you select (a Kohler shower system costs more than a basic valve trim), and whether the project requires moving plumbing or adding venting to meet code. We give you a written, line-item quote before any work starts. Call (803) 680-2547 for an exact number on your bathroom.
Yes, but only because we scope the surprise out first. In an Altadena home, that means checking the drain material, probing the subfloor, and confirming the venting plan before we write the quote. That way the $3,500 – $10,000 range you approve is the range you pay.
A standard bathroom remodel in Altadena takes three to six weeks once permits are issued, depending on whether drains are being relocated, venting is being added, or load-bearing walls need an engineered fix. Permitting with the county can add one to three weeks on the front end. We give you a calendar in writing, and we don’t promise same-day or emergency turnaround on planned construction work, because no one does it honestly.
Start with a written scope of work and clear allowances, and never accept a verbal estimate on work that will open your walls. In Altadena’s older homes, the lowest bid is often the one that treats a cast-iron drain or missing vent as an unpriced change order mid-demolition. Our price comes in writing before work starts, and the 365-Day Done Right Promise covers anything that isn’t right within a year. Call (803) 680-2547 for a free estimate and a quote you can hold us to.
