Why Barrett & Sons Construction Is Diamond Bar’s Preferred Bathroom Remodeling Company
We’re the Bathroom Remodeling crew that puts the name on the truck, not a franchise that sends strangers to your door. Tom Barrett founded this company in 1998, and his sons run the crews. When you hire us in Diamond Bar, you’ll see the same faces from the first estimate through the final inspection. You can look up Tom’s name, address, and license number before you sign anything, and we’d actually encourage you to do that.
Our Diamond Bar customers tell us the same thing over and over: they’ve been burned by a contractor who quoted one number on the phone and handed them a different bill at the door. That’s why every allowance and every scope change comes as a written change order before work moves forward. No surprises at the end, because an allowance that isn’t on paper is a surprise waiting for a date. And every job carries our 90-Day Done Right Promise: if it’s not done right, one call brings Tom back.
We know Diamond Bar’s hillside lots, the drainage challenges on sloping foundations, and the way the city’s building department reviews permits. That local knowledge saves you time and money, and it keeps the job moving when a flatter-city contractor would be scratching his head.
Our Bathroom Remodeling Services in Diamond Bar
Full Bathroom Remodeling
A full bathroom remodel in Diamond Bar means taking the space down to the studs and rebuilding it right. Homes off Diamond Bar Boulevard and up toward Summitridge were mostly built in the 1960s through the 1980s, which means original plumbing, original electrical, and often water damage hiding behind the tile. We handle the gut, the rebuild, the permits, and the inspections. You’ll get a written scope from day one, so you know exactly what’s included and what it costs.
Walk-In Showers & Shower Remodeling
Walk-in showers are among the most common requests we hear from Diamond Bar homeowners in their 50s, 60s, and 70s. A curbless entry with a built-in bench and grab-bar blocking makes the bathroom safer without making it feel institutional. We install frameless glass enclosures, custom tile pans, and fixtures you can actually name and look up. No mystery parts off a van.
Tub-to-Shower Conversion
Tub-to-shower conversion in Diamond Bar typically runs $3,500 to $10,000 depending on the size of the opening and the condition of the surrounding walls. Many of the original tubs in these tract homes are cast iron or steel, set on floors that have settled unevenly over 40 to 60 years. We check the subfloor, correct what needs correcting, and build the new shower so it drains properly on a sloped lot.
Vanities, Tile & Fixtures
Sometimes the bones of the bathroom are fine and what you need is a refresh: a new vanity, updated tile, a proper exhaust fan, and fixtures that don’t fight you every morning. We install vanities with solid construction and named brands, lay tile on properly prepped surfaces, and make sure the ventilation is right for a room that sees real humidity. In Diamond Bar’s inland heat, a bathroom without proper ventilation is a mold problem waiting to happen.

Common Bathroom Remodeling Problems We See in Diamond Bar Homes
- Sloping floors and uneven subfloors. Diamond Bar’s hillside lots are built on expansive clay soil that swells and contracts with the seasons. We regularly open up a bathroom off Grand Avenue or near the Summitridge area and find the floor has settled a half-inch or more, which means the old tile cracked and the tub no longer drains correctly.
- Forty-year-old drainage pipes. The original cast-iron and galvanized pipes in these 1960s-1980s tract homes are entering failure cycles simultaneously. We’ve pulled out bathroom drains in Diamond Bar that were nearly closed off from decades of mineral buildup and rust.
- Hillside moisture issues. Bathrooms on the downslope side of a Diamond Bar home deal with groundwater pressure that flat-lot homes never see. If the original waterproofing was marginal, the wall framing behind the shower can be rotting even when the tile looks fine.
- Inadequate ventilation. Many original Diamond Bar bathrooms have a single small window and no exhaust fan at all, or a fan that vents into the attic. We correct this on nearly every remodel because the inland heat and Santa Ana conditions make trapped moisture a real problem.
Pricing for Bathroom Remodeling in Diamond Bar, CA
A full bathroom remodel in Diamond Bar runs $9,000 to $28,000. A small bathroom remodel starts around $5,000 and typically lands between $5,000 and $12,000.

The condition of the subfloor, the quality of fixtures you choose, whether we’re moving plumbing, and whether the city requires additional engineering review on a hillside lot.
