Fast, Reliable Bathroom Remodeling Across Mercedes
Bathroom remodeling in Mercedes, TX typically runs $9,000 to $28,000 for a full gut-and-replace, and most jobs take two to four weeks once permits clear. We do the work the same way whether we’re on a 1950s concrete block house south of 2nd Street or a newer build near the high school, which means the permit gets pulled before the first tile comes up, and every price change shows up as a written change order before a single nail moves. Call (877) 610-1318 and Tom or one of his sons will talk you through what your bathroom actually needs, not what a national call center thinks you should buy.
Why Barrett & Sons Construction Is Mercedes’s Preferred Bathroom Remodeling Company
Tom Barrett founded Barrett & Sons in 1998, and his name is on the side of the truck that shows up in Mercedes. His sons run the crews. You’ll see the same faces at the hardware store on Saturday that you saw at your house on Monday. That’s not a marketing line; it’s how we’ve operated for over 29 years.
Mercedes homeowners call us because we answer the phone with a live person, 24 hours a day, and because our Bathroom Remodeling team handles the permit process start to finish. We’ve worked in the 78570 area long enough to know that the inspector here will absolutely want to see wind-rated vent caps and damper documentation. Skip that, and you’re not getting a sign-off. We don’t skip it. Our license number is something you can look up yourself before you sign anything. Tom has always wanted it that way.
Our Bathroom Remodeling Services in Mercedes
We handle the full scope of bathroom work, but three services come up most often when we talk to homeowners in Mercedes.
Walk-In Shower Installation
A walk-in shower in Mercedes runs $4,500 to $12,000 depending on whether we’re working within the existing footprint or expanding the wall. On older concrete block homes, expanding a wall means we’re cutting into block that was never built to current wind-load standards. Under Mercedes’ adoption of the 2018 International Residential Code with Hidalgo County amendments, that new wall section must meet a 140 mph design wind speed. We handle the engineering and the inspection. Cheap quotes often leave that step out, and it shows up later.

Tub-to-Shower Conversion
Replacing a tub with a shower is our most requested job in Mercedes, priced from $3,500 to $10,000. Most local homes from the mid-century era were built with cast-iron tubs and plumbing that never had individual shut-off valves. We almost always find corroded drain lines and often a slab that’s moved at the flange. We address that before we close anything up.

Bathroom Vanity Installation
Vanity work runs $800 to $3,000 in Mercedes. It’s a quicker job, but the local wrinkle is the wall behind the vanity. In older homes with unpermitted electrical work, we need to verify what’s in that wall before we mount anything. We’ve seen enough aluminum wiring and ungrounded circuits in 78570 to know better than to assume.

Tile & Fixtures
We install Schluter waterproofing systems under tile in every shower we build, and we carry Grohe and Sterling fixtures into Mercedes homes because they hold up through the hard water and heat that define South Texas summers. Tile over gumbo soil needs a substrate that can move without cracking, and that’s exactly what Schluter’s uncoupling membranes are designed for.

Trusted Brands We Service in Mercedes
We install Schluter waterproofing systems in showers, Grohe fixtures and valves, and GAF roofing components where a bathroom remodel expands into vent work. Using brands you can look up matters to us because it matters to the kind of customer who lives in Mercedes. You shouldn’t have to wonder what was put behind your wall. We keep local parts supply relationships in the Rio Grande Valley, so when a Sterling shower valve fails or a damper needs replacement, we’re not waiting on a shipment from California.
Common Bathroom Remodeling Problems We See in Mercedes Homes
- Exhaust vents with no backdraft damper or wind-rated cap. The first strong South Texas wind event rattles the damper, and humidity from the shower condenses inside an uninsulated vent run. We’ve repainted ceilings in Mercedes where staining came from exactly this. The 140 mph wind-load requirement for vent caps is not optional here.
- Slab heave cracking tile grout. The black gumbo clay under Mercedes shrinks and swells through wet-dry cycles, and slab-on-grade bathrooms without a vapor barrier wick moisture straight up from the soil. We see tile grout crack within months when a new shower was installed without addressing the substrate movement.
- Plumbing with no shut-off valves. On older Mercedes homes, a bathroom fixture often ties directly into the main line with no way to isolate it. That’s a problem during a remodel and a problem later when one fixture fails. We add valves as standard practice.
- Unpermitted additions that complicate a new permit. Many homes in the 78570 area grew piecemeal over decades, with colonia-style additions and bathroom work done without permits. When we pull a permit for a new remodel, the city will want to see that prior unpermitted work is reconciled before sign-off. We handle that paperwork and the scope narrative.

FAQs - Bathroom Remodeling in Mercedes
If the tub-to-shower conversion alters plumbing or adds fixtures to an exterior wall, Mercedes requires the new wall section, exhaust vent, and any window opening to meet a 140 mph design wind speed under the 2018 IRC with Hidalgo County amendments. That means a wind-rated vent cap and damper are part of a compliant quote, and the inspector will check for them at sign-off. Call (877) 610-1318 to have us walk through what your specific job will need.
The shrink-swell clay under Mercedes moves slab foundations through every wet-dry cycle, and slab-on-grade bathrooms without a vapor barrier will wick moisture upward, cracking tile grout within months. We use uncoupling membranes from Schluter to isolate tile from that movement. If your slab has heaved at the toilet flange, we address drainage and leveling before any tile goes down. Call (877) 610-1318 for an exact assessment.
A change order is a written document that lists a change in scope, materials, or price and requires your signature before the work happens. In Mercedes, we issue one any time opening a wall reveals something the original quote didn’t cover: a rusted drain, unpermitted wiring, or foundation movement. You’ll never see a price change that didn’t first arrive on paper. Call (877) 610-1318 if you’ve been burned by verbal changes before.
You can apply to legalize unpermitted work in Mercedes, but the city will require you to open walls where needed so an inspector can see what was built. It usually costs more than pulling the permit upfront because you’re paying to uncover and then redo work. We pull permits before we start, and we stand behind the inspection sign-off with our 90-Day Done Right Promise. Call (877) 610-1318 to talk through your situation.
Under the 2018 IRC as adopted in Mercedes with Hidalgo County amendments, a new bathroom window or exhaust vent in a Risk Category II building must meet a 140 mph design wind speed. That means a rated vent cap with a functioning backdraft damper and documented installation. A contractor who skips that leaves an opening that can fail in a wind event, and an insurance adjuster may cite the absence of a permit and inspection record as grounds to deny coverage for water intrusion around that opening. Call (877) 610-1318 for a quote that includes the wind-load documentation.
