Quick answer: Franco BuildWorks remodels bathrooms throughout Santa Fe, TX and the 77510/77517 area. In this humid Galveston County climate we build showers on a real waterproof membrane, plan around slab plumbing and aging galvanized lines, and factor septic capacity whenever a project adds a bathroom rather than simply refreshing an existing one.
This page covers bathroom remodeling for Santa Fe, TX homeowners. For the full step-by-step guide, see our Bathroom Remodeling service page — or explore all our work in Santa Fe.
Why waterproofing comes first in a Santa Fe bathroom
The single most important part of a Santa Fe shower is the part you never see. In a climate this humid, a shower that only relies on tile and grout to keep water out will eventually leak into the wall cavity and the framing, and the failure is slow and hidden. That is why a proper build uses a dedicated waterproof membrane — a liquid-applied coating like a red waterproofing membrane or a bonded sheet system — over cement backer board, not over ordinary moisture-resistant ‘green’ drywall.
Just as important is the shower floor. A tiled shower pan needs a correct pre-slope to the drain so water actually leaves the assembly instead of sitting under the tile. When these steps are skipped, you get mildew smells, loose tile, and rotted framing a few years down the line. We build the waterproofing to be inspected and photographed before the tile goes on, so you can see it was done right.
The plumbing you can’t see: cast iron, galvanized, and the slab
Bathrooms in Santa Fe’s 1970s and 1980s homes often still carry the original cast iron drain lines and galvanized steel supply lines. Cast iron corrodes and scales from the inside; galvanized supply gradually chokes down and drops your water pressure. When we open a wall for a remodel, it is worth looking honestly at what is behind it, because replacing tired pipe while the wall is open is far cheaper than doing it later.
Because most of these homes are slab-on-grade, moving a toilet flange or relocating a shower drain means cutting and trenching the slab through the same expansive clay the rest of the house sits on. We are candid about which fixture moves are simple and which ones require breaking concrete, so your layout choices are made with the real cost in view.
Adding a bathroom versus remodeling one — the septic question
There is a big difference between updating a bathroom that already exists and adding a new one. Many Santa Fe properties on larger lots run on on-site septic systems that were sized, at permit time, for a specific number of bedrooms and fixtures. Adding a full bathroom increases the design flow, and that can push an older system past what it was permitted to handle.
On-site sewage facilities here are regulated by the Galveston County Health District, and adding a bathroom can require review or a system modification. We bring this up before demolition so the project is planned around reality rather than around a hopeful assumption that the existing system will simply absorb the extra load.
Ventilation and mold in a coastal climate
Santa Fe bathrooms live in high ambient humidity for much of the year, so the exhaust fan is not a detail — it is a system. A fan that vents to the outside through the roof or soffit, sized for the room and actually used, pulls shower moisture out before it condenses on walls and grout. A fan that dumps into the attic, or no fan at all, is a recipe for the mildew that keeps coming back no matter how often you clean it.
Alongside ventilation, mildew-resistant coatings and paints in the wet zones help, but they are a supporting cast, not the star. If mildew is a recurring problem in your bathroom, the fix is usually air movement and waterproofing done correctly, not another bottle of cleaner.
Aging in place on Santa Fe’s single-story homes
A lot of Santa Fe is single-story ranch homes on generous lots, and many homeowners here intend to stay put rather than move. That makes the bathroom a natural place to plan ahead. Converting a cramped tub-shower into a curbless or low-threshold walk-in shower, adding solid blocking in the walls for future grab bars, and widening a doorway are all easier to do while the room is already opened up.
None of this has to look clinical. In most cases we can build a walk-in shower and comfort-height fixtures that simply read as a clean, current bathroom while quietly making the room work for the long haul.
Permits and how we sequence the work
As with kitchens, whether your bathroom needs a City of Santa Fe permit depends on whether you are inside the city limits or in unincorporated Galveston County, and on the scope of plumbing and electrical work involved. We help you understand which permits typically apply and handle them where required.
We sequence a bathroom so the waterproofing and rough-in are done and verified before anything gets covered, protect adjacent flooring and rooms during demolition, and keep you informed as pipes and framing are revealed. The goal is a bathroom that is dry inside the walls, not just pretty on the surface.
Bathroom Remodeling in Santa Fe: FAQ
What goes behind the tile in a Santa Fe shower — greenboard or cement board?
Moisture-resistant ‘green’ drywall is not appropriate behind shower tile. A durable shower uses cement backer board with a dedicated waterproof membrane over it. In this humid climate, that membrane is what actually keeps water out of your framing; tile and grout alone are not waterproof.
Can you convert my tub into a walk-in shower?
In most Santa Fe homes, yes. It typically involves removing the tub, adjusting the drain location, and building a properly sloped, waterproofed shower pan. On a slab foundation, moving the drain means cutting concrete, so we will explain the specific scope for your bathroom before you decide.
Will my septic system handle adding a second bathroom?
Not always. On-site septic systems are permitted for a set design flow, and a new bathroom increases that load. The Galveston County Health District regulates these systems, and adding a bathroom can require review or modification. We flag this during planning.
Why does mildew keep coming back in my bathroom?
It is almost always a ventilation and waterproofing issue, not a cleaning issue. A properly sized exhaust fan vented to the outside, plus correct waterproofing behind the tile, addresses the moisture at the source, which is what recurring mildew in Santa Fe’s humidity usually needs.
Do I need a permit to remodel a bathroom in Santa Fe?
It depends on your location and scope. Plumbing and electrical changes inside Santa Fe city limits generally require a City of Santa Fe permit; unincorporated Galveston County differs. We confirm what applies to your address before starting.
