Quick answer: Franco BuildWorks remodels bathrooms throughout Porter and 77365, from primary suites in Oakhurst and Valley Ranch to worn baths in the older homes near the San Jacinto. In this humid, flood-aware corner of Montgomery County, we build showers around a real waterproofing membrane, plan for septic capacity where it applies, and detail wet areas to last.

The bathrooms Porter homes tend to have
In the older parts of Porter — the ranch and traditional homes from the 1960s to 80s off Ford Road and near the East Fork San Jacinto — original bathrooms are usually small, with mud-set tile, dated vanities, and tub surrounds that have quietly been letting water into the wall for years. In the master-planned communities like Oakhurst, Auburn Trails, and Valley Ranch, the bathrooms are newer but often builder-standard: a fiberglass tub-shower, a basic vanity, and a layout ready to become something better.
A common Porter project is converting a builder tub-shower into a larger tile or low-threshold shower, or opening a cramped older bath into a proper primary suite. Which one you’re doing changes everything downstream — the drain location, the waterproofing, and whether walls or plumbing have to move.
Waterproofing is the entire job here
In a humid Gulf Coast bathroom, the tile is the finish, not the waterproofing. A shower that lasts depends on what’s behind the tile: a bonded waterproof membrane, such as a liquid-applied coating (RedGard-type) or a sheet membrane system (Schluter Kerdi-type), over a proper substrate, with a correctly built sloped pan and the right drain. Tile and grout are not waterproof on their own — they manage water, and the membrane stops it.
This matters more in Porter than in a dry climate because ambient humidity keeps wall cavities from drying out quickly. When a shower is built without a continuous membrane, the failure shows up as loose tile, dark grout lines, and eventually mold and rotted framing. We build the wet area as a waterproof assembly first and treat the tile as the last, visible layer.
- Bonded waterproof membrane (liquid-applied or sheet) behind all wet-area tile
- Sloped, correctly drained shower pan — not just backer board and thinset
- Ventilation sized to actually clear moisture in a closed-up, humid house
Adding a bathroom? Check the septic before the tile
Adding a bathroom — a common ask when finishing space or expanding a primary suite — adds fixture load. In the MUD-served communities of Porter that’s mostly a plumbing question. But many older and rural 77365 properties run on a private septic system, and adding bedrooms or bathrooms can exceed what the existing system and drain field were sized for. In Montgomery County, meaningful changes to septic load can involve environmental-health review and, in some cases, system modifications.
We raise this early because it’s the kind of thing that’s cheap to plan around and expensive to discover after framing. If you’re on a well and septic, the bathroom count is part of the engineering, not just the design.
Aging-in-place work in Porter’s 55+ communities
Porter has a real over-55 population, including the active-adult sections around Oakhurst. A lot of bathroom work here is about staying in a home comfortably: curbless or low-threshold showers, blocking in the walls for grab bars, comfort-height fixtures, slip-resistant floor tile, and better lighting.
Done right, these features read as clean design rather than medical equipment. The key detail people miss is the wall blocking — grab bars have to anchor into solid backing installed during the remodel, so we plan those locations before the walls close up, even if the bars go in later.
This area remembers its floods
Porter and neighboring Kingwood took serious water in the 2016 Tax Day flood and again during Hurricane Harvey in 2017 along the San Jacinto. A bathroom near a slab that has flooded — or simply a ground-floor bath in a humid house — benefits from moisture-tolerant choices: cement or foam backer instead of paper-faced board, rigid-core or tile flooring instead of moisture-sensitive materials, and mildew-resistant paint. These are small decisions at build time that pay off in a climate that never really dries out.
Permits and how Franco works here
Porter is unincorporated Montgomery County, so a straightforward bathroom remodel typically isn’t reviewed by a city building department. Plumbing, gas, and electrical work should still meet code, septic changes can trigger county review, and floodplain rules can apply to homes in the mapped San Jacinto flood hazard areas. HOA or deed restrictions may govern anything that touches the exterior.
Franco BuildWorks is a service-area remodeler covering Porter and the surrounding communities. On a walkthrough we typically check the existing waterproofing, the drain and vent layout, whether you’re on septic or MUD, and how long you plan to stay in the home, then describe the scope plainly before any tile comes off the wall.
Bathroom Remodeling in Porter: FAQ
What actually makes a shower waterproof?
The membrane behind the tile, not the tile itself. A lasting shower uses a bonded waterproof membrane — liquid-applied or sheet — over a proper substrate, with a sloped, correctly drained pan. Tile and grout manage water; the membrane stops it. In Porter’s humidity, skipping that step is the most common reason showers fail.
Can I add a second bathroom if I’m on septic?
Sometimes, but it depends on your system. Many rural Porter properties run on a septic system sized for the original bathroom count. Adding fixtures can exceed that capacity and, in Montgomery County, can involve environmental-health review. We look at this before design so a new bathroom doesn’t outrun your drain field.
Do you build walk-in or grab-bar showers for older homeowners?
Yes. Low-threshold and curbless showers, in-wall blocking for grab bars, comfort-height fixtures, and slip-resistant floors are common requests, especially in Porter’s active-adult communities. The important part is installing solid wall backing during the remodel so bars can be anchored securely whenever they’re needed.
My old shower has loose tile and dark grout — what’s going on?
That’s often water getting behind tile that was set without a continuous waterproof membrane, which shows up faster in this humidity. In most cases the fix is to remove the wet-area tile, correct or replace the membrane and pan, and re-tile — patching over the surface rarely lasts.
Do I need a permit for a bathroom remodel in Porter?
A basic remodel in unincorporated Montgomery County generally isn’t permitted through a city. But code still applies to plumbing, gas, and electrical work, septic changes can require county review, and homes in mapped floodplains near the San Jacinto may be subject to floodplain rules. We’ll point out where a step applies rather than assume none do.
