The first tile usually comes off easier than anyone expects. A few taps with a pry bar, a dull crack, and suddenly the wall behind a perfectly ordinary shower is on display for the first time in decades. That moment tends to split homeowners into two camps. Some see sound framing and dry drywall. Others see dark stains, soft wood and a pipe that looks like it belongs in a museum.
What’s behind the finish matters more than the finish itself, especially in a region where heat and humidity work on bathrooms every single day. Plenty of houses around the capital were built between the 1960s and the 1980s, and many of their bathrooms have been “updated” once or twice since with new tile laid straight over old problems.
Planning for what might turn up is the quiet difference between a smooth project and a stalled one. A good Banroog bathroom remodel starts with that assumption baked in, and Apex 360, the Tollway Drive company Perry Stephens founded in 2021, frames its work around taking a space from foundation to finish rather than simply swapping surfaces. Whoever does the work, though, the same hidden layers are waiting, and knowing them ahead of time changes how you budget, schedule and build.
Peeling the Room Back One Layer at a Time
Think of an older bathroom as a stack. Each layer either protected the one beneath it or quietly let it down. Here is roughly what comes to light as the room is opened up.
What the tile was telling you all along
Cracked grout lines, loose tiles near the floor of the shower and stains that never scrub out are not cosmetic quirks. They usually mean water has been slipping past the surface for years. In many older showers, tile was set directly over standard drywall or over a backer that was never sealed. Cement board, for instance, holds up to moisture but is not waterproof on its own. Without a membrane over it, water passes through and soaks into whatever sits behind.
Inside the wall cavity
Once the backer comes off, the framing tells the story. The bottom plate of the shower wall, where water collects and sits, is the most common spot for rot. Mold on the paper face of drywall is another frequent find, particularly on walls shared with closets where air barely moves.
South Louisiana adds a regional wrinkle. Formosan subterranean termites thrive in damp wood, and a slow leak inside a bathroom wall gives them exactly what they want. Finding termite damage during demolition is unsettling, but finding it now beats finding it after new tile is sealed over it.
Pipes nobody has seen in fifty years
Homes from this era often carry galvanized steel supply lines that corrode from the inside, gradually choking water pressure until the shower barely sputters. Drain lines are frequently cast iron, which can crack, scale or rust through along the bottom. Because so many local homes sit on concrete slabs, the drain under the tub or shower is buried in that slab, and a remodel is often the only practical chance to inspect it.
Shutoff valves are the small item people forget. Old multi turn valves seize up, and replacing them during the remodel costs very little compared with discovering they won’t close during an emergency.
The wiring and the air
Older bathrooms commonly lack GFCI protected outlets, which current code requires near water for good reason. Exhaust fans are another weak spot. Many were undersized from the start, and a surprising number vent straight into the attic instead of outdoors, pumping warm wet air into insulation and roof decking. A widely used rule of thumb calls for about one cubic foot per minute of airflow for every square foot of floor space in a typical bathroom, and the duct needs to reach the outside.
Materials that shouldn’t be disturbed casually
Homes built before 1978 may contain lead based paint, and some older vinyl flooring and adhesives may contain asbestos. Neither is a reason to panic, but both are reasons to test before demolition. The EPA’s Renovation, Repair and Painting Program explains the lead safe practices contractors are expected to follow when working in older homes, and it’s worth reading before any work begins in a pre 1978 house.
Why Surprises Belong in the Budget Before Day One
Hidden conditions are not really surprises if you plan for them. Many remodelers advise setting aside a contingency of roughly 10 to 20 percent of the project cost for older homes, and keeping that money untouched until the walls are open.
A thorough walkthrough before demolition narrows the unknowns. Useful questions to raise include the following.
- What are the supply and drain lines made of, and can any of them be seen from an access panel or the attic?
- Where does the exhaust fan actually vent?
- Has the home been tested for lead or asbestos, and if not, who will handle it?
- If the drain has to move, how much of the slab will be cut, and how long will that add?
- What happens to the schedule if rot or termite damage turns up?
Clear answers on paper make it far easier to approve changes quickly instead of leaving a gutted bathroom sitting idle for a week.
Building It Back So It Outlasts the Last One
The real payoff of opening everything up is the chance to rebuild the room correctly from the inside out.
Waterproofing comes first. Modern showers rely on sheet or liquid applied membranes over the backer board, wrapping walls, niches and benches, and tying into a properly sloped pan. A flood test, where the pan is plugged and filled with water for a period of time before tile goes down, confirms the system holds. Older showers often used a mortar bed over a liner, and that method can work well, but only when the slope and drain connections are right.
Layout changes happen at this stage too. Converting a tub into a walk in shower is one of the most requested updates, and on a slab home it usually means cutting concrete to reposition and resize the drain. Curbless entries, which many people choose with aging in mind, require recessing the shower floor so water still flows toward the drain. While the walls are open, adding solid blocking for future grab bars costs almost nothing and saves real trouble later.
Ventilation should be treated as part of the structure rather than an accessory. A properly sized fan ducted outdoors, ideally with a timer or humidity sensor, keeps the new room from slowly repeating the old room’s mistakes. Porcelain tile, well sealed grout and fixtures with accessible shutoffs round out a space built for a climate where moisture never takes a season off.
The Room That Comes Out the Other Side
A remodeled bathroom gets judged by how it looks on the day it’s finished, but its real test comes years later. Does the grout stay clean? Does the mirror clear quickly after a shower? Does the floor stay solid underfoot? Those answers were decided weeks earlier, inside the walls, when someone chose to fix what they found instead of covering it up again.
Going in expecting the unexpected is what makes that possible. The tile is the part you see every morning. Everything behind it is the part that decides whether you’ll be tearing it out again in fifteen years.
