Plant Prefab Bathroom Remodeling: The Fort Lauderdale Owner’s Guide
A full Plant Prefab bathroom remodel in Fort Lauderdale typically runs $9,000 – $28,000 installed, depending on whether you’re refreshing a guest bath or rebuilding a primary suite down to the studs. We stock and install bathroom fixtures, vanities, shower systems, and trim that match Plant Prefab build specs, and we can usually start within two weeks of your written estimate. Most owners find us after living with a bathroom that never quite worked right: a vanity that’s swelling at the base from humidity, a shower pan that flexes, or fiberglass walls that have started to separate at the seams. Plant Prefab builds a tight envelope, but South Florida humidity finds every weak point eventually.
That’s a factual statement, not a knock on the product. Plant Prefab panels and fixtures are engineered for rapid assembly and dimensional consistency. But a bathroom is a wet room first and a design statement second. In Fort Lauderdale, where the air holds moisture 340 days a year, the gap between “prefab tolerances” and “South Florida reality” is where most failure happens. We’ve rebuilt enough of these bathrooms to know exactly where to look.
Which Plant Prefab Models This Applies To

Plant Prefab’s bathroom modules ship with fixtures and finishes specified at the factory, but the underlying plumbing rough-ins, waterproofing planes, and trim details follow standard residential dimensions. That’s the good news: your Plant Prefab bathroom accepts standard 60-inch vanities, 36-inch shower bases, and off-the-shelf Delta, Moen, or Kohler trim. The gotcha is in the panel-to-panel seams behind the tile. Those seams are factory sealed, but after eight or ten years of Fort Lauderdale humidity cycling, the sealant loses adhesion. We see this most on Plant Prefab’s LivingHomes series, where bathroom modules share a wall with the home’s exterior envelope.
Before calling, grab a photo of the module label, usually stamped on the inside of the vanity cabinet door or on the access panel behind the toilet. It shows the build date, plan number, and finish package. That tells us what era of Plant Prefab hardware you have before we set foot on the job. If the label is gone, we measure the rough openings and match from there. For fixtures, we stock OEM-spec Kohler, Moen, and Delta trim that drops into the factory valves. For cabinetry and counter surfaces, we run KraftMaid and Cambria lines, which hold up better in Florida humidity than the original laminate and MDF assemblies many Plant Prefab units shipped with. You don’t need an identical replacement. You need one that won’t fail the same way twice.
Styles & brands we work with







Signs Your Plant Prefab Bathroom Remodeling Is Failing
- Swelling or bubbling at the vanity base. MDF and particleboard cores wick moisture from the floor upward. If the toe kick looks puffy or the doors scrape the frame, the substrate is already compromised. This is the most common Plant Prefab bathroom failure we see in Fort Lauderdale.
- Silicone pulling away from the shower pan edges. Factory sealant has a useful life. When it shrinks and cracks, water gets under the pan and starts working on the subfloor. You won’t see the damage until the tile outside the shower starts cracking.
- Soft spots in the floor outside the shower. Water that escapes the pan travels under the vinyl or tile. A spongy floor means the substrate is gone. Don’t wait on this one.
- Mildew smell that returns after cleaning. Persistent odor means moisture is trapped behind a surface, not on it. In Fort Lauderdale’s heat, that trapped moisture supports mold growth inside the wall cavity within weeks.
- Cracks along the ceiling line or at panel joints. Plant Prefab modules settle slightly after installation. Hairline cracks are normal. Cracks wider than a dime, or cracks that reappear after patching, point to movement behind the finish.
Replacement Cost & What’s Included

For Fort Lauderdale, here’s what you’re looking at in real dollar terms:
- Full Plant Prefab bathroom gut and rebuild: $9,000 – $28,000, depending on size, fixture grade, and what we find behind the walls once we open them up.
- Shower replacement only (pan + walls + waterproofing + trim): $3,000 – $8,500.
- Vanity and countertop replacement: $800 – $3,000 for the vanity, plus $2,000 – $6,500 for the countertop, installed.
- Tub-to-shower conversion: $3,500 – $10,000, which includes removal, new drain relocation if needed, waterproofing, and tile or solid-surface walls.
Every one of these prices is written down before we start. Not a verbal ballpark. A line-item written price, delivered before a single tool comes off the truck. What drives the range on a Plant Prefab bathroom specifically is what’s behind the factory finishes. If the waterproofing is intact, we’re doing a cosmetic refresh and the price lands low. If the shower pan leaked and the subfloor needs cutting out, the labor goes up. You see the difference on the estimate, not as a surprise later.
All work carries our 365-Day Done Right Promise: if something isn’t right within a year of completion, we make it right at no cost to you. That’s written on every contract, in plain language.

AfterDIY or Call Us?
Here’s the honest split. You can safely do this: remove and replace a vanity if the plumbing lines are in good shape, swap a fixture trim kit, re-caulk visible seams. Those are homeowner-level tasks. Where DIY goes wrong on Plant Prefab bathrooms is anything involving the waterproofing plane. The panel system in your bathroom is only as good as the sealant at every seam and penetration. If you strip tile to the panel and don’t re-seal the seams correctly, you’ll get a new shower that leaks the same way the old one did. Water damage in a wall cavity doesn’t announce itself. By the time you see it, you’re paying for structural repair on top of the bathroom work.
This isn’t high-tension garage springs or live electrical, so no dramatic safety warnings here. But waterproofing failures are the Florida version of a slow leak, and they cost more the longer they sit. If you’re uncertain about what’s behind the tile, call us at (754) 354-3720. Isaac Pruett will walk the job himself, open an access point if needed, and tell you what we found, what it takes to fix it, and what it will cost, before we touch a thing.

FAQs

The original factory bathroom in a Plant Prefab home typically needs meaningful work by year 8 to 12 in Fort Lauderdale’s humidity. With proper waterproofing and ventilation, a rebuilt bathroom should go 20-plus years before the next major renovation.
Yes, in many cases. We replace single showers, vanities, or failed waterproofing planes without tearing out the whole room. We’ll tell you plainly if partial work makes sense or if the damage has spread far enough that a full rebuild is actually cheaper in the long run. Call (754) 354-3720 and we’ll assess it honestly.
Most Plant Prefab bathroom projects in Fort Lauderdale run five to ten working days from demo to final caulk, depending on scope. A shower-only swap is usually three to four days. You’ll get a written schedule alongside your written price before we start.
