Interior Renovations

Bathroom Remodeling

Waterproofed correctly, finished beautifully, done in weeks, not months.

Bathrooms are the single most common place we find other contractors' shortcuts: tile set over unprepared substrate, no proper pan slope, missing waterproofing membrane, vent fans dumping humidity into the attic. We rebuild bathrooms from the studs out so the finish you pay for is still perfect ten years from now.

Typical timeline

2–4 weeks per bathroom

Typical investment

Most projects land between $12,000 and $45,000 depending on size and finishes

How we approach it

Where the work behind the wall matters most

In South Florida, a bathroom remodel is more than just a cosmetic upgrade. Humidity and salt air mean that what happens behind your tile is actually more important than the tile itself. We see too many bathrooms where contractors skipped the waterproofing membrane or used the wrong substrate, leading to mold and structural rot within just a few years.

We build bathrooms from the studs out. This ensures that the plumbing is current, the shower pan is perfectly sloped to the drain, and a continuous waterproofing barrier protects your home from moisture intrusion. Whether it is a master suite retreat or a high-traffic guest bath, we focus on the engineering first.

Our process is designed to minimize the time you are without your bathroom. By staging all materials before demolition starts and sequencing our trades without gaps, we turn projects around in weeks, not months, without ever cutting corners on the drying time required for a perfect finish.

Example project

Master suite transformation with curbless entry

Boca Raton, FL3 weeks

The challenge
A 1990s master bath with a large built-in tub and a tiny, dark shower stall that had developed a slow leak into the subfloor.
What we did
We removed the tub entirely to create a massive walk-in shower with a curbless entry and a custom linear drain. We replaced the rotted subfloor and installed a full-room waterproofing system.
The result
The bathroom feels twice the size, the leak is permanently solved, and the client has a modern, accessible space that adds significant value to the home.

Illustrative example based on typical jobs of this type.

Standards we hold

  • Every shower pan undergoes a 24-hour flood test before tiling
  • We use Schutler-Kerdi or equivalent full-envelope waterproofing systems
  • All plumbing is updated to current South Florida building codes
  • Dust containment walls and HEPA air scrubbers are used on every job
  • Tile layouts are dry-fitted first to ensure perfect alignment and cuts

Client feedback

Referred, again and again

“They gutted and rebuilt two bathrooms and our kitchen while we lived in the house. Every day the site was clean, every question got answered the same day, and the final number matched the estimate.”
Daniel R. · Fort Lauderdale, FL · Kitchen + 2 bathroom remodel
“We had water damage behind a wall that two other contractors misdiagnosed. 12X found it in an hour, handled the drying, rebuilt the drywall, and dealt with the insurance paperwork.”
Melissa T. · Hollywood, FL · Water-damage restoration
“Pavers, a pergola, an outdoor kitchen, and turf, done in five weeks and permitted properly. Our backyard is the reason we stopped talking about moving.”
