A full bathroom remodel means the room comes down to the studs — sometimes to the slab — and every system inside it gets touched: plumbing, electrical, ventilation, waterproofing, and every finish surface. It’s a different project than swapping a vanity or converting a tub, because once the walls are open, every downstream decision (where the drain sits, how the exhaust fan is ducted, what’s behind the tile) gets made at once instead of patched around later.

Most South Florida homes are slab-on-grade construction, which changes how a full remodel actually runs. Moving a toilet or shower drain means cutting concrete, not just repositioning a stud wall, so layout decisions get locked in early rather than adjusted mid-project. Elbaz Construction scopes full remodels as a single coordinated build across plumbing, electrical, and structural trades — not a string of subcontractors working off separate assumptions.

Because the room is fully open, a full remodel is also the one time to fix problems a smaller project can’t reach — old cast-iron drain lines, undersized exhaust ducting, water-resistant (not waterproof) backer board hiding behind decades-old tile. Those get addressed once, correctly, instead of getting sealed back up behind new finishes.

Full remodels in Miami-Dade, Broward, and Palm Beach typically require a building permit plus separate plumbing and electrical permits, since the scope almost always includes fixture relocation, new circuits, or both. Florida’s 2026 homeowner permit-waiver law (HB 803) lets single-family owners skip a permit on small projects under $7,500 — but plumbing, electrical, structural, and mechanical work are carved out of that waiver regardless of cost, and a full bathroom remodel touches all four. In practice this means the standard inspection sequence applies: rough plumbing, rough electrical, and a final inspection, with tile/waterproofing verification required by some local jurisdictions before walls close.

A full remodel is also the only point where exhaust ducting, electrical circuits, and future-proofing get planned rather than inherited. Florida’s mechanical code requires bathroom exhaust to vent directly outdoors — never into an attic or soffit — at a minimum of 50 CFM intermittent, and every bathroom receptacle needs to be on a dedicated 20-amp GFCI circuit. It’s also the cheapest point in the room’s life to add wall blocking behind the tile for future grab bars, even if no one in the household needs them yet — reopening finished tile later to add blocking costs far more than building it in now.

• Layout changes — Relocating the toilet, shower, or vanity drain means cutting and repouring the slab, which adds real cost and multiple days of curing time beyond the finish work.
• Material tier — Tile, countertop, and fixture selections span an enormous price range and are the single biggest lever on total cost.
• Room size — More square footage means more tile, more waterproofing membrane, and more labor hours, though small bathrooms often run higher per square foot due to fixed costs.
• Hidden conditions — Rotted subfloor, deteriorated drain lines, or mold behind old tile surfaces only once demo starts and can shift the budget.
• Fixture count and complexity — A double vanity, separate water closet, or upgraded shower system all add plumbing and electrical scope beyond a single-vanity, single-fixture layout.
• Permit and inspection complexity — Multi-trade permitting (building, plumbing, electrical) with sequential inspections adds calendar time and coordination cost that a cosmetic-only update doesn’t carry.
