Phase 1: Design and Selections
Royal Custom Construction begins every primary bathroom renovation with a 3D Interior Design service, including space planning, fixture selection, material samples, and photo-realistic renderings. Selections finalized before construction begins prevent the single largest source of delays and budget overruns: mid-project changes.
Phase 2: Engineering, Permits, and HOA Approval
Most primary bathroom renovations in South Florida require a plumbing permit and electrical permit at minimum. Structural changes or window relocations require building permits. HOA-governed properties need architectural review approval. We handle the full submittal in parallel with design finalization.
In Miami-Dade and Broward (HVHZ counties), any window replacement requires NOA-approved impact products and additional inspections. Palm Beach follows Florida Building Code 8th Edition without the HVHZ overlay.
Phase 3: Demolition and MEP Rough-In
Demolition typically takes 2 to 4 days. Plumbing, electrical, and HVAC rough-in (mechanical, electrical, plumbing) follows over 1 to 2 weeks, with rough-in inspections by the local building department before any walls are closed up. This is the highest-stakes phase for quality — what happens here is hidden but determines long-term performance.
Phase 4: Finishes Installation
Drywall, tile, cabinetry, stone surfaces, glass enclosures, lighting, plumbing fixtures, paint, and millwork — the finish phase typically runs 3 to 5 weeks. Material lead times (custom cabinetry, imported stone) often drive the schedule. Owner-selected items should be ordered during the design phase to land on-site in time.
Phase 5: Final Inspection and Walkthrough
Final inspections by the building department verify code compliance. Endless Life Design performs an internal punch-list inspection before the client walkthrough, then a joint walkthrough with the homeowner. Any final adjustments are completed within one week before project close-out and warranty registration.

The Design Freeze Before the First Hammer
The selections lock before the demolition starts, with every tile, fixture, and finish decided and documented so the construction never waits on a choice, the lead times triggered the day the design freezes, and the changes after the freeze priced as the disruptions they are, the decisiveness built into the schedule, the renovation moving fast because its thinking was finished before its breaking began.
The renovation moves fast because its thinking was finished before its breaking began. Endless Life Design freezes designs before demolition. Call (305) 680-3283 for projects that never wait on a choice.
The Boxes That Must Land Before Demo Starts
The materials arrive before the mess, with the tile, fixtures, and glass on site or confirmed in transit before the old bathroom comes apart, the household never left without a bathroom because a container sat in a port, and the schedule's promises backed by inventory rather than tracking numbers, the procurement gate enforced without exception, the demolition beginning only when the rebuild's ingredients already exist.
The demolition begins only when the rebuild's ingredients already exist. Endless Life Design stages materials before the breaking starts. Call (305) 680-3283 for remodels that never stall mid-gut.
The Slab Trenched for the New Drain
The layout change runs through concrete, with the relocated shower and fixtures requiring trenches cut, drains repositioned, and the slab restored to carry tile as if never opened, the routing planned against the structure below, and the patches compacted and poured to specifications rather than convenience, the heaviest day of the project executed precisely, the new layout standing on concrete work nobody will ever see again.
The new layout stands on concrete work nobody will ever see again. Endless Life Design cuts and restores slabs to specification. Call (305) 680-3283 for relocations done right beneath the tile.
The Rough-In Week Behind the Walls
The trades take turns inside the cavity, with the plumbing, electrical, and ventilation roughed in sequence while the walls stand open, the valves set to the exact heights the finished design dictates, and the blocking installed now for every grab bar, niche, and accessory later, the invisible week run with the most coordination of the project, the finishes succeeding because the skeleton beneath them was sequenced correctly.
The finishes succeed because the skeleton beneath them was sequenced correctly. Endless Life Design runs the rough-in week in proper order. Call (305) 680-3283 for walls closed over coordinated work.
The Seven Inspections a Bathroom Can Collect
The permit checks in repeatedly, with the rough plumbing, rough electrical, framing, and their final counterparts each requiring the inspector's pass before the next stage hides the work, the schedule built around the visits rather than surprised by them, and the approvals accumulating in the file that closes the permit cleanly, the oversight absorbed into the rhythm, the bathroom finished with every signature it owed collected on time.
The bathroom is finished with every signature it owed collected on time. Endless Life Design schedules remodels around their inspections. Call (305) 680-3283 for permits that close without drama.
The Glass Measured Only After the Tile Cures
The enclosure waits for reality, with the heavy glass templated against the finished, cured tile rather than the drawings, the out-of-plumb truths of every real wall captured in the measurement, and the fabrication started only when the openings exist to be measured, the patience built into the sequence, the panels arriving weeks later to fit perfectly because they were measured from truth, not intention.
The panels arrive weeks later to fit perfectly because they were measured from truth, not intention. Endless Life Design templates glass at the right moment. Call (305) 680-3283 for enclosures that fit the first time.
The Vanity Stone Templated Like the Kitchen's
The counter earns the same rigor, with the vanity tops templated from the installed cabinets, the faucet and sink cutouts located to the actual plumbing, and the fabrication sequenced so the stone lands when the room can receive it, the small surface treated with full-size discipline, the vanity finished with edges and cutouts that meet their hardware exactly.
The vanity is finished with edges and cutouts that meet their hardware exactly. Endless Life Design templates every stone surface properly. Call (305) 680-3283 for tops that fit like they were grown there.
The Shutoffs Replaced While Everything Is Open
The opportunity hides in the open walls, with the aging angle stops, supply lines, and accessible valves replaced during the remodel at a fraction of their emergency cost, the future leak points retired while retiring them is trivial, and the home's plumbing exiting the project younger than it entered, the cheap insurance purchased at the perfect moment, the bathroom rebuilt with no old weak link left behind the new finishes.
The bathroom is rebuilt with no old weak link left behind the new finishes. Endless Life Design replaces the small parts while access is free. Call (305) 680-3283 for remodels that renew everything they touch.
The Drywall Returned by the Plaster Trade
The walls are healed by specialists, with the patches, returns, and ceilings skimmed flat by finishers rather than approximated by whoever was nearby, the texture matched so the repair vanishes into the original, and the paint landing on surfaces prepared to disappear, the final smoothness treated as its own trade, the bathroom reading as seamless because its last imperfections were erased by the right hands.
The bathroom reads as seamless because its last imperfections were erased by the right hands. Endless Life Design finishes walls with the trade they deserve. Call (305) 680-3283 for surfaces that show no history.
The Door Undercut That Feeds the Fan
The exhaust needs air to exhaust, with the door's undercut or transfer path sized so the fan can actually pull replacement air while the room is closed, the powerful fan in a sealed room moving almost nothing, and the small clearance specified rather than left to the carpenter's habit, the airflow designed as a loop, the moisture leaving efficiently because the room could breathe in while it breathed out.
The moisture leaves efficiently because the room could breathe in while it breathed out. Endless Life Design designs the airflow loop fans depend on. Call (305) 680-3283 for ventilation that truly works.
The Final Walk With the Water Running
The handover happens under flow, with every valve, drain, and seal exercised in front of the owner, the temperatures verified at the tempering settings, the enclosure checked for escape at full spray, and the small adjustments made on the spot while the technicians stand there, the commissioning performed rather than presumed, the bathroom accepted in operation, the first real shower preceded by a rehearsal that proved everything.
The first real shower is preceded by a rehearsal that proved everything. Endless Life Design hands over bathrooms tested under water. Call (305) 680-3283 for finishes proven before the keys.
