How Our Orange County Bathroom Remodel Works

Step 1 — Design & Technical Audit

We evaluate your existing space, plumbing infrastructure, and electrical layout to ensure your vision for a spa-like retreat is technically feasible and perfectly planned.

Step 2 — Permitting & MEP Prep

As a licensed Class B contractor, we handle all city permits and complex MEP work. Whether it’s relocating a drain for a freestanding tub or upgrading electrical, we do it safely and to code.

Step 3 — Waterproofing & Tile Work

We build a bulletproof foundation using advanced waterproofing systems. Our team then expertly installs custom tile, seamless glass showers, and premium semi-custom vanities with flawless geometry.

Step 4 – Fixtures, Finishes & Final Installation

The final phase involves installing luxury plumbing fixtures, statement lighting, and custom mirrors. We deliver a pristine, turnkey bathroom with zero-tolerance execution.
