A full bathroom remodel in San Diego typically runs 3 to 6 weeks depending on the scope. That timeline accounts for demolition, rough plumbing and electrical, waterproofing, tile installation, vanity and countertop fabrication, fixture setting, and paint. If you are moving walls, relocating the toilet drain, or adding a window, expect the longer end of that range because structural and permit work adds time.

The most common scope items we see in San Diego bathroom remodels include: tub-to-shower conversions (removing a 5-foot alcove tub and building a walk-in shower), full re-tile of walls and floors, vanity replacement with new plumbing connections, upgraded lighting and exhaust ventilation, new toilets, and replacement of aging supply lines and drain assemblies. In homes built before 1985, we frequently encounter galvanized drain piping that is partially corroded and needs replacement — this is not something you can skip and expect the remodel to last.

Permits are required through San Diego's Development Services Department anytime you move plumbing, add circuits, or change the structural layout. SDCC pulls all permits directly and coordinates the inspection schedule so you never have to meet an inspector yourself.

The number one reason bathroom remodels fail is inadequate waterproofing behind tile. Tile and grout are not waterproof — they are water resistant at best. Without a proper waterproofing membrane behind the tile, water migrates into the wall assembly, saturates the framing, and eventually causes mold, rot, and structural damage. We see this constantly when demoing bathrooms that were remodeled 10 or 15 years ago by contractors who skipped this step.

SDCC installs waterproofing on every shower and tub surround using either Schluter Kerdi sheet membrane or RedGard liquid-applied membrane, depending on the substrate and application. Kerdi is a polyethylene membrane that bonds directly to cement board and creates a vapor barrier behind the tile. RedGard is a liquid rubber membrane that gets rolled or sprayed onto cement board and cures to form a flexible waterproof layer. Both systems meet TCNA (Tile Council of North America) standards when installed correctly.

We also waterproof shower floors using a bonded mortar bed over Kerdi or a pre-sloped foam pan like Schluter Kerdi-Shower-ST. The floor has to slope toward the drain at a minimum of 1/4 inch per foot — this is code and it is non-negotiable. A flat shower floor is a shower that holds water against the membrane seams and eventually leaks into the subfloor below.

San Diego's hard water is a factor in every bathroom remodel. The city's water supply registers between 12 and 25 grains per gallon of hardness depending on your neighborhood and the source blend. That mineral content leaves calcium deposits on fixtures, glass, and tile over time. When selecting fixtures and finishes, this matters — polished chrome shows water spots immediately, while brushed nickel, matte black, and satin brass finishes mask mineral buildup and are easier to maintain in hard water conditions.

Ventilation is another San Diego-specific consideration, particularly in coastal neighborhoods where ambient humidity is higher year-round. California building code requires a minimum 50 CFM exhaust fan in bathrooms, but in homes near the coast — Pacific Beach, Ocean Beach, Point Loma, La Jolla — we recommend upgrading to 80-110 CFM rated fans with humidity sensors that turn on automatically. Proper exhaust ventilation is the single most effective way to prevent mold growth in a bathroom, and it protects the investment you are making in new tile and finishes.

Material selection should also account for the climate. Large-format porcelain tile holds up well in San Diego bathrooms because it has extremely low water absorption (less than 0.5%) and requires fewer grout joints. Natural stone like marble and travertine is beautiful but porous — it requires sealing at installation and periodic resealing to prevent staining and moisture absorption in a wet environment.

A straightforward bathroom remodel — same layout, no wall moves, standard scope — typically takes 3 to 4 weeks from demo day to final walkthrough. If you are changing the layout, moving plumbing, or waiting on custom glass or fabricated stone, the project extends to 5 to 6 weeks. We provide a detailed schedule before work starts so you know exactly when each phase is happening.

During a bathroom remodel, you will not have use of that bathroom for the duration of the project. If you are remodeling your only full bathroom, we plan the sequence to restore the toilet and a temporary shower connection as early as possible. Communication is constant — Christian provides updates directly and is available to answer questions throughout the project. There are no project managers or middlemen between you and the person running your job.
