Bathroom Remodeling in San Diego

Bathroom design balances spatial constraints, plumbing locations, code requirements, and aesthetic goals. Unlike kitchens, bathrooms are tightly governed by minimum fixture clearances and ventilation requirements that limit layout options.

California building code mandates minimum clearances between fixtures and walls. Toilets require 15 inches from centerline to side wall, 21-30 inches clear space in front. Showers must be minimum 30x30 inches interior dimension (36x36 is more comfortable). Doors cannot swing into required fixture clearance space. These requirements often limit layout options, especially in small bathrooms.

Mechanical ventilation is required in all bathrooms with showers or tubs. The fan must exhaust to exterior (not attic), be rated for bathroom use, and provide minimum air changes. We specify quiet (under 1.0 sones), energy-efficient fans that homeowners will actually use.

The shower/tub decision significantly impacts budget, space usage, and daily function. Each option has distinct advantages and installation requirements.

Custom tile showers offer unlimited design possibilities but require meticulous waterproofing. We build shower pans using either traditional mortar bed with topical membrane or modern foam pan systems with bonded waterproofing. Walls receive waterproof backer board (cement board or foam board) followed by liquid-applied or sheet membrane waterproofing that wraps corners and seams to create a continuous barrier.

The waterproofing layer is the most critical component—tile and grout are not waterproof. Water must be prevented from reaching framing and subfloor. We use Schluter, Wedi, or similar commercial-grade waterproofing systems with documented track records. This is not an area to cut costs. Proper waterproofing prevents mold, rot, and structural damage that costs tens of thousands to repair.

Tub selection depends on available space, budget, and bathing preferences. Alcove tubs (three walls) are most common in standard bathrooms, typically 60 inches long, affordable, and space-efficient. Freestanding tubs create striking visual statements but require more floor space, exposed plumbing, and floor-mounted or wall-mounted faucets. They sit away from walls on finished floors. Undermount tubs install beneath tile or stone decks for clean, integrated appearance. Drop-in tubs sit within framed platform. Both require waterproof deck construction.

Soaking tubs provide deeper water than standard tubs (typically 20+ inches vs. 14-16 inches). Jetted tubs include air or water jets for massage. They require dedicated electrical circuits, accessible service panels for pump access, and more complex cleaning maintenance. They've declined in popularity due to maintenance requirements and changing preferences.

Tile selection affects both aesthetics and performance. Bathroom tile must be rated for wet areas, slip-resistant on floors, and properly installed over waterproofed substrates.

Waterproofing is mandatory in shower areas and recommended behind all bathroom tile. We use commercial-grade systems from Schluter (Kerdi system), Wedi, Laticrete (Hydro Ban), or similar manufacturers. These systems include waterproof membranes, prefabricated corners, sealing tape for seams, and integrated drain assemblies. The entire shower becomes a waterproof envelope before tile installation.

Older homes often have inadequate waterproofing—just tar paper or nothing behind tile. This leads to mold, wood rot, and structural damage. Part of every bathroom remodel involves removing old materials and installing proper waterproofing systems that meet current codes and best practices.

Grout selection matters. Standard cement grout is porous and stains. We primarily use epoxy grout or urethane grout for shower areas—both are non-porous, stain-resistant, and don't require sealing. They cost more and require skilled installation but eliminate grout maintenance issues. For floor tile in dry areas, high-quality cement grout with proper sealing remains acceptable.

Grout width affects appearance and cleaning. Rectified tiles allow thin (1/8 inch) grout lines for minimal visual interruption. Handmade or irregular tiles need wider grout lines (1/4 inch or more) to accommodate size variation. Wider lines show grout color more, making it a design element.

Bathroom vanities combine functional storage with aesthetic impact. We fabricate custom vanities sized precisely for each space, using moisture-resistant construction and finishes designed for humid environments.

Bathroom vanities require special consideration for moisture exposure. We build boxes from plywood (not MDF or particleboard which swells when wet). All wood surfaces receive moisture-resistant finishes. Drawer boxes include ventilation holes to prevent moisture accumulation. Soft-close hardware is standard. Under-mount sinks provide clean countertop lines and easier cleaning than drop-in sinks.

Single vanities typically range from 24-48 inches wide. Double vanities need minimum 60 inches, with 72 inches providing more comfortable spacing. Floating (wall-mounted) vanities create modern aesthetic and easier floor cleaning but require solid blocking in walls during framing. Traditional floor-mounted vanities offer more storage and easier installation.

Fixture quality directly impacts daily experience and longevity. We specify fixtures from manufacturers known for quality construction, reliable performance, and available replacement parts.

Quality faucets feature solid brass bodies (not plastic), ceramic disc valves (not compression or cartridge which wear out), and durable finishes. Popular finishes include chrome (most durable and affordable), brushed nickel (warm tone, hides water spots), matte black (modern, shows water spots), and oil-rubbed bronze (traditional look, living finish that changes over time).

Shower valves should be pressure-balancing or thermostatic to prevent temperature shock when other fixtures are used. We install valves from Kohler, Moen, Delta, or similar manufacturers with lifetime warranties and readily available parts. Wall-mounted shower arms provide flexibility for rain heads or handheld units. Rough-in dimensions must be precise since tile surrounds valve—mistakes are expensive to correct.

Modern toilets use 1.28 gallons per flush (older models used 3.5-7 gallons). We specify dual-flush models that use even less water for liquid waste. Elongated bowls provide more comfort than round. Comfort-height toilets (17-19 inches vs. standard 15 inches) are easier for adults and elderly to use.

One-piece toilets have seamless design that's easier to clean but cost more than two-piece models. Wall-mounted toilets save floor space and simplify cleaning but require in-wall carrier systems installed during framing. Smart toilets with integrated bidets, heated seats, and automatic lids are increasingly popular for master bathrooms despite premium pricing.

Proper ventilation is mandatory for bathrooms with showers or tubs. California code requires exhaust fans that remove moisture and odors, protecting against mold growth and material degradation.

Bathroom lighting serves both functional and aesthetic purposes. Task lighting at mirrors is critical for grooming. Ambient lighting provides general illumination. Accent lighting adds atmosphere.

Best practice places lights on both sides of mirror at face height (60-66 inches from floor). This eliminates shadows under chin and provides even illumination. Single light above mirror creates shadows and is less flattering. Vertical sconces or linear LED strips work well. Light temperature matters—3000K provides warm, flattering light; 4000K is cooler and more clinical. Dimmable controls allow adjustment for different times of day.

Shower lights must be wet-location rated and properly sealed. Recessed LED trim kits designed for showers resist moisture and provide adequate illumination. General bathroom lighting can use recessed cans, flush-mount fixtures, or decorative chandeliers (in larger bathrooms). All bathroom lighting should be on GFCI-protected circuits for safety.

Bathroom floors must be water-resistant, slip-resistant, and durable. Popular options include porcelain or ceramic tile (most common, wide range of styles, waterproof), luxury vinyl plank (waterproof, softer underfoot, affordable, easier DIY installation), natural stone (elegant, requires sealing, can be slippery when wet), and heated floors (electric radiant mats under tile provide luxury comfort, especially on cold mornings).
