Curbless showers, grab bars, comfort-height fixtures, and non-slip flooring — safe, beautiful bathrooms designed for aging-in-place or accessibility needs.
Accessible Bathroom Guide →A bathroom is a small room with a lot of decisions: waterproofing, drain locations, tile layout, lighting, ventilation, and 2026 code. Our in-house bathroom designers and builders plan all of it together, so nothing gets lost between the drawing and the job site.
Where plumbing can move and where it shouldn't, curbless shower entries, double-vanity clearances, and storage that fits how you use the room. For aging-in-place, see our accessible bathroom guide.
Large-format porcelain, zellige, natural stone slabs, and feature walls chosen for looks and for how they hold up to daily water. Our guide to the best bathroom tiles covers the trade-offs.
Slip resistance, radiant heat compatibility, and moisture performance matter more in a bathroom than anywhere else in the house. Compare options in our bathroom flooring guide.
Because the designer and the builder are one team, every design choice is priced as it's made. You see the real cost of a steam shower or a slab wall before you fall in love with it, not after.

As a licensed design-build contractor, Optimal handles architecture, design, permitting, and construction in-house. One point of accountability — from the first conversation to the final walkthrough.
CSLB License #1091450. Every project is fully permitted, inspected, and built to California code. You're protected at every stage.

One person accountable for your entire project — scheduling, subcontractors, inspections, and daily updates. You always know what's happening next.
After your free in-home consultation, you receive a detailed written proposal — scope, materials, timeline, and total cost. No vague estimates.
We've remodeled bathrooms in every San Diego neighborhood. We know local codes, DSD requirements, and the conditions that affect your project.

Cosmetic refresh. Existing layout retained. Visual transformation without structural changes.
Full transformation. All surfaces replaced, plumbing and electrical updated.

Master bathroom remodel · San Diego, CA · Optimal Home Remodeling & Design
We visit your home, assess the space, and listen to your goals. Within 48 hours you receive a detailed, itemized written proposal — scope, materials, timeline, and total cost. No vague estimates, no surprises.
Our in-house design team creates your plans, helps you select every material and finish, and handles all permitting with San Diego's Development Services Department (DSD). You approve every detail before demolition begins.
Your dedicated project manager coordinates every trade, communicates proactively, and keeps your project on schedule. We protect your home daily, clean up every evening, and don't call the job done until you do.
As of January 1, 2026, updated California Energy Code (Title 24) and CALGreen (Part 11) standards are in effect. Optimal handles every permit, inspection, and code requirement through San Diego's Development Services Department — you never deal with city bureaucracy directly.
All new toilets must meet EPA WaterSense certification, capped at 1.28 gallons per flush. Showerheads must not exceed 1.8 gallons per minute under the 2026 standards.
Bathroom lighting must be high-efficacy LED, controlled by a vacancy sensor (manual-on, auto-off). Standard switch-controlled lighting no longer meets 2026 compliance requirements.
2026 codes require moisture-sensing exhaust fans that activate automatically based on humidity — especially important for coastal San Diego properties in Pacific Beach and Oceanside.
Many bathroom remodels qualify for a Simple "No-Plan" Permit if no structural walls are moved. Full permits are required for layout changes, electrical upgrades, or plumbing relocation.
We are very pleased with the beautiful job that Optimal Home Remodeling and Design just completed in our primary bathroom. The workmanship, attention to detail, professionalism, and staying on the time schedule were all top notch. The included design assistance helped immeasurably in creating a beautiful bathroom space for us.
We did a complete master bathroom remodel in my father's home in La Jolla, converting a dated sunken tub/shower from the 1970s to a curbless shower that is ADA compliant. … Unlike other bids we got, Dotan's was a carefully detailed plan that listed everything that needed to be done, along with any possible contingency that could be expected.
No other contractor we spoke with could figure out a solution for the tub to fit, so I think this speaks highly to the level of skill and expertise that Dotan has. … I was also very happy with Tal, the designer, as she made beautiful aesthetic choices and was always willing to work within our budget.
Coastal bathrooms in Pacific Beach and Oceanside need serious moisture control; older homes in Point Loma and La Mesa often hide galvanized plumbing behind the tile. We plan for both. See local projects and details for your area:
