Salon and spa TI electrical in Marin runs $22-$38 per sq ft. Standard scope: per-station dedicated 20A circuits (typical salon has 6-15 styling stations, each with dedicated circuit), shampoo area electrical with GFCI protection, color processing area circuits, water heater electrical (often dedicated large-capacity heaters), HVAC for ventilation of chemical odors, reception and retail area electrical, spa-specific equipment for spas (steamers, hydrotherapy equipment, sauna power if applicable), break area and back-of-house electrical.
01What makes salon/spa electrical different.
High amperage per station: each styling station typically has multiple high-amperage tools running simultaneously (hair dryer 1500-2000W, curling iron 100-200W, sometimes additional equipment). NEC continuous-duty calculations push to 20A dedicated circuits per station to handle the load safely. 6-station salon has 6+ dedicated 20A circuits just for stations — meaningful circuit count and panel space requirement.
Water proximity drives GFCI everywhere: salon spaces have water sources throughout (shampoo bowls, color processing, sinks for spa services). Per NEC, GFCI protection required on outlets within 6 feet of any wet location. Practical implementation in salon: GFCI on every outlet in the open salon floor area. Increases circuit count and complexity vs offices where GFCI clusters in restrooms and break rooms only.
02Equipment scope specific to salons and spas.
Per-station electrical
Each styling station: dedicated 20A circuit with 2-3 outlets at counter level for stylist tool use. Mirror lighting (often integrated 4000-5000K LED for accurate color work). Sometimes USB charging integration. Station electrical scope $400-$800 per station including circuit work.
Water heater capacity
Salons consume more hot water than offices — frequent shampoo washes, hair color processing, sometimes spa services. Often requires larger water heater than building default. Dedicated electrical circuit for tank heater (240V high-amperage) or gas water heater with dedicated venting. Discuss with plumbing contractor during design.
Spa-specific equipment
Steamers, hydrotherapy tubs, electric saunas, manicure/pedicure stations with built-in lighting, infrared therapy equipment. Each has specific electrical requirements coordinated with spa equipment supplier. Spa scope adds 30-60% over basic salon electrical.
03Common Marin salon/spa configurations.
Boutique hair salon (under 1,500 sq ft, 6-8 stations): focused scope on station electrical, shampoo area, retail electrical. Total electrical $35,000-$55,000 typical. Most common Marin salon configuration. Full-service salon (1,500-3,000 sq ft, 8-15 stations): broader scope with color processing area, nail station electrical, larger water heating, potentially spa services. Total electrical $55,000-$95,000.
Day spa (2,000-5,000 sq ft, multiple service rooms): adds spa equipment electrical (steam rooms, treatment rooms, sauna), more sophisticated HVAC for chemical and steam ventilation, premium lighting design. Total electrical $80,000-$160,000. Spa-resort with significant equipment: $150,000-$300,000+. We've completed 15+ Marin salon/spa TIs including several boutique salons in Mill Valley and Sausalito and a larger day spa in San Rafael.
Common questions.
How much does salon electrical cost?
Marin 2026: $22-$38 per sq ft typical. For 2,000 sq ft full-service salon: $44,000-$76,000 electrical scope. Variance drivers: station count (each adds $400-$800), spa equipment scope, water heating capacity, retail area sophistication. Boutique salons under $50,000; larger spas with equipment $100,000+.
How many circuits per station?
Typical: one dedicated 20A circuit per station with 2-3 outlets. High-volume salons sometimes use two 20A circuits per station for backup capacity. For stations with additional equipment (built-in steamers, electric massage chairs, intensive equipment), additional circuits may be required. Standard is one dedicated circuit per station; some practices use shared circuits for adjacent stations but creates capacity constraints.
What about ventilation for chemicals?
Salon chemicals (hair color, permanent solutions, nail products) require effective HVAC ventilation. Our electrical scope includes wiring for HVAC ventilation equipment (specified by HVAC contractor); HVAC ducting and equipment is HVAC contractor scope. Coordination between us and HVAC contractor essential — salons with poor ventilation are uncomfortable and code-non-compliant in many cases.
Do you do spa-specific equipment like saunas?
Yes — electric saunas, steam rooms, hydrotherapy equipment, infrared therapy equipment all require specific electrical work. We coordinate with spa equipment supplier on specifications and complete the electrical install per their requirements. Some equipment requires high-amperage 240V circuits, GFCI protection beyond standard, or 3-phase power for larger commercial equipment.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
Are you licensed and insured?
Yes. California State License Board C-10 Electrical Contractor #989290, in good standing. Carry general liability insurance and workers' compensation insurance as required by California law. Bondable on projects requiring it. Happy to provide proof of insurance to clients or property managers on request. License lookup: cslb.ca.gov.
