NEWPORT BEACH SPA BUILDERS
Custom Spa Construction Across Newport Beach
A custom in-ground spa is one of the highest-impact additions to a Newport Beach backyard. It works year-round on the coast (the marine layer is no match for a properly heated spa). It adds real resale value in markets like Newport Coast, Pelican Hill, and Linda Isle. And it pairs beautifully with a remodel or new pool build for a fraction of the cost of a full pool.
Werth Builders has been building gunite spas in Newport Beach since 1994. Spillover, standalone, attached, raised, infinity-edge, perimeter-overflow — whatever fits the lot, the budget, and the architectural style of the home.
- Free on-site consultation with honest recommendations
- Spillover, standalone, raised, and attached configurations
- Tile, plaster, and equipment to match the existing pool
- All City of Newport Beach permits handled in-house
- Marine-grade equipment specs available for coastal lots
SPA OPTIONS
Custom Spa Configurations We Build
Every Newport Beach backyard is different. Here are the configurations we work with most.
Spillover Spa
The classic — spa raised above pool with sheeting water spilling over a tiled wall. Visually striking and functionally efficient (one heater serves both).
Standalone In-Ground Spa
Custom gunite spa, no pool needed. Built to your exact dimensions and finish — common for backyards that already have a pool, or yards that don't fit a full pool.
Attached Spa
Spa built into the same shell wall as the pool, sharing a tile cap. Cleanest look for modern architecture and infinity-edge designs.
Raised Spa with Tile Wall
Spa elevated above deck height with a finished stacked-stone, tile, or board-formed concrete wall. High-impact visual centerpiece.
Spa Retrofit
Adding a spa to an existing pool. We tie into existing plumbing or add dedicated equipment, match the new spa finish to a fresh pool resurface.
Equipment & Automation
Variable-speed pumps, low-NOx heaters, and smart controllers — including marine-grade specs when the property requires them.
CUSTOM vs PREFAB
Should I Build Custom or Buy a Prefab Spa?
Both work. Both have homeowners that swear by them. Here is the honest comparison so you can decide what fits your Newport Beach backyard.
Prefab / Portable Spa
Drop-in acrylic or rotomolded shell, 110V or 220V plug-in, no permitting in most cases. Lasts 10-15 years. Fastest path to soaking but lower resale value and cannot be customized.
$8K–$20K InstalledCustom Gunite Spa
Built into the ground, finished with the same tile and plaster as a pool, lasts 30+ years. Fully custom dimensions, depth, seating, and equipment. Adds property value.
$25K–$50KSpillover Spa (with new pool)
Best-in-class look and the most efficient option if you are already building a pool — shared equipment, shared finish, single permit application.
$15K–$30K (incremental)Spa Retrofit (existing pool)
Adding a spa to a pool that does not currently have one. Plumbing tie-ins, partial pool drain, structural and finish work. Mid-range cost, high-impact change.

Spa Building Tuned to Newport Beach
Building a custom spa here means understanding this city specifically — climate, soils, permitting, and the way Newport Beach homeowners actually use their backyards.
Newport Coast Hillside Spas
Hillside lots in Newport Coast, Pelican Hill, and Crystal Cove often suit a stand-alone or pool-attached spa with infinity-edge views over Catalina or the Pacific. We engineer caisson-supported spa shells, integrate with retaining walls, and design lighting that respects HOA dark-sky requirements.
Balboa Island & Peninsula Compact Spas
Where a full pool will not fit, a 6x6 or 7x8 spa often will. We design vertical, low-footprint installs with raised tile walls, sound-tuned equipment, and configurations that work on 35-by-85 Balboa Island lots and tight Peninsula yards.
HOA-Ready Submittals for Pelican Hill, Big Canyon, Linda Isle
Architectural review committees in the gated Newport Beach communities are detailed and specific — equipment screening, finish material, color, lighting, fence height. We prepare submittal packages that match each HOA's palette and submission requirements.
Marine-Grade Heater & Equipment Specs
Newport Beach marine layer destroys generic gas heaters and pumps. We spec stainless heat exchangers, sealed pad installations, anti-corrosive supply lines, and properly grounded electrical so your spa heater lasts the full design life — even within a few hundred feet of the bay or the shoreline.

SPA BUILDER FAQs
Common Questions About Building a Spa in Newport Beach
A standalone custom gunite spa in Newport Beach typically runs $30,000 to $65,000, depending on size, raised walls, tile selection, equipment, and finish. Adding a spillover spa to an existing pool is usually $25,000 to $50,000. Coastal-zone properties run a little higher because of marine-grade equipment and any required Coastal Development Permit.
A standalone custom spa takes 5-9 weeks from excavation to first soak. A spillover retrofit on an existing pool is 6-12 weeks because we time the spa shotcrete with a partial pool drain. CDP review (when triggered) adds 2-4 weeks. HOA review in Pelican Hill, Big Canyon, or Linda Isle adds another 2-6 weeks.
A prefab spa is faster and cheaper up front (typically $10,000-$25,000 installed), but you are limited to standard shapes, sizes, and tile colors, and resale value is lower. A custom gunite spa is built to your yard's exact dimensions, matches your pool finish, lasts 30+ years, and adds real property value in markets like Newport Coast or Linda Isle. For most Newport Beach homeowners, custom is the right answer.
Yes. Any spa over 24 inches deep, or any spa with electrical, plumbing, or gas, requires a City of Newport Beach permit. In the Coastal Zone (which covers most of the city), a Coastal Development Permit may also be required — particularly on first-row shoreline lots or in Bay Shores. Per California HSC §115922, all new pools/spas require at least two of seven approved drowning prevention safety features.
In most cases yes — even when the original pool was not designed for it. We tie new spa plumbing into existing equipment (or add dedicated spa equipment), match the new spa finish to a fresh pool resurface, and permit the structural work. Newport Heights, Big Canyon, and original Newport Coast pools are all great spa-retrofit candidates.
Yes. Werth Builders is a fully licensed California pool contractor (CSLB #777-575, B-1 General + C-53 Swimming Pool), bonded, and insured for general liability and workers' compensation. We have been building and remodeling in Southern California since 1994. Always verify any contractor's license at cslb.ca.gov before signing.
