Spa Builders Irvine, CA — Compact Spillover & Standalone Spas
Irvine's newer villages were built with backyards too small for a full pool but plenty of room for a custom spa. We design 6x6 and 8x8 spillover and standalone gunite spas for Stonegate, Cypress, Eastwood, Portola Springs, and Five Point — engineered for tight setbacks, zero-lot-line constraints, and HOA review.

IRVINE SPA BUILDERS
Custom Spa Construction Across Irvine
A custom in-ground spa is one of the highest-value additions for an Irvine backyard, particularly in the newer villages where lots are tighter. Stonegate, Cypress Village, Eastwood, Portola Springs, and the Five Point Great Park neighborhoods routinely have 600-1,500 sf usable rear yards with zero-lot-line side setbacks — the perfect footprint for an 8x8 raised spa with a tile wall, sound-tuned equipment, and integrated decking.
Werth Builders has been building Irvine spas since 1994. From compact stand-alones in Stonegate to spillover spas attached to remodeled pools in Woodbridge and Northwood, to estate-scale spillover features in Shady Canyon and Hidden Canyon — we design to the lot, the HOA, and the way the spa actually gets used.
- 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 Irvine permits handled in-house
- Marine-grade equipment specs available for coastal lots
SPA OPTIONS
Custom Spa Configurations We Build
Every Irvine 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 Irvine 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 Irvine
Building a custom spa here means understanding this city specifically — climate, soils, permitting, and the way Irvine homeowners actually use their backyards.
New-Village Compact Spas
Stonegate, Cypress Village, Eastwood, Portola Springs, Beacon Park, Pavilion Park, Rise, Solis Park, Cadence Park — all built with tight motor-court lots where a full pool will not fit. A 7x7 or 8x8 raised spa with a sheer descent into a small wet deck, or a stand-alone spa with bench seating, fits ARC profiles and the lot reality.
HOA-Ready Submittals
Every Irvine ARC has its own equipment-screening, height, color, and material rules. We prepare submittals matched to each village's palette — Mediterranean stucco for Westpark, Spanish for Cypress, contemporary for Eastwood, Tuscan for Orchard Hills.
Sound-Tuned Equipment Pads
Most Irvine ARCs and most neighbors care about pump and heater noise. We sound-isolate equipment pads, spec variable-speed pumps that run at low decibels, and locate equipment to minimize neighbor objections — particularly important in zero-lot-line villages.
Spillover Retrofits for Older Villages
Many original Woodbridge, Northwood, University Park, and Westpark pools never had a spa. We retrofit attached or spillover spas as part of a wider remodel — tying into existing pool plumbing or adding dedicated spa equipment. Typical 5-9 week timeline.
OUR PROCESS
From First Call to First Soak
Five clear steps — same process whether you are adding a spa to a new pool, retrofitting an existing one, or building a standalone.
Free On-Site Consultation
We come to your Irvine home, walk the yard, talk through how you actually want to use the spa, and give honest feedback on what fits.
Design & Selections
3-D rendering for full new builds. For retrofits, we bring tile, finish, and coping samples to your home so you can see them in your own light.
Itemized Quote & Permits
Fixed line-item pricing. We pull every City of Irvine permit and any Coastal Development Permit the property requires.
Construction
Excavation, steel, plumbing, gunite, tile, plaster, equipment. Daily on-site supervision. Most spa projects run 4-8 weeks.
Fill, Heat & Walk-Through
We fill the spa, balance the chemistry, run the heater up, and walk you through equipment, automation, and care.
SPA BUILDER FAQs
Common Questions About Building a Spa in Irvine
A standalone custom gunite spa in Irvine typically runs $25,000 to $50,000, depending on size, raised walls, tile, equipment, and finish. Adding a spillover spa to an existing pool is usually $22,000 to $42,000. Shady Canyon and Hidden Canyon estate-scale spas with all-tile interiors and full automation can run higher.
A standalone custom spa takes 5-8 weeks from excavation to first soak, plus 2-4 weeks for HOA review. A spillover retrofit on an existing pool runs 6-10 weeks because we time the spa shotcrete with a partial pool drain.
Yes, in nearly every village — provided the design respects setbacks, height limits, equipment-screening rules, and the village's color/material palette. We prepare HOA submittals as part of our standard scope. Strictest reviews are in Shady Canyon, Hidden Canyon, and Orchard Hills Groves.
Most Irvine ARCs prefer (or sometimes require) built-in gunite spas matched to home architecture over portable acrylic spas dropped onto a pad. Gunite spas last 30+ years, integrate with the home's aesthetic, and add real property value. For permanent Irvine installations, custom is usually the right answer.
Yes. Any spa over 24 inches deep, or any spa with electrical, plumbing, or gas, requires a City of Irvine permit. Per California HSC §115922, all new spas require at least 2 of 7 approved drowning-prevention safety features.
