ORANGE SPA BUILDERS
Custom Spa Construction Across Orange
Most original Orange pools never had a spa. Eichler tracts and 1960s-70s pool homes consistently lack the spa most homeowners now want. We retrofit attached or spillover spas as part of wider remodels — finishing to match each era. OPA estates support full standalone designs. Old Towne historic blocks need period-sympathetic spa detailing.
Werth Builders has been building Orange spas since 1994. Spillover, standalone, attached, raised, infinity-edge — designed for the lot, the era, and the way the spa actually gets used.

SPA OPTIONS
Custom Spa Configurations We Build
Every Orange 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 Orange 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 Orange
Building a custom spa here means understanding this city specifically — climate, soils, permitting, and the way Orange homeowners actually use their backyards.
Eichler-Compatible Spa Designs
Eichler architecture asks for clean rectilinear geometry. We design spillover spas with sharp tile lines, glass-tile interiors, and minimalist coping that match the post-and-beam vocabulary instead of fighting it.
OPA Estate-Scale Spas
Orange Park Acres 20,000+ sf lots support full standalone gunite spas with bench seating, raised stacked-stone walls, fire-bowl edges, and integrated decking. Some OPA homeowners use these as primary backyard centerpieces.
Old Towne Historic Retrofits
Old Towne spas need period-sympathetic detailing — terra cotta, brick, hand-troweled plaster, materials matched to the home's 1880s-1920s era.
Spa Retrofits for 1960s-70s Pools
Mabury Ranch, Riverbend, and original tract pools mostly never had spas. We retrofit attached or spillover spas as part of wider remodels.

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.

Common Questions About Building a Spa in Orange
A standalone custom gunite spa in Orange typically runs $22,000 to $48,000, depending on size, raised walls, tile, equipment, and finish. Spillover retrofits to existing pools usually $20,000-$42,000. OPA estate-scale spas with full features run higher.
A standalone spa takes 4-8 weeks from excavation to first soak. Spillover retrofits 5-9 weeks. Plus historic / hillside review where applicable.
For permanent installations and the architectural standards of Old Towne and OPA, custom gunite is almost always the right answer. Gunite lasts 30+ years, integrates with home architecture, and adds real property value.
For visible exterior installations, yes — Historic Preservation Design Standards review applies. We prepare submittals as part of our standard scope.
Yes — but the design needs to respect mid-century rectilinear vocabulary. We design rectilinear spillover spas with glass-tile waterlines and minimalist coping that fit Eichler architecture.
