Custom Spa Construction Across Los Alamitos
Most original Los Alamitos pools never had a spa. Carrier Row, Plainview Homes, and Los Alamitos Park-era pools were built in an era when standalone spas were unusual. We retrofit attached or spillover spas as part of a wider remodel — common Los Al scope.
Werth Builders has been building Los Alamitos spas since 1994. Spillover, standalone, attached, raised — designed for the lot and the existing pool where applicable.

SPA OPTIONS
Custom Spa Configurations We Build
Every Los Alamitos 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 Los Alamitos 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 Los Alamitos
Building a custom spa here means understanding this city specifically — climate, soils, permitting, and the way Los Alamitos homeowners actually use their backyards.
Spa Retrofits for Mid-Century Pools
Most original 1950s-60s Los Alamitos pools lack a spa. Spillover and attached retrofits are one of our most common scopes here.
Compact Standalone Spas
On lots without pools, a 6x6 or 7x8 standalone gunite spa fits beautifully without sacrificing yard space.
Sound-Tuned for JFTB Overflight
We sound-tune equipment pads and pair spas with covered patios to manage the JFTB overflight reality of this neighborhood.
Engineered for Los Alamitos Soils
Los Alamitos alluvial soils need engineered shells, dewatering during excavation, and hydrostatic relief. We engineer for the conditions on your specific lot.
