LONG BEACH SPA BUILDERS
Custom Spa Construction Throughout Long Beach
A custom in-ground spa is one of the highest-impact things you can add to a Long Beach backyard. It works year-round (the marine layer is no match for a properly heated spa), it adds real resale value in coastal markets like Naples and Belmont Shore, and it pairs beautifully with a remodel or new pool build.
Werth Builders has been building gunite spas in Long Beach since 1994. Spillover, standalone, attached, raised, infinity edge — whatever fits the yard, the budget, and the look you are after.
- 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 Long Beach permits handled in-house
- Marine-grade equipment specs available for coastal lots
SPA OPTIONS
Custom Spa Configurations We Build
Every Long 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 Long 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 Long Beach
Building a custom spa here means understanding this city specifically — climate, soils, permitting, and the way Long Beach homeowners actually use their backyards.
Naples Island Spa Retrofits
Adding a spa to an existing Naples Island pool means working around shallow groundwater, marine-grade equipment specs, and Coastal Development Permits. We have retrofit spas onto Naples canal-side pools without disturbing the bulkhead or breaking neighbor walls.
Belmont Shore Compact Builds
Belmont Shore lots are tight, but a 6×6 or 7×8 spa fits in nearly any backyard. We design vertical, low-footprint installations with raised walls, tile facings, and sound-tuned equipment so a spa in a 30-foot-wide lot doesn't broadcast pump noise to the neighbors.
Marine-Grade Heater Specs
Long Beach marine layer destroys generic gas heaters in coastal neighborhoods. We spec stainless heat exchangers, sealed pad installations, and anti-corrosive supply lines so your spa heater lasts the full design life — even within a few hundred feet of the bay.
Bixby Knolls & Inland Backyards
Inland Long Beach yards have room for larger standalone spas, fire-bowl edges, and integrated decking. We have built classic 8×8 raised spas and modern 10×10 spa-pools in Bixby Knolls, Los Altos, Park Estates, and California Heights — paired with travertine, paver, or board-formed concrete decks.

SPA BUILDER FAQs
Common Questions About Building a Spa in Long Beach
A standalone custom gunite spa in Long Beach typically runs $25,000 to $50,000, depending on size, raised walls, tile selection, equipment, and finish. Adding a spillover spa to an existing pool is usually $20,000 to $40,000. Coastal Zone properties run a little higher because of marine-grade equipment and any required CDP.
A standalone custom spa takes 4-8 weeks from excavation to first soak. A spillover retrofit on an existing pool runs 5-10 weeks because we time the spa shotcrete with a partial pool drain and finish work. Coastal Development Permit review can add two-to-four weeks before we break ground.
A prefab spa is faster and cheaper up front (typically $8,000-$20,000 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 the life of the home, and adds real property value in markets like Naples and Belmont Shore. For most Long Beach homeowners, custom is the right answer.
Yes. Any spa over 24 inches deep, or any spa with electrical, plumbing, or gas, requires a Long Beach Building & Safety permit. In the Coastal Zone (Belmont Shore, Naples, Belmont Heights, Alamitos Peninsula) a Coastal Development Permit may also be required. Effective January 2026, all new projects must include at least two of seven approved drowning prevention safety features per California HSC §115922.
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. Naples Island canal pools and Belmont Shore tight-lot pools both make good spa retrofit candidates.
Massively more efficient than 10-year-old equipment. Modern variable-speed pumps, low-NOx heaters, and smart automation can heat a Long Beach spa to 102°F in 30-45 minutes from cold and hold temperature for almost no money on a properly insulated cover. Most homeowners see equipment payback within 2-3 years on the energy savings alone.
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.
