Custom Spa & Hot Tub Installation in Fairfield County

Why Build a Custom Spa Instead of Installing a Showroom Hot Tub?

There is a fundamental difference between a portable hot tub sitting on a deck and a custom-built gunite spa designed as an integral part of your outdoor living environment. A portable hot tub is an appliance. A custom spa is architecture. It is built into the landscape, finished with the same materials as your pool and hardscape, plumbed into your filtration and automation systems, and designed to look like it has always been there.

At Gedney Pools, we design and build custom spas using the same gunite construction methods we use for our pools. Reinforced concrete shell, premium interior finishes, natural stone or tile exterior, dedicated heating, and full hydrotherapy jet systems. These are permanent, substantial structures that add both value and daily enjoyment to your property.

Whether you are building a new pool with an integrated spa, adding a spa to an existing pool as part of a renovation, or creating a standalone spa retreat separate from the pool, we handle every aspect of design, engineering, permitting, and construction.

What Spa Types Does Gedney Pools Build?

Spillover Spa (Attached to Pool). The most popular configuration in Fairfield County luxury homes. The spa sits at an elevated level adjacent to the pool, with water cascading over a shared wall into the main pool. This creates a stunning visual and auditory effect - the gentle sound of water falling from spa to pool adds an atmospheric quality that a standalone spa cannot match. Spillover spas share some plumbing with the pool but always have independent heating so you can heat the spa to 104 degrees without warming the entire pool.

Raised Spa with Waterfall Wall. Similar to a spillover spa but with a more dramatic presentation. The spa is raised 2-4 feet above pool level with a stone or tile-clad wall, and water falls in a wider sheet or multiple streams. This architectural element creates a focal point in the pool area and provides a visual screen between the pool and adjacent spaces.

Standalone Spa. A freestanding spa unconnected to the pool, positioned for views, privacy, or proximity to the house. Standalone spas are ideal for properties where the pool area is fully developed and there is no room for an attached spa, or where the homeowner wants a spa experience separate from the pool environment. These require their own complete mechanical system - pump, filter, heater, and controls.

In-Pool Spa (Wet Spa). A spa area built into the pool itself, typically at a shallower depth with perimeter bench seating and hydrotherapy jets. The water level is the same as the pool. While simpler to construct than a raised spillover spa, in-pool spas cannot maintain a separate temperature from the pool - a significant limitation for year-round spa use in Connecticut.

How Are Hydrotherapy and Jet Configurations Designed?

A spa without proper jet design is just a small hot pool. The therapeutic value - and the daily enjoyment - comes from the hydrotherapy system. We design jet configurations based on ergonomic seating positions, targeting specific muscle groups:

• Back jets: Positioned at various heights to target upper back, middle back, and lower back. Adjustable nozzles allow individual users to direct water pressure where they need it.
• Neck and shoulder jets: Positioned at seated shoulder height to relieve tension. These are typically smaller, higher-pressure jets with a rotating or pulsing action.
• Foot jets: Built into the footwell floor or opposite wall for reflexology-style hydrotherapy.
• Calf and hamstring jets: Positioned along the bench front to target the lower legs - especially valued by athletes and golfers.
• Air blowers: Produce a gentle, effervescent bubbling effect across the entire spa floor. Adjustable intensity creates a gentle shimmer or a vigorous boil.

We use multiple pump circuits so different jet zones can operate independently, and all jet systems are controllable through the pool automation system - adjust from your phone, set timers, or create custom hydrotherapy sequences.

Spa Features and Enhancements

• LED lighting: Color-changing underwater LED lights create atmosphere for evening spa use. We can synchronize spa lighting with pool lighting for a unified effect.
• Fire features: Fire bowls or linear fire features integrated into the spa surround create a dramatic contrast - fire and water - that defines luxury outdoor living. See our water and fire features.
• Automatic covers: Recessed automatic spa covers preserve heat, reduce evaporation, and provide safety when the spa is not in use. Essential for standalone spas.
• Aromatherapy systems: Integrated scent dispensers can infuse the spa air with eucalyptus, lavender, or other therapeutic aromatics.
• Premium finishes: Glass tile, hand-painted ceramic tile, pebble finishes in custom colors - the interior finish of your spa sets the visual tone for the entire experience.

Can You Use a Spa Year-Round in Connecticut?

Unlike pools, which have a seasonal window in Connecticut (typically May through September), a properly built spa is a year-round amenity. With a dedicated high-efficiency heater, insulated plumbing, and an automatic cover, your spa maintains temperature through the coldest Connecticut winters. There are few experiences more restorative than sitting in a 104-degree spa surrounded by a January snowfall on a clear night.

For year-round use, we recommend standalone or spillover spas with independent heating (not in-pool spas that share pool water temperature). We size heaters to handle the worst-case temperature differential - heating a spa from 40 degrees to 104 degrees on the coldest day of the year - so you never wait more than an hour for your spa to be ready.

Can You Add a Spa to an Existing Pool?

If you have an existing gunite pool and want to add a spa, renovation is the ideal time. We can:

• Build an elevated spillover spa attached to one end of the existing pool
• Construct a raised spa with a stone or tile feature wall
• Build a standalone spa in a separate area of the yard
• Modify the existing pool shell to create an integrated spa zone

Adding a spa during a pool renovation is more cost-effective than doing it as a standalone project because the pool is already drained, equipment is already being upgraded, and trades are already mobilized on-site.
