Raised or flush: where the spa sits
We build attached spas two ways, and the choice comes down to how you want the yard to look from the house. A raised spa sits above the pool behind a short wall, so it reads as its own feature and its water falls into the pool below. We clad that wall in tile or stone to match the coping.
A flush spa sits at pool level, split from the pool by a narrow wall just under the surface. From the back door you see one sheet of water.
| Raised spa | Flush spa | |
|---|---|---|
| Where it sits | Above the pool, behind a short wall | At pool level, split by a wall just under the surface |
| View from the house | Reads as its own feature | One sheet of water |
| Suits | Pools that run along a back fence | Smaller yards that keep the view open |
Spillover into the pool
Spillover means the spa shares its water with the pool. While the spa runs, the pump pushes water in and the extra pours over a lowered section of the wall. You hear it as a small waterfall, and the chemistry stays the same in both. We can make that lip a narrow notch or the full width of the spa, depending on the sound and look you want.
Jets and the air blower
Seats come first, then jets. We lay out the benches and the corner seat before the steel goes in, and we place each jet at back height for the person sitting there. An air blower can add bubbles through ports in the floor or the bench. Every jet line gets plumbed and pressure tested before the shell is shot, because concrete covers it for good.
Heating the spa
Spa and pool run on one pump and one filter, and valves on the equipment pad switch the flow between them. The spa holds far less water, so it warms up on its own much faster than the pool. Gas can bring a spa up to soaking temperature quickly, and the heater choice for both is covered on pool equipment installation.
The barrier plan includes the spa
We draw the spa into the same safety plan as the pool, so the barrier, alarm or cover is on the plans for both. The options for the final inspection under Florida Statute 515.27 are laid out in our pool safety barrier guide.
Spa and pool prices
The spa price covers the concrete spa built with the pool, the spillover, the jets and the heater connection. The pool itself is priced by its water surface, and the calculator for it is on cost of building a pool. Where the spa goes in relation to the sun shelf and the house is part of laying out the pool, shelf and spa.
| Job | What it includes | Price |
|---|---|---|
| Attached spa | Raised or flush concrete spa built with the pool, spillover, jets and its own heater connection. | $14,000 per spa |
| Concrete pool (gunite or shotcrete) | Design, signed plans and permits, excavation, steel, plumbing, shell, waterline tile, coping, standard pump and filter, white plaster finish and start-up. | $230 per sq ft of water surface |
Labor and materials included, in US dollars, October 2026. The pool is priced per square foot of water surface (length × width). Spa, sun shelf and equipment upgrades are added at a fixed price each. Design, signed plans and permits are included. Site surprises such as rock, high groundwater or tight access are priced after the visit, before we start.
Frequently asked questions
How much does adding a spa to a new pool cost?
An attached spa built with the pool is $14,000 per spa. That covers the spa shell with its spillover and jets, plus the heater connection. The heater itself is priced with the equipment.
Can a spa be added after the pool is built?
Yes, though it costs more later. We have to cut the deck, tie into plumbing that is already buried and match tile that has aged. Built at the same time, the spa shares the dig and the shell pour with the pool.
Does the spa go on the same permit as the pool?
We draw an attached spa on the same signed plans as the pool, in one pool and spa application. Its electrical and plumbing work rides on the sub-permits tied to that permit, and inspection lists such as Miramar's check pool and spa steel and piping together.
