Understanding a concrete pool and spa build
Yes, a spa can be formed and sprayed as part of the same concrete shell as your pool. Because the whole structure is custom, the spa can sit flush at one end, wrap a corner or rise above the waterline so it spills into the main pool.
Attached or spill-over spa design
An attached spa shares a wall with the pool and keeps the surface level, which suits a tidy, minimal yard. A raised spill-over spa adds a sheet of falling water as a built-in water feature. Think about where you will sit, the afternoon sun and the view back to the house.
Heating the spa and the pool
Warm spa water is usually the reason people add one, so decide early whether you want heating for the spa alone or for both bodies of water. That choice affects equipment, plumbing runs and running costs, and any separately licensed plumbing or electrical work needs licensed professionals.
Why fencing shapes the spa decision
An attached spa sits inside the same pool barrier, so plan the fence line around it. The barrier must be inspected and certified by the approving certifier before water reaches 300 mm, and a certifier-approved temporary barrier generally covers up to three months. The finished pool also needs QBCC registration, compliant gates and safety signage.
Spa pool quotes, licences and contracts
A spa adds structure, jets, heating and controls, so ask for each to be priced as its own line rather than one lump sum. Pool work over $3,300 needs a QBCC licensed contractor and a written contract, generally with a five-business-day cooling-off period, and the builder must arrange Queensland Home Warranty Scheme cover for insurable work above that amount.
Your next step on a pool and spa
Pick the spa position, attached or spill-over, and whether heating covers the spa only or the pool as well. Note your suburb and any extras such as salt water chlorination or water features.

What pool and spa combinations can cover
Attached spa
A spa sharing a wall with the pool at the same level, giving a clean, flat finish and easy step between the two.
Raised spill-over spa
A spa set above the pool so warm water flows over the edge, doubling as a water feature.
Heated spa only
Heating sized for the smaller spa volume, leaving the main pool at natural temperature.
Heated pool and spa
Heating planned for both bodies of water so the pool stays comfortable for longer each year.
