Gunite Spa Design
Closing the Comfort Gap in Spas - Aqua Magazine gives a good overview of what is possible.
If you want a good number of spa jets and high water pressure from the jets then a dedicated spa jet pump that is not going through the restrictions of the filter and heater plus the proper large size pipes is needed to get the necessary GPM flow.
For example, with 8 jets you want to be able to flow 120 GPM. That requires at least 3" suction and 2.5" return to spa jets although I would do 3" to spa jets.
| Pipe Size | 6 ft/sec | 8 ft/sec |
|---|---|---|
| 1.5" | 38 GPM | 51 GPM |
| 2" | 63 GPM | 84 GPM |
| 2.5 | 90 GPM | 119 GPM |
| 3.0" | 138 GPM | 184 GPM |
Spa Seat Design
Its not uncommon to have angled back rests, foot supports and rolled bond beams. There really is no limit to what is possible.[1]
Attached spas are 100% customizable. A spa was built for a very picky lady. She put on a tyvek suit and lay in the wet plaster in the spa so it was contoured to her body.
The bottom line is you can get whatever you ask and are willing to pay for.
Spa Coping
Consider doing a rolled tile edge on the spa instead of the traditional overhang coping.[2]
Spa Jets
Paramount ParaJets massage therapy spa jets allows the ability to change or move the therapy jet faceplates to different stations in your spa with a simple twist. ParaJets offer 4 interchangeable massage therapy jet faceplates; Deep Tissue, Shiatsu, Pulsating or Soft Stream.
Spa Air Bubbles
Some spas get air bubbles into the jets through a venturi system pulling air through an open pipe. Other spas use a powered Spa Air Blower for bubbles through the jets.
The Paramount Air- Port is a muffled air intake that can be installed in the deck near the spa. The Air-Port eliminates the need to run extended air intake lines and thereby eliminates the problems associated with flooded lines.
Spa Spillway
A gunite spa usually has a spillway for water to flow into the pool.
The negative wall design of the spillway pictured below keeps the tile in the spillway under water when the pump is off or spa spillover not running and the tile is not exposed to air and evaporation.[3]
The picture is looking from the spa to the pool. Take note at the bottom of the tile line as it has deeper water at the spa than at the ending point spillway to the pool.
