18ft x 8ft (internal) SWIM SPA PLANS STRUCTURAL / ARCHITECTURAL / PERMIT SUBMISSION

This is a swim spa which comprises of a Swim Jet as well as a 15 Jet Spa/Hot Tub seating area.

Total external dimensions are 276″ x 112″ – this includes the space needed for the swim jet

This package will give you the Structural / Architectural / Permit Submission Plan that you may need to submit to your local authority or city to get permission for your ​swim spa build. This has been drawn up by a structural engineer and is an architectural drawing. This is also perfect if you plan to use a contractor that is used to working from architectural designs rather than 3D renders.

You may need to have a local structural engineer sign off / stamp these designs for your local authority. Some require sign off by a structural engineer that is licensed in a particular State in the USA. These are not stamped drawings. They are however compliant and it is much cheaper to do it this way than to have a structural engineer design the whole thing for you.

This package also includes the New 2024 Ultimate DIY Guide which incorporates the Ultimate Control Room Guide worth $99 each when sold separately!

If for any reason your local structural engineer requests changes to the Architectural/Structural Plan before they will stamp it, I will make the changes for you at no charge.

The design comprises of a rectangular swim spa constructed with cinder blocks, CMU, ICF or Concrete Forms. There is comfortably seating for 8-10 people and more.

There are two steps down into the tub, generous seating space and 15 Jets.

The diagram will give you all the dimensions you need to construct your own swim spa.

I also include the plumbing drawings to enable you to calculate exactly what materials you need.

Plumbing drawings include stand alone drawings as well as isolated views.

I include a full shopping list of all parts required as well as some tips & tricks using our own experience for putting together your DIY Swim Spa.

This is the ultimate package of knowledge to assist with your own build.

(Swim Jet is sold separately) A Swim Jet or Counter Current is a machine that generates a flow of water against which you swim. When you swim at the same pace as the counter current, you are able to swim for as long as you like (or if you swim as well as I don’t lol, more “as long as your can!”)

The swim jet or counter current gives you a means of swimming naturally in a much smaller space than an Olympic sized swimming pool. This is ideal when space is of a premium in our back yards.

Who is this Swim Jet for?

Whilst there are models on the market that cost 4-6x the price of this particular unit, they are very much for the pro swimmer. This swim jet is notfor the pro swimmer. This jet is good enough for a “fitness swimmer”, even a “good swimmer” but not a “professional swimmer” in training.

It is possible to adjust the flow and the angle of the jet, but if you are an athlete in training or a professional swimmer, you are going to want to invest in a hydraulic-based system. They can increase the flow of the current considerably more and are suited to the speed an athlete in training needs to swim. This is an electric or jet pump-based system which is ideal for you and I to improve our fitness in ones backyard.

How Does the Swim Jet Work?

The counter current swim jet is a self-contained unit. The water is drawn in from the sides of the unit and then delivered back into the pool under pressure from the jet pump. There are clever designs inside the unit to minimise the amount of bubbles that are created.

From the front of the unit, there is an air switch that allows you to turn the unit on an off.

The air switch itself (well, the actuator) is connected to the physical electrical switch via tubing that when pressed, the air turn on the switch which in turn, triggers the pump to run. Pretty cool. Now it’s time to install a swim jet.

What are the Dimensions of the Swim jet?

Where do I position the Swim Jet in the Hot Tub or Pool.

Firstly, the pool or hot tub should be a minimum of 4m or 14′ in length. Otherwise, there can be a wave that comes off the back wall when you are swimming and can be off putting.

Secondly, the swim jet nozzle should be 250mm or 10″ below the surface. This is the same regardless of the type of construction method you are using on your pool or tub.
