What Champlain outdoor spa size should I get?

Depending on the usage, a good rule of thumb to follow is to accommodate a few chairs and a patio table inside the structure. Our smallest spa (8’) will comfortably accommodate 2 adults. If you need more space, increase the size of your spa by 2’ to give extra room for 2 more adults. (i.e. 10’ spa holds 4 adults).


Level of Difficulty:

Though the Champlain spa building requires some carpentry skills, it’s a great DIY construction project. Our spa kits include easy-to-follow instructions, diagrams, and assembly videos that will help you through the process.

Below is a series of photos showing one of our Champlain building being assembled.

Our measurements (i.e. Nominal & Actual Building Size) are taken from the outside face of the upright columns. In the figure above it is represented in measurement “A”, it is portrayed in plan view in the “Floor Framing” section further down on this page.

Wall Assembly

Spa wall assembly example

All our spa styles feature built-up columns comprised of upright posts sandwiched by wall sides on either side. The Champlain outdoor spa adds another element with the wall jamb that allows windows to be secured in the wall cavities. Below the windows are recessed cedar panels that form the solid knee wall, and above the window is a cascading system of pickets backed with glazing creating a transom around the top perimeter of the building’s walls.

If you have any other questions pertaining to the size of the building, please do not hesitate to ask us, we're here to help.

Roof Assembly

The Champlain roof increases in complexity as the size increases, below is the roof framing for the Champlain. For smaller sizes, the size and number of components incorporated in the roof structure are reduced.
