Begin by finding a location to place the hot tub. Have a concrete base for the hot tub poured on the site.
Look over all of the pieces of the hot tub kit (Image 1). Lay out the treated lumber (Image 2). You will build the unit on an elevated platform (Image 3). During the assembly of the hot tub, it’s important to keep the wood dry. If it gets wet during construction, swelling will occur and it may not seal properly.
Before sliding the two base pieces together, drill a couple of outlet holes that will recirculate the water. Come out about 5" from the edge so the holes will be covered by the bench and make them 36" on center (Image 1). When using a hole saw, only cut halfway through on the front. Then, cut on the back so that you do not blow out the hole and splinter the edges (Image 2).
Install the suction fittings in the base. Apply a bead of silicone to the hull fitting (Image 1). Then, hand tighten it, so it is snug, but not over tightened (Image 2). Plumb the two suction fittings together. Connect them together with PVC pipe and PVC glue (Image 3).
