The base

Check the building requirements that vary widely depending on local law before you actually start your project. Footings and a concrete base are generally the first steps when preparing the area. If the tub is recessed in the ground, excavate the area and smooth out the ground surface, ensuring that it is level and free of unnecessary debris.

The hot tub can weigh up to 2 tonnes when filled with water, so the supporting structure must be really solid and level. Do not hang the tub on the edges as there will be not enough support.

If the hot tub is recessed down into the deck, make sure you plan for adequate access to the hot tub. Especially if you decided to go for a massage system, LED lights, filtration or electrically heated hot tub, access to them should not be restricted as maintenance and some service might be needed.

Supporting structure of a hot tub

If you opt for an electric heater, then additional wooden boards are needed. Therefore a wooden cross is also added under the tub. Please see the picture below to get a better idea of how it looks like. It will not be visible when you recess the tub, but the supportive boards will keep the electric heater stable and in place. Massage systems do not require anything extra and can be installed/mounted on the tub as it is.

Hot Tub

The drain

Terrace hot tubs can be equipped either with an external water tap or a siphon. The latter drain is similar to a water outlet in a bathtub, is also great for collecting all of the water. Installed in the floor of a terrace model, this water outlet can be opened by simply removing the plug. The other end of the siphon is a flexible hose/elbow of 46mm. This end goes under the hot tub. Make sure that the flexible hose (75cm length) is not crushed between the foundation and the hot tub base. Either the hot tub should be raised a bit to provide space for the flexible hose, or, in case the hot tub is set straight on the ground, a narrow groove, about 15cm deep, is dug in the ground to fit the flexible hose. The siphon can be installed in any part of the floor, though not in the middle if you opted for an electric heater, as the support structure is then made differently, and a wooden cross is just in the center. Also, in a model with conical walls and internal heater, there is a spot under the heater where the siphon can be installed without bothering you as it is hardly visible there.

The external water tap is a stainless steel pipe equipped with a ball valve for hassle-free opening and closing. The standard 32mm diameter (1 inch) ensures that connecting parts if you decide to connect the outlet to a hose or a pipeline, are readily available. To empty the hot tub, simply open the valve. The external water tap is L-shaped and installed in the floor of a sunken hot tub, so it will collect every bit of water as well as the syphon. The valve sticks out from the side of the hot tub. The place can also be chosen the same as with the syphon and not in the middle, if the wooden cross is needed.

Transportation

Most of the time, the hot tub is delivered standing on its bottom due to its shape, in some cases, it can be put on the side and packed on the pallet*. As these tubs weigh around 100-150kg, usually unloading is done without any additional equipment. The hot tub can be carried in its horizontal

position by a group of people. You can grip on the edge and carry it to its final position. Remember that the hot tub is heavier on the oven side if it is designed for the internal oven.

  • Classic models with straight walls can be packed on a side or any model with the electric heater as there are additional boards.
  • Please inform us if the pallet is needed for unloading with forklift

Installation

The process of the installation may vary whether the hot tub is installed in an already existing terrace or a new terrace is built for the installation. The diameter of the circle in the terrace should be either 1960 mm or 2020 mm depending on the model size i.e. the exterior diameter of 2010 mm or 2080 mm. Use a jigsaw to cut the circle, carefully lower the hot tub through the cutout in the terrace. Be especially careful not to damage the drain. Ensure that the hot tub does not hang on the edges. Once the hot tub is positioned, you may connect the accessories to electric supply, make sure you have an adequate access to the plugs and buttons.

Electric heater requires less maintenance while heating the outdoor hot tub because there is no need to add wood to the oven, control the fire and to clean it after using the tub. We offer electric heaters from 3 to 18 kW, it can be adjusted to single phase power (3 and 6 kW) or three-phase power (more than 6 kW). However, due to the differences among countries laws, one should consider consulting a local electrician. An electric heater is a perfect option if there is a lack of wood in your area. There is no chimney, no smoke, no need to clean the oven afterward. In general the heating process is shorter compared to the wood-fired oven, however, these tubs completely depend on the electricity and must be close to the connections.
