What should the installation surface for the whirlpool tub look like?
General guidelines: Choose a robust, even surface for the foundation of the whirlpool tub. If the installation surface moves or sinks into the ground, this can cause tension in the tub. The foundation under the whirlpool tub must be capable of bearing the weight of the whirlpool tub, the whirlpool water and the users. A whirlpool tub can have a maximum filling weight of up to 2,722 kg. In addition, the weight of the whirlpool tub users must also be taken into account. If the foundation of your whirlpool tub is only slightly inclined, then this does not impair the whirlpool tubs's performance or its construction. The installation surface, however, should not have a slope, depression or bumps. Most terraces or backyards are built so that they slope away from the house, so water can flow away from the house. The inclination should not exceed 1.27 cm over a distance of 2.44 m. We recommend using a concrete base, concrete slabs or bricks, gravel, broken stones (3.81cm or less) or a reinforced board as ground material. In addition, your authorised Villeroy & Boch specialist dealer should be able to supply or recommend prefabricated whirlpool tub foundations.
NOTE: Concrete foundations should be at least 10.16 cm thick and be reinforced with reinforcing bars or reinforcing steel mesh. These bars or the mesh should be earthed by connecting them to an earth connection.
WARNING: The whirlpool tub foundation must lie on flat, stable and even ground in order to prevent serious damage to the whirlpool tub. Villeroy & Boch recommends consulting a qualified building contractor before installing the whirlpool tub foundation. If you require additional support, please contact your authorised Villeroy & Boch specialist dealer, who will gladly help you.
WARNING: The whirlpool tub foundation has to permanently carry the entire base of the whirlpool tub so no levelling pieces or shims should be used. If you have to level the whirlpool tub, then make sure the entire construction is fully supported both in the middle and at the edges. The levelling work must not create any cavities under the whirlpool tub. Before carrying out any levelling work, please contact your authorised Villeroy & Boch specialist dealer. Damage to the whirlpool tub due to incorrect installation, laying an insufficient foundation or incorrect levelling will void the warranty on the whirlpool tub.
CAUTION: You should consult a qualified construction engineer or building contractor before installing the whirlpool tub on a raised platform or a pedestal.
Installation on a raised platform: Make sure the platform can carry the maximum filling weight of the whirlpool tub as well as the total weight of the whirlpool tub users. In order to do so, you must know the carrying capacity of the platform and ensure that it is higher than the maximum filling weight of the whirlpool tub plus the total weight of the whirlpool tub users, otherwise serious injuries or damage to the construction can occur. You will find the required carrying capacity and the maximum filling weight of the whirlpool tub in the table with the technical data of your whirlpool tub. Otherwise, you are welcome to contact your authorised Villeroy & Boch specialist dealer.
