Prerequisites for installing a whirlpool bath

Preliminary checks

Before installing your whirlpool bath , make sure you have enough space.

Also, check the strength of the floor : once filled, the water and equipment can exceed 300 kg . A fragile floor can then compromise safety.

Also ensure the presence and accessibility of hot and cold water inlets for easy connection.

Electrical standards and regulations

The electrical installation of a whirlpool bath must comply with the NF C 15-100 standard , guaranteeing safety and compliance . Your bath must be connected to a 30 mA differential circuit breaker , with mandatory earthing and equipotential bonding to avoid any electrical risk.

The connection must be made via a dedicated circuit , without an intermediate socket or extension cord.

Pay attention to safety dimensions : the bathtub and its electrical components must be installed at a minimum distance from other equipment. A certified electrician can check your installation and ensure it complies with current regulations.

The steps for installing your whirlpool bath

Preparing the space

Before installing your whirlpool tub , carefully prepare the space . Start by thoroughly cleaning the area. Then, apply a water-repellent treatment to the walls and floor to prevent moisture and water infiltration.

Next, level the surface : a poorly aligned bathtub can cause leaks and poor drainage . Check the balance with a spirit level. A stable, level base ensures optimal operation and will extend the life of your equipment.

Installing the bathtub

The installation of the whirlpool bath must be carried out with precision to ensure stability and watertightness . Start by positioning the bath in its final location, ensuring that it is perfectly level using a spirit level. If necessary, adjust the adjustable feet to leave a minimum gap of one centimeter with the floor.

Also check that the water outlet is properly aligned with the siphon and adjust if necessary.

Plumbing connection

Connecting the plumbing is a key step in ensuring the proper functioning of your whirlpool bath . Start by installing the hot and cold water supply hoses , connecting them to the mixer tap . Make sure to tighten the fittings securely to avoid any leaks . Next, connect the drainage system , connecting the siphon and plug to the existing drain. Check that the slope is sufficient for optimal drainage . Finish by testing by filling the bath, then emptying it to detect any leaks . Whirlpool bath installation - Plumbing connection

Secure electrical connection

The electrical connection of a whirlpool bath must comply with strict standards to guarantee your safety . Start by connecting the bath to a dedicated circuit protected by a 30 mA differential circuit breaker , directly connected to the electrical panel .

Then check the ground connection and make sure all connections are tight to avoid any electrical hazard.

Once the electricity is connected, perform a power test . Turn on the pump, check the operation of the hydromassage jets , and make sure all components are responding correctly. If in doubt, call a professional electrician .

Adjustments and finishes

Adjustments and finishing touches ensure the stability and watertightness of your whirlpool bath . Start with a final alignment check with a spirit level, then secure the bath permanently by tightening the adjustable feet.

Then install the apron and apply a silicone seal around the bathtub to prevent water infiltration. To finish, carry out an initial operational test : fill the bathtub, activate the hydromassage system, check the drain and make sure that no leaks appear.

Proper adjustment extends the life of your installation.

Two common mistakes to avoid

Bad alignment

Installing a whirlpool bath requires care and precision to avoid costly mistakes . Poor alignment, for example, can cause instability , affecting water flow and potentially causing leaks . Always check that the bath is level before permanently installing it.

Incorrect electrical connection

On the electrical side, an incorrect connection can represent a danger of electrocution . It is imperative to use a 30 mA differential circuit breaker , to respect the earthing and to ensure the connections are watertight .

Never plug the bathtub into a standard outlet! If in doubt, call a professional to ensure proper and safe installation .

Who can install your whirlpool bath?

Installing a whirlpool bath requires plumbing and electrical skills. Given this, you have several options.

A heating plumber can take care of connecting the water inlets, the drains and the seals , while a certified electrician will ensure a secure connection with a differential circuit breaker and proper earthing .
