Do I need to reinforce the floor?

According to Hjältevadshus, the floor joists are designed for a standard bathtub. However, I have bought a jacuzzi that is quite wide, 120 cm. It weighs more than a "standard bathtub," whatever that means. The total weight is 100 kg and it holds 400 liters.

Do I need to reinforce under the bathtub for the floor to support the weight?

The floor is dimensioned to withstand at least 200 kg/sqm over the entire surface. How wide is the bath in the other direction?

Found the product sheet now. The dimensions are 1820x1220x660mm. Bath volume without bathers 240 liters, weight 110 kg.
Is it too heavy?

Does the 200kg/sqm apply to all floors on upper levels?

A correctly sized floor in a residential house should withstand 200kg/sqm. Additionally, there is a norm for how much point load the floor should withstand, but I don't know it. But presumably something like 1 or more tons on a small area. In public spaces, it has to withstand much more.

Your bathtub sounds relatively standard, in terms of volume. So it should be fine.

With that bathtub, the load is 157kg per sqm, and with a bather weighing 100 kg, it becomes 202kg per sqm.
So you don't need to reinforce anything.

Sounds good! Thank you for the answers.
