Very good bathtub. I have had it for 5 months. In my parents' house, we had a similar one from a different brand at 1.65 meters, and its seat would slide inside the bathtub when it got wet.
In this specific one, I'm talking about the 1.50-meter version, the seat is designed in a way that you nestle into it and it pulls you backwards instead of inwards, so you don't have to worry about slipping inside.
I weigh around 110 kilograms, with most of the weight in my backside and legs, and yet I sit very comfortably without any issues.
The bathtub is of good quality, its bottom is thicker and reinforced with more polyester. Its sides are thinner with fewer layers of polyester.
The base of the bathtub is screwed and glued on, of course, if you purchase it as a set.
I chose it with the base and its apron so that in case of leakage from the valve, I wouldn't have to break tiles and deal with moisture and such. The only negative thing so far with the apron is that it makes a hollow sound when accidentally touched with the foot.
During installation, after it was leveled and glued to the wall with a special adhesive applied by the craftsman (my choice was to glue it instead of screwing it), low-expansion polyurethane foam was injected to reinforce the bottom and prevent cracking over time. Be careful if you use foam, make sure the bathtub is filled with water to prevent it from lifting.
The only fake thing in the whole purchase was the drainage valve of the bathtub, which was of poor quality and was replaced with one from Fiore, where you can immediately notice the difference in construction and operation of the lever that opens and closes the plug, although the cost is higher, at least it was worth it.
I am also including photos because generally, with just two photos that each website has, you can't make a choice since you don't have a clear image of how you sit in the bathtub and how it actually looks, as there is no sample available in any store for you to see up close.
