Main bathroom (10 sqm) with open shower, any ideas?

If you compare some corner bathtubs there with the actual price with the Duo Classic, the surcharge for a corner bathtub does not necessarily have to be higher at your plumber

You won’t have any different luck with the 115cm internal length of your Kaldewei. For comparison: Our corner bathtub with a 150cm leg length has 127cm internal length, in which I can comfortably lie with my 180cm fully stretched legs.

Gladly

So I found some corner bathtubs with a leg length around 150cm and a floor length of, for example, 138cm (Galatea S202 corner bathtub SUN 150 x 150) or 131cm (corner bathtub Largo 150 x 150 cm (1032)) after a short search.

Almost all 175cm bathtubs have, as it feels, less than 120cm floor length.

You are already at Reuter, good.

There are definitely significant differences. I know the equity prices of various suppliers and the differences are enormous, and then again compared to Reuter. For example, the same one for our first bathtub on the list was a factor of 2 compared to Reuter with the first supplier and another factor of 2 with the second, so in comparison to Reuter a factor of 4. Every plumber then gets different percentages from their suppliers, which they partly or not at all pass on to the end customers.

Reuter is not an indicator at all, especially since their shipping costs are sometimes really exorbitant!

Did I express myself poorly? If the price listed at Reuter is, for example, €650, and the plumber charges €1600, then the other tub, which costs €509 at Reuter, does not necessarily have to be more than €1600 at the plumber.
