The depth of the interior is approximately 33cm.

Hello,
I just measured it:
Width: 48 cm
Height (with feet): 28 cm
and depth (front to back): 38 cm, here the interior of the microwave stands out at the square housing, at the back by 3 cm, roundish bulge (is included in the 38cm).

Greetings

Sharp PS254 sw (25 l):
Depth from inside is approx. 25cm, from outside - 40cm

I'm referring to the external depth of the appliance, not its capacity.
