I will be remodeling kitchen and replacing gas oven/range with induction cooktop (220V, 20 amp) + electric wall oven (also 240V, 30amp)
I don't know much about electricity and need help to determine whether my electric panel will support it.
Some other notes:
- I have ac/heat unit inside the apartment as well as water heater and both appear on the panel.
- I also have pictures without front cover but I can't seem to upload more than one picture. Please let me know if you prefer to see inside of the panel
- this panel is Siemens is G1224L1125(CU) and "Main Lug/Main Breaker Kit table on the panel label has the following:
100 AMP Main breaker
125 AMP Main breaker
100-125 Main Lug
Also, as per my comment below, I can remove jacuzzi and replace it with shower. Please let me know if that would help a lot or if I can accomplish what I need without removing it.

You can do this, but it will fill up your feeder!
Assuming that:
we can apply the multiunit feeder calculation methods from the Code (Art. 220 Part II) (albeit not the optional simplified calculations from Part III, as we are assuming a 90A feeder here which makes that method inapplicable) to your current configuration to get the following numbers:
For the lighting and receptacle loads, we get 11.4kVA which then gets a 35% demand factor for all load past the first 3kVA to yield 5940VA. From that, we then add the 4.5kVA water heater and the 3335VA A/C to yield a total feeder load of 13.78kVA, or 57A at 240VAC. This leaves just enough room for the 8kVA (or 33A @ 240VAC) range load from Column C of table 220.55, using note 4 to treat the cooktop and oven combination as a single range load of not over 12kVA nameplate.
The resulting breaker switcheroo -- if you feel uncomfortable with this, feel free to ask your friendly local electrician to do this for you
