depends on how you like to use the oven and size of your cooking equipment..i use my ovens every day and have big ovenware and the 60cm wide oven suits me... stacked ovens are easier to see into and we're very happy with stacked 60cm microwave over the 60cm oven above a saucepan drawer...how often will you use each appliance?...could you have a 60cm below counter oven with a stacked 45cm wide steam and/or microwave over drawers?

Sorry I should have been more specific. 45cm ovens are advertised as 45cm, but are actually 45cm tall, and are all 60cm wide. (I can't edit my post now).

This seems silly because 60cm ovens are 60x60, but 90cm ovens are 90 wide and 60 tall...

It seems they give you about 17cm between bottom tray and grill element.

We have our microwave hidden elsewhere.

2 ovens gives the chance to have 1 steam version. Not sure how useful steam ovens are...

Good point regarding electricity. We might end up with both on, and that would definitely be a waste of power.

I probably won't have space for 60+45 unfortunately. Appreciate your comments :)

always prefer stacked for ease of use both for viewing and lifting dishes in and out ... steam oven depends on how you like to cook...given the option i prefer to steam in a saucepan (for several thousand dollar savings) but we use the microwave constantly and stacked matching microwave over oven with cabinet and drawers above and below

This is our design so far. We have an additional peninsula with sink/dishwasher/microwave. That is a 60x60 oven pictured. I'm not sure I can give up additional oven room...we can't fit a butler's pantry into this house.

Yeah I'm a torn on the steam oven. It would be nice if it was the solution to cooking dumplings easily but I don't think it is.

2 ovens are better than one and can't really see the value in a steam oven when you can justt use the MW or a Wok with a bamboo steamer or a rice cooker with the steamer on top of the rice.

There’s no reason why you can’t have a 60 and 45 cm oven stacked, as in oklouise’s picture. You’ll loose 15cm in cupboard space compared to 2 x 45 cm ovens but I’d prefer the tra oven space.

You said your, not sure how good steam ovens are. I suggest you do your research on that question, before spending the money.
And I completely agree with all of genkii comments. 45 are too small, but a 60 and 45 may be just right. I have two 60, and work wonderfully when required. Cooking in one, while warming up in the other. Roast in one and desert in the other.

Put a pot draw under oven not cupboards. Cupboards only for pantry or tricky corner
Or a narrow cupboard for chopping boards and small appliances

Appreciate all the oven advice, thanks.

I think after reading all this I will just go for a 60x60 only.

Kate - we were originally using cupboards on the left hand side to save money, but might get a price for having drawers all the way along the entire wall (under bench height).
