Choose a good contractor. We redid our kitchen 11 years ago and our bathrooms 5 years ago. If our kitchen contractor had done bathrooms, we would have stayed with them.
Write down all your wishes and things that bother you about the current kitchen.
I wanted to have my knives in a drawer, as I never liked having a knife block on the counter. In the same drawer I have dispensers for aluminum foil and plastic wrap. Really convenient.
I also have a spice drawer which has my most-used spices and herbs.
We have drawers for almost everything below the counter. Much easier to get to things in the back, including the food processor and mixer, and other small appliances which live underneath the counter.
Lighting: We have halogen lights underneath the cabinets and two fixtures on the ceiling. Each are controlled separately, so we can choose different lighting levels.
Outlets. Lots. Above the counter we have 5 outlets, one of which is by the light switches by the door. We have another outlet in the cubbyhole below the oven which is where we store dishwasher tablets, beverages and put the cans and bottles for recycling.
We have everything built-in, which is typical of where we live. This means that our fridge and dishwasher both have panels which match the cabinet fronts, so the overall kitchen appearance is much more harmonious.
We have an induction cooktop, a normal oven and a steam oven. Honestly, for most people the steam oven will not be used that much. We go through phases. We did not have, nor do we miss having, a microwave. And we’ve never had a toaster oven.
We have two countertops, as we have an L-shaped counter and a penninsula. The penninsula is plenty big enough for rolling out a pie crust and cooling dozens of cookies. We can put hot pans directly on the surface with no worries about damaging the finish. It is a big piece of engineered stone, so there are no grout lines on the horizontal surface, just on the corners agains the wall.
The L-shaped counter is stainless, and the sink is also stainless. The sink is part of the counter, and therefore there is no grout between the sink and the counter. We have one big bowl, and are happy with it.
Our kitchen renovation took three weeks. We put the fridge, espresso machine and a temporary hotplate (supplied by the contractor) on the back porch and had a few pieces of flatware and dishes. Each weekend we went away - once to Paris, where we visited some kitchen shops.
The contractor recommended to decide where to put hanging rails only after everything else was installed, as we could always add more later. We decided on one near the sink for towels and that was it.
We have a sliding door between the kitchen and the remainder of the house. We changed from solid wood to a milk glass door. Brings in more light.
