We've had our kitchen for 15 years & it's mostly still in brilliant condition, especially the wall & floor tiles, so it would really peeve me to even touch them tbh. I reckon we've got another 4 years life left in the cupboard doors before the laminate blisters. It's quite a small kitchen & it drives my dh mad. When the time comes he wants the kitchen knocked through into my study to make it bigger & more open plan, & part of my study made into a utility room. I don't really need my study now, like i used to but it comes in useful for the bookshelf & desk/laptop for household admin.
He wants to do it to give us more space & it'll be a better sell for our adult dc, should they be lucky enough to inherit the house.
Thing is, we've managed like this for 25 years. It's a nice kitchen but small. All this renovation should have been done years ago when we still had dc at home. When we come to have the kitchen replaced we'll be early 60's & on our own.
Without meaning to sound morbid we'll have more years behind us than in front of us. Considering how good a condition our current kitchen is in after 15 years how many more years enjoyment, or really caring about the size of it will we have left when we're in early 60's.
In our situation would you go through all that expense, mess & upheaval for just a relatively few years left of enjoyment of it, or have a new kitchen when the time comes & manage with the space/layout as we always have. It's a while off yet, but we're saving for it. I feel I will want an amazing holiday instead of having walls knocked about in the future.
