Replace with polished concrete! Will only be a thin layer, though, so may not work unless you take it down pretty far.

I would leave it but polish off that shiny varnish - you need to distract the eyes from the floor - when you update the kitchen it won't be so obvious. Make the lower cupboards a darker colour - not white. You should make all the other features simple & streamlined - the cupboard doors above just make it seem so busy - too much going on.

I love slate floors, but I think you have to embrace the feeling they create and team with other natural surfaces like wood. There was some good design in the 70's and you could go with that vibe and run with it.

At the moment it is looking quite drab, a vibrant splash of orange would lift the mood of the room. I'd suggest buying some coloured paper or card and blu tacking it to the tiles to see how colour affects the room and whether that's something you like.

I've seen an American house on houzz that modernised a 70's house while staying true to the design features of the time and it looked fab. But it might not be your thing....

Personally I like the floors. I would consider replacing the backsplash though. It would also help to install glass inserts with a design glass feature on the upper cabinets. A big change that isn't too costly. Congratulations on your new home.

It would be much more cost effective to work with the slate. Image sent by mazgardiner looks great. If the home was purchased for rental purposes, the plinth could be painted white, benchtop and splashback tiles painted (much cheaper than replacing) to blend in with slate colours. If you are going to live in the property, sometimes it's best to live with how it is and replace later when you have better understanding of what you want. Good luck with it all!

I just ripped mine out and replaced with porcelain. Much easier to clean and makes the area look larger, brighter and more inviting.

I agree with pascoeyvonne's idea and as suggested live with it till U work out a plan of action, but collect all the advise as well.

What is underneath it? We ripped our slate up recently (cold, hard and hadn't been sealed properly!). If you have floorboards underneath (like we had), then you just need to sand and coat them. So is quite an affordable option, especially if you do yourself.

You can coat them with a matt finish like floor boards they don't have to shine, although it looks cleaner

Are you replacing the cabinets as they and the splash back don't go with the floor, so does it mean keep floor or cabinets? This of a lovely Foodie in her kitchen, loving the green subway tiles, they would look good in your kitchen with the current floor.

I love slate - never had it in a kitchen as I'd worry about hardness and dropping things - but always found it both beautiful and easy to look after. I'd be inclined to simplify the rest of the kitchen to go with it, and yes, less shiny finish, but slate is a classic and looks expensive when done well. Yours looks good to me, but spashbacks and colour of cupboards could change (cheaply).
