I love the cabinets and the benchtop. Looking good. I think the tiles in the top pic would look amazing but you really need to buy/borrow a couple and try them in situ.

What’s going on floor? In room and in hall.
The cabinets and bench are plain so what is your pop. The floor or the backsplash?
The inspire pic is a bit plain to my mind.
What will make you smile when you do your laundry. Yes hard ask I know.
Is this for u or to flip?
Do you have artwork for opposite wall or will that be plain?
So many questions.
Now I have new medium Grey laundry cabinets with laminate bench but it is behind glass sliding doors which along with an oak laminate vanity are the heroes. And I couldn’t justify cost of engineered stone. But I do question my decision now, but you have to rein in costs sometimes.

As kate said you haven't mentioned what is happening with the flooring, a light Oak could work

The green floor tile and the subway tile would look clean and fresh in your laundry , and keep the lightness that you have achieved with the cabinets and benchtop . As Bigreader said bring samples home with you to see in situ .

Done well so far. where’s the sink? Not in yet perhaps.

This is a kitchen but I like this shape too

Personally I absolutely love the herringbone tile effect. Very classy. Your benchtop is perfect, it looks fresh and clean, just as a laundry should! Go with what makes you happy!

It is a laundry . You spend an hour or less a day there . Visitors probably don't even see it . BUT why have white and white and white appliances and off-white tiles , when you can add some style , some personality , some colour , for maybe $1000 more ?

The good is that you are doubting the benchtop , and as it stands , so do I . But add ( as others have said ) oak floors , maybe do a couple of rows of white gloss 200 x 200 tiles BUT with a horizontal row of green or yellow or purple or whatever your favourite or appropriate colour is , subways around the top of the white ones .

Add brass or copper door handles , and you are done . Better than white eh ?

Actually , looking at the heights , you could probably only do 1 row of 200 x 200 tiles , and a row of subways , but it would give a lift and touch of class that would equal or surpass herringbone or terrazzo or similar wall tiles .

Or did you intend to tile the floor ?

It's a laundry and as such, you won't spend hours in it, so it needs to be practical without breaking the bank. Ditch the idea of herringbone tiles. Whilst it's lovely it will cost a lot more - as it's very time consuming and more wastage of tiles too.

White is very safe but it's boring and blah if you don't add some wow factor.

Daphnemaria has got it just right with her picture. Your laundry would benefit from a dark floor and splash back as this will anchor the room.

Then, to give that POP to the room, all you really need to do, is push the boat out and spend up large on some really funky, bright or unusual cupboard handles. Something that will make you smile. They could be bright yellow, red, one of each colour you like or some unusual shape.

To me grey tones makes the chore of laundry more depressing. In my laundry I have keep all white and added a sunny yellow door and a curtain of birds. Just brings joy to the task. And easy to change

If your leaving the floor as is..a light grey tile or marble effect would look classy. However, a dark tile with a darker flooring would also look good.

...From your pictures, the second image of the grey tile with black fittings in the pic and the second last image of the marble effect with black fittings in the pic would suit.

What is the rest of the house like? What do you have in the kitchen and bathroom? What is a colour you like?

I haven’t worked out how to link directly to other Houzz posts but these ones looks nicely finished and the colour comes from the shelves, plants etc.
