Can you post a photo?

Sorry, I don't know why the photo wasn't there... it seems fine now.

Change the mirror and lighting and wall additions.

I would try to play up the total Liberace Kitschiness of it rather than fight it. It is what it is and it's kind of fun if you turn your thinking around.

But lose the pink paint and get better mirror and lights. Those bulbs were in my bathroom built in 1965 and they don't even go with the baroque feeling of all that marble overload :-)

I would pick a cream paint and remove all the wierd stuff hanging from the walls. New mirror and lighting. The floor looks like carpet - I hope I am wrong on that.

Is this north America? I have never seen a marbelized toilet (carved out of marble, yes, but not like that).

If you wanted to, a white pedestal sink and toilet aren't that expensive.

I would try to sell the toilet and sink, they are interesting enough that someone might like them.

I think the right off-white paint color covering the pink would help a lot.

I agree with the others about removing the various unusual wall-mounts and change out the sink, toilet, light fixture and mirror. I believe the outside of the tub could be painted a solid color to match the sink and toilet -- I would do them all in white. Then paint the walls a nice cream/beige color, and you would have a nice neutral beige/brown/white color scheme.

That is one cool bathroom! I'm no expert but I would take everything off the wall and don't put it back... new painted wood cabinet with mirror in the same color as the darker tub tile, paint walls same color but a few shades lighter. New light fixture. Art above the toilet. If that's a mirrored shower door I'd switch it out as well. I can hardly wait to see what you do!

I now see cabinets on the wall opposit the sink so you could also just hang a framed mirror instead of a cabinet.

Wow, that's some 90's bling going on there! ;) Just paint some neutral color that blends with the creams for now. Or maybe - my personal favorite - pale blue or aqua. Might as well play it up. The pink clashes, in my opinion.

5 years is a LONG time. Can you paint marble?? I'd paint that sink & toilet ASAP & if you mess it up -- so what??? Or you can probably get a new toilet, sink medicine cabinet & lighting for under $1000 -- when you're ready to renovate (tile, floors, tub, etc) just reuse the items you bought.

You already got some very good suggestions, so all I can say is....Wow!!! You said the bathroom reflects what the rest of the house looks like. Can you post pictures of the other rooms? What is your plan for renovating the rest of the home?

Tub appears to be Kohler in Parchment. Rid yourself of all the harsh brass, walls in a shade of cream. LED bulbs in 4000k will help get rid of the "yellow". I've never seen a toilet like that, what is it made of, stone / acrylic / ???

I think white paint, an inexpensive new light fixture and the removal of the wall mounted paper towels and soap and you should be able to live with it. White towels and a white bath mat would be good too.

It will be fine. It's just a bathroom. And white paint makes everything a bit cleaner and nicer.

The house was built in 1954 but i think it's been renovated since. It is in north america, We thought about going with the seashell look of the marble and going bold with a palm tree, mural like, shower curtain, and painting the wall with shimmering pearl white to change the focus :D . But I'm exploring other ideas... also, the floor is not carpet, its another style of brown tile, you can see it on the picture close to the wall. My guess is acrylic for the toilet but I didn't have the honor to sit on it yet.

Use a yellow cream for the paint. I'd leave the medicine cabinet and light alone, same with the shower doors, because there's nothing you can do that will outshine that toilet and sink. If you have a few hundred dollars to replace both sink and toilet, the room will be well on its way to looking better.

Are you bathers or shower hounds? If bathers, or if there is a shower elsewhere that is not too inconvenient, I would remove the bronze mirror shower doors, as well as all the wall hanging items, including mirror and light fixture. Then prime the walls white and make your decision based on how much of a change that makes.

If you have to live with the tile, I'd change out what is easily changed until you are ready for the larger renovation. That toilet is massive (and kinda ugly) and it is going to use a LOT of water on every flush. Newer toilets use very little - some use less than 4 litres per flush and you can get dual flush as well. I'd make that change quickly and it is easily installed. A new white pedestal or small vanity with an undermount sink would be nice. Replace the mirror and the light fixture and take everything off the walls. Big box stores and even Ikea have very reasonable prices on vanities and mirrors and you'll be able to find a light fixture for less than $100 without too much effort. Get rid of the shower doors and replace with a shower curtain on a bar.

Paint colour, I think I'd lean into the colour of the current fixtures a bit. A light taupe colour leaning toward white. Maybe something like BM 1499 - White River, or BM 2112-70 - American White.

Some nice fluffy new towels and it should make the room bearable until you can tear it all apart.
