You could make the travertine look more modern and up to dat by painting the trim ceilings and walls in a new more modern color,updating lighting a bulb wattage

I would either gel stain the cabinets a dark color or paint them white

I have travertine in all areas except bedrooms and living room
I wanted to put in a grey slate type tile in that extra bedroom, What do you think ?
There is a mst bedroom directly across the other side of the hallway, would that room have to be the same floor ?

there is no "have to be" just what you like. I think it would be ok to have a different floor in the living room if it's already different from the hall -- wood fine, slate fine, as long as you don't live in a cold climate where the tile would freeze you in winter.

One side is mst bedroom across the hall is guest/reading tv room
Would two different floor types look weird
I wild like to keep carpet of some type in mst bedroom
Ideas please

Can cork has already advised you that same floor is best,and that different floor will look themed, stay the same

Keep the travertine,. Is that a cabinet with a sink? If so, add a small rug for texture.

your question has been answered. It may not be the answer you hoped for, but it's the best design option for your situation. carpeting IMO is just gross. travertine is a classic choice.

That's a pretty floor! Unless it is a very large house, it is best to have the flow of all one floor, otherwise it looks choppy. Travertine, wood, and carpet, it is sounding very broken up.

I would paint that cabinet. Unless my monitor is off, it also looks like the walls need to be painted a color that goes better with the travertine.

You can absolutely put a wood floor next to the travertine, and it will be softer and warmer in a bedroom than the travertine. I would not use a different tile or hard surface though. If you want to do that, then stick with the travertine.

I think the travertine is lovely. I would invest the money you'd spend taking it out and installing a new floor in purchasing some really nice area rugs. But absolutely go ahead and either stain the cabinets dark or paint them, and I agree that updated paint colors would make a big difference as well.
