I would use a fairly solid colored stone look tile.

If your home has hardwood, please do not add fake hardwood looking stuff to this room. It never looks right.

That being said there are some IMPRESSIVE travertine-looking porcelain tiles out there. They are very handsome and they come in every colour imaginable. I would have a look at the stone-looking porcelain tiles that would work with with the space AND the hardwoods that exist elsewhere.

The slate examples above are another example of a stone-look porcelain that will look intensely beautiful without having "fake wood" sitting right next to the real deal.

I just read that terra cotta tiles will be coming back; might want to keep them.

Thank you for the comments---Unfortunately even when terra cotta tile comes back I won't like it... to me it only looks right in a sun filled country in a old restored house or farmhouse! I went and looked at tiles yesterday and was most attracted to washed concrete look porcelain tile, and some tiles that looked like stone very linear- but soft tone within tone. see below.... is that a better direction or go more beige, less taupe? Its such a massive room (700 sq feet with such a transitional- industrial farmhouse meets Nantucket feel

Just realized in the broader scope of things, that this room serves to join the old part of the house which is all dark stained and natural pine floors on one side (see pic below) and on the other side of the doors leads out to the garden with a bluestone terrace. What direction do I go in that will not be too busy- integrate , and be durable and good with dogs and water? Painted brick? cement washed porcelain tile? pale solid color tile?

HELP!! thank you!!!

I would make the flooring consistent to what would have been used in the twenties on a sunroom floor and to incorporate a Hampton look I would try to coordinate with the bluestone patio. If budget allowed, I would use a blue stone tile. This is the tiled look I am envisioning to make it more constant to a 20s sunroom porch.

Porcelain is a great choice for durability. Without seeing your other floors, I like these two bottom tiles from your list, especially the left one. Could you show the adjoining spaces flooring?

I would stay away from something with an obvious pattern, like the first one you posted. It is such a big space, tile with a pattern is going to be a very prominent design element.

You've had terra cotta tile bossing the room around all these years, I think you will be much happier with a quiet floor. BTW, you've done a great job decorating with the terra cotta.

Bring the tile boards home, that might help you decide. I would also put thought into the grout and pattern as they will be be design elements as well.

I would do the one on the right with no pattern. It's too dizzying.

I like the idea of a grayish blue tile to complement the bluestone patio.

I really appreciate this! Pic of stained wood floor in the adjacent desk area leading to two steps (ignore carpet that is being removed as well) that are going to be remodeled or painted black with a seagrass tread below. this is the next area to tackle! I like the idea of making the whole space more of a sunroom space- and 20's era- with the bluestone or grey large format tile sounds really good! I am assuming I need to make the grout to match to reduce the dizzying grout lines in such a big space?

Thank you all so much for the help!! its such a big investment!

Hah! I have similar to that orange tile on the master balcony, and I hate it too. DH picked it.

The bluestone look seems so much more appropriate for a 1927 Four Square.

Bluestone or brick!

Blue stone

Thank you all! I'm going to find a bluestone porcelain tile that is more grey than blue, and a grout that is matching rather than light to reduce the amount of grout lines.. questions:

1) what size? 12 x 24? Larger yet?
2) what pattern? I'm leaning towards on the diagonal or should I go more classic?
So excited!!
