Nothing is 'timeless' except maybe penny hexagons and subway tile. The marble is organic but the other tiles you showed are rigid geometrics.

Please no tile rugs. They are just busy looking.

I would not do a separate tile inlay.

i think it would be pretty if kept simple, like an outline not a replacement of the main tile.

I can't quite make sense of your layout though -- how do you get into the shower (which I think is upper-left)? and why would you make such a claustrophobic little closet for your toilet when your bathroom is huge? could you move the entry door a bit to the left to make the toilet room less terrible to use?

@acm We are designing this remodel to ”age in place.” We only want to do this once. The water closet is actually bigger than what it appears and is required for code. It gives us room in case we ever end up needing assistance with mobilty. The entrance to the shower is next to the vanity area.

The water closet is very small in front of the toilet, where you might need help getting up and down, and very wide from side to side, where you might otherwise have hand rails to help with transfer and other things. It also has a very narrow doorway, which means if somebody falls, you will have a heck of a time getting in there to get them out. And a person with a walker would have a real challenge moving it into position and then out of the way. This is all coming from the perspective of somebody who's actually helped with caretaking...

Also, where are you putting a towel when you shower? on the vanity?

Sorry but nothing about that layout says aging in place.

The "tile rugs" can look nice ... until you start using bathmats at the shower/sinks and then you cover up some of the "tile rug" design and ruin the look by making it look busy/messy!

I like a tile inlay concept. Keep it simple and think through the TOTAL ROOM finishes.

I like tile inlays and rugs but not in this space and not with those tiles.

I like fully exposed rectangles in nearly symmetrical spaces with the larger tiles in the middle and the mosaic around the border.

I wouldn’t do it. A border around the edge was/is very 1920’s era, but there are so many gorgeous tiles, the “center inlay” look is unnecessary.

I just worked with an occupational therapist who does home design for age in place spaces. She said to use changes in tile to delineate changes in a space - different tile for shower floor for example. As you get older, you may be confused, may have vision problems, and flooring should cue you for the function of the area you are in. For that reason, I would not do the tile rug. (When my father-in-law was in a dementia assisted living unit, they painted black outlined rectangles in front of the elevators because residents were afraid to step in to them and it helped to control residents from wanting to get on the elevator and wander off.)

I would say that toilet area is far from ideal, especially given how much room you have had to work with in this layout. I'd go back to the drawing board on that one for the very astute reasons acm listed below.

The occupational therapist said it was best to have to put a towel on a hook outside the shower or resting on a sink outside the shower and not to put it on a towel bar - not even on an ADA towel/grab bar. She said that grabbing a bar with a towel on it actually makes the bar a slippery object to grasp and can cause a fall.

Love your basket weave tile!
