Uusally you do not use the same tile but there is always the same color to avoid any asymmetrical view.

Why a full bath ? Where is the bedroom that needs a full bath. IMO If you must have it then stop adding stuff that is not needed like the wall between the toilet and sink the bench no towel bars just hooks . Who are planning this bathroom for ? IMO the same flooring in that whole space is the answer.

Keeping the same floor tile everywhere will visually flow better and have a calming effect. This is not the area to make your designer statement, IMO, especially in such a small space.

@Patricia Colwell Consulting this is not our design, I was just using it to show the basic division of space. In our space, the bathroom is larger and extends out to about where the 'seat hooks' are; it also extends the full length. We will have an alcove tub, not a shower, with the toilet, a pocket door, and a double sink vanity. No towel bars. We bought an old Victorian house and it isn't in our budget to create an entirely new bathroom upstairs where the bedrooms are. This room is a newer addition and is ready to go- it has new drywall, new electric, and plywood floors (from previously owner). A full bath downstairs away from bedrooms isn't ideal, but it's what works for us with our current budget/timeline/house layout.

I agree with others that you should use the same tile in both spaces as it creates less visual clutter.

Obviously having a downstairs shower isn't the ideal but it exists in the event someone wants to use it and the incremental cost of adding a shower isn't that high - there is a basic cost but unless you go for high end finishes, it isn't unreasonable and if it works for your current needs - why not? And while I am not one to advise making choices based solely on resale to mythical buyers in the future, I think many people who are realistic about older homes and their foibles and drawbacks would think an extra shower was positive.

I have a shower in my guest bath in my one bedroom condo. I don't have a lot of overnight guests crashing in my living room because I am past the age when people want to sleep on a sofa instead but it has been used in the past. A home probably has more people and it is likely that at some point the abiity to take a shower at the same time as others are doing would be a good thing even though they might have to take a walk in their bathrobe - the horrors 😱😂🤷🏼‍♀️

@Helen I am convinced by everyone in this thread to do the same tile!

Upstairs has two bedrooms and one open room off of the stairs that was probably once a sitting room. We may frame it in to make 3 beds as it already has its own closet and use it as a study. The bedroom above the laundry room (also part of the newer addition) has its own tiny tiny bathroom so we'd make that the guest room so they can have their own bathroom. And then we'd use the bigger bath downstairs. Not ideal, as you said, but I'd rather have me walking around in my bathrobe than my guests!

Is this a one bath house with only a small bathroom upstairs?
