I would keep it light and bright with a warm off-white or light beige porcelain tile for the bathroom floors. Find one that has a matching mosaic for the shower floor.

Thansk you! My internet locked up on me and I couldnt get my inspiration pics to load. So i was thinking creamy or light beige as well.

I wouldn't do an accent line/multiple lines/alternating square tiles. The first tile you've posted looks like Bedrosian Cloe Cream - except with less variation (Cloe is a V4 tile = the highest variation rating for a tile). If it is Cloe Cream, you need to look at more photos of it - sometimes people will tone down the variation between the tiles before posting a photo of it = you may be surprised when you see the actual tile.

In order to decide which tile to use for the surround, we need to see the floor tile + vanities that will be used.

I have done small tile in secondary showers, but wouldn't want it in my main shower with all that grout.

I haven’t picked the floor tile, that is one of the tiles I’m looking for. For vanity on the guest side I’m thinking something like this, but with a more simple countertop.

My side will be similar but with additional storage, probably a linen cabinet on one side

Do you really want tile? After having LVP ina guest bathroom, I would never have tile again.

Since the heart pine is the warm visual anchor, I would choose the bathroom tile as a bridge rather than trying to make it the main feature.

A warm off-white, cream, light greige or soft beige porcelain could work well here if the variation is controlled and the shower floor has a compatible mosaic option. I would be careful with anything too cool gray against heart pine, because it can make the wood and tile feel disconnected. I would also avoid a busy accent band unless the rest of the vanity areas stay very quiet.

Because both vanities are being replaced, I would look at the tile, vanity finish, mirror finish and lighting together. In a Jack and Jill layout, the two vanity zones should feel related to the shared shower/toilet space, not like separate decisions. A simple mirror shape and warm-neutral lighting can help the new tile feel calmer next to the pine.

From a manufacturing and QC perspective, I would also prioritize slip resistance, low maintenance and consistent tile calibration over a dramatic showroom look. In a rental-style apartment over a garage, durable and quietly attractive is probably the win.

I have always liked slate next to pine usually green or black . I do agree these decisions need to be made together not one at a time . Will you live alone ? I hate J&J baths I would be changing that before any tile choices are made but not sure how far your son wants to go. I also would not choose a mushroom wall color with pine .

The current floor is slate, but a mix of grays and reds. I will live here alone, but my grandkids will occassionally be spending the night. The layout of the bath will be staying the same, the vanity side on the other bath is also accessible from the hall so acts as a powder room on that side.

What color would you do with pine floors? I want to use the same color throughout as there are some angled walls. If I paint any room a different color it will be my bedroom as it is kind of it’s own space.

These are the current floors in the bath. While I love slate, I don’t love this slate.

This is the current living room/breakfast nook. Not my furniture.
