When I remodeled my house back in 1992 I did all 3 bathrooms differently. The master was traditional, the guest bath was somewhat modern and the powder room was Victorian. If I had to do again all 3 would be different. I personally prefer them being different.

I also like them to be somewhat coordinated, but not the same (I would find that really boring). In our two bathrooms, the flooring (pre-existing our purchase), vanity, light fixtures and countertops are the same, but the wall tile and mirrors are different, as are the shower curtains.

Why would they ?

I'm with xedos. If they are not right next to each other, who will notice? Even if they are both guest bathrooms, and a guest tries them both out, no one will notice, and if they do, it will be a case of "more to admire".

I don't think they need to match in anyway. But I do agree with previous posters that I prefer a cohesive look throughout a house. So I personally would not choose to do one in an ultra-modern minimalist style and the other in shabby chic.

Thank you to all who replied. I appreciate all of your points of view. I probably would not have gone with completely different styles. I am, however, leaning toward different colors of similar backsplash/wall tiles. I want a little more "wow"(drama) in my guest, and a little more "aaahhh :)"(spa) in my master. I was concerned that they should have same, since most builders tend to do that. I want a more decorator/professional look, but don't want to make a remodel "fashion faux pas".

Your plan sounds great to me.

I suspect that builders match the bathrooms to save on the cost of materials. It's also easier to use the same tiles than to try to match style but with different materials. My designer told me that each of the bathrooms should have different tiles. I've remodeled the Master Bathroom and Powder Room - I was thinking about using the left-over tiles from one of these rooms for the 3rd bathroom - but designer thinks it will look like I just wanted to use up the leftover tile.

My two bathrooms are as polar opposites as you can possible get! I'll explain: My bathroom (the master ensuite is light (but not white marble, hex floors and white/light gray paint light). Moonlight "travertine like" porcelain floors and walls, Seatones (blue, aqua and sea green) glass tiles, Giallo Ornamentale granite and a light blue ceiling. Dark vanity. Crystal glass sink. The master bedroom and ensuite are totally different from the rest of the house and we're ok with that. Those are private areas. The rest of the house is done in rich warm colors, rich browns, pumpkin, deep golds, plum, dark sage green, bronze and black. DH's bathroom flows with the look of the rest of the house. His granite is mostly black, deep orange, dark gold. His glass sink is a Colbalt Copper color. Floor tiles and tub/shower surround is dark charcoal (basically black with accents of tumbled crema marfil and ORB metals). The walls were just finished today. A beautiful spanish knife texture with a glazed faux finish. Color is reddish bronzed over dark gold base. This is also the bathroom guests will use. It's bold and dramatic. He likes it. I like it too but I much prefer the tranquility of the Caribbean inspired color palette in my bathroom. So yeah, I have no problem with bathrooms looking TOTALLY different <g> Oh, they ARE on opposite ends of the house :)

My bathrooms don't match nor do my bedrooms. There is cohesiveness between all the rooms but nothing matching. I've got to much personality to display as DH says. Haha

I like your plan. I'm doing two bathrooms as well and am trying to do the same as you. Have them go together, but not match.

The advice I was given was just that "they should look like they're in the same house." Yes, it's subjective, but I think it's what people mean by "cohesive."

No, they don't need to look alike at all! I don't really even see any point in them being cohesive -- you can't see them at the same time.

From a practical point of view, I can see that it might be easier for you to buy just one tile. You might need to buy fewer "extras" in case of breakage during the work. Also, I think most of us are smart enough to tuck away a few tiles in case of damage in the future ... if your tiles are all the same, you'd need to save fewer.
