It's a personal choice. You will have to seal them. Personally I would never put marble in the shower, but several people do. Search marble showers on here & read what people say. There have been tons of discussions about it.

They're 1/3 offset, so of course every third tile will be quite small. It looks like your right wall isn't quite plumb, so they did the best they could to make the pattern work. The actual laying and the matching of middle and side walls looks excellent. This is a great time to use tile-matched grout, though, instead of something with a lot of contrast. Old houses don't do well with finish choices that play up their imperfections...

I would love to see your unconventional master bath!! Our plan started with a first-floor master bedroom /bath plus an extraordinarily poorly placed powder room. You noted above that you don't like cleaning bathrooms -- I'm with you on that. Since it's just me and my husband most of the time, I don't see the point in two toilets on the first floor ... so we moved the powder room next to the master bath and removed the toilet from the master bath. So we're planning the powder room to be adjacent from BOTH the master bedroom AND the main house ... and then we have the bathing facilities separate. Unlike toilets-shoved-in-closets, the powder room is 5' the short direction, so it's large enough for comfort, and I only have one toilet to clean on the first floor. I've removed the other parts of the house, so it looks kind of confusing ... you'll have to trust me that it fits in nicely with the rest of the house ... at the foot of the tub, that's a little ledge and a TV for my husband ... that's a linen tower to the left of the vanity ... that's the shower head floating in mid-air /obviously it'll be attached to the wall: I definitely see your point about two standard bathrooms being more economical, just trying to figure out for myself if I was thinking of doing something different for the sake of being different or if it would actual make life easier for my family! Walking yourself through various options is a good way to determine that. We personally are sold on the above bath layout because my husband likes to stay in the tub for hours at a time (he often "reserves" the tub before a, so we decided it makes sense to place the toilet close-but-separate. Also, what computer program are you using? :) HGTV Home and Landscape Platinum Suite. It's nothing special. I drew up your latest suggestion in this program. Concerns: - If you're trying to have kids share, you need a sink in the toilet closet. Otherwise, you still have a problem with the kid in the toilet closet coming out and having no sink available to him ... if you're going to do a toilet-in-a-closet, I'd put a small pedestal sink in there too. - You have a bottleneck in the sink area. If the kids are using this area at the same time, you're going to have people trying to squeeze past people at the sink. - I forgot the exact square footage and have already cleared it out of my computer program, but it was in the 130s ... so it's still bigger than two simple bathrooms and has water walls spread around. However, if the access is off a common hallway, having two baths right beside each other seems silly to me I think the two baths side-by-side appear silly because they're floating in mid-air. If we had a whole floorplan and could see one bedroom to the left of the back-to-back baths /two bedrooms to the right of the back-to-back baths, it'd look different. It'd look like the bathrooms each "belonged" to those bedrooms, though they're accessed through the hall. Mrs. Pete has some great ideas. keeping your water from the same source, but with two separate you'll definitely have an easier time selling. best of luck! I agree that most people would be attracted to two plain bathrooms rather than a "creative" layout. With resale in mind, here's a question: How long do you anticipate staying in this house? If you're going to move before the kids are teens, I'd say go with one simple bathroom. One bathroom would be enough for them until they start in with make-up /hair and shaving. I think that a girls bath and a boys bath might be nice - perhaps the girls bath has one sink and more storage / makeup area and a tub and the boys get 2 sinks and a shower unit, etc That'd work fine if the OP ends up with a nice even split of 2 girls and 2 boys ... but since half these children aren't even conceived yet, that's a guess.

I was surprised when I went to pick paint for the master bathroom and master bedroom. I thought I was going to easily go for a very light blue gray like I have in some other areas of my house. But the lighting just didn’t make those colors look good. So sometimes you have to be flexible and go for a different undertone. In my case it was going more towards the green undertones, like North Texas says. You just need to be flexible and find the undertone that looks best with your lighting.
