I have a large master bedroom in a darker teal blue and a small master bath in a very light sky blue. I have never felt the need for the two to be the same.

Bathroom is very neutral with mostly beige/white colors. Bedroom has expensive wallpaper, that would not be durable in a bathroom. Lots of bright colors in the bedroom. Also never felt the need for the two to be the same.

They don't need to be the same color. In my case, they are the same color walls, simply because I was tired of picking colors throughout the house!!

Different. Bath is SW Passive (light gray) and bedroom is Rain (pale aqua blue). The decor coordinates between the 2 rooms, though. And I do have a print in both rooms with the same subject, different design (birds).

The bath should reflect the colors used in the MBR but it need not be the same, and often should not be. It must harmonize.

Ours are the same color. We had chosen the color (BM Aura in Constellation) to use in one of the rooms, and ended up liking it best for both. We did try a few other options (paint samples/swatches) for the bedroom, after we'd used Constellation in the MB, but didn't like any of them as much.

I saw a Houzz photo where the bathroom was a deeper shade of the bedroom in the blue-green family, like they were from the same color strip. It was very pretty.

We used the same color (BM Aura in Pashmina), and the look is totally different due to the natural light. Pashmina is a greige color, and blends with the MB tile selections, and is bathed in (south and west) light all day. Very glow-y and restful. The MBR, unfortunately, has two north-facing windows (with tall holly outside for privacy) and, consequently, is quite dim. I don't think changing the wall color will help, so I am working on lightening up our furniture and bedding. Lesson learned: Consider the natural light before settling on colors.

Nothing helpful (I will never have a master bath, wah!) but I am completely amused by the bathroom helpers in the photos above!

Mine don't. Bedroom is very dark and bathroom is light and cheerful

abbycat9990: thanks for your post. We just finished a gut-reno of our master bath, painted it BM Horizon. LOVE it - its a light gray most of the time, but can look dusty green or dusty blue sometimes. BUT: tried it in the master bedroom, as well as dining room and kitchen, and its completely different color - never light gray (which is what I want).

I love the idea of having just 2 or 3 total colors on the walls in the entire house, but I want gray in several rooms and it looks completely different.

Debating whether to still paint master bedroom Horizon, even if it will look gray or blue, in contrast to the gray looking master bath.

My mother who wasn't a professional, used to say pick a color palette of 3-4 colors and use those colors in different amounts throughout the house. So if you chose a palette of say soft green, tan, red and white. Then use the other colors as accents in a 60/30/10 formula.

Nothing wrong with mixing up colors. The colors should coordinate a bit so they flow from one room to another.

My master suite is three rooms in an "L" shape, the sitting room is in the middle. All three rooms are open to one another with doorless archways, so they do flow visually.

The center room, the sitting room, has deep red/burgundy walls and a cream/ivory trim color.

Off one side of the sitting room is the bathroom. The the trim and cabinets are the same cream/ivory as the sitting room, but the wall are somewhat beige.

Off to the other side of the sitting room is our bedroom. In there the walls are sort of a cream/ivory, and the trim/cabinets/wainscot is a deep muted historical green.

The cream/ivory sort of ties the three rooms together and the other colors sort of bounce off that.

For bathrooms which can be dominated by hard surfaces (fixtures/tile/stained wood) where the color of those items can be difficult or expensive to change, I usually recommend that those hard surfaces be a neutral or somewhat muted color. Then the wall color, or soft accent items like towels and throw rugs, curtains, etc, which are easy to change, be the stronger and sometimes more vibrant accent color. The hard surface colors in our bathroom are sort of neutral (cream cabinets and trim, beige walls, natural teak for the countertops and tub deck, tile is cream and charcoal), we change the color of the towels/rugs whenever we feel like it. Sometimes to a strong color; deep green, cranberry red, etc, sometimes to a soft neutral like beige, off-white, etc.

And there is nothing wrong experimenting with colors either, especially paint. At roughly 10 cents a square foot coverage for basic formulations, paint color can be inexpensive and fairly easy to change.
