Master Bath with Black Granite Vanity and Agate Wall

The arched top on the mirror is the one soft curve in a room full of straight granite edges and square tile. It sits against a dark stone slab that runs up the wall as the splash. Without the arch the vanity zone would be all hard lines. The shape is a small move, but it stops the corner feeling boxy and matches curved details used elsewhere in the home.

The compartment behind the door has a brown and gold agate-pattern surface on the upper wall, with black tile below and across the floor. The pattern is book-matched so the veins mirror each other, which is what gives it that big feature look. It turns a small toilet cubicle into the most decorative part of the bathroom. Keeping it to one zone stops the pattern from overwhelming the whole space.

A wall-hung toilet with a concealed cistern was chosen so the floor runs clear underneath it. That makes mopping the black tile far easier, since there is no base to clean around. The cistern hides inside the wall behind a dual-flush plate, which keeps the look clean and saves water. The trade is that the carrier frame must be built into the wall during construction, so it is a planning decision, not a later swap.

It is a wet-dry layout. The vanity and mirror sit in a dry zone outside, and the toilet has its own compartment behind a wood-framed door. Splitting them means the counter area stays dry and usable while the wet zone is closed off. In a shared master bath this lets two people use the space at once. It also keeps damp away from the wood vanity cabinet.

It is, and that is the honest cost of this look. Black granite and dark tile show every water spot, soap smear and dried droplet in a way white surfaces do not. You will wipe the counter and glass down more often to keep the shine. Use a squeegee after use and a pH-neutral cleaner, not an acidic one that can etch the granite. The payoff is a room that looks nothing like a standard white bathroom.

The big line items here are the granite counter, the book-matched agate wall and the wall-hung toilet with its concealed frame. The agate is the swing factor, since a genuine stone slab costs far more than a large-format tile printed to look like one. If you want the effect for less, use a patterned porcelain slab on the feature wall and keep real granite only on the counter. Get the counter and toilet frame priced before the finishes.

Yes, and the wall-hung toilet actually helps in a tight room because the clear floor makes it feel bigger. Keep the dark stone to one feature wall rather than wrapping it around, or a small room will feel closed in. A black granite counter and an arched mirror carry the style on their own. The separate toilet compartment needs a little more width, so in a very small bath you may drop it and keep one open zone.
