Hello, dear client.
The shape of the bathroom can be much better if we make little adjustments.
Hope you understand the new layout proposed, and enjoy your new bathroom.
The finishings are all ceramic porcelain tile, very resistant and versatile. You can find options in a big range of prices.
I suggest you choose for a local and tradicional brand, for quality and easy replacement.
Big formats work better, but in the shower area you can choose something smaller, with a rustic texture.
Please fell free to send pictures of your choices, so I can render again until you are completely satisfied.
For the ceiling, I suggest that it be aligned, in a new and white plaster.
This way you can ask for a plaster holding, that will give a good impression of light in the shower area (I suggest to locate this light over the shower, but make sure you request a water resistant installation).
On the top of the sink, I suggest a pendant lamp, in a copper or old gold colour.
One more light fixture at the ceiling is necessary, and I suggest a simple built-in lamp right on top of the toilet seat, for general illumination.
The mirror is probably custom made, with a led ring all around it.
For the faucet, the shower, the paper and shower towel holder, I chose black mate finishing.
The lavatory towel holder is built-in the cabinet, which is also custom made for better fitting, and I will provide you w/ the measures.
Best wishes!
