you can either go for darker grey tiles or a beige. It all depends on how grey your wall tiles are and if they have any underlying colours - are they are purple or green grey etc etc. How does the ventilator affect the look. Do you have a photo?

Hi! Yeah it will. You will have to get your plumbing lines capped and replaced. It's not advisable to have a joint in the plumbing line. So the one that you are wanting to pull to the new sink will need a fresh line put in from the last bend it has. I hope that makes sense! Best! Miloni

Just to clarify, changing the direction of the comod would give you more space outside the cubicle door. This is however considering you get a smaller tub, it would otherwise be difficult to mount. The present location of the comod seems inconvenient since it does not leave a lot of room and cannot be flipped in lieu of the column. If you can device a way around it, the plan is good. Di consider an independent, standing basin. They look good and take up lesser space. There will however be lesser and not to mention separate slab space.

For a cohesive look, it's recommended to use the same Onyx color/pattern for both the vanity counter/sink and the shower walls. However, incorporating complementary colors can add visual interest and depth to the bathroom design. Consider using similar tones or coordinating patterns to achieve a harmonious yet dynamic aesthetic.
