The ideal height of your bathroom cabinet depends on a bunch of different things, including the cabinet's size, the height of the users, plus the overall design and layout of the bathroom. However, a common guideline is to position the bottom of the cabinet at a height of around 80 to 90 centimetres above the bathroom countertop.
Absolutely not! If you're into creating a themed aesthetic (whether through a design style or colour) throughout your home, that's your choice. However, you can also go for a completely different vibe in your bathroom. It's up to your personal taste.
The size of your mirror cabinet in relation to your vanity is a matter of personal preference and the specific design aesthetic you're going for in your bathroom. While there is no strict rule, many designers aim for a sense of visual balance and harmony in the bathroom. A mirror cabinet that is slightly narrower or the same width as the vanity tends to create a balanced and cohesive look.
Shaving cabinets (or medicine cabinets as they're sometimes called) generally sit centred above your sink or vanity in the bathroom. Most people find this the most aesthetically pleasing choice, but it's not a hard and fast rule - you can place it off-centre or even adjacent to the vanity if it's a large piece of furniture.
