We’re planning our new bathroom and am in the market research phase! Some things I learned doing our last bathroom:
Heated towel rails don’t heat the room
White grout and small tiles looks crisp and clean but you will be in the shower with a toothbrush and bleach for the rest of your days
Teracotta tiles are great for hiding dust & dirt
What would you do differently? Do you love or regret anything? Our bathroom will be a decent size (approximately 3.5 x 2m) but not enormous (plenty of space for a large walk-in shower & bathtub).
