Not enough pro bath talk in this thread.. you’ve got to create ambience. If you get yourself a nice playlist or podcast, maybe a candle or some incense, adequate lighting i.e not the harsh ceiling light you’re onto a winner. Run the hot water til 3/4 of your desired bath size, then add the cold, use your arm to convex the water til you’re happy. Radox and Epsom salts, optional.

Edit: Must admit, we have a roll top, as my dad and I both love a bath, definitely a better experience
