The 38-year-old shares her house with her husband Chris Martin and their two children, Apple, seven, and Moses, five.
And the Glee star says she has a Antonio Lupi Baia bathtub situated right in the middle of her and the Coldplay singer's bedroom which she loves to relax in.
In an article in Elle Decor magazine which lists the 12 things she can't live without, Gwyneth said: 'It's in the middle of my bedroom - perfect for a relaxing wind-down and for bathing the kids.'
Paltrow also has a 'Juxtaposed: Religion Shelf', which contains holy books which compliment her Penguin Classic books.
She said: 'My Juxtaposed: Religion Shelf has built-in slots which hold holy books - including the Qur'an, Bible, and Tao Te Ching - all at the same level (which is how I like to think about religion).
'I have gorgeous editions of Penguin Classics that make the books so tempting to pick up, again and again. The ultimate cure for sore muscles.'
