A steel bathtub in a grey carpeted bedroom and a marble bath positioned on a wooden plinth are included in Dezeen's latest lookbook, highlighting luxurious bedrooms with bathtubs.

Typically confined to bathrooms with splash-safe surfaces, a bathtub in a bedroom has an air of grandiosity and indulgence.

It is often seen as an impractical design trend due to ventilation considerations, the need for a strengthened floor and the transition of moving from a soapy bath soak to fresh bed sheets, but this roundup showcases different ways baths in bedrooms have been achieved in homes and hotels.

This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring cherry red interiors, minimalist bedrooms and concrete kitchens.
