P&O Cruises’ Iona ship will feature destination-themed treatments, whirlpools and a salt steam room when it launches next year.

Two treatments – the Nordic Cleanse and the Baltic & Ice Massage – available on the ship have been inspired by Nordic hot and cold therapies.

The ship will sail itineraries to and from the Norwegian Fjords in its maiden season.

Passengers will be able to spend up to 45 minutes in the salt steam room –  a first for  P&O Cruises – and access two Infinity Whirlpools in the open-air deck area, The Retreat.

The line will also debut a spa shop dedicated to skin, body and hair care on Iona, which launches in May 2020.

P&O Cruises president, Paul Ludlow, said: “Our new spa on Iona will be ideal for those looking to make the most of their ‘me-time’.

“From a restorative steam in our new salt room, to the relaxing qualities of a Nordic-inspired massage, guests will certainly feel the benefits whilst relaxing in this stylish space.”

A new range of group classes, including indoor cycling and meditation, will also be available on Iona.

Glasgow-born Wesley Dunlop will captain P&O Cruises’ new vessel – four years after he first joined the line.

Dunlop said: “To be at the helm of the largest, most innovative, most environmentally friendly cruise ship ever built for the British cruise market is the ultimate honour for any captain.”

He has also captained Aurora and Britannia during his time with P&O Cruises.
