(2 p.m. BST) -- P&O Cruises has revealed details on flagship Britannia's forthcoming refit, which will include a new art gallery, a Dixons, more high-end shopping brands and a completely refurbished Atrium.

This is the first major refit for the 3,647-passenger ship which launched in 2015. Britannia will go into dry dock on October 7th and return to service on October 23rd.

The details first came to light on the Cruise Critic message boards with the following post from member officeboy:

For her next chapter, P&O Cruises are maximising your favourite areas on Britannia. The atrium will be given a new lease of life to create a lively social hub at the heart of the ship. There will be a new colour scheme and a fresh design direction, relaxed entertainment and a lively scene with music and informal performances under the starburst chandelier.

Deck 7 on Britannia
The Java café on deck 7 will now serve alcoholic drinks. 

The photo gallery will also be getting some TLC, including the welcome addition of a Dixons electronics hub featuring the latest imaging, computing and audio tech from Amazon, Apple, Beats, Bose, Canon, Fitbit, GoPro, Microsoft and Sony, among others.

Deck 5 on Britannia
P&O Cruises are introducing a permanent new art gallery next to Blue Bar on deck 5 by the atrium.

The Market Café also on deck 5 has already benefited from new furniture and décor, and a brand-new menu including decadent ice-cream creations, made in exclusive collaboration with Hampshire dairy Jude’s.

Shopping on Britannia
Britannia will feature a host of new premium brands and a more interactive environment, including try-before-you-buy tasting tables and consultation areas in our beauty and make-up zones. Jo Malone, Tom Ford, Edinburgh Gin, Michael Kors accessories and exclusive fine jewellers, Clifton, will be joining the line-up.

Oasis Spa and Salon
Two ‘express spa’ pods will boast a range of treatments. In one pod, you’ll enjoy high-tech massages; in the other, a zero-gravity lounger will offer express skin treatments as well as LVL lash treatments. There will be two innovative new experiences in the thermal and hydro-pool suite. Brace yourself for the therapeutic benefits of the Arctic cold room and let everyday stresses ease away in the aroma steam room.
