Princess Cruises Sphere Class: A New Era at Sea

Princess Cruises’ Sphere Class ships mark a bold new chapter for one of the world’s most beloved cruise lines. Designed to elevate every aspect of life at sea, the Sphere Class introduces a new generation of Princess ships, combining striking architecture, immersive entertainment, refined dining and seamless onboard technology.

In this guide, you’ll discover what defines the Sphere Class, explore the ships leading the way, uncover the standout onboard features and learn how Princess MedallionClass brings the experience together.

What is the Princess Cruises’ Sphere Class?

The Sphere Class is Princess Cruises’ latest class of ships, created to redefine the modern cruising experience. These ships are designed from the ground up with guest comfort, immersive spaces and flexible lifestyle experiences in mind, offering a fresh interpretation of what cruising with Princess can be.

Rather than simply being larger, Princess Sphere Class ships focus on how space is used. Expansive public areas, light-filled interiors and carefully curated venues are designed to feel intuitive and relaxed, whether you’re enjoying a quiet coffee with ocean views or settling in for an evening show. The result is a cruising experience that feels contemporary, refined and unmistakably Princess.

The Sphere Class also signals the future direction of Princess cruise ships, with innovation, sustainability and guest-centric design shaping every detail across the class.

Sphere Class ships: Sun Princess, Star Princess and beyond

The Sphere Class is a growing family within the Princess fleet, with multiple ships bringing the concept to life.

Sun Princess: The first Sphere Class ship

Sun Princess is the inaugural Sphere Class ship, setting the standard for what this new generation delivers. From the moment you step onboard, the design feels open and forward-thinking, with flowing layouts that encourage exploration and connection.

This ship introduces the core Sphere Class features that define the experience from reimagined public spaces to elevated dining and entertainment. It also reflects Princess Cruises’ commitment to creating ships that feel welcoming and easy to navigate, offering both lively social areas and quieter spaces to retreat and relax.

Star Princess continues the Sphere Class vision, reinforcing that this is a long-term evolution of the Princess fleet. With the same design philosophy and next-generation features, Star Princess expands the Sphere Class experience across more itineraries and regions.

Princess Cruises has indicated that the Sphere Class will shape future ship development, meaning more ships are likely to join the fleet in years to come.

Standout design and architecture

One of the defining elements of the Sphere Class ships is the architectural approach. Every space is designed to feel purposeful, open and connected to the ocean.

The Sphere and next-generation public spaces

At the heart of each ship is the Sphere, a striking central space designed to anchor the ship’s social life. This area brings together dining, entertainment and gathering spaces in a way that feels immersive rather than overwhelming.

Natural light, sweeping sightlines and thoughtful layouts create a sense of flow throughout the ship. Instead of feeling compartmentalised, public spaces transition smoothly from one to the next, encouraging you to explore at your own pace.

Elevated outdoor spaces and ocean views

Outdoor spaces are a major focus across the Sphere Class ships. Redesigned pool decks, open-air promenades and thoughtfully positioned seating areas allow you to enjoy uninterrupted ocean views throughout the day.

Whether you’re watching a sail-away event, enjoying a quiet morning on deck or soaking up the atmosphere by the pool, Sphere Class ships are designed to maximise your connection with the sea, no matter where you are onboard.

Dining experiences across Sphere Class ships

Dining has always been a highlight of cruising with Princess, and the Sphere Class ships take this reputation to the next level.

Main dining and specialty restaurants

Across Princess Cruises’ Sphere Class ships, dining venues are designed to feel more intimate, flexible and refined. Main dining rooms feature elevated menus and elegant settings, while specialty restaurants offer immersive culinary experiences inspired by global flavours.

The focus is on choice and quality, allowing you to dine when and how it suits you, whether that’s a relaxed evening meal or a special celebration at sea.

Casual dining and all-day options

Sphere Class ships also excel when it comes to casual dining. Cafés, laidback eateries and grab-and-go venues are positioned throughout the ship, making it easy to enjoy a coffee, light bite or sweet treat whenever the mood strikes.

These venues support a casual cruising style, giving you the freedom to shape each day without feeling tied to formal dining schedules.

Theatre and live performance spaces

Purpose-built theatres onboard Princess Cruises Sphere Class ships showcase large-scale productions, live performances and innovative shows designed specifically for these venues. Enhanced staging, lighting and acoustics create a theatre experience that feels both intimate and impactful. Shows are curated to appeal to a broad audience, blending storytelling, music and performance in a way that feels modern and engaging.

Lounges, music and evening venues

Beyond the main theatre, Sphere Class ships feature a range of lounges and live music venues. From relaxed piano bars to lively evening spaces, these venues invite you to unwind, socialise or simply enjoy the atmosphere as the day turns into night.

Wellness, relaxation and onboard lifestyle

Princess Sphere Class ships place a strong emphasis on balance, offering spaces that support both activity and relaxation.

Spa, fitness and wellbeing spaces

Wellness facilities onboard are designed to feel calm and restorative. Spas offer a range of treatments inspired by global wellness traditions, while fitness centres provide modern equipment and spaces to maintain your routine at sea. These areas are thoughtfully positioned to feel like a retreat, allowing you to step away from the energy of the ship when you’re seeking a quieter moment.

Pools, adults-only retreats and quiet spaces

Multiple pool areas, adults-only retreats and peaceful corners give you plenty of choice when it comes to how to spend your time onboard. Whether you’re looking for a social poolside atmosphere or a secluded space to relax with a book, Sphere Class ships cater to a variety of moods and preferences.

Princess MedallionClass: Technology that transforms your cruise

While Sphere Class ships introduce a new era of design and onboard spaces, they also feature the groundbreaking Princess MedallionClass, a technology platform used across the wider Princess fleet.

The wearable Medallion streamlines the cruise experience from start to finish, supporting faster check-in, keyless stateroom access and cashless onboard payments. It also enables personalised service and convenient food and drink ordering throughout the ship. On Sphere Class ships, Princess MedallionClass works quietly in the background, letting you focus on enjoying your cruise rather than managing logistics.
