The Sims 4: Island Living is a paid expansion pack for The Sims 4 from Electronic Arts and Maxis, priced at around $39.99 USD as a standalone expansion (often included in larger Sims 4 bundles at a discount). There’s no official free full download, and it requires the base Sims 4 game to play — this guide covers the legitimate install steps, requirements, and an honest look at whether the tropical island life fantasy is worth adding to your Sims collection before you buy.
What Is The Sims 4: Island Living?
Island Living transports your Sims to Sulani, a tropical island paradise inspired by Pacific island cultures, where the pace of life slows down and the focus shifts toward ocean activities, community spirit, and environmental stewardship. Sims can swim and dive in open water for the first time in The Sims 4, explore reefs and shipwrecks, surf waves, and even discover an entirely new life state: mermaids, complete with their own unique abilities, needs, and hidden underwater lifestyle.
Beyond the mermaid life state, the expansion introduces a light environmental system where the island’s happiness and cleanliness respond to how residents treat it, encouraging players to organize community clean-up events, protest polluting businesses, or lean into an eco-conscious lifestyle if they choose. It’s a noticeably more relaxed, community-driven expansion compared to some of The Sims 4’s more career- or drama-focused packs, leaning into slower island rhythms, local festivals, and found-family storytelling.
How to Download The Sims 4: Island Living (Official Steps)

- Open the same platform and search for “The Sims 4: Island Living”.
- Confirm the listing is published by Electronic Arts / Maxis.
- Click Buy and complete checkout for the expansion pack.
- Let the platform download and install the expansion, then launch The Sims 4 — Island Living content will automatically appear in Create-a-Sim and Build Mode.
Sulani, Mermaids, and Island Life Systems
Sulani is built as an open, multi-neighborhood island world with beaches, cliffside villages, and a bustling waterfront market district, all connected without traditional loading screens between areas within the island itself. Swimming, diving, and boating are core activities here in a way they aren’t elsewhere in the base game, with Sims able to freely explore open ocean water, collect treasures from sunken wrecks, and interact with sea life ranging from friendly dolphins to more mysterious, mythical creatures tied to island folklore.
The mermaid life state is the expansion’s headline feature: Sims who become mermaids gain a hidden tail and unique swimming abilities, must manage a special hydration need, and can perform influence-based mermaid powers that affect the environment and other Sims around them. This life state exists as an optional layer on top of standard Sim life, letting players mix mermaid storytelling with the more grounded, community-focused Sulani gameplay as much or as little as they like.
Environmentally, the island’s overall condition shifts based on player choices — allowing polluting factories to operate freely will visibly degrade the island’s beaches and water clarity over time, while community clean-ups and eco-friendly choices restore it, giving the expansion a light simulation layer that ties gameplay choices to visible, persistent world changes.

Who Should — and Shouldn’t — Play The Sims 4: Island Living
How Island Living Compares to Other Sims 4 World-Focused Packs
The Sims 4 has released a number of expansions built around a distinct new world or setting, and Island Living stands out among them for how deliberately it slows the game’s usual pace down. Where many expansions add new career paths, complex social systems, or fast-moving drama mechanics, Island Living leans instead into relaxation, community connection, and environmental storytelling, making it one of the more meditative additions to the game’s overall catalog. This makes it a particularly good fit for players who enjoy The Sims 4’s more atmospheric, slice-of-life storytelling rather than its more systems-heavy career or occult-focused expansions.
At the same time, this slower pace means Island Living is often recommended as a complementary pack rather than a first purchase for entirely new players, since its content shines brightest layered on top of an already-established Sims 4 save with existing families, careers, and social relationships to bring into Sulani’s more relaxed setting. Long-time players frequently describe using Sulani as a vacation destination or eventual retirement setting for existing Sims rather than a first home base, which reflects how the expansion was clearly designed with an already-invested player base in mind.
Building and Decorating Sulani-Style Homes
Beyond its gameplay systems, Island Living contributes a substantial amount of build and Create-a-Sim content specifically themed around tropical, coastal aesthics — open-air living spaces, thatched and bamboo building materials, vibrant floral patterns, and beachwear that fits Sulani’s warm, relaxed atmosphere far better than items from earlier, more temperate-climate expansion packs. Builders frequently combine this content with earlier packs’ furniture and structural options to create homes that blend the island’s distinct visual identity with more familiar Sims 4 build conventions, giving experienced players plenty of room for creative combinations beyond what Island Living offers purely on its own.
The pack’s environmental systems also interact with build choices in subtle ways — homes built directly along heavily trafficked beach areas are more exposed to the island’s dynamic cleanliness state, meaning careful placement and community involvement can meaningfully affect how pleasant a Sim’s daily surroundings feel over time. This ties the pack’s building tools back into its broader environmental theme rather than treating construction as a purely cosmetic afterthought.
The Mermaid Life State: Long-Term Storytelling Potential
Beyond the initial novelty of a hidden tail and underwater abilities, the mermaid life state opens up storytelling possibilities that persist across generations of Sim families if players choose to lean into that angle. Mermaid Sims can pass on their nature to descendants under the right circumstances, letting dedicated players build multi-generational family sagas centered around a Sulani mermaid bloodline, complete with the social secrecy many players choose to roleplay around keeping a family’s true nature hidden from the wider island community. This kind of emergent, player-driven storytelling is a hallmark of what makes life-state additions to The Sims 4 particularly popular compared to purely cosmetic content packs.
Mechanically, mermaid abilities also interact directly with the island’s environmental systems, letting mermaid Sims influence local wildlife and even nudge the island’s overall cleanliness state in ways ordinary Sims cannot. This gives the life state a functional purpose beyond flavor, tying it meaningfully into the broader systems Island Living introduces rather than treating it as a purely cosmetic novelty layered on top of otherwise unrelated gameplay.
Family and Community Gameplay in Sulani
Sulani’s design leans heavily into community-oriented gameplay, with neighborhood-wide festivals, communal gathering spaces, and social systems that reward Sims for participating in group activities rather than pursuing purely individual goals. This community focus fits naturally alongside families with children, since many of the pack’s activities — beach cleanups, island festivals, and casual social gatherings — are built around multi-generational participation rather than solo career advancement, making Island Living a popular choice for players specifically building out large, multi-Sim households centered on shared island life rather than individual character arcs.
A Quick Word on Pairing With Other Expansions
Island Living tends to pair especially well with packs focused on nature, outdoor recreation, or cottage-style living, since their shared emphasis on slower, environment-driven gameplay complements Sulani’s relaxed pacing rather than competing with it. Players building out a broader Sims 4 collection often report the most satisfying results when combining Island Living with at least one other lifestyle-focused expansion, giving Sulani residents more varied hobbies and career options without disrupting the pack’s core island atmosphere.
Final Thoughts on Sulani’s Place in The Sims 4
Years after release, Island Living is still frequently recommended as one of the more atmospheric and distinct settings in The Sims 4’s catalog, offering a genuinely different pace and mood compared to the base game’s more suburban default worlds, making it a worthwhile addition for players looking to diversify their Sims’ lifestyles.
