Adelaide Hotels With a Heated Indoor Pool
In Adelaide, all five hotels on this page keep a heated indoor pool inside the CBD grid, which matters from May to September, when winter days in the city stay cool and outdoor hotel pools are rarely swimmable. For real laps, the Adelaide Marriott's 18 m pool in the old General Post Office building on King William Street is the longest I could confirm. The Playford on North Terrace has a 12.5 m pool heated to 26°C with a spa and sauna, open 24 hours to guests. Sofitel Adelaide heats its Level 5 lap pool to between 26 and 30°C behind floor-to-ceiling windows. Avani Adelaide Residences and Peppers Waymouth add heated indoor pools near the Central Market. The five average 8.8 out of 10 across 6,996 guest reviews.
Adelaide is a compact, flat CBD laid out in a grid between North Terrace and South Terrace, with the free city tram along King William Street and the Glenelg tram out to the beach. Its hotel pools sit indoors because the summers are hot and dry and the winters cool, so the water stays useful in both.
Where to stay
Which Adelaide indoor pool fits your swim
Adelaide's hotel pools are almost all indoors and heated, which turns a winter city break into a swimming one; the real choice is between length, temperature, hours and what comes with the pool.
Can you actually swim laps in an Adelaide hotel pool? At the Adelaide Marriott, yes: its heated indoor pool measures 18 m, the longest of the five I could verify, and it sits inside the historic General Post Office building at 141 King William Street. The pool is open from 6 am to 10 pm, with loungers along the side and a design built for swimming rather than for photos. The hotel scores 9.1 from 513 reviews, the highest rating here, though it has the fewest reviews. If laps are the reason you book, this is where I would sleep.
For a late-night swim, The Playford on North Terrace is the one. Its health club, with a heated indoor pool, spa, sauna and gym, is open 24 hours a day to hotel guests only, so the water never fills with day visitors. The pool is short, 12.5 m, kept at 26°C, which suits a slow swim and a sauna after a show at the Adelaide Festival Centre more than training. The hotel sits directly opposite the Adelaide Convention Centre and carries a 9.0 score from 2,006 reviews, the most consistent big sample of the five.
Sofitel Adelaide has the warmest and most photogenic water. The hotel heats its lap pool on Level 5 to between 26 and 30°C, lights it with chandeliers and opens it to the city through floor-to-ceiling windows; the gym on Level 6 overlooks the water. That temperature range makes it the pool I would choose with young children or in the middle of July, when cooler water feels cold the moment you step out. The hotel is on Currie Street, at the western end of the CBD, and scores 8.8 from 1,013 reviews.
Avani Adelaide Residences is the pick for a longer stay or a family that wants a kitchen. It is an aparthotel at 176 Franklin Street with apartment-style suites, a heated indoor lap pool, a steam room and a sauna, and it is a short walk from the Adelaide Central Market, so breakfast can come from the stalls. It scores 8.6 from 1,326 reviews. I could not find a published pool length, so serious swimmers should not book it for distance alone; for a morning swim before work, it does the job.
Peppers Waymouth, on Waymouth Street, packs an indoor heated pool, a spa pool and a sauna with a 24-hour gym, and it is a short walk from both the Central Market and Rundle Mall. With 2,138 reviews it has the largest sample here, scoring 8.6. It suits a couple who want warm water and heat after a day on foot more than a swimmer counting lengths, since the hotel does not publish its pool size. Between Peppers and Avani, I would choose Peppers for the spa and sauna, and Avani for the kitchen.
A traveler's takeIf I wanted to swim properly in Adelaide, I would book the Adelaide Marriott for its 18 m pool and plan my swims between 6 am and 10 pm. For a winter weekend with a show and late dinners, I would choose The Playford instead, because the pool, spa and sauna stay open all night to guests. With small children in July, the Sofitel's water at up to 30°C on Level 5 would win. I would not pick Avani or Peppers for laps without asking the hotel for the pool length first.

City-centre luxury with an indoor pool and modern Australian dining
Why guests love itThe Adelaide Marriott Hotel holds a 9.1 rating as a dependable five-star base right in the city centre, with an indoor pool that works regardless of Adelaide's swing between dry summer heat and cool winter mornings. The fitness centre and restaurant round out a stay built around convenience rather than spectacle. It suits travellers who want a polished, central hotel with a pool they can actually use daily, more than a resort-style splash pad for lounging.
