Sopot Family Hotels with Indoor Pools
8 family-friendly hotels with indoor pool in Sopot . Handpicked for families who want the best.
Sopot has a Baltic problem and a Baltic solution. The problem is that even in July, the sea sits at 18 degrees and the wind off the pier can flip a parasol. The solution is the indoor pool floor that nearly every serious Sopot hotel built into its spa wing, because the locals figured out decades ago that families need a backup plan. The five hotels below all sit within a 10-minute walk of the beach, all keep their pools heated to 28 degrees or warmer, and all let kids in at the times that actually work for parents. You book Sopot for the sand and the pier, then you use the indoor pool every single morning before breakfast.
Sopot is a beach town with a casino, a wooden pier longer than any other in Europe, and a single pedestrian street called Monte Cassino that families walk three times a day. The vibe is bourgeois Baltic, more Bognor with a sauna than Saint-Tropez. Outside school holidays it goes quiet by 9pm. Restaurants here understand kids early dinners and bring crayons without asking.

🏊Why Sopot Works for Families with Indoor Pools
An indoor pool is close to essential for a family stay in Sopot: the Baltic stays cool for much of the season and the wind can turn a beach day grey within an hour. With a heated pool at the hotel, children swim every day whatever the weather, and the beach becomes a bonus rather than the only plan. Eight hotels here have one, and several add a shallow end, a kids' pool or clear age rules for families.
For young children, three pools stand out. Sopot Marriott Resort & Spa, rated 9.1 and 50 metres from the sand on the Karlikowo dune walk, has two indoor pools with a proper shallow end. Radisson Blu Hotel Sopot, also rated 9.1, has a dedicated kids' pool and direct walking access through its garden to Aquapark Sopot. Hotel Sopot - Hotel, Conference & SPA, rated 8.7, places a children's pool inside its main spa zone, next to a large play room. Each gives toddlers water they can stand in, which matters more than size when children are small.
Hotel Haffner Resort & Spa offers the most reassuring set-up for parents: a vaulted indoor pool in the basement spa wing of a renovated 19th-century building, open to children over four until 8pm, with lifeguards on duty at peak hours. Rated 9.0 from more than 2,600 reviews, it is only a short walk from the sandy beach and the pier. Its name recalls Jean Georges Haffner, who opened Sopot's first bathing establishment in 1823, and the hotel keeps the same idea alive: water first, whatever the Baltic weather does outside.
Two hotels at the pier pair their pools with a view. Sheraton Sopot Hotel, rated 9.0 from nearly 3,000 reviews, has a glass-fronted indoor pool looking straight at the Baltic, and its Wellness Bay spa lets children over eight join the swim circuit with a parent. Sofitel Grand Sopot, the 1927 grand hotel rated 9.0, has an indoor heated pool beside a sauna village in a wellness wing built beneath the hotel, plus a private gate to the beach. Both suit families who want the pool, the pier and Monte Cassino street within a few minutes.
Away from the seafront, Hotel Testa and Sopotorium Hotel & Medical Spa combine an indoor pool with strong kids' clubs. Hotel Testa, the best rated on this list at 9.4, has a kids' floor with rooms for crafts, free play and toddler soft-play, plus a spa. Sopotorium, a 4-star rated 9.1, adds a soft-play room, a craft studio and daily animation, on a quiet street about ten minutes from the seafront. For a rainy week, these two let a family move between the pool and the play rooms without going outside at all.
Parent's take
I recommend Sopot Marriott Resort & Spa for a family with toddlers: its two indoor pools include a proper shallow end, and the beach is only 50 metres away on the Karlikowo dune walk for the warmer hours. For parents who value supervision, I would choose Hotel Haffner Resort & Spa, where lifeguards watch the vaulted pool at peak hours and children over four can swim until 8pm.
Our Top 8 Picks
Hotels in Sopot with indoor pool, sorted by guest rating.
Hotel Testa
Sopot
Wonderful
315 reviews
Newer 5-star with the highest review score on this list and a thoughtfully designed kids floor — separate rooms for craft, free play and toddler soft-play, with full-day animation seven days a week in peak season. The newest interiors in Sopot and one of the better kids menus we have seen.
From
€435/night
Why families love Hotel Testa
Recent reviews from parents call out the staff-to-kid ratio in the kids club — typically one staff member per six kids, which is genuinely good for Europe. The toddler soft-play has cushion blocks and an enclosed crawl tunnel, useful when you have an under-2 alongside older siblings. The hotel is newer than most, so finish is fresh, but the location is slightly further from the pier (10-minute walk). Restaurant kids menu is one of the more inventive in town.
Sopot Marriott Resort & Spa
Karlikowo (south beach)
Wonderful
1,481 reviews
Beachfront Marriott 50 metres from the sand with two indoor pools and a proper kids' shallow end. The Scandinavian-style architecture blends into the Karlikowo dune walk and the spa floor includes a sauna circuit kids over six can use with a parent.
From
$362/night
Why families love Sopot Marriott Resort & Spa
The southern Sopot location means quieter sand than the pier end and a 12-minute walk to Monte Cassino. Family rooms sleep four with bunk beds in the second area. Pool deck is large enough that the splash zone never spills into the lap pool, and the on-site Italian restaurant runs a real kids menu with portioned pasta. Worth the extra zloty over the city-centre options.
Radisson Blu Hotel Sopot
Karlikowo (Aquapark Sopot border)
Wonderful
2,285 reviews
Modern Radisson 300 metres from the beach with a dedicated kids' pool and direct walking access to Aquapark Sopot through the back garden. Rooms come standard at 28 square metres which is bigger than any other hotel on this list.
From
$267/night
Why families love Radisson Blu Hotel Sopot
Best value of the five. Standard rooms are huge so you can fit two kids and a stroller without paying for a suite. The kids' pool is shallow and warm at around 32 degrees with bubble jets and a slide. Bonus the Aquapark Sopot entrance is a 5-minute walk through the garden, the hotel sells discounted day passes at reception. Breakfast buffet is the weakest of the five but everything else punches above the price point.
Sopotorium Hotel & Medical Spa
Sopot Upper
Wonderful
2,387 reviews
Large 4-star spa-and-medical complex with one of the most extensive kids clubs in Sopot, including a soft-play room, a craft studio, daily animation and free childcare slots for paying guests. Sits on a quiet street ten minutes from the seafront.
From
€412/night
Why families love Sopotorium Hotel & Medical Spa
Parents in 2,300 reviews single out the daily kids club programme, which runs morning craft, afternoon mini-games and evening mini-disco. The spa-and-medical side of the hotel makes it easy to book a treatment while kids are supervised — combinations rare in Sopot. A few reviewers note rooms vary a lot by category, with the standard rooms feeling dated. Pay up to a 'Premium' room category if you want the renovated look.
Sheraton Sopot Hotel
Dolny Sopot (pier district)
Wonderful
2,959 reviews
Glass-fronted Sheraton right beside the Sopot Pier with an indoor pool that looks straight at the Baltic. The Link@Sheraton family lounge has board games and the in-house Wellness Bay spa lets kids over 8 join the swim circuit with a parent.
From
$449/night
Why families love Sheraton Sopot Hotel
Closest five-star to Monte Cassino at 200 metres so you walk everywhere. Indoor pool is glass-walled with views over the Baltic, smaller than Marriott but rarely crowded outside the 5-6pm window. Free buffet breakfast runs until 11am which saves the morning for slow risers, and the concierge holds strollers if you head to Gdansk for the day. Slightly business-tinted on weeknights.
Sofitel Grand Sopot
Dolny Sopot (private beach access)
Wonderful
1,316 reviews
1927 grand hotel with the original ballroom, private beach gate and a wellness wing built underneath. The indoor heated pool sits beside a sauna village and the historic terrace looks straight at the Sopot pier.
From
$476/night
Why families love Sofitel Grand Sopot
Old-school glamour without the stiffness. The private beach gate is the killer feature, families walk out the back door and onto sand without crossing a road. Indoor pool is smaller than the Marriott but rarely busy because most guests use the Baltic. Family suites with separate kids' room exist on floors 3 and 4 but they sell out fast for summer dates. Worth the price for the historic atmosphere alone.
Hotel Haffner Resort & Spa
Dolny Sopot (Haffnera Street)
Wonderful
2,657 reviews
Renovated 19th-century building with a vaulted indoor pool in the basement spa wing. Kids over 4 are allowed in until 8pm and the hotel hires lifeguards during peak hours which is unusual for a hotel of this size.
From
$364/night
Why families love Hotel Haffner Resort & Spa
Smaller than the chain hotels but more characterful. The vaulted basement pool feels like a Roman bath and the kids treat it as a small adventure. Triple rooms sleep three comfortably and connecting doors are available on request. Restaurant runs proper Polish kids menus including pierogi sized for small mouths. Plus the price is roughly 20% under the comparable Sheraton or Sofitel.
Hotel Sopot - Hotel, Conference & SPA
Sopot North
Excellent
1,147 reviews
4-star conference-and-spa with a generously sized play room, a children's pool inside the main spa zone, and timed kids club sessions Monday-Friday in summer. Position is quieter than the seafront — five minutes by tram from the pier — and works for families who want indoor space.
From
€275/night
Why families love Hotel Sopot - Hotel, Conference & SPA
Parents like the indoor children's pool — a real benefit on the Baltic where outdoor swimming is short-season. The play room has a soft-floor section for under-fives and a Lego-and-craft table for older kids, with timed supervised sessions in summer. Spa access for kids over 12 is included with family rooms, which is unusual for Polish hotels. Some reviewers note the conference side means quiet lobby hours can be hard to predict.
💡Parent Tips for Booking an Indoor Pool Hotel in Sopot
- 1Check each pool's age rules: Hotel Haffner admits children over four until 8pm, the Marriott's sauna circuit takes children over six and the Sheraton's swim circuit children over eight.
- 2Choose Sopot Marriott Resort & Spa, Radisson Blu Hotel Sopot or Hotel Sopot for toddlers, as they have a shallow end or a separate children's pool.
- 3Swim in the late afternoon at the Sheraton, when the glass-fronted pool looks out over the Baltic and the pier.
- 4Book Hotel Testa or Sopotorium Hotel & Medical Spa for a rainy week, since both pair the pool with kids' clubs and play rooms.
- 5Pair a pool morning at Radisson Blu Hotel Sopot with an afternoon at Aquapark Sopot, reached on foot through the hotel's back garden.
- 6Keep beach time for the calmer, warmer hours and use the indoor pool when the Baltic wind picks up, a common pattern on the Sopot coast.
