Book here if you're staying anyway and want a heated pool high up. It's on the 18th floor and limited to 40 people per session, but it closes in winter and non-guests can't use it.
The pool
This is an outdoor rooftop pool on the 18th floor of the hotel at 253 Gangnam-daero, Seocho District. It is heated, and the hotel has a children's pool on the same roof. Season is the limit: the hotel has announced a winter closure.
Our take
This is the only heated, guests-only pool on our list that publishes its floor. Hamilton Hotel lets outsiders in with a day pass, but here the pool belongs to people with a room. Somerset Palace is also heated and on the 18th floor, yet it doesn't say who can swim.
The downside is timing. The hotel posted a notice in November 2025 that the rooftop pool is closed for the winter season, and Seoul's average highs drop to 4.2°C in December and 2.1°C in January. Plan a stay between April and October, and aim for June to August, the warmest months.
Good to know
- 18th floor, outdoor and heated
- Children's pool on the same rooftop
- Capacity capped at 40 people per session
The catches
- The pool is closed in winter, and the hotel's own notice says so, so check dates before you book.
- Guests only, with no day pass
Best forFamilies staying in Gangnam who want a heated pool plus a children's pool on the roof.
Skip it ifYou aren't staying overnight or are visiting between November and March.
Getting in
Swimming is for hotel guests only. The hotel doesn't sell day passes, and no bar access to the pool is published.
Capacity is limited to 40 people per session, so expect to reserve a slot. A swimsuit is required for rooftop pool visits between April and October.
Tips
- Book the room for June to August, when Seoul is warmest and the pool is open.
- Reserve your pool session when you check in, since each session is capped at 40 people.
Before you go. Check that the rooftop pool is open for your dates. The hotel closes it in winter, and the last notice we have is from November 2025.
