Heating Studio
히팅스튜디오 Hiting Seutudio The name is the English word 'heating' — the studio's own posts call it a place where anyone who loves bread and coffee makes their own warmth (온기, Heating), under the slogan 'Rule the Oven'.

A shared baking and barista studio on the third floor (unit 303) of Seongdong Ansim Sangga, Seongsuil-ro 12-gil 20, Seongsu-dong. It sells no food: you rent ovens, proofers, mixers and espresso machines by the hour and bake or pull shots yourself. We read 20 posts from October 2024 to September 2026; 8 were written by people who used the space. Ten were the studio's own notices, class posts and recipes, and we did not count them. An April 2026 post gave the barista area at 14,000 won an hour with a three-hour minimum.

Counted from what bloggers wrote in their posts; we did not confirm it with the restaurant. Where the values differ, it may be a change over time rather than a disagreement, so we show when each one was written.
What sets it apart
- All 4 visitor posts that mentioned the people running it said they were helpful. One first-timer said they fumbled around and still finished thanks to the owner; another said staff explain things patiently, perhaps because many beginners come; a third, baking 300 levain cookies, said the owner made extra room in the freezer and ovens.
- People come back. 4 visitor posts record repeat visits: a fourth visit, several returns after a first class, a writer who calls it their regular latte-art practice room, and one who baked 100 cookies on each of three days. These are mostly people practising alone what they learned at baking or barista school.
- You must finish and clean up inside your booked slot; 2 visitor posts say so. One writer went an hour early to mix dough because salt bread plus cookies would not fit in three hours, and still nearly ran out of time. The other says cleanup has to start 20 minutes before the end.

Where it is
We could not find this shop’s own listing on Naver Map, so the link searches for its Korean name around this spot instead.

Getting inside
| In a basement | yes 0 · no 1 (of 7 posts read) |
|---|
Only one visitor described the floor: the building is large and they circled around before finding unit 303 on the third floor. It is not in a basement.
We do not know whether there is a lift to the third floor, a step at the door, or wheelchair or stroller access. Not one of the 20 posts mentions it.
We do not know whether the toilet is inside the studio or shared in the building, or whether it is split by gender. No post says.
No one mentioned: Second floor · Lift to the floor · Ramp at the door · Step at the entrance · Step-free access · Toilet inside · Accessible toilet · Separate restrooms. That is not the same as there being none — it means we could not confirm it. Worth calling ahead, and do tell us: we will put it here.

Posts that followed a TV spot
Of the 19 posts we gathered, 12 went up on a single day right after a TV spot and show no sign of a visit. They retell the broadcast, so we left them out of the counts.
We do not discard them. That a TV spot produced a burst of posts is itself something worth knowing about a place, and a star rating will not show it.

What we do not know
- Two posts called it spacious, but the baking and coffee areas share one open room rather than being separate rooms. An April 2026 visitor said the owner and friends held a meeting at the table right in front of the coffee area the whole time, so it never felt private. Exclusive use means booking a full hire.
- Only 1 visitor post mentions getting there, saying it is handily near Seongsu Station. The studio's own directions (Seongsu exit 1 or Ttukseom exit 4, under ten minutes on foot) are its own claim, and we did not count them.
- No post mentions waiting. Sessions are booked in advance on Naver, so we cannot say whether there is ever a queue. A 2026 studio post said regular bookings open one to two weeks ahead.
- Who people came with does not settle into a pattern: one came alone, one as a couple, one with friends.
- Opening hours: 2 visitor posts both give 10:00–20:00, but both copied the studio's notice, and they disagree about Sunday — one says Sundays are for full hire only, the other says the studio is closed every Sunday.
- Prices appear in only 2 visitor posts: 14,000 won an hour for the barista area (April 2026) and 3,000 won per person for basic ingredients (June 2026). Nobody gave the baking-area rate, and the studio says full-hire rates changed on 1 August 2026 without stating the amounts.
- No phone number appears across the posts. Bookings go through Naver Reservation and enquiries through the KakaoTalk channel @히팅스튜디오.
- Ten of the 20 posts come from the studio's own blog: hire notices, equipment lists, class sign-ups and recipes, two of them a templated recipe series with Coupang affiliate notices. Claims there about roomy benches, full equipment and friendly advice are the studio's own, and we did not count them.
