Sea House in Sofia, Bulgaria

Sea House is a specialist wellness studio at 55 Solun Street in Sofia’s Borovo area, known primarily for flotation therapy and a “sea room” rather than for a conventional sauna-and-pool spa. Current listings consistently identify the same address and telephone number, and partner platforms continue to offer Sea House sessions in 2026. It is best suited to visitors interested in a quiet, appointment-based experience such as floating in a saltwater capsule or spending a short session in the mineralized sea room. The important limitation is operational: current sources disagree about opening days, so Tuesday to Saturday is the safest common window and Monday or Sunday should be confirmed directly before travel.

Flotation is the more substantial of the two main experiences. Current booking information describes 60-, 90- and 120-minute sessions in a flotation capsule filled with warm, dense saltwater. The idea is sensory reduction and physical unloading rather than exercise or hydrotherapy in a shared pool. Visitors shower before entering the capsule, float for the booked period and shower again afterward. This format gives Sea House a very different rhythm from a gym spa: most of the visit is private and still, and the value depends on whether you actually want prolonged quiet rather than a circuit of multiple facilities.

The sea room is a shorter experience. Current booking material describes sessions of roughly 30 minutes for adults, using a room designed to reproduce aspects of a marine microclimate with mineral mist and ionized air. Sea House and its booking partners market the room for general wellness and respiratory comfort, but those claims should not be interpreted as medical treatment or a guarantee of health benefits. Travellers with respiratory conditions, pregnancy, open wounds or other concerns should follow professional medical advice and discuss any contraindications with the venue before booking.

The address is 55 Solun Street, in Borovo, near Bulgaria Boulevard. A current booking listing describes the entrance as being from Solun Street at the corner with Borovo Street, which is useful because the venue is a small specialist studio rather than a landmark building. Advance reservation is required or strongly emphasized by the partner listings. This is therefore a place to navigate to for a specific appointment, not somewhere to drop into while passing and expect immediate access to a pool or sauna.

Opening hours need careful treatment because current sources conflict. MultiSport lists 10:00–20:00 every day, Studio24 gives Monday closed, Tuesday to Saturday 10:00–20:00 and Sunday 10:00–18:00, while a recent SoFun booking page says Tuesday to Saturday 10:00–20:00 with Sunday and Monday closed. The overlapping, well-supported period is Tuesday through Saturday, 10:00–20:00. For Monday and Sunday, direct confirmation is the responsible choice. A booking confirmation should be treated as more reliable for your specific visit than any static directory timetable.

Allow more time than the treatment label alone suggests. A 60-minute float requires arrival, explanation, changing and showering before and after, so ninety minutes on site is a more realistic minimum. Longer floats can turn the appointment into a two- or three-hour block. The sea room is shorter and can fit into a compact schedule, but it still makes sense to arrive early enough to complete any intake or preparation without reducing the booked session.

Prices vary by duration and partner. Current booking platforms display separate rates for flotation and sea-room visits, sometimes with discounts tied to cards or partner programmes. Those amounts can change, so confirm the total directly when reserving rather than relying on an old directory price. Also ask what is included. Current flotation listings mention shower facilities and basic items such as robe or slippers, but a visitor should verify anything essential rather than assuming the studio supplies the same amenities as a hotel spa.

Sea House can work well after a long journey or a busy sightseeing schedule precisely because it offers stillness rather than another activity-heavy attraction. At the same time, anyone who becomes uncomfortable in enclosed spaces should ask how the flotation capsule operates before booking. Current booking information says users remain in control of the lid, but comfort is personal. A first-time visitor may prefer the shortest flotation duration rather than committing immediately to two hours.

Detailed accessibility information is not published clearly enough to state that the flotation capsule, shower or sea room is wheelchair accessible. If you need step-free entry, transfer assistance or an adapted changing area, contact the studio before paying. The same precaution applies if mobility limitations make getting in or out of a flotation capsule difficult. This is one of the cases where a short phone conversation is more useful than a generic accessibility label.

Sea House is therefore a niche wellness stop rather than an all-purpose spa. Its strength is focus: flotation for prolonged sensory rest and a shorter sea-room session at one Borovo address. Its weakness for spontaneous visitors is the need to book and the inconsistent published timetable. Reserve first, use Tuesday to Saturday as the most consistently supported operating period, and confirm Monday or Sunday directly. For travellers who specifically want flotation in Sofia, Sea House remains a clearly identifiable and currently bookable option.
