Hyatt Regency Pravets Resort

Single-swim admission is not available to members of the general public, unless registered as guests at the hotel.

Registered guests: Free.

In addition to the hotel's indoor pool, there is a 50m x 21m outdoor pool on the parcel between the hotel and the building identified on the Google Map as "bowling Pravets"; the pool appears to be a public one.

Not to mention that the hotel is located on a lake that's approximately 1 kilometer long. The hotel's website doesn't say anything about it, and it doesn't look like the lake has any beaches, but both the outdoor (public?) pool and the bowling alley have pier-type structures over the lake.
