These structures, known in Irish as tigh alluis, were typically heated by burning turf inside until the walls were thoroughly warm, then raked out so that a person could crawl in and sweat in the residual heat. The entrance here, now destroyed, was at the south-east, and the interior dimensions of roughly 1.55 metres by 1.5 metres leave no doubt that this was a close, deliberate space rather than a casual ruin.

The site is built into an east-facing slope above a stream running south-west to north-east, with the remains of a deserted house sitting about a hundred metres to the east on the far bank. That combination, a therapeutic structure paired with a nearby abandoned dwelling, suggests a once-inhabited landscape now largely returned to rough ground. What survives today are the foundations of the square, stone-built chamber, with walls standing anywhere between ten centimetres and sixty centimetres high. Notably, the structure appears only on the 1914 edition of the Ordnance Survey six-inch map, which means it had already passed out of active use or common knowledge by the time most modern mapping was compiled, and its record since then has been thin.
