Pithead baths at Lynemouth Colliery including offices and canteen (now the medical wing)

The pithead baths at Lynemouth Colliery, which include offices and a canteen (now the medical wing), were built in 1938 by F.G. Frizzell. The building features a pebbledashed exterior over white brick, with roofs that are part concrete slab and part glazed, particularly over the baths section, which is set behind a parapet. The structure has an irregular plan and is designed in the Modern Movement style.

It consists of a group of blocks of varying heights surrounding a tall central tower that has a rounded, glazed stair turret. The walls are mostly sheer, with a plinth and a slight roof projection. To the east of the tower is a long block that houses the ingoing locker room, which features a central south projection with glazed, banded steel double doors beneath a high strip of windows that extends over the eaves. A taller storeroom to the west has similar doors set in two recessed banded glazed bays and connects to the south-east corner of the tower. The base of the tower also has double doors.

On the west side of the tower is a large lower canteen wing that has banded glazing around two sides above a projecting sill. To the north, a slightly projecting three-bay office section includes steel cross casements, and on its return, there is another casement and a door with hollow-chamfered jambs and a flat hood. Behind this is the taller bath block, which features a wave pattern on the rainwater heads.

Inside, the walls and doors in the canteen and office section are flush, with some tiling that may have been renewed. The doors have a single architrave moulding, and exposed service piping runs throughout. In the baths section, the ingoing ('dirty end') and outgoing ('clean end') locker rooms contain slatted steel lockers with polished metal mirrors on the locker doors. The shower cubicles are finished with white tiles, and the walkways have white tiles topped by a single band of red, with stop-chamfered lintels.
