The Bath House

The Bath House, built around 1761-1763 by Lancelot Brown, was later altered in 1797 and 1802 by J. Nash. It is constructed from rubble stone with ashlar dressings and features an ogee stone-tiled roof topped with a crocketted finial. The building has a square plan and stands two storeys tall in the Gothick style. It includes ashlar quoins and a moulded cornice that is interrupted by an ogee 'pediment' adorned with crocketted finials at the apex and sides, as well as similar finials at each corner. There are battlements between the finials, likely added by Nash.

On the first floor, three sides feature pointed Gothic windows with two lights, cusping, and traceried glazing bars. The front window is flanked by two canopied niches. The ground floor front and the bath chamber were remodeled by Nash, presenting a triple-arched front with a central four-centred arch flanked by narrower round-arched openings, all delicately moulded with pendant cusping. The structure includes quatrefoil columns and responds with moulded caps and bases, while the spandrels are fluted.

Inside, there are half-columns arranged in three by three bays, with a broad centre and narrower side bays, supporting a shallow plastered octopartite vault. A sunken bath with a moulded stone rim is also present. The front loggia is open on the sides, featuring one ogee-headed archway on each side with a hoodmould, which is a remnant of Brown's original ground floor; the stonework from the removed front arcade has been incorporated into the Sham Ruin.

At the rear, two side arches lead to the bath area, one providing access to a curving stair that leads to the upper changing room, while the other opens into a serpentine passage that connects to the walled garden behind. This passage contains four slit windows with stained glass, plastered walls, and a tunnel vault that was originally inlaid with fir-cones and moss in decorative patterns, some of which still remain. The rear stair tower is curved and topped with a curved stone-tiled roof, and the passage also features a stone-tiled roof.
