Wells House is a large former hydropathic establishment and hotel in Ilkley, West Yorkshire, England, now used as private apartments.

It is located above the town on Wells Road at the edge of Ilkley Moor, giving it an unobstructed view across Wharfedale from its north front.

Wells House possesses a monumental and sombre character, constructed in dark local stone using an Italianate style influenced by the work of John Vanbrugh and Charles Barry.

[3] Its original health purpose was to offer cold baths and water treatments, which were popular in the 19th century when Ilkley was a fashionable and affluent spa resort.

[4] Ilkley's first hydropathic establishment, designed around the principles of hydrotherapy or the cold water cure, a Victorian health fad which emerged in the early 1840s, was the Ben Rhydding Hydro, at Wheatley in 1843–4.

[5] A group of Bradford businessmen, led by Benjamin Briggs Popplewell, formed the Wells House Hydropathic Company and acquired land,[6] and in February 1854, commissioned the Hull-born and Leeds-based Cuthbert Brodrick to design their building.

The building subsequently found a new use as a hotel for the next seventy years; this featured a Winter Gardens with sprung dance-floor, raised bandstand, and a 3-span roof supported by decorative arched cast-iron trusses built on top of the terrace.

[4] The site (including ancillary buildings) which contained around 100 staff and 400 students, was considered too expensive to run and it was closed and sold in 1999.

Internally, the accommodation was spacious, featuring a hall with a cantilevered stair at each end with cast-iron balusters of unusual design using geometric shapes.
