An apparatus for hydro-therapy massage characterized by a low profile enclosure structure surrounding a user support surface at a nominal elevation thereabove. The apparatus comprises a housing structure having an outwardly facing opening, a user support surface covering the opening, and a fluid spray arrangement within the housing structure for imparting a massaging effect through the support surface to a user thereon. The housing structure has a horizontal perimeter flange extending about the opening and a clamp plate affixed in substantially parallel superposed facing relation to the perimeter flange for clamping a continuous edge margin of the user support surface. An enclosure panel has an essentially planar mounting flange affixed in substantially parallel superposed facing relation to the clamp plate and has a skirt portion extending from the mounting flange for enclosing the housing structure.
