Bathroom Units and Their Installation Methods

Abstract

This invention provides a bathroom unit that allows for watertight treatment of the connection between bathroom fixtures and underfloor drain pipes from the inside of the bathroom after the base plate is laid. The base plate 12 of the main body 11 of the bathroom unit 10 is covered on the underfloor drain pipe 5 located on the floor surface 4a of the installation area 2 within the building 1. The end 5a of the underfloor drain pipe 5 faces the connection hole 15 of the base plate 12, and the base plate 12 is laid on the installation area 2. A wet sealant 50 is provided in the annular gap 18 between the inner periphery of the connection hole 15 and the underfloor drain pipe 5. Then, the cylindrical portion 32 of the connecting member 30 is inserted into the underfloor drain pipe 5. An annular clamping member 40 is pressed between the upper surface portion 12ac of the base plate 12 around the connection hole 15 and the flange portion 31 of the connecting member 30, fixing the flange portion 31 to the base plate 12.
