ABSTRACT:
A hot tub or spa (100) has a vanishing or overflow edge (110) not readily visible to a user. Water from the main holding area (101) overflows the edge (110) into a catch basin (102). A reservoir (120) holds a constant head of water to provide to a pump (112) and also allows for the holding of increased amounts of water displaced by users who are using the hot tub (100). Water flowing over the vanishing edge (110) flows into the catch basin (102) and thence to the reservoir (120) and pump (112) where the water is recirculated into the spa (100).
