The white-throated dippers first breed when they are one year old. They are monogamous and defend a territory. The nest is almost invariably built either very near or above water. It is often placed on a rocky ledge or in a cavity. Human-made structures such as bridges are also used. The nest consists of a dome-shaped structure made of moss, grass stems and leaves with a side entrance within which is an inner cup made of stems, rootlets and hair. Both sexes build the main larger structure, but the female builds the inner cup. The eggs are laid daily. The clutch can contain from 1-8 eggs but usually 4–5. The eggs are smooth and glossy white and are with a calculated weight of . They are incubated by the female beginning after the last or sometimes the penultimate egg has been laid. The male will bring food to the incubating female. The eggs hatch after around 16 days and then both parents feed the altricial and nidicolous nestlings. For the first 12–13 days they are brooded by the female. Both parents remove the faecal sacs for the first 9 days. The chicks fledge at around 22 days of age, but the parents continue to feed their young for another week but feeding can continue for 18 days. If the female has started a second clutch, then only the male parent feeds the fledglings. One or two broods are reared, usually in the same nest. When disturbed, the young that hardly feathered will at once drop into the water and dive.
