Bestway hot tub sizes and water capacity
Bestway's 20 listed models hold from 160 to 362 gallons. Find yours below for its water volume, dimensions, and seating, then size your chemicals to that figure.
One maker, several brand names. Bestway sells the same units as Coleman SaluSpa in the US and Lay-Z-Spa in the UK and Australia, so a Coleman Miami and a Lay-Z-Spa of the same body hold the same water. Match the body size (the round or square dimensions) rather than the name.
Why your gallons matter
Every chemical dose is sized from your water volume, so the gallons figure is the one number to get right before you balance the water. Open any model above for the exact doses for its volume, or take the number to the dosing calculator. Capacities are the maker's stated figures; confirm against your own manual when precision matters.
