How we compared
Prices and specs are the lines on each maker's page on Oct 26, 2026. Shipping is included only when that page states a shipping figure or says shipping is included. If a page does not state a figure, the cell says not listed. Plunge publishes no product page named Sport or Pro: /products/plunge-sport and /products/plunge-pro returned 404 that day, so those names are not rows. Edge Theory Labs' homepage says the company has gone out of business, and the Edge Tub Elite URL returned 404, so that maker is not in the table. If a page changes, the page wins.
