In short, it can take up to around two weeks for the tub to fully seal. In general, when you first start filling your new tub, you may experience a range of leaking levels, from no leaks to several spots with running leaks and several more spots with drips. If you followed the assembly procedure correctly, there’s no cause for panic. The biggest changes will occur during the first two days of the tub being full of water and kept full of water. After two days, you should not have any running leaks, only drips. Click here to view our hot tub assembly manual with additional details under Section 11: Adding Water.
