When using hot tubs rented from elsewhere in OK20’s yard, please note

When filling the hot tub, ensure that the hose does not leak into the interior of the OK20 and cause water damage. If such water damage occurs, the person who made the booking will be held responsible. The rent of the facility does not include a filling hose.

The hot tubs are only allowed in the yard at the time of booking. The hot tub must not obstruct or impede access to the parking space.

In addition, when emptying the hot tub, please ensure that the tub is emptied gradually into the yard’s rainwater drain or into the soil so that pools of water or patches of ice are not formed on the passageways in winter.
